Cotton belongs to many crops and it takes about 60 days from the start of harvesting (initial period of boll opening) to the end of harvesting. There are several issues to be aware of when harvesting cotton throughout the harvest period:
First, timely picking. After cotton bolls, it is usually picked every 5-7 days. Picking is too early, cotton fiber has not yet fully matured, and yield and quality have been reduced. When picking is too late, the cotton wadding will be weakened by the wind and sun exposure, which will reduce the fiber tension, color pollution, and will also reduce the quality of cotton. To achieve fine collection and fine collection, improve the quality and grade of cotton fiber.
Second, prevent rain. After the mature cotton wool is exposed to rain, the pigments of the cotton husk, cotton leaf, and eucalyptus leaf will contaminate the cotton fiber, causing spotting of the cotton fiber and the like, as well as causing mildew and deterioration. Therefore, we must keep abreast of the weather changes, pay attention to the weather forecast, and grab the cotton before the rain. In case of prolonged rain and continuous weather, the boll opening cracking is slow or the boll opening is not normal, the old boiled cotton should be picked, heated and dried in the room to promote ripening and cracking.
Third, do a good job of "four points", "four nets", "six without". "Quadruple" refers to picking cotton, picking fine flowers, buckwheat cotton, and floor cotton, extracting it separately, and drying it separately, storing them separately, and not mixing them together so that they can be sold in different grades. "Four nets" refers to cotton husks when picked.æŽ æŽ , , , , , , , , , , , , , 棉 棉 棉 棉 棉 棉 棉 棉 棉 棉 棉 棉 棉 棉 棉 è½ è½ è½ è½ è½ è½ è½ è½ è½ è½ è½ è½ è½ è½ , , , , , “ “ “ å…Silk, without chemical fiber products, animal hair, and sundries. In the drying of cotton, avoid drying on the cement floor and drying mats. Breathable bamboo curtains and bamboo rafts should be used to separate the sun from the grade to ensure the quality of the cotton.
Fourth, in the seed cotton to prevent "three wires" mixed. In order to ensure the quality of seed cotton and increase the income of cotton farmers, the following measures should be taken when picking cotton: 1 The cotton pickers should wear white cotton caps to prevent human hair from accidentally falling into the seed cotton. 2 The seed cotton bag used by the picking workers shall be made of pure cotton white cloth. 3 When drying seed cotton, try to keep away from villages and poultry. 4 When the cotton is sold for sale, the motor vehicle is used for transportation and the packaging materials use pure cotton white cloth.
