[0031] Cotton field preparation:

[0032] Super deep plowing and fertilizer input:

[0033] After picking up the seed cotton that is normally blown out in the cotton field, on November 10-12, 2011, the residual film recycling machine was used, combined with manual work, to clean up the residual film in the field, and then the cotton straw was crushed and thrown on the surface of the cotton field with a straw crushing and returning machine, so as to achieve Crop stalks were crushed and returned to the field, and on November 12, 2011, about 4.5m of organic fertilizer was added to farm animals. 3 At the same time, 80kg / mu of humic acid phosphate fertilizer and potassium sulfate (K) produced by Xinjiang Qingsong Building Materials Chemical (Group) Co., Ltd. 2 SO 4 ) 10kg / mu, no potassium chloride, sodium nitrate and other chemical fertilizers with chloride ions or sodium ions were added. On November 13-14 of that year, a suspended single-share turning plow w...

Abstract

The invention relates to a method for constructing a soil ploughing layer of a south-Xinjiang oasis drop-irrigation continuous-cropping middle-low-yield cotton field. The method includes the steps that before sowing in the cotton field, straw of last crops is smashed and returned to the field; farmyard manure and chemical fertilizer are applied; deep ploughing, cotton field flattening and super-deep scarification are conducted; irrigation is conducted before sowing; sowing is conducted; furrows are dug in the cotton field, and anti-salt plants are planted; a windbreak tree belt is built on the periphery of the cotton field; a water-irrigation and drainage trench system is built; field management is conducted. After the method is adopted, the surveying result shows that the soil water content in the seedling stage is increased by 0.5%, rapidly-available potassium of the ploughing layer is increased by 35.2%, the temperature of soil 5 cm lower than films is increased by 0.6 DEG C, the thickness of the ploughing layer in the seedling period is increased by 7.1 cm, the salt content of soil is reduced by 2.1 g/kg, the soil porosity is increased by 8.5%, the soil penetration resistance (PSI) is reduced by 130, the soil bulk density is reduced by 0.11 g/cm<3>, the pH value of soil is reduced by 0.4, the residual film content of soil of the ploughing layer is reduced by 11.3 kg per mu, premature senescence of the cotton field is avoided, the yield of seed cotton is increased by 57.5 kg per mu, and therefore the method has the soil-improving and yield-increasing effects and can meet production requirements.

Description

technical field [0001] The invention relates to a method for constructing soil plow layers in low-yield cotton fields under drip irrigation continuous cropping in southern Xinjiang oases. Background technique [0002] The oasis in southern Xinjiang has a unique natural ecological environment. The cotton area is far away from the ocean. It is very cold in winter and hot in summer. It is dry and less rainy. The air is dry and the soil evaporation is abnormally large. When the spring season changes, it is frequently threatened by severe wind and sand disasters. Taking Awati County, which is located in the relatively center of southern Xinjiang, as an example, its annual average temperature is 10.4°C, and the average temperature in the hottest month (July) is 24.2°C. The extreme maximum temperature is 40.4°C, the coldest month (January) average temperature is -8.3°C, the extreme minimum temperature is -25°C, and the effective accumulated temperature ≥10°C is 4147-4658°C; the ann...
