摘要
试验表明 ,施用硼肥对油菜植株的生长发育、经济性状及产量有较大的影响。基肥施用硼肥可改善油菜叶片营养 ,667m2 施用 0 75kg时产量最高 ;基肥未施硼肥 ,中后期 667m2 根外喷施 0 2 - 0 4kg硼肥 ,可明显降低缺硼对油菜的影响;667m2 总施硼砂 1 0 5kg,分基肥、苔肥 ,花肥三个时期施用 。
The experiment showed that the application of boron fertilizer influenced the growth,the economical characteristics and the output of rape plant greatly.Applying boron fertilizer as the base fertilizer,the leaf nutrition on the rape could be improved.The output of rape would be the highest if 0.75kg of boron fertilizer was applied to the area of 667m 2 ;without any base fertilizer but 0.2-0.4kg/667m 2 of boron fertilizer was sprayed on rape plants in the middle and later stage,the influences of lacking of boron on rape would be lessened.The total amount of boron fertilizer of 1.05kg/667m 2 was applied as base fertilizer,coating fertilizer and flower fertilizer respectvely,the output effect of rape have been proved to be the greatest.
