Main points of propagation of vine peanut

The growth of vine peanut is strong, the requirement of growth environment is not high, and it can grow well in full sunshine and half-day sunshine. Vine peanut has strong resistance to harmful gases, so it is very suitable to be used in garden.

Vine peanut

Vine peanuts can be propagated by sowing and cutting. because of the laborious seed harvesting, cuttings are used in a large number of propagation. Cuttings can be carried out in spring, summer and autumn, generally in rainy season or cloudy days, and it is better to make cuttings in the middle section, which can promote its early rooting, more branches and proper fertilization to promote its growth after turning green.

Classification of jasmine cultivation methods of jasmine

Jasmine flower is a kind of indoor plant flower which is deeply loved by all of us. It has white color and fresh and elegant fragrance. So what are the categories of jasmine and how should we breed them? Today I will tell you about the classification of jasmine and the method of cultivating jasmine.

Classification of jasmine flowers

1. Single jasmine

Single jasmine plant is relatively short, 70cm to 90cm high, with thin stems and branches, showing a vine type, so it is known as "Fujimoto jasmine".

The leaf is oval, the leaf quality is thin, the leaf tip is slightly pointed, the entire margin, length 5-9 cm, width 3.5-5.5 cm. Corolla monolayer, lobes (petals) less, 7 to 11, each about 1.3 cm long, 1 cm wide, oval, white, slightly wrinkled surface, tip slightly pointed, so it is also called pointed jasmine.

Single jasmine Corolla tube longer, about 1.5 cm, 2 stamens, as long as pistil. Inflorescences clustered and scattered, terminal or axillary, each inflorescence bearing 3-12 flowers, up to more than 30. The buds are slightly longer, smaller and lighter. The single-valve jasmine in China has been selected and bred for many years, and more local improved varieties have been formed. the ones with high yield and good quality include Fujian Changle, Fuzhou, Jinhua and Taiwan. Among them, Taiwan jasmine is refreshing, fresh and pure.

The bud of single-petal jasmine blooms early, and the summer flower usually opens at 6-7 o'clock in the evening, which is heavy per 100 flowers, about 22-25 grams per hundred flowers, which is lighter than double-petal jasmine. The jasmine tea scented with single jasmine has a rich aroma and fresh taste, which is inferior to that of double jasmine.

Single jasmine has strong drought tolerance and is suitable for planting on hilly and hilly slopes, but its flower yield is less than double jasmine, 150,200kg per 0.067 ha, no more than 400kg high, and it is not resistant to cold, waterlogging and weak resistance to diseases and insect pests.

2. Double jasmine

Double jasmine is the main variety cultivated in a large area in China. The plant is 1-1.5 meters high, it is an erect tufted shrub with many branches, the stem branches are thick and hard, and the basal epidermis of the stem has grayish brown wrinkles.

Young stems green, sturdy branches angled and shortly hairy. Leaves opposite, broadly ovate, entire, reticulate veined, thick green, thick and glossy. Cymes, terminal or axillary, each inflorescence bearing 3-17 buds, up to more than 30.

The buds are oval, flat or slightly pointed at the top, also known as flat-headed jasmine. Double-petal jasmine is usually of better quality with a pointed tip, and the flowers are fatter and have slightly lower water content than single-petal jasmine. Corolla tube is slightly shorter than single jasmine, about 1 cm long. Corolla lobes (petals) are more, 13-18, the base is imbricate and arranged into two layers, the inner layer is 4-8, and the outer layer is 7-10. The petals are about 1.1 cm long and 1 cm wide. There are 2 stamens and 1 pistil.

The flowers are white and pure, the wax is obvious, the fragrance of the flowers is strong, and the fragrance is late and slow. The opening time of flower buds is about 2 hours later than that of single jasmine, and the flowers generally open at about 8 ~ 9 o'clock in the evening, and natural fragrance can be delayed for more than ten hours. Each hundred flowers weigh about 23 grams of spring flowers, 30 grams of summer flowers and 26 grams of autumn flowers. The scented tea made with double jasmine has a mellow and strong aroma, which is not as fresh and pure as single jasmine tea, but double jasmine has tough branches, strong stress resistance, cold resistance, moisture tolerance, easy cultivation and high yield per unit area. at present, double jasmine is mainly planted in various parts of our country.

