Rotation ploughing and rotation planting method for paddy and dry crops and field transformation method and slurry used in rotation ploughing and rotation planting method

Abstract

The invention provides a crop rotation ploughing and crop rotation method for paddy and dry crops and a field transformation method and material used by the crop rotation ploughing and crop rotation method. By means of compensation of climate (temperature) by facility farmland (greenhouses), rotation tillage and rotation planting in spring, summer, autumn and winter achieve the effects of improving the total yield of crops all the year round and achieving the three-harvest of oil plants, grains and vegetables, and the effects and purposes of reducing plant diseases and insect pests of water crops, overcoming continuous cropping insect diseases of dry crops and reducing pesticides and herbicides are achieved. According to the method and the material, the capillary network structure which can effectively reduce the water seepage and leakage phenomena of a sandy soil field and improve the capability of conveying water below a ploughing soil layer upwards (the capillary phenomenon in the soil layer) to maintain the soil moisture content of an upper soil layer when drought occurs is constructed. The invention has the advantages of easily available raw materials and low cost. The method is simple, effective and reliable, and has positive significance in improving the quality, yield and food safety of the facility farmland and improving the economic and social benefits of the facility farmland.

Description

technical field [0001] The invention belongs to the technical field of agriculture, in particular to a method for rotation of paddy and dry crops, a field improvement method and slurry used therein. Background technique [0002] At present, facility farmland (such as greenhouses) located in the middle and lower reaches of the Yellow River in northern China, especially in the flooded areas of the Yellow River, is restricted by the water retention performance and soil structure of the field. This kind of greenhouse field can only grow dry crops but not water. Moreover, although these facility farmlands (such as greenhouses) have overcome the limitation of climate (temperature) conditions and can grow vegetables, melons and fruits and other dry crops all year round, there are excessive ( Repeated) application of pesticides, causing field pollution, and excessive pesticide residues in crops (vegetables, fruits and vegetables). In addition, the existing farmland improvement mate...

Problems solved by technology

[0002] At present, facility farmland (such as greenhouses) located in the middle and lower reaches of the Yellow River in northern China, especially in the flooded areas of the Yellow River, is restricted by the water retention performance and soil structure of the field. This kind of greenhouse field can only grow dry crops but not water. Moreover, although these facility farmlands (such as greenhouses) have overcome the limitation of climate (temperature) conditions and can grow vegetables, melons and fruits and other dry crops all year round, there are excessive ( Repeated) application of pesticides, causing field pollution, and excessive pesticide residues in crops (vegetables, fruits)

In addition, the existing farmland improvement materials, such as non-gelling wet phosphogypsum, cannot achieve the effect of water saving and moisture conservation on the characteristics and structure of the (moving) sand layer in the yellow flood zone.
