1.贮藏前曝晒:棉种入库前要连续曝晒3～5天,使其充分干燥,据测定,棉种含水量20%,存放2～3个月发芽能力就大幅度下降;含水量11%,贮存到次年播种仍能保证较高的发芽率,可见贮存棉种必须降低含水量,一般通过曝晒降至10%左右为宜。2.透气包装。棉种贮存期间,生理活动仍在进行,为保证其正常呼吸和代谢活动进行,宜采用透气 1. Pre-storage exposure: cotton seed storage before exposure to continuous 3 to 5 days to fully dry, it was determined that the cotton seed moisture content of 20%, stored 2 to 3 months significantly reduced the germination capacity; water content of 11 %, Stored until the following year sowing can still guarantee a higher germination rate, visible storage of cotton species must reduce the water content, generally reduced by exposure to about 10% is appropriate. 2. Breathable packaging. Cotton species stored during the physiological activity is still in progress, in order to ensure its normal breathing and metabolic activity, should adopt a breathable
