我国北方棉区春季寒流频繁,棉花播种后,常因寒流影响,难保全苗、壮苗;秋季气温下降较快,秋桃常因积温不足,铃轻、产量低、品质差,如遇早霜,则表现更为突出;惟有伏桃能充分成熟,桃大、品质又好。只是由于伏天阴雨多、光照少,伏桃容易脱落。我所培育的早热品种中棉所10号,适于夏播,能和小麦一年两熟,受到群众欢迎。但由于 China’s northern cotton spring cold frequent, cotton sowing, often due to the influence of the cold, it is difficult to protect the whole seedlings, strong seedlings; autumn temperatures fall quickly, often due to lack of autumn temperature, bell light, low yield, poor quality, The performance is more prominent; only V satisfied full maturity, Peach, good quality. Just because of overcast rainy days, less light, V peach easily fall off. I cultivate the hot varieties of cotton in the No. 10, suitable for summer sowing, wheat and wheat can be cooked twice a year, welcomed by the masses. But thanks
