高含油量油菜品种‘沪油杂8号’肥料运筹技术初探

摘要

对高含油量杂交双低油菜品种‘沪油杂8号’进行了氮肥施用量、氮肥运筹和施用硼肥的田间试验，结果表明：‘沪油杂8号’氮肥适宜施用量是270 kg？hm2；这时的氮肥基苗蜡肥与春薹肥施用比例为65％∶35％—70％∶30％，产量结构最佳，产量最高。%Field experiments of rape hybrid ‘Huyouza 8’with a high oil content and double low content in rapeseed were carried out under various nitrogen fertilizer rates and fertilization ratios and boron fertilize rates. The results showed that the appropriate nitrogen fertilizer rate was 270 kg?hm2 ,and the ratio of early-stage fertil-izer rate to later-stage fertilizer rate for shooting was 65%∶35%—70%∶30%,at which the yield components was the best and the yield was the highest.
