四川及华东各地,运用育苗移栽技术,于前作收后移栽棉花,使前作能充分成熟,棉花能适期播种,以增加两熟产量。但这项技术在华中麦棉合理间作地区的使用价值,迄今各方看法相差颇远,而育苗移栽的增产效果,亦有进行研究的必要。为此,1956年本所特布置了育苗移栽增产效果测定、营养钵育苗播种期和育苗移栽密度等三个试验。兹将研究方法、经过及结果,总结如下。
Sichuan and East China, the use of seedling transplanting techniques, after the transplanting of cotton in the former harvest, the former can be fully mature, cotton can be sown in order to increase the yield of two crops. However, the use of this technology in the reasonable intercropping of wheat and cotton in central China has so far been far-reaching. The stimulation effect of transplanting seedlings is also necessary for research. To this end, in 1956, the special arrangement of seedling transplanting yield test, nutrient bowl seedling seeding and seedling transplanting density three experiments. The research methods, the results and the results are summarized as follows.
