及时测定高粱、玉米种子的含水量,对指导田间、场院的种子晾晒、脱粒及安全贮藏都有作用。我们从1978～1981年研究、试验了种子水分感观测定法。实践证明,用这种方法测定种子含水量,快速、准确,而且容易掌握。1.高粱的完熟粒和未完熟粒(青秕粒),用牙齿咬有喀喀的响声,同时能掉出较多的高粱碎粉面,种子的含水量一般在12～13.5％。2.高粱的完熟粒和未完熟粒用牙齿咬有喀喀的响声,并同时掉出少量高粱碎粉面,或高粱穗上的籽粒成熟饱满,穗颈秸秆用手一折就断,并有喀喀的响声,同时还掉出一些秸秆瓤的碎末,种子的含水量一般在14～14.8％。
Timely determination of sorghum, corn seed moisture content, to guide the field, field hospital seed drying, threshing and safe storage have a role. From 1978 to 1981, we studied and tested the seed moisture sensitometry. Practice has proved that this method of determination of seed moisture content, fast, accurate, and easy to grasp. 1. The sorghum’s grains and unripe kernels (barley kernels) can be snapped with Titicaca teeth, while more sorghum flour can fall off. The moisture content of the seeds is generally 12-13.5%. 2. Sorghum mature grains and immature grains biting Titicuqi teeth, and at the same time fell out a small amount of sorghum flour surface, or sorghum grains on the full maturity of the ear, neck and neck with a broken hand off, and there Titicaca noise, but also fall out of some straw 瓤 crushed end, the seeds of the water content is generally 14 ~ 14.8%.
