在一定氮钾水平下,适当的磷硼配施可使油菜增产二倍以上,N:P_2O_5:K_2O:硼酸为1:0.7:0.7:0.15%(喷施浓度)时增产最显著。油菜籽中磷硼含量与磷硼肥用量呈正相关,钾含量与施磷量成正相关。适量磷硼配施的籽粒含氮量低于对照。施磷可提高籽粒脂肪含量。
Under a certain nitrogen and potassium level, the appropriate phosphorus and boron fertilizers could increase the yield of rapeseed more than two times. The yield was the most significant when N: P_2O_5: K_2O: boric acid was 1: 0.7: 0.7: 0.15% (spraying concentration) The content of phosphorus and boron in rapeseed was positively correlated with the content of phosphorus and boron, and the content of potassium was positively correlated with the content of phosphorus. Appropriate amount of phosphorus and boron combined with the grain nitrogen content is lower than the control. Phosphorus can increase grain fat content.
