Cultivation method of jasmine in pot

The main results are as follows: (1) according to the characteristics of good permeability and humid environment of jasmine root system, pot jasmine should be planted in plain mud basin, glaze basin, porcelain basin and so on. There are generally three specifications of plain burning mud basin suitable for planting jasmine: caliber 25cm with a height of 15cm, caliber 30cm with a height of 17cm, and caliber 36cm with a high 22cm. The diameter of the flowerpot is slightly smaller than that of the tree crown, which is beneficial to maintain the humidity of the pot soil.

(2) the culture soil was prepared with 4 parts of loam, 4 parts of compost and 2 parts of sand, plus a small amount of bone powder, cake fertilizer, plant ash and so on. It is required that the cultivated soil is fertile, loose, strong in water and fertility conservation and good in permeability. Rotten garbage can be sifted through 16 holes instead of sand and disinfected with formalin. Sprinkle 1.5% formalin 2L evenly in 100m ³soil, then cover with grass or mat and use it after 48 hours.

(3) after covering the drainage outlet with tiles or broken plates, add 3cm thick coarse culture soil or coarse sand or cinder, and then use the prepared culture soil for planting. When planting, wash the roots of the seedlings first, and cut off the main roots, overlong lateral roots and injured roots. Cut and set the stem at the 15~20cm of the root neck, and then divide the 4-6 seedlings into 2 or 3 clumps and plant them in the basin.

(4) when the jasmine flowers planted in the pot grow from small to small, and the root system is all over the whole basin, the plant needs to change from the small pot to the large pot. Generally, before the jasmine sprouts, the root system is pruned and then a larger basin is replaced.

(5) when the management does not change the basin, the old soil with 2em thickness can be removed from the surface, and then the new culture soil can be added.

Fertilization: the principle of fertilization for potted jasmine is to apply thinly and diligently. Topdressing with bone meal, human and animal manure and urine oil retting to produce mature fermented fertilizer and water, urea and compound flower fertilizer as the auxiliary.

During the germination of new buds, the above-mentioned retting and rotten fertilizers with a concentration of 5% were applied every other day, and 100 g urea and compound fertilizer were added to 25kg every 3-4 days. In the flowering season, fertilizer should be applied every 2-3 days, and the ratio of fertilizer to water is 4:8 or 3-7.

Watering: potted jasmine still holds the principle that the pot soil is not dry or irrigated. When the temperature is low in spring and autumn, it should be watered every 2 or 3 days, and once every 1-2 days in summer. The "three volts" day from June to August, high temperature and drought, large amount of water evaporation, irrigated once a day in the morning and afternoon. From November onwards, the water supply should be strictly controlled throughout the winter.

In the flowering period, the amount of water should not be too much, especially the jasmine used to watch flowers should control the water content and prolong the flowering period.

Shaping and pruning: the same as open-field cultivation, as long as careful cultivation, proper soil, fertilizer and water conditioning, timely heart-picking, shoot-cutting and leaf-picking, paying attention to pest control and strengthening cold protection and heat preservation, a bumper harvest of potted jasmine can be obtained.

Pot cultivation method of jasmine cultivation method of family culture of jasmine

There are always some colors to fill in. Big or small, a rain, at the top of the earth. After April, it will be the sound of the waves. The wind rattled into my ears, and so quickly, the sun walked around the tree and brought in a group of leaves. And birdsong. Birds chirping in the warm breeze, streets reflected above the streets, songs sung in songs. Above the earth. A kind of listening, seize the sun and the wind, seize the power of the years. So, do you know anything about jasmine? Next, the editor will introduce jasmine to you.

(1) selecting basin

According to the characteristics of the root system of jasmine, which requires good permeability and humid environment, potted jasmine should be planted in plain mud basin, glaze basin, porcelain basin and so on. There are generally three specifications of plain burning mud basin suitable for planting jasmine: caliber 25cm with a height of 15cm, caliber 30cm with a height of 17cm, and caliber 36cm with a high 22cm. The diameter of the flowerpot is slightly smaller than that of the tree crown, which is beneficial to maintain the humidity of the pot soil.

(2) preparation of cultivated soil

It was made of 4 parts of loam, 4 parts of compost and 2 parts of sand, plus a small amount of bone powder, cake fertilizer, plant ash and so on. It is required that the cultivated soil is fertile, loose, strong in water and fertility conservation and good in permeability. Rotten garbage can be sifted through 16 holes instead of sand and disinfected with formalin. Sprinkle 1.5% formalin 2L evenly in lOOm3 soil, then cover it with grass or mat and use it after 48 hours.

(3) upper basin

First cover the drain with tiles or broken pots, add 3cm thick coarse culture soil or coarse sand or cinder, and then plant with the prepared culture soil. When planting, wash the roots of the seedlings first, and cut off the main roots, overlong lateral roots and injured roots. Cut and set the stem at the 15~20cm of the root neck, and then divide the 4-6 seedlings into 2 or 3 clumps and plant them in the basin.

