摘要
本试验研究了春油菜菜薹采摘后对经济效益的影响及不同播期对菜薹采摘后经济效益的影响。结果表明,油菜采摘菜薹后油菜籽产量显著减产,但经济效益显著增加;不同播种期对菜薹采摘后油菜的农艺性状及产量、效益有一定影响,适宜早播,有利于菜薹采摘后油菜的生长,为后期菜籽高产奠定基础,但在一定时间内影响效果不显著。以青杂7号为例,在4月中旬—5月中旬种植,效益差异不大,但超过5月下旬播种,会严重减产,效益明显降低。
This experiment studied the economic benefits of Spring Rape after bolting and the effects of different sowing dates on the economic benefits after bolting.The results showed that the yield of rapeseed would decrease significantly after bolting,but the economic benefits would increase significantly.Different sowing dates had certain effects on the agronomic characters,yield and benefit of Rape after picking.It was suitable for early sowing,which was conducive to the growth of Rape after picking,and laid the foundation for high yield of rapeseed in later stage,but the effect was not significant in a certain period of time.Taking Qingza No.7 as an example,there was little difference in benefit when it was planted from mid April to mid May.However,it was sown in late May,the yield would be seriously reduced and the benefit would be significantly reduced.
