我县大面积推广棉花三组六行种植方式,对于增加棉田密度,促进粮棉增产,起到了很大作用,但窄行管理比较费工。1974年以来,我们在大面积种植方式调查和四级农科网作的种植方式改革试验中,都发现一窝(钵)双株比三组六行、四等行有很多优点,因此种植面积逐年扩大,1975年种植1.5万多亩,去年达到5.7万多亩。新建大队1,105亩夏粮,由于把三组六行改为一窝双株,减少了预留行面积,使夏粮播幅扩大到60%以上,去年夏粮平均亩产达442斤,1,153亩棉田,亩产皮棉200斤。万年二大队1,290亩夏粮,亩产337斤,1,158亩棉田,亩产皮棉180斤。粮棉获得双丰收,单产都超过了历史最高水平。
The large-scale popularization of three groups of six-row cotton planting methods in our county has played a significant role in increasing the density of cotton fields and boosting the output of grain and cotton, but narrow-row management is labor-intensive. Since 1974, we have found that a litter (pot) double strain has many advantages over the three groups of six rows and four rows in the large-scale planting survey and the cultivation experiment of four-level agricultural network. Therefore, the planting area Expand year by year, planted 15,000 acres in 1975, reached 57,000 mu last year. The new brigade 1,105 acres of summer grain, because the three groups of six lines into a litter double strain, reducing the reserved area, the summer grain sowing expanded to more than 60% last summer average grain yield of 442 kg, 1,153 acres of cotton fields, mu Produce lint 200 pounds. 1,290 mu of second-generation brigade in summer grain, 337 pounds per mu, 1,158 acres of cotton fields, 180 pounds of lint per mu. Grain and cotton double harvest, yield exceeded the highest level in history.
