The latest breeding methods of lavender

Lavender is a kind of flower that everyone likes more, the home that decorates with lavender is romantic and have mood, and still be a kind of flower with very wide use, believe everybody hopes to plant a few pots inside the home, breed basically to have sow, cuttage, layering, cent root to wait for a method, adopt cuttage propagation mainly in production, below we take a look at lavender breed method together!

Lavender ramet propagation

Lavender ramet propagation can be carried out in spring and autumn, with 3-4-year-old plants, in spring 3-4 months with adult plants old roots division, each branch with bud eyes.

Lavender seed propagation

1. Seed collection: Lavender blossoms in April, and can be harvested after seeds mature in June and July. After picking lavender spikes, spread them indoors or in a greenhouse with film. Don't stack them too thick. Dry them naturally. After about 10 days, wait for pedicels and exocarp to lose water and become crisp. Rub them and blow them again. You can separate nuts from impurities. French lavender nuts need to be further air-dried. When its water content drops to 12-15%, you can put them away and put them in ventilation. Set aside in the shade.

2, sowing method: lavender suitable for spring sowing (3-5 months) and autumn sowing (9-10 months), sowing with special sowing medium is better, can also be prepared with peat plus a small amount of pearlite, the medium installed in the seedling plate, drive flat, spray a small amount of water to wet the sowing, drilling or broadcasting can be, about 10 seeds per square decimeter, after sowing, cover a thin layer of coconut bran or vermiculite, spray water again, depending on the medium dry and wet and then appropriate water spray.

3, after sowing management: lavender seeds after sowing, about a week can be unearthed, its seedling disease resistance is very strong, unearthed can be sprayed 800 times every two weeks carbendazim disease prevention, need a certain amount of light and nutrients, otherwise easy to grow, the formation of slender seedlings, lavender can be transplanted once when growing to 4-6 true leaves, to facilitate the distribution of lateral branches, autumn seedlings can be planted in spring, spring seedlings can be planted 50-60 days later.

Lavender cutting propagation

1, cuttage period: Lavender has strong adaptability to cuttage propagation, can be propagated in spring and autumn, even in summer, the use of softwood cuttage is feasible, but the conditions are more strict, humidity is small and easy to wilt, humidity is large and easy to stem rot, from the production point of view, generally in the autumn when the local temperature drops to 15-25℃ for cuttage.

2. Cutting treatment: The quality of cuttings has a direct impact on the survival rate of cuttings. Cuttings should be selected from healthy plants with short and thick annual semi-lignified branches without heading. The cuttings should be cut at the top 8-10 cm. The cut of cuttings should be close to 0.5-1 cm below the stem node. The cut should be smooth, and the lower two-thirds of the leaves should be removed. Do not break the phloem.

3, cuttage method: cuttage medium with pearlite and peat each half of the mixed medium is the best, conditional nursery can be done in the greenhouse cuttage bed cuttage, poor conditions can be done in the field cuttage bed, cuttage after the arch pole cover film, cuttage bed generally 1.5 meters wide, length according to the site. Medium spread about 15 cm thick, pay attention to disinfection before use, insert 5-8 cm deep, plant spacing 3-4 cm, row spacing 5-6 cm, pour water immediately after insertion, cover with film to keep moisture.

4, after cutting management: lavender cutting humidity appropriate, improve the ground temperature, can promote the root system developed, improve the seedling rate, more than 10 days after cutting will take root, more sensitive to water, slightly dry is appropriate, two months later can be on the nutrition bowl or transplant, promote the sound development of the root system, increase branches, cultivate strong seedlings.
