Farmland wind-erosion-preventing planting method in desert oasis areas

Abstract

The present invention discloses a farmland wind-erosion-preventing planting method in desert oasis areas. Wheat is sown in late ten-day of March of the first year, after the wheat is harvested, high stubble and straw covering are conducted, no-till is conducted, winter rape is replanted in a timely manner, corn is sown after the rape is harvested the following year, harvesting is conducted in thesame year, crop planting and farming pattern of the third year are the same as those of the first year, crop planting and farming pattern of the fourth year is the same as those of the second year, and the cycle is repeated; monocropping wheat is applied with 225 kg.hm<-2> of a nitrogen fertilizer and applied with 150 kg.hm<-2> of a P2O5 phosphorus fertilizer, and the winter rape is applied with 300 kg.hm<-2> of ammonium dihydrogen phosphate before sowing; 10 days after turning to green and in an initial flowering stage, 225 kg.hm<-2> of urea or ammonium nitrate is applied respectively combined with irrigation; and corn is applied with 360 kg.hm<-2> of the nitrogen fertilizer and 225 kg.hm<-2> of the P2O5 phosphorus fertilizer. Beneficial effects are as follows: the technology can increase soil cover of farmlands, reduces soil wind erosion caused by soil bareness, and can also maintain high and stable crop yields.

Description

technical field

[0001] The invention relates to a planting and farming method of no-tillage rotation of crops in the field of agriculture, in particular to a planting method for preventing wind erosion of farmland in desert oasis areas. Background technique

[0002] Soil wind erosion refers to the process of loose soil materials being blown up, transported and accumulated by the wind, and the surface materials are eroded by the particles blown by the wind. It is a complex physical process with many influencing factors, including natural and man-made. of. Due to wind erosion, the redistribution of soil particles in space and the sorting of soil particles by wind have a profound impact on the affected soil, soil-related micro-topography, and agricultural production activities. At the same time, in the process of soil wind erosion, a large number of aerosol particles will be produced, and these particles will be suspended in the atmosphere, causing sandstorms in the area and s...
