本所土壤严重缺硼,历年来油菜产量不高,曾有一甘兰型品比试验田十余个品种全部“花而不实”,颗粒无收。随着施硼防治“花而不实”难题解决后,油菜产量有较大幅度的提高。我们在施用硼肥基础上,进一步改进栽培方法,10.26亩油菜平均亩产247.2斤,比去年亩产151.2斤,每亩增产96斤。这说明在缺硼的土壤上油菜能够高产。现把主要经验总结如下。
Our soil is seriously deficient in boron, rapeseed yield over the years is not high, there was a more than a dozen varieties of cultivars than the experimental field all “flowers and not real,” no income crop. With the application of boron to prevent and control “flower and not real” problem solved, the rapeseed yield more substantial increase. Based on the application of boron fertilizer, we further improved the cultivation methods. The average yield of 10.26 mu of rapeseed was 247.2 kg, 151.2 kg more than that of last year, and an increase of 96 kg per mu. This shows that rape can be productive on boron-deficient soil. The main experience is summarized as follows.
