未成熟的棉铃脱落现象是棉花生长习性的一种特征,据估计,由于花蕾和幼铃的早期脱落,棉花的潜在产量可能损失高达70％。虽然棉铃的自然脱离过程还不完全了解,但很明显环境条件可能是起主要作用。早期的研究证明,当植株的含水量低,土壤的含水量低和蒸发率高的情况下,棉铃的脱落就增加了。近期的研究证明,当大田土壤水位在 Immature cotton boll shedding is a feature of cotton growth habit and it is estimated that the potential yield of cotton may be as high as 70% due to early shedding of buds and young bellies. Although the natural detachment of cotton bolls is not fully understood, it is clear that environmental conditions may play a major role. Earlier studies have shown that the shedding of cotton bolls increases when plants have low water content, low soil water content and high evaporation rates. Recent studies have shown that when the field soil water level in
