棉花花蕾的脱落(幼蕾脱落),在过去20年里已经受到很大注意。失去花蕾,就会失去产量。多年来,原因不明的过量花蕾脱落导致棉花减产,引起了争论。通过调查和剖析,揭示了导致花蕾脱落的原因和症状;使我们了解了:由于昆虫造成的损伤使花蕾脱落的时期和位置,并且由此可以得出关于花蕾脱落对产量影响的某些结论。要充分了解花蕾脱落问题,就必须了解棉花植株的开花习性。棉花的生长与多年生的灌木相似;棉花主干的末端花蕾和有生长力的棉枝继续长出叶子和梗,直到水份、养分或温度等生长因素困难,使其休止。花蕾、花和棉桃在果枝上的叶丫里长出来。 The shedding of cotton buds (baby buds shedding) has received a great deal of attention over the past two decades. Lost bud, it will lose production. Over the years, the loss of excess buds of unknown cause led to a decrease in cotton production, causing controversy. Through investigation and analysis, the causes and symptoms of flower buds shedding were revealed. We learned about the period and location of flower buds shedding due to the damage caused by insects, and from this we can draw some conclusions about the effects of flower bud shedding on yield. To fully understand the problem of flower buds off, we must understand the flowering habits of cotton plants. The growth of cotton is similar to that of perennial shrubs; the end buds and vegetative shoots of the cotton trunk continue to grow leaves and stems until their growth factors, such as moisture, nutrients or temperature, become dormant. Buds, flowers, and peaches grow in leaves on the branches.
