本省栽培油菜历史悠久,经验丰富。大跃进以来,各地创造了很多丰产纪录,群众在油菜栽培技术上有了不少的革新和创造。在施肥技术上有根据不同施肥水平而定的“冬养春发”“冬壮春发”与“冬春双发”三种不同的施肥措施。一般大田生产上,多采用“冬养春发”,至于创造亩产300～500斤以上的高产油菜,目前有“冬壮春发”与“冬春双发”两种措施。“冬壮”与“冬发”是在不同施肥水平下,油菜各季表现出不同的生育程度。根据调查,促使油菜
The province has a long history of cultivation of rapeseed, experienced. Since the Great Leap Forward, many high yield records have been created in various places and the masses have made a lot of innovations and innovations in rape cultivation techniques. There are three different fertilization measures according to different fertilization levels, such as “winter raise spring hair”, “winter strong spring hair” and “winter and spring double hair”. In general field production, the use of “winter raise spring hair”, as to create a yield of more than 300 to 500 pounds of high-yield rape, there are “winter strong spring” and “winter and spring double” two measures. “Winter strong” and “winter hair” are different fertilization levels, rape showed different levels of fertility each season. According to the survey, prompting rape
