为了夺取晚稻高产,必须采取切实有效的措施,把晚稻种子贮藏好。在晚稻种子贮藏中应注意如下几点: 1.要求种子成熟度高,青粒少,完整无损,无病虫,谷粒饱满。种子收获后必须抢晴晒干、扬净,种子含水量为籼稻不高于13.5%,粳稻不高于14.5%,杂质不高于1.5%。如果没有水分测定器可用牙咬或手测,牙咬声响大,种谷断而不碎,或者手摸沙沙响,用手插入种子堆内,阻力很小,易伸进底层,说明种子已干燥,反之,牙咬不发声,一咬即碎,手不易伸进种子堆内,抽出来又有些种子附着在手上,这说明种子未干,必须重晒。 2.要有专门贮藏保管种子的仓库和必要的设备。种子必须在干燥、低温密闭条件下贮藏,这样
In order to seize late rice high yield, we must take effective measures to store late rice seeds. In late rice seed storage should pay attention to the following points: 1. Requires high maturity of seed, less green, intact, no pests, full of grains. Seeds must be grabbed and sun-dried after harvest. The water content of seed is not higher than 13.5% for indica rice, not higher than 14.5% for japonica rice and not higher than 1.5% for japonica rice. If there is no hydrometer available dental bite or hand measurement, teeth bite loud, kind of broken off the valley, or hand touch rustle, hand inserted into the seed pile, the resistance is small, easy to reach the bottom, indicating that the seeds have dried On the contrary, the teeth bite does not sound, a bite that is broken, the hand is not easy to reach into the pile of seeds, pulled out and some seeds attached to the hands, indicating that the seeds have not dried, you must re-drying. 2. There should be a special storage and storage of seed storage and necessary equipment. Seeds must be stored in a dry, low temperature closed condition, so
