棉花育苗移栽就是当早春气温较低,大地还不能开犁播种的时候,就在具有增温和保暖设备的苗床里,提前播种育苗,待棉苗长到一定高度,大地气温升高,再把棉苗由苗床移栽到大田。这样,人为地加长了棉花的生育期,可使棉花早座桃、早开絮,增加霜前花,提高棉絮质量和单位面积产量。一、设置苗床:苗床选择背风向阳、排灌方便的生茬地,为了方便运苗,苗床应设在移 Cotton seedling transplanting is the early spring when the temperature is low, the earth can not plow sowing, seedling bed with warming and warm equipment, planting seedlings in advance, until the cotton seedlings grow to a certain height, the earth temperature increases, and then Cotton seedlings transplanted from the seedbed to the field. In this way, artificially lengthened the growth period of cotton, cotton early peach, early open floc, increase the frost before the flower, improve the quality of cotton and yield per unit area. First, the establishment of seedbed: seedbed selection leeward sunny, irrigation and drainage convenient stubble, in order to facilitate the transport of seedlings, seedbed should be located in the shift
