摘早蕾是一项新技术,科学合理地应用可以提高产量和改善品质。据在高产棉田试验,摘早蕾一般可增产皮棉10%~15%,霜前花率提高5%~10%。摘早蕾有两大好处。一是摘早蕾能促进营养生长,较好地建立起高光效的生产结构,协调好营养生长与生殖生长的关系,在最佳结铃期转换代谢类型,使碳、氮代谢两
Picked early bud is a new technology, scientific and rational application can increase production and improve quality. According to the high-yielding cotton field experiment, picking cotton buds generally can increase lint yield by 10% ~ 15% and frost bloom rate by 5% ~ 10%. Picked early bud has two major benefits. First, picking up early buds can promote vegetative growth, establish a high light-efficient production structure, coordinate the relationship between vegetative growth and reproductive growth, and change the types of metabolism during the optimal boll transition period, so that carbon and nitrogen metabolism two
