Problems solved by technology

The content of organic matter in saline-alkali soil is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops, so it is difficult for crops to promote seedlings
[0003] At present, there are precedents of planting rice and winter wheat in the improvement process of saline-alkali land, but the method of using rice and winter wheat rotation in the improvement process has not yet been carried out

Abstract

The invention discloses a rotation planting method of rice and winter wheat in saline-alkali land, and belongs to the technical field of crop planting in saline-alkali land. The rotation planting method of rice and winter wheat in saline-alkali land includes the steps of (1) weeding before ploughing, (2) dry soil preparation, (3) application of a soil-oriented conditioner and a base fertilizer, (4) rotary tillage and soil preparation, (5) soaking and beating, (6) water soil preparation, (7) rice planting, (8) rotary tillage of land, (9) wheat planting, and (10) rice rotation. The rotation planting method can not only achieve the effect of land improvement, but also achieve high crop high yields throughout a year, and the economic benefits are improved.

Description

Technical field [0001] The invention belongs to the technical field of crop planting in saline-alkali soils, and specifically relates to a rotation planting method of rice and winter wheat in saline-alkali soils. Background technique [0002] Saline-alkaline soil is the general term for saline soil and alkaline soil. Saline soil is alkaline, which contains high chloride or sulfate, but the pH value is not necessarily high. Alkaline soil is alkaline and has a high pH, ​​which contains carbonate or heavy phosphate. The content of organic matter in saline-alkali soil is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops, and crops are not easy to promote seedlings. [0003] At present, there are precedents for planting rice and winter wheat in the improvement process of saline-alkali land, but the method of using rice and winter wheat rotation in the improvement process has not yet been developed. Th...