(4) change the basin

When the jasmine flowers planted in the basin grow up from small to small, and the roots cover the whole basin, the plant needs to change from the small pot to the big one. Generally, before the jasmine sprouts, the root system is pruned and then a larger basin is replaced.

(5) Management

When the basin is not changed, the old soil with 2cm thickness can be removed from the surface and the new culture soil can be added.

Fertilization:

The principle of fertilization for potted jasmine is to apply thinly and diligently. Topdressing with bone meal, human and animal manure and urine oil retting to produce mature fermented fertilizer and water, urea and compound flower fertilizer as the auxiliary. During the germination of new buds, the above retting rotten fertilizers with a concentration of 5% were applied every other day, and 1009 urea and 1009 compound fertilizer were added to 25kg every 3 to 4 days. In the flowering season, fertilizer should be applied every 2-3 days, and the ratio of fertilizer to water is 4:8 or 3:7.

Watering:

Potted jasmine still holds the principle of no drying and no watering of potted soil.

Pot culture methods and matters needing attention of jasmine

Jasmine flowers like to be warm and humid and grow best in a well-ventilated and semi-overcast environment. The soil is the most suitable for slightly acidic sandy soil which contains a lot of humus. Most varieties are afraid of cold and drought, and are not resistant to frost, waterlogging and alkaline soil. When the winter temperature is lower than 3 ℃, the branches and leaves are easy to suffer frost damage, and if they last for a long time, they will die.

Culture environment of jasmine

1. Lighting: Jasmine is fond of inflammation, heat, humidity, ventilation and breathable environment, which requires sufficient light. Jasmine is afraid of the cold. Potted jasmine in the south can be cultivated outdoors to survive the winter. In the north, it is necessary to keep warm in autumn and winter, and move indoors and put it toward the south. If the light is strong, the branches are strong, the leaves are dark green, the flowers are many and fragrant, and if the sun is not enough, the flowers are sparse and not fragrant.

2, moisture: Jasmine is not resistant to drought, but avoid stagnant water, rainy season should be timely dumping stagnant water in the basin, otherwise the leaves are easy to yellowing. In summer, hot and sunny days should be watered twice a day, once in the morning and evening, if you find that the leaves curl and droop should spray water on the leaves to promote growth.

3. Soil: it is better to cultivate jasmine in fertile sandy and semi-sandy soil. When planted in slightly acidic soil with pH value from 6 to 6.5, the root system is dense, the growth is vigorous, such as clay weight, lack of matrix, low fertility, poor ventilation, less root system, short plants, slender stems and leaves, and few flowers.

The propagation mode of jasmine

Jasmine multipurpose cuttings can also be pressed or ramets.

1. Cuttage propagation: from April to October, mature one-year-old branches were selected, cut into cuttings with more than two nodes, removed the lower leaves, inserted in the bed with half of the sediment, covered with plastic film, maintained high air humidity, and rooting in about 40 to 60 days.

2. Striping propagation: select longer branches, gently cut at the lower part of the node, bury them in a small basin containing sand and mud, often moisturize, and begin to take root in 20-30 days. After 2 months, they can be cut off from the mother plant and planted separately.

Planting methods of jasmine flowers

In midsummer, it is necessary to water early and late every day, such as dry air, need supplementary spraying; during winter dormancy, it is necessary to control the amount of watering, such as basin soil is too wet, it will cause rotten roots or fallen leaves. During the growth period, thin cake fertilizer should be applied once a week. After changing pots in spring, you should often pick the heart for plastic surgery, and re-cut it after flowering to facilitate the germination of new branches, so that the plant is neat and robust and blossoms vigorously.

Fertilization method of Jasmine Flower

From June to September, liquid fertilizer containing more phosphorus is frequently applied, preferably every 2-3 days. Fertilizer can be made of mature bean cake and fishy water fertilizer liquid, or ammonium sulfate and calcium superphosphate. In general, more chemical fertilizer ingredients will burn jasmine plants. 0.1% potassium dihydrogen phosphate aqueous solution can also be used to spray the foliar surface in the evening, or it can promote more flowering.

Flowering maintenance of Jasmine Flower

Jasmine likes fertilizer very much, and potted jasmine can blossom three times a year as long as it is properly maintained. If there is not enough fertilizer and nutrients, after blooming once, it will no longer blossom. If the management is in place, it can be opened continuously from the end of May to the beginning of November. The key is the mastery of pruning, sunshine, and water.

Jasmine has blossomed one after another since early summer. If properly managed, there can be three periods of blooming.

In early June, jasmine blossoms one after another, and the method of picking flowers is to pick the twigs with leaves to promote the re-emergence of new branches and luxuriant branches and leaves. At this time, apply light fertilizer and water twice a week, and keep the basin soil moist.

The first flowering period is from late June to early July, when it is necessary to strengthen the management of fertilizer and water, apply thin fertilizer frequently, fertilize once every 2 days, and apply fully mature organic liquid fertilizer, the ratio of fertilizer to water is 1:4. Watering should be adequate, usually once a day. Usually watering should be carried out in the morning, while fertilization should be carried out in the evening. This lasts until late July, because there is plenty of fertilizer and water, which can make the flowers bloom bigger and more.

