看准收花的时期:棉铃由下而上、由内而外逐渐成熟开絮,3～4天后,纤维和种子才能完全成熟,所以收花不能过早或过晚。收早了,不仅难摘费工,而且籽棉的含水量高,贮藏期间易霉变;收晚了,籽棉会被风雨吹淋到地上,泥污霉烂,降低纤维强度和品质。大部分棉株有一两个棉铃开絮,就应收花,每隔7～10天采收一次,最好在上午露水干时开始到傍晚棉絮发潮时停止。雨季应在雨前收花,避免遇雨造成损失。
Spotted the period of income: Cotton bolls bottom-up, gradually mature from the inside opened open floc, 3 to 4 days after the fiber and seeds can be fully mature, so the income can not be too early or too late. Early harvest, not only difficult to pick fees, but the high moisture content of seed cotton, easy to mildew during storage; late harvest, the seed cotton will be blown to the ground with wind and rain, mud rot, reducing fiber strength and quality. Most cotton plants have one or two cotton bolls open the floc, they should receive flowers, collected once every 7 to 10 days, it is best to dry dew in the morning when it starts to stop the tide in the evening tide. Rainy season should receive flowers before the rain, to avoid the loss caused by rain.
