培育早熟棉花品种,实行棉油两熟或粮油两熟,可以充分利用自然资源,提高复种指数,促进粮棉油全面增产.棉花适当晚播,在高温条件下生长发育快,光合效率高,其结铃盛期在8月上、中旬,虽无伏前桃,但伏桃和秋桃多,产量稳,同时,棉花生育期短,可减少棉田投资投工,降低成本.河南7602就是适于两熟栽培的新品种.
By cultivating precocious varieties of cotton and implementing double ripening of cottonseed or double ripening of grain and oil, we can make full use of natural resources, improve the multiple cropping index and promote the comprehensive yield increase of grain and cottonseed.The cotton is suitable for late sowing, grows fast at high temperature and has high photosynthetic efficiency Knot boom in August, mid-term, although no pre-V Peach, but the peach and autumn peach, yield stable, at the same time, cotton growth period is short, can reduce investment in cotton fields, reduce costs. Henan 7602 is suitable for two Cooked new varieties.
