摘要： 密度对新海14的生育进程、铃重和衣分率影响不大，但对它的株高、叶片数及蕾、铃的脱落数影响较大，即随着密度的增加株高降低，叶片数减少，蕾、铃的脱落率增高，并且铃的脱落大于蕾的脱落；对有效铃数和吐絮数影响也较大。结果表明新海14在南疆可实行高密度种植，适宜的种植密度应为27株/hm2左右。

Abstract: Density has less effection on the growth period, bolls weight and gin turnout except the height ,leaves number,shedding rate of buds and bolls, number of effective bolls and wadding,Which is that, as the density of Xinhai 14 increase, the height get short, leaves number reduce, shedding rate of bolls increase.And shedding rate of bolls is more than buds.The results of the test showed that the suitable density is around 270,000/hm2 in south Xinjiang.
