How to reproduce, the mode of reproduction / sowing / cutting / ramet

Drunken fish grass is a kind of flower plant of Brucaceae, which can be seen in all provinces of our country. With more and more people raising it, people are more concerned about its reproduction. How to reproduce it? What are the breeding methods of drunken fish grass? Next, the editor will take you to learn about it.

How to reproduce, sow / cuttage / ramet

When it comes to how to reproduce the drunken fish grass, in fact, it is mainly divided into three methods: sowing reproduction, cutting propagation and split propagation. As long as we operate properly, the three methods are highly ornamental. As for the specific details and operation methods of the three breeding methods are described in detail below, let's take a look.

Second, the breeding mode of drunken fish grass

Sowing and reproduction

Seed prompt: the fruiting rate of drunken fish grass is very high, and its seeds usually mature 2-3 months after flowering, then we can take it out, take out the outer skin, take out the seeds, and then soak them in warm water for about 12-24 hours. when the seeds begin to absorb water and expand, they can be taken out and sown, which can promote the seeds.

Sowing and reproduction: before sowing and reproducing, we should first apply appropriate amount of base fertilizer to the substrate, and then sow the seeds evenly on the soil surface. After sowing, we can cover the soil with 1-2cm for watering, watering carefully, and then put it at a temperature of 20-25 ℃ for 3-5 days.

Cuttage propagation

Cuttings selection: the selection of cuttings also has a great impact on the survival rate of cuttings. Generally speaking, it is better to choose branches with relatively robust growth and no diseases and insect pests as cuttings. If the branches we choose look very slender, then we can basically judge that the cuttage failed, so the selection of cuttings is a very important step.

Cutting method: in the propagation mode of drunken fish grass, cutting propagation is a relatively simple method. First of all, we can use chopsticks to cut a hole in the soil, so that the cuttings can be inserted into the soil 2/3 for watering. When watering, pay attention to watering thoroughly, remember not to cause stagnant water.

Ramet propagation

The ramet propagation of drunken fish grass can generally be carried out in combination with changing pots. When we split the plant, we can lift the overgrown mother plant out of the basin soil, then cut it into several clumps, put it on the pot separately, and plant along with it. It is very easy to survive. Generally, after the pot is a complete pot of foliage flowers.

Drunken fish grass Buddleja lindleyana Fortune drunken fish sketch guide: drunken fish grass how to raise / how to reproduce drunken fish grass name piece drunken fish grass Buddleja lindleyana Fortune drunken fish grass introduction of drunken fish grass (Buddleja lindleyana Fortune), transition flower order Loganaceae plants. It is native to tropical and subtropical regions of the world. Most species of the genus Cyperus have hairy or furfurous leaves and flowers in clusters of purple, white, yellow or orange. Drunken fish grass, alias fish tail grass, drunken fish grass, is a labial order, Scrophulariaceae, drunken fish grass plants. Deciduous shrub, 1-2.5m high. Bark tea-brown, much branched, branchlets quadrangular, narrowly winged. The florescence is from April to July and the fruiting period is from October to November. Drunken fish grass, verbenaceae drunk fish grass is a semi-evergreen shrub. More cold-resistant (in Shanghai area to withstand the absolute lowest temperature-8 ℃, the suitable temperature for growth is 25: 30 ℃, but also can withstand the high temperature of 39 ℃), strong drought resistance, lax soil quality requirements, extensive management, like sufficient sunshine, flowering is the most luxuriant in fertile and well-drained places. It should be pruned after flowering every year to ensure exuberant growth in the coming year. It blossoms continuously from the end of spring to frost, with large and gorgeous inflorescences, long flowering period and luxuriant flowering. It is an excellent summer and autumn shrub. Drunken fish grass cultivation is easy, convenient management, no matter group planting or scattered planting, can form a better natural landscape. The morphological characteristics of drunk fish grass is a shrub with a height of 1-3 meters. Stem skin brown; branchlets quadrangular, slightly narrowly winged above ribs; young branchlets, leaf blades, petioles, inflorescences, bracts and bracteoles densely covered with stellate tomentose and glandular hairs. Leaves opposite, leaves on budding branches alternate or subwhorled, leaf blade membranous, ovate, elliptic to oblong-lanceolate, 3-11 cm long and 1-5 cm wide, apex acuminate, base broadly cuneate to rounded, margin entire or with wavy teeth, dark green above, stellate pubescent when young, glabrous, gray-yellowish green below; lateral veins 6-8 on each side, flattened above, sunken after drying, slightly raised below Petiole 2-15 mm long. Spikes terminal, 4-40 cm long and 2-4 cm wide; bracts linear, up to 10 mm long; bracteoles linear-lanceolate, 2-3.5 mm long; flowers purple, fragrant; calyx campanulate, ca. 4 mm, outer and Corolla covered with stellate hairs and scales, inner surface glabrous, calyx lobes broadly triangular, long and wide ca. 1 mm Corolla 13-20 mm long, inner surface pilose, Corolla tube curved, 11-17 mm long, upper 2.5-4 mm in diameter, lower diameter 1-1.5 mm, Corolla lobes broadly ovate or suborbicular, ca. 3.5 mm, ca. 3 mm wide; stamens inserted in lower part of Corolla tube or near base, filaments very short, anthers ovate, tip pointed, base auriculate Ovary ovate, 1.5-2.2 mm long, 1-1.5 mm in diam., glabrous, style 0.5-1 mm long, stigma ovoid, ca. 1.5 mm.

