1.适时收获,及时干燥。收割期间的气候是影响杂交稻种子贮藏品质和贮藏稳定性的重要因素之一。收获期间遇上阴雨,杂交稻种子在植株上萌动发芽,降低贮藏品质。在晴朗天气下,抢收抢割,减少种子在植株上萌动。同时收割时注意杂交稻种子成熟度,收获过早,种子未充分成熟,饱满度差,呼吸强度大;收获过迟,增加种子萌动机率,加重稻壳颖枯病,因而要适时收获,掌握在完熟期立即开镰收获。种子收获脱粒后,及时晒种,降低种子水分。一般刚收获种子含水量在18～ 1. Harvest timely, timely drying. Climate during harvest is one of the important factors affecting the storage quality and storage stability of hybrid rice seeds. During the rainy season, the hybrid rice seeds germinate on the plants and reduce the storage quality. In fine weather, grab the harvest, reduce seed germination on the plant. At the same time pay attention to harvest hybrid rice seed maturity, premature harvest, the seed is not fully mature, plumpness, respiratory intensity; harvest too late, increase the chance of seed germination, increase the rice husk blight, which should be timely harvest, Maturity immediately opened sickle harvest. Seeds harvest threshing, timely basal, reduce seed moisture. Generally just harvested seed moisture content 18 ~
