Triple cropping late rice ecological ditch transplanting cultivating method based on double cropping rice

Abstract

The invention discloses a double-cropping rice based ecological ditch transplanting cultivation method for triple-cropping late rice, 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 transplanting cultivation method includes the steps of 1), executing ditch engineering in an early rice field; 2), performing water management before harvesting early rice; 3), treating early rice stalks; 4), allowing a chained ditcher to clean ditches and spread out mud; 5), transplanting late rice; 6), performing field management; 7), harvesting the late rice. The double-cropping rice based ecological ditch transplanting cultivation method has the advantages that an arable layer structure of soil is changed; deep application of fertilizer is benefited and utilization rate of the fertilizer is beneficially increased; water content of ditch soil is lowered, soil aeration is improved, and utilization rate of natural precipitation can be improved; no-tillage, no-stubble cleaning, no-straw burning and no-filling and soaking of field water in late rice transplanting are realized, ecological effect is obvious in that operation energy consumption, haze and irrigation water can be reduced, and pesticide stubble cleaning is omitted.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to a method for transplanting and cultivating a three-cropping late rice ecological ditch based on double-cropping rice. Background technique [0002] According to statistics, the total national grain output in 2013 exceeded 600 million tons. According to the grain-to-stalk ratio of 1:1.2, plus other crop straws, the national annual output of straw exceeded 720 million tons. The straw contains a lot of organic matter, nitrogen, phosphorus, potassium and 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 superphosphate, and more than 8.4 million tons of potassium sulfate. [0003] Studies have shown that crop straw returning to the field by pressing or mulching is an effective measure to increase production, which can generally increase production by more ...
