花生播前分级选种,对获得全苗、壮苗,克服大小株的差异,达到均衡增产起一定作用。为了测定分级粒选的增产效果,1982年我站分别在百尺所、姜家畦、埠前、南小城等四个大队进行了花生分级粒选增产效果试验。结果证明,一级米(百粒重90克)四处试验,平均亩产荚果572.8斤,比混合米(百粒重80克)亩产517.5斤,增产
Peanut sowing before grading, access to the whole seedlings, seedlings, to overcome the differences between the size of plants to achieve a balanced increase in production play a role. In order to determine the effect of grading granulation on yield increase, in 1982, we carried out peanut grading grain-increasing yield test in four batches including Baichang, Jiangjiawan, Buqian and Nanchengcheng respectively. The results show that a rice (90 weight 90 grams) four trials, the average per-mu yield of 572.8 pounds, than mixed rice (100-grain weight 80 grams) 517.5 pounds per mu yield increase
