A kind of dryland crop micro-ridge mixed cultivation method

Abstract

The invention discloses a micro-ridge mixed-sowing cultivation method for dryland crops, comprising S1, clearing ditch and drainage in dryland; S2, harvesting the previous crop, leaving the stubble and crushing the straw of the previous crop and spreading it on the remaining stubble; S3, in the dryland Open a ditch to form an ecological ditch; S4, flatten the upright stubble and crushed straw on the box surface to form an underlying surface, and shape the seed fertilizer and mud compound into a ridge shape and fall on the underlying surface, Ecological ridges are formed, multiple ecological ridges are formed between adjacent ecological ditches, and ecological recesses are formed between adjacent ecological ridges. After sowing, a horse-racing water is irrigated; mixed. First, the ecological ridge is used as a medium to wrap organisms and nutrients, keeping warm, moisturizing, water-permeable and breathable; second, it is used as a donor to provide water and nutrients for the organisms. The seeds that have been selected in the ridge grow faster than the weed seeds inside and outside the ridge, and take root and grow leaves smoothly.

Description

technical field [0001] The invention relates to a dryland crop cultivation method, in particular to a dryland crop micro-ridge mixed cultivation method. Background technique [0002] my country's agricultural resources and environment are under the dual coercion of exogenous pollution and endogenous pollution. The non-point source pollution caused by agriculture has exceeded that of industry, and the sustainable development of agriculture has encountered a bottleneck. According to statistics, in 2018, the use of chemical fertilizers and pesticides in China reached 60 million tons (pure) and 300,000 tons (100 tons) respectively, while the utilization rate of chemical fertilizers was only about 35%, and pesticide residues were large, resulting in soil degradation, nutrient loss, Waste of resources; environmental pollution, product quality decline. The annual sown area of ​​dryland crops exceeds 1 billion mu, and the total output of dryland crops in my country exceeds 400 mill...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is, in order to overcome the problems of crop stalk returning to dry land affecting cultivation, low utilization rate, large amount of chemical fertilizer, unreasonable time and amount of topdressing in dryland crop production, and to avoid the influence of fertilizer basal application on seeding. To improve the emergence rate and seedling rate of no-tillage and dry-seed crops in dry land, the invention provides a micro-ridge mixed-sowing cultivation method for dry-land crops. The purpose of fertilizing, reducing costs, and fertilizing the soil