When planted in Hengxian County, Guangxi, the yield of fresh flowers can reach 150,200kg per 0.067 ha, about 500kg per 0.067 ha in three years, and 800kg / 1000kg per 0.067 ha for more than five years. The highest yield can reach more than 1500 kg.

3. Multi-valve jasmine

The branches of multi-petal jasmine have obvious verrucous protuberances. The leaves are dark green, the buds are tight, round and short, and the top is slightly notched.

Corolla lobes (petals) small and thick, and especially many, generally 16-21, the base is imbricate and arranged into 3-4 layers, with distinct layers when opening. There are 2 and 3 stamens. Most of the multi-petal jasmine flowers bloom at 7-8 o'clock in the evening, and most of them open 1-2 layers first, and the rest are finished the next day.

There are also those who wither when they are not open. The opening time of multi-petal jasmine is very long, the aroma is lighter and the yield is less, so the flowers used as scenting scented tea are not ideal. However, it has strong drought tolerance and strong growth in hillside dryland. Through cross breeding (or grafting) with excellent single or double jasmine varieties, it is likely to obtain a new jasmine variety (new jasmine) with strong resistance, good quality and high yield.

Culture methods of jasmine flowers

Reproduction method

1. Cuttage propagation

From April to October, mature 1-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 40-60 days.

2. Striping propagation

Select longer branches, gently cut in the lower part of the node, buried in a small basin filled with sand and mud, often moisturize, begin to take root in 20-30 days, and can be cut off from the mother plant after 2 months and planted separately.

Key points of culture

1. Environment and lighting:

Jasmine is fond of hot, humid, ventilated and breathable environment and needs 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 6 to 6.5, the root system is dense and the growth is vigorous, such as viscous weight of soil, lack of matrix, low fertility, poor ventilation, less root system, short plant, slender stems and leaves, and few flowers.

4. Fertilization:

The high temperature season in midsummer is the peak period for the growth of jasmine, applying more organic fertilizer and phosphorus and potassium fertilizer, such as peanut cake powder, bone powder, calcium superphosphate and multi-element flower fertilizer, twice a month. Jasmine often has luxuriant branches and leaves but does not blossom in summer, the main reason is that too much nitrogen fertilizer is applied, resulting in the growth of branches and leaves. In such a situation, it is necessary to control fertilizer and water, increase the application of phosphorus and potassium fertilizer, and promote the gestation of flower buds. At the same time, we should pay attention to move the jasmine to a place with sufficient sunshine and good ventilation.

5. Pruning:

Jasmine grows very fast in summer, should be pruned in time, potted jasmine pruning to retain the base 10 cm to 15 cm, promote most sturdy new shoots, if the new shoots are very prosperous, they should pick the heart when growing 10 cm, promote secondary shoots, then bloom more, and the plant shape is compact. After the flower withered, the flower branches should be cut off in time to reduce the consumption of nutrients, but also promote the growth of new shoots, so that the branches are dense, buds are more, and flowers are more.

6. Control of diseases and insect pests:

Jasmine is often harmed by borer larvae and shell insects and red spiders, which is the most serious from July to September. It often eats buds and can be sprayed with almighty powder or permethrin plus water 200 times every semimonthly, that is, no diseases and insect pests should be sprayed in advance, and the spraying time is 9: 00 a.m. and 4: 00 p.m. on a sunny day, and should not be sprayed in the hot sun at noon to prevent drug damage.

Culture method of Eurasian Huoxue Dan

Culture method of Eurasian Huoxue Dan

Basic data of Eurasian Huoxue Dan

Scientific name: Glechoma hederacea

Families and genera: Labiatae, Huoxuedan genus (also known as Artemisia).

Perennial evergreen creeping herb, about 15 cm tall. Stem slender, 1-2 m long, square, finely pilose. Leaves opposite, reniform or cordate, 2 × 4 cm wide, margin crenate, light green, pubescent, long stalked. Flowering from May to June, peanuts in leaf axils, small flowers, Corolla light blue, rarely white, lower lip with dark spots.

