—九七六年我队种植杂交水稻130亩,据8个生产队67亩杂交水稻的调查,平均亩产895斤,其中第二、五两个生产队共7亩,平均亩产达1050斤。一般比当地种植时间较长较稳产的“广二矮5号”每亩增产100~150斤,比“广陆矮4号”增产50~100斤。大队农科组的4.79亩三熟三高产试验田,平均亩产3144斤,其中一丘1.25亩种植杂交晚稻,平均亩产1376斤,三熟亩产达3295斤。杂交水稻能获得高产,主要抓了以下几条技术措施。一、选择强优势组合杂交水稻固然都具有优势,但不同的组合,所表现的优势却有很大的差别。对于高产田块来说,必须选择强优势的,特别是注意选择分蘖力强,茎稈粗壮,耐肥抗倒,穗大粒多,结实高的组合。两年来我们共试种了珍汕97×463、二九矮4号×IR24、珍汕97_(A)×IR661、二
- In 1976, we planted 130 hectares of hybrid rice. According to the investigation of 67 mu hybrid rice of 8 production teams, the average yield per mu is 895 kg, of which the second and fifth teams are 7 mu and the average mu production is 1050 kg . Generally longer than the local planting more stable yield “Guang Er short 5” per mu yield 100 ~ 150 pounds, than the “Guang Lu short 4” increased production of 50 to 100 pounds. The brigade agricultural group of 4.79 acres of three cooked three high-yielding experimental field, the average yield of 3144 pounds, of which 1.25 acres of hybrid rice planting late rice, the average yield of 1376 pounds, three acres of mu produce up to 3295 pounds. Hybrid rice can get high yield, mainly caught the following technical measures. First, the choice of strong combination of hybrid rice has advantages, but different combinations, the advantages shown are very different. For high-yield plots, we must choose a strong advantage, in particular, pay attention to choose strong tillering ability, stalks sturdy, resistant to lodging, spike large grain, strong combination of high. In the past two years, we have planted a total of 97 × 463, Shanshan 97_ (A) × IR661,
