这个材料较深入细致地调查总结了三角村大队一九七三年二棉一粮间作套种的经验和科学道理。一九七四年该队二棉一粮间作套种又扩大到五百六十四亩,尺带改进为七尺一带,夏粮产量,平均每一自然亩棉花与大麦间作套种的,大麦产量是三百八十斤,按棉七五粮二五比例折合亩产一千五百二十斤,棉花与小麦间套种的,小麦产量是五百三十斤,折合亩产二千一百二十斤;棉花就目前长势和座桃情况看也好于去年。他们根据三年来二棉一粮间套种高产稳产的实验结果,计划一九七五年全大队能保证灌溉的耕地普遍采用这种种植方武,种法将又有两项改革,一是提早在今年九月二十五日前,用人力在棉行里锄开沟、手撒籽播种小麦(淘汰棉花与大麦间套种),拔棉柴后再复盖一层农家肥,浇一次水;二是一部分面积试行改七尺一带为一丈四尺一带,更便于管理。他们的经验和创造精神值得学习。
This material investigates in depth and sums up the experiences and scientific truths of the Triangle Village Brigade in 1973 in the inter-crop intercropping of two cotton and one grain. In 1974, the two-cotton-grain intercropping intercropping system was expanded to 564 acres with an improvement of seven feet per square foot. For summer grain production, intercropping was conducted on average with each of the natural acres of cotton and barley. The yield of barley was three One hundred and eighty catties, according to twenty-five cotton equivalent to seventeen five grain yield of 1500 kg per mu, intercropping cotton and wheat, wheat yield is 500 pounds, equivalent to 2120 kg per mu ; Cotton on the current situation and the peach situation is also better than last year. According to the experimental results of the high and stable intercropping of two cotton and one grain intercropping in the past three years, they plan to use the planting barbaric force in the irrigation of arable land in 1975. There will be another two reforms in the cultivation method. First, September 25 this year, with human hoe ditching in the cotton line, hand-seed sowing wheat (out of cotton and barley interplanting), pull cottonwood and then covered with a layer of manure, pouring water; second is Part of the trial area to change seven feet a foot four feet area, more manageable. Their experience and creativity are worth learning.
