“一个正确的认识,往往需要经过由物质到精神,由精神到物质,即由实践到认识,由认识到实践这样多次的反复,才能够完成”。革新棉花栽培方法,采用扩大行距,适当放稀密度,营养钵育苗移栽和插种冬、夏绿肥的栽培方法,有利于改善棉田通风透光条件,缓和营养生长与生殖生长的矛盾,经济有效地利用光能,较多地将太阳能转化为化学能,延长有效结铃期,提高结铃率,充分发挥棉花单株的生产潜力,是一种夺取棉花高产的有效途径。然而,由于这种 “A correct understanding, often need to go through the material to the spirit, from the spirit to the material, that is, from practice to understanding, through the practice of repeated so many times to complete ”. Innovative cotton cultivation methods, the use of expanded row spacing, appropriate dilution of density, transplanting of nutrition bowls and transplanting seedlings and summer and summer green manure cultivation methods are conducive to improving cotton ventilation and light conditions, ease the conflict between vegetative and reproductive growth, and cost-effective It is an effective way to seize the high yield of cotton by using solar energy to convert more solar energy into chemical energy, to extend the effective bolting period, to increase the boll rate and to give full play to the production potential of cotton plants. However, due to this
