种子加工业在我国是一门新兴工业。种子机械加工是农业生产的重要环节。又是提高种子质量、实现种子标准化、确保播种质量,夺取稳产高产的重要手段。一般大田里生产的原种只有经过先进的机械设备进行脱粒、烘干、清选、拌药等一系列加工过程,才能成为合格的优良种子。为什么要对种子进行加工呢?这是因为收获的种子中大部份是饱满的成熟好的,但经常混有因机械脱粒造成的破碎粒、在生长过程中有缺陷或遭虫蛀而未成熟的,混入的砂石、尘土,糠壳杂质;其它作物的种子和同种怍物不同品种的种子及杂草的种子混杂;就是同一品 Seed processing industry in our country is a new industry. Seeds machining is an important part of agricultural production. It is also an important means to improve seed quality, standardize seeds, ensure sowing quality and win steady and high yield. In general, the original seeds produced in the field can be qualified as excellent seeds only after a series of processing processes such as threshing, drying, cleaning, mixing and the like through advanced machinery and equipment. Why seed processing? This is because most of the harvested seeds are full and mature, but often mixed with broken kernels caused by mechanical threshing, are defective in growth or are unripe by insects Mixed with sand and gravel, dust, chaff shell impurities; seeds of other crops and seeds of the same species of different varieties of seeds and weeds mixed; is the same product