Infructescences spicate; capsule oblong or elliptic, 5-6 mm long, 1.5-2 mm in diam., glabrous, scaly, base often with persistent calyx; seeds light brown, small, wingless. The florescence is from April to October and the fruiting period is from August to April of the following year. The ecological habits of drunken fish grass like warm and humid climate and deep and fertile soil, strong adaptability, but not resistant to water and moisture. Drunken fish grass has strong stress resistance, cold and heat resistance, water saving and drought resistance. When the temperature is as high as 40 ℃ and-15 ℃, it can grow normally, survive the winter safely, and can bear the low temperature of-30 ℃. The temporary wilting coefficient of the leaves of Scutellaria alternifolia is 1.292%, which is extremely resistant to drought. It is irrigated 3 to 4 times a year in areas with annual precipitation of 180 mm to 400 mm, and irrigated once or twice a year in areas of about 400 mm. It can grow and blossom. It is a good ornamental plant for water saving and drought tolerance. The cultivation technology of drunken fish grass is whirling branches and leaves, luxuriant flowers, elegant fragrance, suitable for planting on slopes, bridgeheads, walls, or as medium-sized hedges, or grass clusters, dense planting as flower hedges, flower belts. Sowing, cutting or split-plant propagation by cultivation. Because the seed is small, it is suitable for sowing in a high bed, pay attention to moisturizing and setting up a shed to shade the sun, and grow large when the seedling is as high as 10 cm. The cuttage of drunken fish grass can be carried out in spring, using dormant branches as cuttings. Ramet combined with transplantation is easy to survive. In cultivation, the aboveground parts can be cut off during the dormant period, so as to produce new branches and bloom more in the following year. The breeding method has strong adaptability, resistance to barren soil, salt and alkali resistance: lax requirements for soil, and grows well in loam, sandy loam, gravel soil with good soil permeability. Resistant to barren soil, when the content of soil organic matter is more than 0.3%, the annual growth can still reach 33 cm. Normal growth and flowering can be achieved when the pH value is below 9 and the salt content is below 0.3%. Strong stress resistance, cold and heat resistance, water saving and drought resistance: it can grow normally when the temperature is as high as 40 ℃ and-15 ℃, can survive the winter safely, and can bear the low temperature of-30 ℃. The temporary wilting coefficient of the leaves of Scutellaria alternifolia is 1.292%, which is extremely resistant to drought. It is irrigated 3 to 4 times a year in areas with annual precipitation of 180 mm to 400 mm, and irrigated once or twice a year in areas of about 400 mm. It can grow and blossom. It is a good ornamental plant for water saving and drought tolerance. Xue Jinze has tough and strong branches, exuberant growth, blooming, colorful flowers, resistance to pruning, suitable modeling, strong ornamental: through reasonable pruning, the plant type is compact and the flowering period is long. solitary planting, hedge planting, belt planting, slice planting and other ways can be used in parks, roadside green spaces and both sides of the highway, resulting in a kind of momentum beauty. It is easy to propagate, simple and extensive in cultivation and management, and ∶ can be sown, cut and propagated by tissue culture, especially the tender wood cuttings can easily survive and blossom 2 ~ 3 years after cuttage, and the effect is quick. Extensive management during the growing period, no need for overwintering protection measures such as cold prevention, less diseases and insect pests, which can reduce the cost of control and pollution to the environment, strong branching ability, resistance to pruning, generally suitable for pruning after flowering, and very little fertilization. apply rotten base fertilizer before planting. The best propagation method of drunken fish grass is the softwood cutting in May and June growing season. The survival rate is high, the growth is fast and the reproduction is rapid. Set up a shade shed before cutting, disinfect the river sand in the bed with potassium permanganate or carbendazim, cut the semi-lignified branches into 10 cm long segments, remove all the lower leaves and cut off 2/3 of the upper 2-3 leaves. The upper cut is 1 cm away from the bud, and the lower cut is obliquely cut into a horseshoe shape on the back of the bud. Use a piece of wood to cut a ditch 5 cm deep in the river sand, put the cuttings dipped in the rooting agent neatly, cover with sand, and spray water. Cutting density to leaves do not touch each other, uniform distribution is appropriate, after the whole bed has been planted, and then spray again through water, and then build arch shed cover plastic film, all around closed. Spray water twice a day before taking root in order to cool and moisturize, keep the temperature in the shed about 28 ℃ and the relative humidity above 90%. It took root in about 20 days in May and June, and began to take root in July and August. After rooting, control moisture, pay attention to ventilation, according to the rooting situation, remove the arch shed. The seedlings were transplanted after a week. The bare roots of the seedlings after rooting by cuttings must be carefully cultivated in the nursery. In order to prevent the occurrence of diseases and insect pests, 3kg ~ 4kg of phoxim particles and 50kg of ferrous sulfate were applied per mu. Follow the word "fast" when transplanting, transplant quickly, and irrigate one bed after planting. Because the drunken fish grass grows fast, the row spacing should not be too small, and it is appropriate to take 35 cm × 50 cm. After transplanting, cover the seedlings directly with sunshade net for 2-3 days, remove the sunshade net and water again in the afternoon 3 days later, and so on when the ground surface is slightly dry, paddle and hoe once again to preserve soil moisture. After 7-10 days transplanting seedlings can survive, 2 months later a colorful scenery will appear in front of us. Common varieties of drunken fish grass 1.

