八二年进行了少量的棉花砂子育苗移栽试验,八三年又在本县的大桥、黄岭、张家坂等地再次进行了砂子、火粪育苗移栽的多点试验,都取得了成功,效果较好,为棉花育苗移栽摸索了新的办法。现将结果简报如下:一、棉花采用砂子、火粪育苗移栽的原理棉花芽苗移栽的成活很高,已在全国推广,但只能在子叶阶段进行,适宜的移栽期很短。到了真叶阶段,棉苗的根系多,易断根伤苗,不带土移栽就难于成活,所以只能采用营养钵或方块育苗移栽。而砂子、火粪育苗移栽的基本原理,就是因为砂子、火粪
In 1982, a small amount of cotton sand seedling transplanting was carried out. In 1983 and again in the county’s Daqiao, Huangling and Zhangjiaban areas, more trials of sand and fire droppings transplanting were successfully conducted , The effect is better, and explore new ways for cotton seedling transplanting. Now the results of briefings are as follows: First, the cotton sand, fire manure seedlings transplanted cotton seedlings transplant transplanted high survival has been in the country to promote, but only in the cotyledon stage, the appropriate transplanting period is very short. To the true leaf stage, cotton seedling root system, easy to cut root injury seedlings, without soil transplanting is difficult to survive, so can only use nutrition bowl or box nursery transplanting. The sand, fire manure seedlings transplant the basic principle is that because of sand, fire dung
