Water-saving and fertilizer-saving method of crop rotation of winter wheat and summer corn

Abstract

The invention discloses a water-saving and fertilizer-saving method of crop rotation of winter wheat and summer corn, and belongs to the technical field of agricultural planting. The water-saving andfertilizer-saving method includes the steps: applying base fertilizer again before sowing of winter wheat, crushing corn stalks evenly, covering wheat planting rows with the crushed corn stalks, performing winter irrigation once after emergence of wheat seedlings, performing topdressing of urea at the jointing stage, applying foliar fertilizer A at the filling stage, crushing straw obtained afterharvest of winter wheat, returning the crushed straw to the field, then performing deep tillage and drying on the planting field 1-2 times, applying base fertilizer of nitrogen-phosphorus-potassium compound fertilizer before sowing of the summer corn, adopting a cultivation mode of ridge culture, covering a mulching film, performing irrigation once at the jointing stage, applying foliar fertilizerB from the tasseling stage to the flowering stage, and applying the foliar fertilizer B again in the grain formation period, wherein the foliar fertilizer A is prepared from the following materials:in percent by mass, 50-80% of humic acid, 25-50% of glycyrrhiza polysaccharide and 2-20% of boric acid, and the foliar fertilizer B is prepared from the following raw materials: in percent by mass, 50-80% of humic acid, 25-50% of glycyrrhiza polysaccharide and 5-20% of potassium nitrate. Through the water-fertilizer management method, water and fertilizer are saved, and meanwhile, the winter wheatand summer corn can have high yield.

Description

Technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a water-saving and fertilizer-saving method for winter wheat and summer corn rotation. Background technique [0002] During the long-term development of my country’s social economy, agriculture has always played an extremely important basic role. In the development of agricultural economy, both wheat and corn are very important crops. The planting and yield of wheat and corn will play a role in the development of agriculture. To a certain effect. With the rapid development of roads, construction, and industry in China, the available arable land area has been continuously reduced. Therefore, the method of winter wheat and summer corn rotation is proposed. However, the current rotation method has relatively reduced planting yield and increased water and fertilizer costs. Therefore, it is necessary to treat winter wheat and summer corn. The water-saving and fertilizer-savin...

Problems solved by technology

With the rapid development of roads, buildings and industries in our country, the area of ​​available arable land is decreasing, so the method of winter wheat and summer maize rotation is proposed, but the current crop rotation method is relatively low in planting yield, and the cost of water and fertilizer is increased. Therefore, it is necessary to improve winter wheat and summer maize The water and fertilizer saving method of crop rotation needs further research to achieve the purpose of reducing planting costs and increasing crop yields