Water-fried clothing, ("unilateral prescription investigation data selected") ② treatment of hookworm: drunken fish grass five dollars (children appropriate reduction). Boil for two hours, take 100 ml of juice, add sugar, and take it separately after dinner and before the morning meal. The dosage can be increased from five dollars to five taels one by one. Individual patients have symptoms such as nausea, abdominal pain, diarrhea, dizziness and fatigue. ("selected Infectious Diseases of the full Exhibition") ③ to treat malaria: drunken fish grass, one or two of Radix Scutellariae. Water frying should be taken within three to four hours before the onset of malaria for two days. (selected data of unilateral prescription investigation) ④ treats new injuries: fresh drunken fish grass and whole grass, five to eight dollars (three to five dollars dry). Add red wine and boiled water and simmer for an hour. Take internally. ("Fujian Folk Herbal Medicine" ⑤ treats traumatic bleeding: drunken fish grass leaves are dried in the sun and sprinkled on the wound, and gently pressed, which has the effect of stopping bleeding. ("Fujian Folk Herbal Medicine") ⑥ treats accidental eating grouper roe (medium) poison, vomiting more than: fish tail grass juice to take a little. ("Puji Fang") ⑦ treats gills: five dollars for drunken fish and grass, seven maple balls, and three dollars for shepherd's purse. Boiled eggs. (Hunan Pharmaceutical Chronicles) ⑧ treatment: drunken fish grass whole grass one or two. Pan-fried suit. (Hunan Pharmaceutical Chronicles) ⑨ treats cold toothache: fresh drunken fish grass leaves and a little salt, smash and take juice to gargle. (Fujian Chinese Herbal Medicine) Clinical Application 1. Compound drunken fish grass tablets were used to treat chronic bronchitis, 8 tablets each time, 3 times a day (5.3 yuan for daily dose, 4.7 yuan for Zijinniu, 2.6 points for Daphne genkwa), 10 days as a course of treatment. The curative effect is obvious after medication, cough is generally relieved after 3-5 days, purulent sputum becomes thin, easy to cough, wheezing is relieved, but can not be completely controlled. Side effects include stomach discomfort, dry tongue and pharynx, intestinal flatulence, and individual complaints of dizziness, which disappear after drug withdrawal. two。 Take drunken fish grass decoction for the treatment of bronchial asthma, twice a day, 2 taels each time. In one case, a large amount of yellow pus-like sputum was vomited 10-15 minutes after each treatment, and the chest tightness was significantly improved after about 2 weeks. The symptoms gradually disappeared after taking the medicine for one and a half months (the total dose reached 6 jin). The follow-up patients returned to work 3 months later, although they did not occur when the weather changed, and the breath sounds of both lungs were checked. The function is mainly for expelling wind and dehumidification, relieving cough and resolving phlegm, dispelling blood stasis and killing insects. Bronchitis, cough, asthma, rheumatoid arthritis, fall injury; external use to treat trauma, bleeding, burn and scald, and to kill maggots. The usage costs 3% to 5%. Apply proper amount for external use, mash or powder the affected area. Precautions 1. Pregnant women should not take it. 2. Poisoning phenomena such as vomiting, dyspnea, tremor of limbs and so on are caused by excessive consumption of livestock. Rescue methods: gastric lavage, catharsis, taking a large amount of sugar water or intravenous injection of glucose