棉花发育受水分和营养的影响棉花在最佳水分和营养条件下，容易发生旺长。喷施植物生长调节剂ＭＣ（棉宝）能减缓棉株营养生长，促进早熟，但对产量的影响有增产也有减产，常归因于环境与品种的不同。美国的试验表明，用ＭＣ处理后棉花株高降低，主茎节间数减少。土壤水胁...
Cotton development is affected by water and nutrition cotton in the best moisture and nutrient conditions, prone to flourishing. Spraying plant growth regulator MC (cotton boll) can slow the vegetative growth of cotton plants and promote the early maturity. However, the effects of yield increase and yield reduction are often attributed to different environments and varieties. U.S. tests showed that the plant height of cotton decreased and the number of main stems decreased after treatment with MC. Soil water stress ...
