棉花具有无限生长的习性,在无霜期较长的长江中下游棉区,多出现植株高大,果节数多,但落蕾落铃较多,成铃较少,单铃重较轻,从而影响了棉花产量的提高。为探讨减少棉花蕾铃脱落的问题。1984年我所开展了棉花稀植大棵优质高产栽培的研究,以期降低棉花蕾铃脱落,提高铃重和纤维品质。 The cotton has the habit of unlimited growth. In the middle and lower reaches of the Yangtze River where the frost-free period is long, more plants are tall with more fruit nodes. However, there are more fall and fall rings, fewer bells and lighter single bolls, Cotton production increased. In order to explore to reduce cotton buds off the issue. In 1984, I conducted a study on high quality and high yield cultivation of large cotton sprouts with a view to reducing cotton boll drop off, improving boll weight and fiber quality.
