摘要
采用田间试验与实验室检测相结合的研究方法,包括油菜摘薹适期研究、大区对比试验、菜薹营养结构分析等以及摘薹次数研究进展概述。试验结果表明,摘薹后,油菜产量结构发生明显变化,比单收菜籽减产菜籽17.7%,但纯收入提高了33.7%,投入产出比约1∶3.5;甘蓝型油菜双低油菜薹是一种品质优良的绿色蔬菜;薹高60 cm时为摘薹最佳时期;摘薹一次产值最高。
Field experiments combined with laboratory testing were used in this study, including the re search of suitable time to pick rape shoot, the degree of harvesting shoot, the contrast experiment of large blocks, nutrition structure analysis of shoot. The results indicated that after shoot harvest the product struc ture of rape appeared remarkable change. Rapeseed yield reduced 17.7% compared with harvest only rape seed, but net income increased 33.7% compared with CK. The ratio of input and output is 1：3.5. The shoot of Brassica napus rape is an excellent green vegetable. The suitable harvest time is when shoot is 60cm long. Harvesting shoot JUST 1 time is the best.
