Is there a policy subsidy for growing leeks in the greenhouse? What are the related planting techniques?

When it comes to leek, everyone is very familiar with it. It is a kind of vegetable grown all over our country. Leek is full of vitality and generally grows well without worrying about it. However, in order to increase the yield of leek, the method of planting leek in greenhouse is widely used. Is there a policy subsidy for growing leeks in the greenhouse? What are the related planting techniques?

Is there a policy subsidy for growing leeks in the greenhouse?

Whether there is a policy subsidy for planting leek in the greenhouse needs to be based on the policies formulated by the local government at that time, the situation varies from place to place. According to the relevant information, we can learn that there are some subsidies for different projects in the greenhouse.

1. subsidies for infrastructure such as greenhouse film, apply to the Bureau of Agriculture for greenhouse film subsidy, skeleton subsidy and one needed in the greenhouse before the construction of the greenhouse.

Some gadgets.

2. Subsidy for irrigation facilities. At present, water-saving agriculture is advocated by the state. Drip irrigation for irrigation facilities in greenhouse can be applied to the Water Conservancy Bureau.

3. Greenhouse subsidy projects, greenhouses and other facilities can apply for the Ministry of Agriculture horticultural crop standard garden construction project, each project subsidy of 50-1 million yuan.

For the scale requirements, the first type of subsidy generally does not limit the size, the specific requirements and amount, please consult the Bureau of Agriculture; the second type of subsidy applies to the Water Conservancy Bureau.

The third type of project has the requirement of scale, which requires more than 200 mu of facilities.

2. Key points of planting techniques of leek in greenhouse

The main contents are as follows: 1. The choice of leek land. The site of leek in greenhouse should choose sandy loam with convenient transportation, good irrigation conditions and rich organic matter. The border is built in the north-south direction, with a width of 1.5 meters, a width of 0.6 meters and a length of 30-40 meters, with a greenhouse built every 2 borders.

2. The cultivation of strong roots is the basis of high yield and high benefit.

The biggest difference between the technical measures of root cultivation of leek in winter and that of leek in dormancy greenhouse is that it can promote its rapid growth, accumulate more nutrients and cultivate sturdy roots.

3. The appropriate time for buckling film should be before the local initial frost. If the buckle grows early, the yield peak comes early, and it is easy to senescence; if the buckle suffers from cold injury in the open field, it is easy to cause leaf tip rot, and once the leek turns into passive dormancy, it grows slowly after buckling the film.

4. Management and harvesting after buckling film. Generally, you can make a shallow cut before buckling the film, and buckle the film immediately after harvest, so that it is easy to operate. If the leek has not reached the harvest standard, the film should be buckled first in order to prevent frost injury, but it must be operated carefully to prevent damage to the leek plant. In the initial stage of buckling film, the indoor temperature is higher, so it is necessary to strengthen ventilation to prevent excessive growth, and generally maintain no more than 25 ℃ during the day. With the decrease of external temperature, the air release volume was gradually reduced, keeping 20-25 ℃ in the daytime and 5-10 ℃ at night.

After that, with the decrease of external temperature, the grass and paper quilts were covered at night, and covered early and uncovered late to strengthen the thermal insulation performance. After the production of leek buckle film in winter, it still needs topdressing and watering. Generally, when the plant height is about 10 cm, 40-50 kg ammonium sulfate is applied per mu between rows, ridges are watered, and when the plant height is 20 cm, ridges are cultivated again. Water 2-3 days before harvest. It is necessary to strengthen ventilation and dehumidification after each water, but pay attention to prevent frost damage.

Winter production of leek, if the growth is strong, the harvest period can be extended from October to February-March of the following year, after harvesting and cutting off leek roots, fruit and vegetable production. Attention should be paid to the shallowness of the knife for each harvest so as not to affect the growth of the next crop. But the last harvest, because cut off the leek root, can be cut as deep as possible.

5. strengthen the prevention and control of diseases and insect pests. Due to the frequent watering in the greenhouse and high humidity, attention should be paid to the prevention and control of Botrytis cinerea, which can be fumigated with Sukeling smoke agent after each watering, and the disabled body should be removed in time. Peel off the diseased leaves during each harvest and bury them deeply.
