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.
