塑膜营养钵育苗移栽棉花是克服早春低温,实现早播早育苗,缩短套作棉共生期,延长麦后棉生育期,解决两熟矛盾,充分利用棉花有效生长季节和延长有效开花结铃期,夺取棉花高产稳产的一项重要技术措施。育苗移栽棉一般比直播棉增产20～30%。塑膜育苗移栽棉之所以早发早熟,这与播种以后覆盖透光率大和不透气性的塑膜有关。塑膜具有增温保温保湿性能,利用日光能转化成热能,提高床内日均温,促使棉子
Plastic film nutrition Bowl nursery transplanting cotton is to overcome the low temperature in early spring, to achieve early sowing early nursery, shorten cotton intercropping period, extend wheat growth period, to resolve the conflict between the two to make full use of effective cotton growing season and extend the effective flowering knot Period, an important technical measure to seize the high and stable yield of cotton. Transplanting cotton seedlings generally increased cotton yield 20% to 30%. The reason why plastic film seedling transplanting cotton early premature, which is covered after sowing with large transmittance and airtight plastic film. Plastic film with warming moisturizing properties, the use of solar energy into heat, increase the average daily bed temperature, prompting cotton
