杂交稻种子贮藏时间长,从夏、秋季制种,分别为9月中旬和10月中旬收获,直至翌年6月中、下旬播种,贮藏时间为240-270天。种子贮藏保管的好坏,直接关系到明年的种子发芽率和种植面积落实。为此,农户在冬贮杂交稻种子要注意以下“十忌”: 一忌烈日下曝晒种子。高水分种子不能在中午烈日下曝晒,以免种子“爆腰”,影响发芽率。 二忌种子含水量过高。杂交稻种子安全贮藏水分标准为 Hybrid rice seeds are stored for a long time and are planted in summer and autumn. They are harvested in mid-September and mid-October, respectively, and are sown in the middle and late June of the next year with a storage time of 240-270 days. The quality of seed storage and storage is directly related to the seed germination rate and planted area for next year. To this end, farmers in winter hybrid rice seed paddy should pay attention to the following “ten bogey”: a bogey sun exposure seeds. High moisture seeds can not be exposed to the sun at noon, so as to avoid the seeds “burst waist”, affecting the germination rate. Second, avoid high water content of seeds.