saline, intramuscular injection of vitamin B1. The role of drunken fish grass ornamental application in landscaping can be used to plant grass, can also be used for slope land, wall corner greening and beautification, decorating rocks, courtyards, roads, flower beds are very beautiful, can also be used as cut flowers. Scutellaria angustifolia is resistant to cold, drought, barren, semi-shade, extensive management, waterlogging, strong plant germination, extremely resistant to pruning, without high technology. The cost of landscaping with large-leaf drunken fish grass is low. Take the greening project for example, if you plant 2000 plants with a row spacing of 50cm and 500m2, and if the seedlings raised in winter and spring are planted into the project in April, if the price is 2 yuan per plant, 500m2 will only cost 4000 yuan; if you use 60 cm high seedlings in the first year, each plant will cost 3 to 4 yuan, and 500m2 will only cost 6000 to 8000 yuan. If the row spacing is increased to 80 cm to 90 cm, the unit cost will be reduced. No matter the young seedlings of that year or the big seedlings of the first year, planted in spring, you can also enjoy the beautiful scenery from July to August. Compared with the conventional greening tree species, the cost is basically the same, but the greening effect of the big-leaf drunken fish grass is much higher than that of the conventional tree species. The cultural background of drunken fish grass plant culture the whole plant has a small poison, mashed into the river can make live fish anaesthetic, easy to catch, so it is known as "drunken fish grass". Textual Research 1. "Liuyan Materia Medica": drunken fish grass must not be planted along the edge of other people's pond. I am afraid that if the flowers and leaves fall in the water by mistake, the fish will be hurt by mistake, and its aroma will be damaged. 2. "Compendium": drunken fish grass is found everywhere in the south, mostly growing small plants on the cutting bank, and the taller ones are three or four feet high. The root is like Chinese wolfberry. The stem is like bauhinia, with micro-ribs and thin yellow bark, and the branches are easy to reproduce. Leaves are like poplars, which are born in opposite sections and are not carved in winter. July and August blossom into spikes, red and purple, like genkwa, bearing fine seeds. Fishermen pick flowers and leaves to poison fish, besieged and died, called drunken fish grass, the edge of the pond can not be planted. This flower color and smell is not the same as Wuhua, so is the poisonous fish, but the flower is different at the same time. 3. "the main poisonous plants in the south": drunken fish grass flowers and leaves, the poisoning symptoms caused by excessive consumption of human and livestock are dizziness, vomiting, dyspnea, limb numbness and tremor. Rescue methods: gastric lavage, catharsis, taking a large amount of sugar water or intravenous drip of glucose saline, intramuscular injection of vitamin B1 and symptomatic treatment. Guangzhou herbalist introduction: Fangfeng two money, licorice two money, four bowls of clear water fried to two bowls of drink; golden orchid four dollars (also known as fine leaf grass), four bowls of clear water, fried to one or two bowls to drink. The flower language of drunken fish and grass: faith. As soon as I see the person I like, I stick to it, but I get bored after a long time, so if I don't correct this behavior, I may be lonely all my life. The habit of drunken fish grass the culture method of drunk fish grass

