Method for tilling rice stubble rape field without need of tilling and punching

Abstract

The invention discloses a method needing no tilling and punching for tilling rice stubble rape field, which comprises the following steps: (A) culturing ridges with surface width of 100 cm and furrow width of 40 cm; (B) applying basal fertilizer; (C) transplanting two rows of rapes in each ridge, with every two adjacent rapes keeping a spacing of 15 cm and every two adjacent rows of rapes keepinga spacing of 60 cm, wherein root of the rape transplanted to moist field blocks faces to the middle of the ridges, clings to the field surface and is pressed by smalll clods, root of the rape transplanted to muddy field blocks faces to the middle of the ridges and is directly pressed on the field surface and root of the rape transplanted to dry field blocks faces to the middle of the ridges, clings to the field surface and is pressed by crushed clods; (D) returning total rice straw to the rice stubble rape field, namely, evenly spreading the rice straw which is not short on ridge surfaces between every two rows of rapes; (E) heapping the rapes in deep furrows, namely, digging ridge furrows with depth of 20 cm below the field surface for 3 days after the rape is transplanted and evenly earthing up upturned soil on ridge surfaces at the root of the rape; and (F) daily managing the rice stubble rape field. The invention can omit the processes of drying upturned soil, crushing upturned soil, punching, and the like, does not delay seasons, has high waterlogging resistance and effectively solves the problem of returning total rice straw to the rice stubble rape field.

Description

technical field [0001] The invention relates to a cultivation method for rapeseed, in particular to a cultivation method for transplanting rice stubble to rapeseed. Background technique [0002] Rapeseed is an important oil crop in my country with a long history of cultivation. Planting winter rapeseed after rice harvest is the main stubble layout of rapeseed production in my country, and the farming method has developed from tillage planting to no-tillage planting. According to statistics from Jiangsu Provincial Department of Agriculture and Forestry in 2006, the planting area of ​​rapeseed in the province is 8.86 million mu, most of which are rice, and a few are dry crops such as corn and cotton. 24.4%; stubble transplanting planting area was 4.98 million mu, accounting for 56.3%; direct seeding planting area was 1.71 million mu, accounting for 19.3%. [0003] At present, no-tillage planting method is adopted for transplanting rice stubble into rapeseed, and the specific...
