Points for attention in planting lavender in a large area

Lavender is a vanilla plant that many people are very familiar with. Because of its extensive management and low difficulty in cultivation, lavender is also loved by many flower friends. But planting lavender in a large area still needs to pay attention to a lot of problems, how to improve the budding rate, how to manage the seedling stage, the editor will introduce it to you.

Lavender

1. The flat ground is watered thoroughly, and the soil with good drainage is selected. the size of the flat field can be determined according to the number of seeds, and the sown area per kilogram of seeds is about 100 square meters. Then fully water the field border and add an appropriate amount of caprylic acid to prevent insect pests.

2. Seed treatment, in order to improve the germination rate of lavender seeds, soak lavender seeds before sowing, soak in clean water for 12 hours, and then soak with gibberellin for 6 hours. Gibberellin should be dissolved with high alcohol or alcohol, the ratio of gibberellin to 4 jin of water per gram.

3. Sow and cover the soil. In order to sow the seeds evenly, we can mix the seeds with a pot of fine soil and then sow them. Then cover the soil, covering the soil evenly, with the seed size of 2MUR 3 times thicker.

4, heat preservation, cover the whole field with plastic film to keep moisture, cover the sunshade net to prevent direct light, the temperature of the eighth and ninth months of the lunar calendar is about 20 °, 5Mel can emerge in 6 days, and 7Mel 8 days seedlings can basically emerge.

5, refining seedling management, after the lavender seedlings come out, we remove the plastic film and the sunshade net, while spraying fungicides to prevent rotten seedlings, generally use a bag of chlorphenicol with 15 kilograms of water, three times at intervals of five days.

Management method of sowing lavender in large area

China Garden Network, Oct. 10: purple and romantic lavender, as a kind of vanilla plant, is loved by people because of its extensive management and easy cultivation. Lavender manors, lavender flower sea landscape and large area lavender planting bases continue to emerge in our country, so how to improve the sprouting rate of lavender sowing in a large area and how to manage it at seedling stage? let's introduce the sowing and management methods of lavender:

1. The flat ground is watered thoroughly, and the soil with good drainage is selected. the size of the flat field can be determined according to the number of seeds, and the sown area per kilogram of seeds is about 100 square meters.

3. Sow and cover the soil. In order to sow the seeds evenly, we can mix the seeds with a pot of fine soil and then sow them. Then cover the soil, cover the soil evenly, 2-3 times the thickness of the seed size.

4. Keep warm, cover the whole field with plastic film and cover the sunshade net to prevent direct light. The temperature of the eighth and ninth months of the lunar calendar is about 20 °. The seedlings can emerge in 5-6 days, and the seedlings will basically emerge in 7-8 days.

5, refining seedling management, after the lavender seedlings come out, we remove the plastic film and the sunshade net, while spraying fungicides to prevent rotten seedlings, generally use a bag of chlorphenicol with 15 kilograms of water, three times at intervals of five days.

When the seedlings grow up to 10 centimeters or so, they can be transplanted. The above lavender sowing method is a summary of many years' experience and can be used as a reference for large-scale sowing.

How to grow lavender (for several months) planting methods and matters needing attention of lavender

When it comes to lavender, many people must have a feeling of happiness, purple petals make people feel romantic and beautiful. The reason why lavender is so popular now is inseparable from its appearance. Lavender is of high value, it can also be eaten and beautified, so now many people grow it in ivory.

How to grow lavender (for several months)

Lavender can be cultivated by sowing or cutting. Sowing can be carried out in spring (March-June) or autumn (September-November) every year, and the germination days are about 15 days. If you buy a potted plant from a florist, you can also cut and plant it by yourself. you can choose the top bud (about 5 ~ 10), remove the leaves from the bottom 2 nodes, and then cut them in the soil after 2 hours of water. it will take root in about 2 or 3 weeks. The cutting medium can be mixed with the coarse sand of 2 stroke 3 and the peat moss of 1 stroke 3.

Planting method of lavender

1, sowing method: generally larger seeds (such as lavender, sage), you can order 2-3 seeds in each container. After germination, depending on the growth status of the seedlings, leave a stronger one, and the seeds are small (such as Mayoram). Sow some seeds with your hands, sow them gently on the soil, and plant seedlings after germination. Leave 1-3 seedlings as appropriate.

2. Seed covering soil: the thickness of seed covering soil depends on the seed size, which is generally 2 to 3 times the seed diameter, the fine seed soil is thinner, lavender seeds can be thicker, and some seeds have strong phototaxis. Can not cover the soil (such as vanilla, Rosemary).

3. Watering: lavender does not like the retention of water in the roots. After one-time watering, the soil should be fed again when the soil is dry. The surface culture medium is dry, the interior is moist, and the leaves wilt slightly. Water in the morning, avoid the sun, do not splash water on leaves and flowers, otherwise it is perishable and breeds diseases and insect pests. A continuous humid environment will cause the roots not to breathe enough air and grow poorly, or even suddenly die of the whole plant, which is often the reason for the failure of lavender cultivation.

Matters needing attention in planting lavender

The main results are as follows: 1. the newly planted seedlings and perennial seedlings will be plucked and released at the end of May next year, and watered when the temperature rises, so as to determine the roots of the young seedlings and pour the key water for the old seedlings to return to green. After a week of watering, loosen the soil, preserve soil moisture and increase temperature. In the old seedling field, 19kg of urea, 15kg of calcium superphosphate and 30kg of oil residue were applied to the old seedling field. In order to play the role of fertilization, loosening the soil, preserving soil moisture and raising temperature, it is conducive to the green growth of lavender in spring.

2. Newly planted seedling plots should be well watered, watered 4 or 5 times a year, and ploughed and weeded in time. The flower buds appeared before June 20 should be knocked out in time to promote multiple branches of the plant, so as to lay a foundation for the formation of yield in autumn and high yield in the coming year. For the old seedling plot, there should be no weeds in the field, and the budding water should be watered in early May and the flowering period in June.

Prevention and Control of Diseases and insect pests of Lavender

1. Lavender leaf spot: the main prevention and control method is to spray Bordeaux solution 1V200 to prevent 2x 3 times, or Dyson zinc 500 times 800 times. Red spider

2. Red spider of lavender: its control methods mainly include timely treatment of dead branches and leaves, cleaning up the environment to destroy the living place of spider mites, correct farming methods, reasonable crop rotation, strengthening water and fertilizer management, protecting natural enemies, releasing natural enemies, and controlling insects with insects. In addition, there are also control methods: at the initial stage of the occurrence of the disease, 0.26% matrine was sprayed evenly with 1000 times of matrine, and when it occurred in a large area, it was sprayed evenly with 20% dicofol EC 1000 × 2000, or 1.8% avermectin EC 3000-4000 times. The control effect is better.

When planting lavender, you must understand its growth habits, and then choose an appropriate time to plant. The management should be strengthened in the later stage of planting, especially in the aspects of fertilizer and water and diseases and insect pests. Only by doing a good job can lavender grow healthily.
