Double-cropping rice based ecological ditch cultivation method for triple-cropping winter crops

Abstract

The invention discloses a double-cropping rice based ecological ditch cultivation method for triple-cropping winter crops, aiming to solve the problem about crop straw returning to field, soil aeration and water and fertilizer coupling. The double-cropping rice based ecological ditch cultivation method includes the steps of 1), executing ditching engineering in a late rice field; 2), performing water management before harvesting late rice; 3), treating late rice stalks; 4), utilizing a chained ditcher to clean ditches and spread out mud; 5), planting winter crops; 6), performing field management; 7), harvesting the winter crops. The double-cropping rice based ecological ditch cultivation method has the advantages that an arable layer structure of soil is changed; full amount field returning and deep burying treatment of the crop straws can be realized at one step, and meanwhile, fertilizer is deeply applied, utilization rate of the fertilizer can be increased; water content of ditch soil is lowered, soil aeration is improved, and utilization rate of natural precipitation can be improved; no-tillage and non-straw burning of the winter crops are realized, and ecological effect is obvious in that operation energy consumption, haze and irrigation water can be reduced.

Description

technical field [0001] The invention relates to a crop cultivation method, in particular to a double-cropping rice-based three-ripening winter cropping ecological box ditch cultivation method. Background technique [0002] The present invention relates to the field of winter crop cultivation, in particular to a double-cropping rice-based three-ripening winter crop ecological compartment ditch transplanting and cultivation method, background technology [0003] According to statistics, the total national grain output in 2013 exceeded 600 million tons, estimated based on the grain-to-stalk ratio of 1:1.2, plus other crop straws, the country’s annual production of straws exceeded 720 million tons, and straws contain a large amount of organic matter, nitrogen, phosphorus, potassium and Trace elements, the nutrient content of nitrogen, phosphorus and potassium in 720 million tons of straw is equivalent to more than 5.76 million tons of urea, more than 8.4 million tons of superpho...
