What is the leek cultivation technique? Leek cultivation techniques

1.Select the leek seeds with full fruit and stir them with pesticides.

The seeds are sown after loosening the soil, after which a thin layer of soil is spread, then watered, and finally covered with a film. After waiting for three days, the seedlings slowly grow, and the steps of selecting the seedlings are completed.

2.Seedling managementAfter the seedlings grow, the weeds in the field should be removed and weeded frequently. You can spray pesticides every other week, and if the weather is hot and dry, you need to water more to prevent leek yellow from being sunburned. Do a good job in seedling management and lay a solid foundation for the growth of leek yellow.

3.The planting environment is set up with a suitable planting environment, leeks are not resistant to high temperatures, and the suitable temperature for growth is 18. Leeks like light, and the light time is long, which can promote their photosynthesis and increase the quality of leeks.

It is necessary to ensure that the soil in which leeks are planted is fertile, and that there is enough moisture, otherwise the seedlings are prone to sunburn.

4.In order to do a good job in the management of the planting period, we must first loosen the soil and fertilize it in time, and water more to provide water and nutrients; secondly, it should be planted in a reasonable space, and transplantation can be carried out appropriately; In addition, it is necessary to clean and prune in time, in the process of planting leek yellow, it is inevitable that the plants will be sunburned or die, and they need to be pruned and cleaned.

The cultivation techniques of leeks are:Cultivating strong roots is the basis of leek production. It is related to the yield and quality of leeks.

Sow seeds at the right time. Generally, varieties with strong cold resistance, high yield and disease resistance, such as Ping Leek 4, Snow Leek King and 791, are selected for direct seeding in the field or interplanting in wheat fields before and after the Lixia Festival.

Apply plantar fertilizer before sowing, water the bottom water, fine land preparation, use about kilograms of seeds per mu, open a ditch according to the row spacing of 20 23 cm, sprinkle the seeds evenly in the ditch, sweep a thin layer of soil with a soft wool broom, step on it lightly, and then water it for the first time, water the second time when the ground is dry and wet, and water the third time when the ground is not dry.

Field Management:Before the beginning of autumn, it is generally not topdressed, in order to prevent excessive growth or rotten seedlings, it is necessary to water frequently, cultivate and weed. After the beginning of autumn, top dressing begins to grow strong roots.

The first time is 50 kg of urea per mu or 50 kg of cake fertilizer, and the second fertilizer is reapplied before and after the Bailu Festival, and 20 25 kg of urea per mu. Weeds should be removed frequently throughout the growth period, with less or no mowing, so as to strengthen the roots. After the beginning of winter to before the light snow, the dead leaves will be removed, and the leek roots will be set aside.

The leek planting technology is carried out from the planting time, soil conditions, seed treatment, planting, water and fertilizer management, etc.

1. Planting time.

Leeks can be planted twice a year, in spring and autumn, of which spring sowing should be in mid to late March and early to mid April, and autumn sowing should be done in mid to late August to early to mid September, when the temperature is suitable, which is conducive to plant growth.

2. Soil conditions.

To plant leeks, you must use acidic soil, usually with mountain soil as the substrate, and at the same time mix plant ash and humus, mix them well, and add vegetable cakes as base fertilizer at the bottom to increase the fertility of the plot and let the leeks grow in fertile soil.

3. Seed treatment.

First of all, the leek seeds are soaked in warm water at 35-40 degrees, soaked for 12-24 hours after natural cooling, and the dormant state of the seed acorn is broken, and the soaking process picks out the straw and bad seeds, and the soaked seeds are put into 2%-3% carbendazim solution for 15 minutes, and the treated seeds are put into a moist environment for germination, and the water and air are changed every day, and most of the seeds are exposed for about 2-3 days to be sown.

4. Carry out planting.

Leek planting generally with seeds or roots, seeds must be selected to the right variety, such as Shaoxing snow leek, Chengdu Ma Lin leek or Jiaxing white root, etc., the roots should be treated, the old roots and leaves are cut off, put into the rooting water to soak for 4-5 hours, then take out to dry, and finally plant the seeds or roots into the soil according to a certain interval.

5. Water and fertilizer management.

Leek watering to the soil moist shall prevail, if the temperature is low, but also reduce the amount of watering and watering times, leek planting should be timely top dressing, to cut the green before the top dressing twice, respectively in the seedling height of about 25 cm and seedling height of about 40 cm, with fully decomposed organic fertilizer, with urea, furrow application.

Leeks are leeks that grow in shady places without sunlight.

Therefore, leeks do not contain chlorophyll, and are rich in protein, vitamins, carotene and other nutrients.

Medicinal value. It can ** diarrhea, constipation and other diseases, and has high nutritional value, which can supplement some nutrients needed by the body.

How do you grow leeks yourself?

