抗虫棉的种植方法与普通棉花基本相同,但有五点在种植时应引起棉农的注意 1.合理施肥 抗虫棉苗期和中期生长相对缓慢,结铃集中于中后期,容易导致后期早衰,所以施肥原则应是施足有机肥,增施磷钾肥,重施花铃肥,补施盖顶肥,喷施叶面肥。基肥施用量要高于普通棉花的1～2倍,特别要重施钾肥,抗虫棉对钾肥特别敏感,缺钾会导致抗虫棉后期过早枯萎。
Insect-resistant cotton planting methods and ordinary cotton is basically the same, but there are five points in the planting should attract the attention of farmers 1. Pro-fertilization of cotton seedling and mid-term relative growth is relatively slow, the bell concentrated in the late, easily lead to premature aging Therefore, the principle of fertilization should be applied enough organic fertilizer, increased phosphorus and potassium fertilizer, re-applied flower bell fertilizer, top-dressing fertilizer, spraying foliar fertilizer. Base fertilizer application rate should be 1 to 2 times higher than that of ordinary cotton, especially to re-application of potash, pest-resistant cotton is particularly sensitive to potash, potassium deficiency will lead to premature wilt Bombyx mori.
