Embodiment Construction

[0047] A three-cropping late rice ecological ditch direct seeding cultivation method based on double-cropping rice is characterized in that it comprises the following steps:

[0048] (1) Carry out the ditch project in the early rice field: before transplanting or directing the early rice, arrange the field into a side surface, with a width of 70~80cm, a width of 15~20 cm, and a depth of 20~25cm;

[0049] (2) Water management of early rice before harvest: Sun hard surface, but keep 1~3 cm water layer in the ditch, which not only ensures the smooth operation of the harvester, but also prevents the ditch from drying out;

[0050] (3) Early rice stalk treatment: After the early rice is mature, use a combine harvester to harvest crops. If the harvester has its own grass-crushing function, then the crop stalks are evenly chopped; if the harvester does not have the grass-crushing function, widen the harvest The machine discharge opening expands the scattered surface of the stalks, and the s...

Abstract

The invention discloses a double-cropping rice based ecological ditch direct-seeding 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 direct-seeding 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), directly seeding late rice; 6), performing field management; 7), harvesting the late rice. The double-cropping rice based ecological ditch direct-seeding 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 of the 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 three-cropping late rice ecological ditch direct seeding cultivation method based on double-cropping rice. Background technique [0002] According to statistics, the total national grain output in 2013 exceeded 600 million tons. Estimated based on the ratio of grains to stalks of 1:1.2, plus other crop stalks, the country’s annual production of stalks exceeds 720 million tons. The stalks contain a lot of organic matter and nitrogen. Phosphorus, potassium and trace elements, the nutrient content of nitrogen, phosphorus and potassium in 720 million tons of stems 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 the return of crop stalks to the field or mulching is an effective measure to increase yield. Generally speaking, the yield can be incr...
