采用大田小区试验研究种植密度和施肥量对湘杂油763生长和产量的影响.结果表明:密度和施肥量对湘杂油763收获期的农艺性状和产量构成因素均有显著影响.施肥量因素对油菜农艺性状和产量构成因素的影响大于密度因素.本试验以M3N2、M3N3,处理籽粒产量较高,因此湖南湘杂油763种植中N、P2O5、K2O、B的施用量和播种密度分别以180、90、157.5、0.9 kg/hm2、15万-22.5万株/hm2为宜,可以减少成本,提高菜籽产量,提高经济效益.

A field plot experiment was conducted to study the effects of different planting densities and fertilizer rates on yield and growth of Xiangzayou763.The results showed that there were significant effects of different planting densities and fertilizer rates on agronomic characters and yield components of Xiangzayou763 at harvest period,in which the effect of fertilizer rate was larger than the effect of planting density on agronomic characters and yield components of Xiangzayou763;the seed yield of Xiangzayou763 was larger in treatments of M3N2 and M3N3.Therefore,the appropriate fertilizer rate...
