通过土培及田间试验,研究了硼对双低油菜(D89)的生长、产量和油分的影响和硼素营养特点。结果表明:在缺硼的土壤上增施硼肥能提高菜籽产量和含油率;初步提出了D89的土壤和叶片中适宜、缺乏和硼中毒的含硼指标和硼在体内积累的特点。为合理施用硼肥提供了有益的资料。从而有助于“双低”油菜的推广。
The effects of boron on the growth, yield, oil content and boron nutrition of double low rape (D89) were studied by soil culture and field experiments. The results showed that adding boron fertilizer to boron-deficient soil could increase rapeseed yield and oil content. The suitable boron content and boron accumulation in soil and leaves of D89 were suggested. The reasonable application of boron fertilizer provides useful information. Thus contributing to the promotion of “double low” rapeseed.
