研究余庆县海拔800m稻油两熟地区不同移栽密度对优质杂交油菜贵杂4号生长发育及其产量的影响,试验表明不同移栽密度显著影响油菜产量,密度间差异达到极显著水平,以栽6000～7000株／667m~2产量最高,产量分别为196.0～182.3kg／667m~2。
The effects of different transplanting densities on the growth and yield of high quality hybrid rape Guizazao No.4 at 800m above sea level in Yuqing County were studied. The results showed that different transplanting density significantly affected the yield and density of rapeseed at extremely significant level, In order to plant 6000 ~ 7000 plants / 667m ~ 2 the highest yield, the yield was 196.0 ~ 182.3kg / 667m ~ 2.
