一、育苗方式目前棉花育苗移栽的方式有营养钵育苗,熟土方块育苗,湖、塘泥方格育苗等。哪种方式好,我觉得应从棉苗素质、成本、投工三方面衡量。1979年我们做了试验,营养钵、方格苗用菜园土,塘泥方格育苗,因无塘泥,是用秧泥代替的。三种育苗方式都分别加入10%的火粪、10%腐熟的猪粪、0.2%的钙镁磷肥、4%的人粪尿。于3月25日播种。从三种方式的棉苗素质来看,最好的是营养钵育苗。棉苗主根长、侧根多,茎粗,叶面积大。其次是熟土方块育苗,最差是秧泥方格。从成本和投工来看,以熟土方块最好。省工、成本低。其次是秧泥方格育苗。营养钵育苗工本较高。综合来看,应以熟土方块育苗为主,营养钵、湖、塘泥,应因地制宜选用。
First, the nursery approach At present, the way of cotton seedling transplanting nutritious Bowl nursery, nurturing the square box nursery, ponds, squares and other ponds nursery. Which way is good, I think should be from the quality of cotton seedlings, cost, investment in three aspects of measurement. In 1979 we did the experiment, nutrition bowls, checkered garden soil, ponds square grid nursery, because there is no pond mud, is replaced with seedlings. Three kinds of breeding methods were added 10% of the fire manure, 10% maturity of pig manure, 0.2% of calcium magnesium phosphate, 4% of human waste. Sown on March 25. From the quality of cotton seedlings in three ways, the best is nutrition bowl nursery. Cotton seedling root length, lateral roots and more, stem thick, large leaf area. Followed by cooked potato nursery box, the worst is square griddle. From the cost and investment point of view, the best cooked rectangular box. Labor, low cost. Followed by seedlings square grid nursery. Nutritional bowl seedling higher this. Taken together, should be familiar with the nurturing of rectangular boxes, nutrition bowls, lakes, ponds, should be selected according to local conditions.
