调整作物布局 提高光能利用率 近四年来,我县粮食作物平均亩产由400斤上升为721斤,年递增率为15.88％;大豆平均亩产由101斤上升为207斤,年递增率为19.65％。促成单产迅速提高,除上节讲过的增加土壤有机质,提高土壤肥力,实行科学施肥外,适当调整作物布局和品种布局,千方百计地提高光能利用率也是重要原因之一。
Adjust crop layout to improve the utilization of light energy The past four years, the average grain yield in our county increased from 400 kg to 721 pounds, the annual increment rate of 15.88%; average yield of soybean from 101 pounds to 207 pounds, the annual increment rate 19.65%. In addition to increasing soil organic matter, increasing soil fertility and implementing scientific fertilization as mentioned in the previous section, it is also one of the important reasons to adjust the crop layout and variety layout as appropriate and do everything possible to improve the utilization of light energy.
