Method for planting vegetable astragalus smicus to repair greenhouse vegetable successive cropping obstacles

Abstract

The invention provides a method for planting vegetable astragalus smicus to repair greenhouse vegetable successive cropping obstacles. On the middle ten days and the last ten days of September to thefirst ten days of November, furrows are cleaned after the preceding crop of vegetables are harvested, vegetable straw and weeds in a greenhouse vegetable field are cut off and moved out of the field or smashed and then evenly cover furrow compartments, then the field is irrigated with Paoma water or irrigated to be submerged for 2-3 days, then drainage and soil turning are carried out, the astragalus smicus is sown after compartment ditches are cleaned, and in the growth period of the astragalus smicus, water spray irrigation is carried out 1-2 times every week through greenhouse vegetable field facilities; when the astragalus smicus grows to the state that the plant height is 20-50 cm, the astragalus smicus is manually picked or mechanically divided into the compartments and partitioned or fresh and tender parts of tender shoots of the astragalus smicus are picked in a stripped mode, the picking time is from the bottom of November of the first year to the initial flowering period of the last ten days of March or the first days of April of the next year, astragalus smicus fresh grass non-watered ploughing and turning down are carried out in the full-blossom period of the astragalussmicus, during turning down, lime is cooperatively applied, field parcels are trimmed, and conventional vegetable planting is carried out after the furrows are cleaned. The weeds in the vegetable field are restrained and soil is fertilized by planting the astragalus smicus, soil organic matter is increased, the physical, chemical and microorganism properties of the soil are improved, and the soilof the vegetable field becomes more healthy.

Description

technical field [0001] The invention relates to a method for repairing continuous cropping obstacles of greenhouse vegetables with milk vetch for planting vegetables. Background technique [0002] Vegetables are important economic crops in my country. With the development of social economy and the improvement of residents' consumption demand, vegetables have become an important industry for national agricultural development and farmers' income increase. Vegetable production in facility greenhouses has become one of the most dynamic industries in my country's agriculture due to its small impact on environmental conditions, short planting cycle, high multiple cropping index, and high yield and benefit. In recent years, the cultivation area has continued to expand, and the degree of specialization and scale Continuous improvement plays an important role in the construction of China's vegetable basket project and in ensuring the dietary needs of residents. Due to the high cost o...

Problems solved by technology

Rotation of paddy and dry crops is easier to implement in open field vegetable fields, but it is difficult to operate in shed vegetable fields. Rotation with legumes such as soybeans has the problem of repeated planting seasons between bean crops and vegetables, and competition for land
