经几年试验,我们于1983年冬在黑林山区推广了春花生地冬季深耕技术。经对8,200亩深耕岭地测产、核实,平均亩产干果547.4斤,比对照(春季常规耕作,下同)每亩增收70.2斤,增产14.7%。最高产田块单产1006.8斤,比对照增收143.3斤,增产16.7%。其花生特点是:单株饱果多,双仁饱果多,百果重高。据调查,深耕地花生单株饱果12.6—15.7个,比对照增2.4—3.7个;双
After several years of experimentation, we popularized winter plowing techniques of spring peanuts in the winter of 1983 in the Heilongjiang Mountains. After 8,200 mu deep ridge farmland to test production, verify, the average per mu yield of 547.4 kg of dry fruit, compared with the control (spring conventional tillage, the same below) an increase of 70.2 pounds per mu, an increase of 14.7%. The highest yield plots yield 1006.8 kg, 143.3 kg more than the control income, an increase of 16.7%. Its peanut characteristics are: single fruit full fruit, double kernel full fruit, fruit high. According to the survey, 12.6-15.7 full-fledged peanuts per plant were grown, which was 2.4-3.7 more than the control; double