The habit of drunken fish grass is to like warm and humid climate and deep fertile soil, strong adaptability, but not resistant to water and moisture. Drunken fish grass cultivation is easy, convenient management, no matter group planting or scattered planting, can form a better natural landscape. Next, let's take a look at the culture methods of drunken fish grass and other related knowledge.

The flowering period is from April to October, and the fruiting period is from August to April of the following year.

Cultivation method of buddleja

Buddleja buddleja branches and leaves whirling, luxuriant flowers, elegant fragrance, suitable for planting on slopes, bridgeheads, walls, or for medium-sized hedges, or grassland cluster planting, dense planting for hedges, flower belts.

1. Cultivation method

Sowing, cuttage or propagation. Because the seed is small, suitable for high bed broadcast, pay attention to moisture and shade, wait for seedlings up to 10 cm or so when the cultivation is large.

The cuttage of buddleja can be carried out in spring, with dormant branches as cuttings. It is easy to survive when the ramets are combined with transplantation. In cultivation, the aboveground part can be cut off during the dormant period to facilitate the next year to shoot new branches and bloom more flowers.

II. Reproductive methods

Buddleja adaptability, soil barren resistance, saline-alkali resistance: the soil requirements are not strict, in the soil permeability is better loam, sandy loam, gravel soil and other good growth.

The annual growth can still reach 33 cm when the soil organic matter content is above 0.3%. pH value below 9, salt content below 0.3% can grow and bloom normally. Strong resistance, cold and heat resistance, water saving and drought tolerance: in the case of temperatures as high as 40℃ and-15 ℃, it can grow normally, safely overwinter, and can withstand low temperatures of-30℃. The temporary wilting coefficient of leaves of Buddleja alternifolia is 1.292%. It is very drought tolerant. It can grow and bloom when irrigated 3 to 4 times a year in the area with annual precipitation of 180~400 mm and 1 to 2 times a year in the area with annual precipitation of 400 mm. It is a good ornamental plant with water saving and drought resistance.

Buddleja xuejinze for the light branches tough and strong, and vigorous growth, flower vigor flourishing, colorful, resistant to pruning, suitable for modeling, ornamental strong: through reasonable pruning of Buddleja alternifolia not only compact plant type, long flowering period, can be used in isolation, hedge planting, belt planting, sheet planting and other ways, a large area of parks, street green and both sides of the highway, resulting in a momentum of beauty.

Buddleja is easy to propagate, cultivation management is simple and extensive: Buddleja can be seeded, cuttings, tissue culture propagation, especially young cuttings propagation easy to survive, after 2 to 3 years of flowering, effective quickly.

Extensive management during the growth period, no winter protection measures such as cold; fewer diseases and insect pests, can reduce the cost of prevention and control and environmental pollution; strong branches, pruning resistance, generally suitable for pruning after flowering; minimal fertilization, application of decomposed base fertilizer before planting.

The reproduction method of Buddleja

1. Breeding methods

It is better to use twigs cutting in May and June growing season. High survival rate, fast growth, rapid reproduction.

Before cuttage, set up a shade shed, disinfect the river sand in the cutting bed with potassium permanganate or carbendazim, cut the semi-lignified branches into a section of 10 cm long, remove all the lower leaves, and cut two thirds of the upper 2~3 leaves. Upper shear 1 cm flat from bud, lower shear obliquely horseshoe-shaped on back of bud.

Cut a groove 5 cm deep in the river sand with wood chips, place the cuttings dipped in rooting agent neatly, cover them with sand, pat them and spray water. Cutting density to leaves do not contact, uniform distribution is appropriate, to be inserted after the entire plot is complete, then spray a permeable water, and then set up an arch shed covered with plastic film, closed around.

Before rooting, spray water twice a day to cool down and keep moisture, keep the temperature in the shed at about 28℃ and the relative humidity above 90%. Rooting takes place about 20 days in May and June, and 2 weeks in July and August. Control moisture after rooting, pay attention to ventilation, and remove arch shed according to rooting situation. Transplant seedlings after a week of tempering.

2. Planting

After rooting with cuttage seedlings bare root transplant, nursery must be intensive cultivation. In order to prevent the occurrence of diseases and insect pests, phoxim granules of 3 kg ~4 kg and ferrous sulfate of 50 kg were applied per mu when the nursery was tidied up. When transplanting, follow a "fast" word, fast planting, planting a plot quickly irrigation. Due to the rapid growth of Buddleja, plant spacing should not be too small, 35 cm ×50 cm is appropriate. After transplanting, cover the seedlings with sunshade net for 2~3 days directly, remove the sunshade net in the afternoon after 3 days and irrigate them again with permeable water. When the surface of the ground is slightly dry, hoe them lightly to preserve moisture. After 7~10 days of transplanting seedlings can survive, 2 months later a colorful scenery will appear in front of you.
