No-tillage no-hole cultivation method for direct-sowing rape in rice stubble

Abstract

The invention discloses a no-tillage no-hole cultivation method for direct-sowing rape in rice stubble, comprising the following steps of: A) making ridges with the ridge surface of 100cm in width andridge furrow of 40cm in width; B) returning the total straws into fields, and uniformly covering the straws without cutting to be short in 45cm of the middle of the ridge surface; C) direct-sowing rape: sowing the rape in 20 to 28cm from the ridge furrows and sowing two lines of rape for each ridge strip; D) applying basic fertilizer; E) blocking water in deep furrows, hoeing the ridge furrows tobe below 20cm after rapes are sowed for two days, uniformly carrying the furrows on the blank amplitude of the ridge surface; and F) field management: doing well in daily field management. The no-tillage no-hole cultivation method saves the procedures of drying furrows, breaking furrows, making cavities and the like, saves labor, time and cost, does not miss the season, has high waterlogging resistance, can effectively solve the problem of returning the total straws in the rape field into field and realizes continuous adding of fertilizer and improvement of soil, thus improving the economic,social and ecological benefits.

Description

No-tillage and no-hole tillage method for direct-seeding rapeseed with rice stubble technical field The invention relates to a cultivation method of rapeseed, in particular to a cultivation method of rice stubble direct seeding rapeseed. Background technique 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. The farming method has developed from plowing planting to no-till planting, and the cultivation method has developed from seedling transplanting to direct seeding. 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 m...