Eurasian Huoxue Dan hanging under its branches and leaves, shaped like a waterfall, especially flowers and leaves, its green leaves are inlaid with white or yellowish markings; the leaves are rubbed to give off fragrance, giving people a fresh, relaxed and elegant feeling; strong adaptability, rapid growth and easy reproduction. Suitable for ground cover plants under sparse plants; can also be potted to place several shelves, cabinets and other high places or for hanging decoration.

[Eurasian Huoxue Dan varieties and flowers of the same genus]

⑴ mosaic Eurasian Huoxue Dan (cv. Variegata): also known as Caiye Lianqiancao, Caiye Huoxue Dan, Flower Leaf money mint, White spot Eurasian Huoxue Dan. It is a cultivated horticultural species of Eurasian Huoxue Dan. The margin of the leaf is light green with white or yellowish patches and becomes reddish in winter.

(2) even money grass (G. longituba): also known as Huoxue Dan, money grass, Chuandi incense, incense everywhere. Perennial herb, 30 cm tall. Stem creeping, quadrangular. Leaves opposite, cordate or reniform, hairy on both surfaces. Summer flowering, verticillate inflorescences, with 2-6 flowers, lip-shaped, lavender to pink. Nutlets, oblong-ovate, brown.

[Eurasian Huoxue Dan propagation] ramet, cuttage, striping.

(1) ramet: in spring or autumn. Cut off the branches with adventitious roots and plant them directly in the pot.

(2) cutting: cutting can be carried out at any time when the temperature in the growing season is above 15 °C, mainly from May to June. Cutting the stem vine with a length of 15 cm to 20 cm for cuttings, because the branches have the characteristics of nodal rooting, so the cuttage survival rate is very high, and it can take root and survive about 1 week after cutting. The cut branches can also be inserted with water, and it takes 2 to 3 weeks to take root, which is very easy to survive.

(3) striping: it is also carried out during growth. The 1 ~ 2 nodes of the branches and vines are buried in a basin, and the covered soil is 2 ~ 3 cm thick, so it is easy to take root, and it can be cut off from the mother plant when taking root.

[main points of planting Eurasian Huoxue Dan]

(1) temperature: like warmth, and the optimum temperature for growth is 15-28 °C. More hardy, can endure the low temperature of-KTC in winter. When cultivated in open field, the leaves turn red slightly after frost in winter. If the ground part dies at a low temperature after winter, it will branch and grow again when the weather turns warm in the spring of the following year. If you move indoors before winter, you can keep the four seasons green.

(2) Illumination: like semi-overcast environment, afraid of strong light. Shading should be carried out when the high temperature and strong light in summer, covering 30% to 40% of the light.

(3) watering: like the moist soil environment, can not bear thousands of drought. During the growth period should be fully watered, keep the basin soil moist, do not wait for the basin soil to dry before watering. When the basin soil is too dry, the stems and leaves are easy to wilt. Reduce watering in winter and keep it a little moist.

(4) Environmental humidity: like a humid environment, you should often spray water to the branches and leaves and around them when growing, so as to increase the relative humidity of the air. But do not spray water to the blade at high temperature, otherwise focal spots are easy to appear on the leaf surface.

(5) fertilization: fertilization is applied once a month in the growing season, and attention should be paid to the combination of nitrogen, phosphorus and potassium. In order to avoid excessive growth of branches, it is necessary to control the application of nitrogen fertilizer. Stop topdressing fertilizer in winter.

(6) pruning: pruning the plant once in spring combined with turning the basin, cutting off the aged branches and cutting the overlong branches.

(7) upper pot and turning pot: plant flowerpots with a diameter of 15 cm and 20 cm, with 5 plants per pot. The matrix can be prepared with rotten leaf soil, garden soil and rice chaff ash or coarse sand for sandy loam with good fertility and good drainage. The pot should be turned every spring when the root system is full.

(8) Prevention and control of diseases and insect pests: downy mildew is easy to occur in the rainy season, and other pests such as red spiders, thrips, whitefly and slugs are harmful.

[common problems in Eurasian Huoxue Dan cultivation]

The causes of common problems are: excessive growth of branches and ① fertilizer and water; poor light of ②, wilting of branches and leaves, low temperature of ① at the focal edge of leaves, too strong light of ②, too dry air of ⑤, and long-term failure of ④.