In the first ten days of August, the second stage of flower formation, at this time fertilization should be slightly thicker than before, generally with half fertilizer and half water. In order to make jasmine blossom better, calcium superphosphate solution can also be sprayed on the leaf surface. In late August, fertilization was gradually reduced and applied once every 6-7 days, but watering was still needed and kept once every 2 days.

From early September to early October, the third stage of flower formation, at this time should stop fertilization, watering should also gradually reduce, because the weather has gradually turned cool, will affect the formation of bud, so the number of these flowers is less, to the end of flowering after the middle of October, just keep the pot soil slightly wet.

Pest control

1. Pest control

The main pests of jasmine are leaf roll moth and red spider, which damage the top tip and tender leaves, so we should pay attention to timely control. For red spiders (mites), try not to use dichlorvos and dimethoate, because the smell of these two pesticides is too strong (many days can not be dispersed, especially fumigating), and are not specific drugs for red spiders.

Biological control: removal of dead branches and leaves and concentrated watering can reduce part of the overwintering base and protect and utilize natural enemies. Predatory mites, ladybugs, lacewings and thrips all have a certain control effect on mites, so the safety of natural enemies should be considered when choosing insecticides, and if conditions exist, natural enemies can be released artificially.

Chemical control: red spiders have strong reproductive ability, strong pressure on the selection of agents, and are easy to produce drug resistance, so drugs should be used in time and rotation. The commonly used agents and concentrations are 25% triazoltin wettable powder 1000 × 2000 times, 50% bromine mite EC 2000 times, 20% formamidine EC 1000 times, 20% triclofenac 1000 times, 50% dichlorofos EC 1000 times, 40% omethoate 1000 times. Note that the above agents should not be mixed with Bordeaux liquid and other alkaline pesticides.

2. White silk disease

Symptoms: mostly occurred at the base of the stem. The susceptible plants became brown and rotten, the skin of the diseased part was easy to peel off, and white sericeous hyphae were produced on the surface. In the later stage, rapeseed-like sclerotia appeared in the disease. The pathogen overwinters with sclerotia or mycelium in the soil or on the disease residue. Rain Water is prone to repeated infection when there are many times from May to June and August to September every year.

① removed the remains of diseased plants in time and destroyed them centrally.

② should strengthen management, strict quarantine and put an end to the source of disease.

At the beginning of ③ disease, the surrounding soil was disinfected with 70% pentachloronitrobenzene, or sprayed with 1% Bordeaux solution or 0.3 Baumedu stone sulfur mixture, or 50% wettable antiseptic soil for prevention and treatment. When the disease is serious, spray 75% chlorothalonil wettable powder 800-1000 times liquid, or 65% Dessen zinc wettable powder 800 times liquid.

④ uses 82 Trichoderma bran biological preparation, mixed with fine soil, mixed in the basin soil.

3. Anthrax

Symptoms: mainly harm leaves, sometimes also harm tender shoots. At the beginning of the disease, there are small light green to yellow spots on the leaf surface, and gradually expand into grayish brown or gray-white round or near-round spots. Black dots are scattered on the plaque in the later stage. The pathogen overwintered on the damaged leaves with conidia and mycelium. Generally, the disease is more serious in summer and autumn.

① should strengthen the cultivation management, remove and destroy the diseased leaves in time.

② disease is sprayed 2 times 3 times, 70%, 600 times, 800 times, and once every 10 days. 0.1% liter of mercury solution or purple potion can also be applied in the family.

When the disease of ③ is serious, spray 50% thiophanate or 75% chlorothalonil wettable powder 800-1000 times, or 50% carbendazim 1000 times, 65% Dysen zinc 500 times.

4. Leaf spot

Symptoms: most of them occur in the leaves. At the beginning of the disease, brown spots were produced on the leaves, which gradually expanded into round or irregular shapes, the disease became thinner, brown and transparent, and black particles appeared on the spots. Pathogens overwintered on diseased leaves by mycelium or conidia. It usually occurs from May to June, and the peak period is from July to August.

The diseased leaves were cut off and destroyed by ① in time.

② applied less nitrogen fertilizer and more phosphorus and potassium fertilizer.

③ disease is initially sprayed with 70% Rocco 600k800 times, once every 10 days, or 65% Dyson zinc 600,800 times, or 1% equivalent Bordeaux solution of 1 ∶ and 1 ∶.

5. Soot disease

Symptoms: dark brown mildew spots appeared on the leaves at the beginning of the disease, which gradually expanded to form a black soot-like mildew layer. The disease is caused by bacterial breeding caused by the excrement of aphids and shell insects.

① strengthens management and improves ventilation conditions.

② eliminates aphids and scale insects in time.

Spray 160x equivalent Bordeaux solution before the onset of ③; at the beginning of the disease, spray 50% carbendazim wettable powder 800-1000 times.
