High yield growing method of winter wheat

Abstract

The invention discloses a high yield growing method of winter wheat, which comprises the following steps: soaking seeds in biogas slurry, performing soil preparation through combining intensive cultivation before seeding, applying basal fertilizer, dressing biogas slurry at the later jointing stage of wheat, spraying leaf fertilizer at the booting stage of wheat, spraying biologics fertilizer at the heading stage of wheat and spraying water retention fertilizer at the watery stage of wheat; the growing method disclosed by the invention is convenient, practical and low in cost, reduces adverse effects of nitrogen fertilizer pollution and serious pesticide residue during production of high quality wheat, improves kernel quality, and solves the problems about high quality cultivation of wheat, resource utilization of agricultural wastes and agricultural sustainable development.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a high-yield planting method for winter wheat. Background technique [0002] Wheat is one of the main crops in northern China. In recent years, with the improvement of people's living standards, the society's demand for high-quality special wheat is increasing, and the planting area of ​​high-quality wheat is increasing rapidly. With the upgrading and processing of special flour products of processing enterprises With the continuous modernization of technology, the modern milling industry puts forward higher and higher requirements for the quality and stability of large quantities of commercial wheat. In order to produce wheat with high protein content, farmers in the north use excessive amounts of chemical fertilizers, which not only leads to soil compaction, but also nitrogen The utilization rate of nutrients is low, a large amount of nitrogen fertilizer is lost, and t...

[0002] Wheat is one of the main crops in northern China. In recent years, with the improvement of people's living standards, the society's demand for high-quality special wheat is increasing, and the planting area of ​​high-quality wheat is increasing rapidly. With the upgrading and processing of special flour products of processing enterprises With the continuous modernization of technology, the modern milling industry puts forward higher and higher requirements for the quality and stability of large quantities of commercial wheat. In order to produce wheat with high protein content, farmers in the north use excessive amounts of chemical fertilizers, which not only leads to soil compaction, but also nitrogen The utilization rate of nutrients is low, a large amount of nitrogen fertilizer is lost, and the environment is seriously polluted. With the improvement of the production conditions in the vast rural areas, the wheat yield level continues to increase. The increase in planting density and biomass will inevitably lead to the deterioration of the micro-ecological environment of the canopy, and the close Over the past few years, many impacts such as winter climate warming have caused major pests and diseases such as wheat rust, powdery mildew, and aphids to occur continuously, seriously affecting the high and stable yield of wheat, and reducing wheat processing and nutritional quality. Blind use of pesticides has led to environmental degradation, Water supply is polluted, plant diversity is reduced, insects produce resistance, and a series of problems, which also directly cause pesticide residues in grains to seriously exceed the standard, the hygienic quality is greatly affected, and food safety is worrying. The invention provides a kind of winter wheat High Yield Planting Methods