First of all, the leeks should be planted well, after the leeks are harvested, they are covered with a relatively dark oil paper that does not absorb sunlight, and then the leeks that grow out are not irradiated by the sun, and the color is yellow, which is the leeks sold in the market.

The planting methods and techniques of leeks are as follows:

First of all, you need to choose healthy leek seeds, soak them in water for a while, and then put them on a damp cloth to induce germination.

Prepare loose and fertile soil, disinfect the soil before use, and apply an appropriate amount of base fertilizer, which is conducive to the growth of leeks.

Plant the treated leeks in the soil, then cover with a thin layer of soil, and finally an appropriate amount of glue.

Planting skills: When the leek grows to about 20 cm, it is necessary to thin the seedlings and weeds properly, and apply an appropriate amount of water and fertilizer.

Leek is a yellowed leek produced by softening cultivation in a dark environment through measures such as soil cultivation and shading covering, and the young leaves are for people to eat, the leek is bright yellow in color, unique in flavor, refreshing in taste, and is deeply liked by consumers.

After planting leeks in life, harvest them first, and then choose some opaque oil paper to wrap the leeks, so that the leeks continue to grow in a dark environment that does not contact the sun, so that the leeks will gradually show a leek yellow appearance. Generally planting will be around March, the weather at this time gradually warms up, when planting leeks to remember to fertilize the leeks in time, weeding and other work, and so on, after the ready, the leeks at this time will have the first maturity, after the maturity period will be harvested from the root above the root, and then it can be planted after wrapping it with oil paper.

1. Select excellent varieties Choose excellent varieties suitable for local sowing, and generally choose green leeks with fast growth, high yield, cold resistance, fertilizer tolerance, disease resistance, strong tillering ability and wide leaves. 2. Plot selection The cultivation of leeks should be selected with fertile soil, deep soil layer, high organic matter content, and convenient drainage and irrigation conditions. 3. Leeks are only planted once, harvested vegetables for many years, and then do not need to plough, so before sowing, the soil must be turned deep to facilitate the development of the root system, the general soil layer is about 30cm deep, and it should be exposed to the sun for about a week after deep turning.

The ground is leveled, the large pieces of soil are broken, and the ground is prepared without or less base fertilizer, and then according to the size of the land, the convex and concave furrows in the north and south are made. Then when making a furrow, we should consider the problem of watering, according to the size of the plot to make the land into small pieces, you can add a "ten" ditch in the field, and open a ditch around it to facilitate watering. 4. Seed treatment Soak the seeds with about 50 water for 24 hours, this is not germination, the water is not easy to be too much, so wash it with water once a day, after 2 3 days, in 2 3 carbendazim dry and wet powder seed dressing for use, the seeds can be sown when they are white.

5. Sowing period Spring sowing is generally in late March and mid-April, and autumn sowing is generally in late August and mid-September. Leeks are generally sown and cultivated in spring and autumn each year. In the sowing amount per 667m2 kg, the sowing is opened in the east-west direction according to the row spacing of 75cm on the furrow surface, the bottom surface is flat, and the sowing furrow with a depth of about 18 20cm is convex and concave.

Dig the bottom of the ditch, then gently flatten the bottom of the ditch and sprinkle a thin layer of fine sand to fill in the soil gaps. Carefully leveled again, so as not to prevent the seeds from emerging unevenly, the seeds should be covered evenly and the depth should be consistent, and the seeds should be covered with a thin layer of fine sand after sowing until the seeds are not exposed to the thickness. Then use fully rotted human feces and urine to water the seeds, every 667 m2 need to be planted with 50% human feces and urine per 667 m2 need about 5500 plants, avoid continuous cropping with onion and garlic vegetables, leeks are perennial root vegetables, planted once for many years of harvest, every 667m2 apply manure 2500 3000kg, superphosphate 45kg, deep turning and fine rake.

When planting, it is advisable to shovel seedlings with shovels to reduce root damage, keep fibrous roots 3 5 cm, leaves 6 15 cm. The leeks in the planting are not harvested, and the robust bushes have been cultivated, so that they have strong absorption and assimilation organs, which can not only accumulate excessive nutrients, but also lay the foundation for growth and development and high yield in the next few years. After entering the vigorous period in autumn, it should be topdressed in stages, watering to promote plant growth, topdressing should be mainly nitrogen fertilizer, with a certain amount of phosphorus and potassium fertilizer, generally watering once every 6 7 days, top dressing once in 8 10 days, to meet the growth and development needs of leeks.

7. Field management (1) fertilizer and water management The amount of fertilizer required for the perennial growth of leeks is based on different cultivation purposes and the growth characteristics of different periods and the requirements for water and fertilizer. 7 In mid-August, pay attention to drainage, do not apply fertilizer, promote water and fertilizer in the early autumn, control fertilizer and water in the middle stage, and stop water in the later stage to control the long, until late October.
