甜菜种子采收正值高温、多雨季节,安排不好会降低种子产量与质量。因此,要抓住有利时机进行抢收,适期脱粒、晾晒和入库保管。1.收获时期:当田间单株甜菜上有30％的种球成熟、一块采种田50％以上的植株达到成熟时,就可以收获。成熟植株的表现特征是果皮呈黄色。2.收获方法:根据甜菜种子成熟情况,可分批分期收获。收获后每2～3株捆成一捆,每两捆对顶码成长堆(10捆左右),以便通风晾晒(地点可选在田间或场院内)。3.脱粒晾晒:收获后的甜菜种株,一般晾晒2～3天,当达到枝梢不断、种球易落时,可用人工摔打脱粒。脱粒后的种子应及时除去夹杂物,铺成薄层晾晒,以防种球变色发霉。种子晾干后装入麻袋,放在干燥风凉处暂时保管。
Beet seed harvest is at high temperatures, rainy seasons, poorly arranged will reduce seed yield and quality. Therefore, we must seize the favorable opportunity to rush to harvest, threshing, drying and storage. 1. Harvest period: when the field of individual beet 30% of the bulbs mature, a mining more than 50% of the plants mature, you can harvest. The performance characteristics of mature plants are yellow peel. 2 harvest methods: According to the beet seed maturity, can be staged harvest. After the harvest, every 2 to 3 strains are bundled into a bundle. Each bundle grows to the top of the yard (about ten bundles) for ventilation and drying (the place can be selected in the field or yard). 3. Threshing drying: Beet varieties after harvest, the general drying 2 to 3 days, when the branches reach the constant, easy to fall when the ball can be manually thrashing threshing. After threshing the seeds should be promptly removed inclusions, thin layer of drying, to prevent bulbs mildew discoloration. After the seeds are dried, they are put in sacks and kept in a cool, dry place for a while.
