Abstract

The invention relates to the technical field of planting of double-cropping rice, specifically to a winter multiple-cropping crop-rotation planting mode of a double-cropping rice field. The winter multiple-cropping crop-rotation planting mode of the double-cropping rice field includes the following steps: step 1, planting of winter crops, wherein the winter crops include potatoes, Astragalus sinicus and oilseed rape, and potatoes, Astragalus sinicus and oilseed rape are planted alternately year by year; step 2, planting of early rice: performing sowing from March 20th to March 30th, performingtransplantation from April 25th to May 5th, and performing harvest from July 15th to July 25th; step 3, planting of late rice: performing sowing from June 10th to June 20th, performing transplantation from July 20th to July 30th, and performing harvest from October 15th to October 25th. In the scheme, the content of total organic carbon and total nitrogen in soil of the double-cropping rice fieldcan be stabilized and increased through crop rotation of potatoes, Astragalus sinicus and oilseed rape in winter, so that the problem is solved that later planting of double-cropping rice is affectedby reduction, caused by idleness of the field in winter, of soil fertility; and the yield and dry matter quality of the double-cropping rice can be stabilized and improved, meanwhile, and the economic benefits of the double-cropping rice field in winter can be increased, so that the problems of reduced soil quality and low economic benefits in an existing winter planting mode of the double-cropping rice field are solved.

Description

technical field [0001] The invention relates to the technical field of double-cropping rice planting, in particular to a double-cropping rice field winter multiple crop rotation planting mode. Background technique [0002] The middle and lower reaches of the Yangtze River are the main production areas of double-cropping rice in my country, and "winter slack-double-cropping rice" and "milk vetch-double-cropping rice" are the main planting modes of double-cropping rice fields at present. Currently, both models have significant limitations. The "winter slack-double-cropping rice" model leaves farmland idle in winter, leading to large-scale farmland abandonment in winter, resulting in waste of light, heat, water, and soil resources, which seriously affects the productivity of double-cropping rice fields; It solves the problem of idle farmland soil in winter, and can improve farmland soil fertility to a certain extent, thereby increasing the yield of double-cropping rice. Howeve...
