2000年4月1日国家实施粮食质量新标准,新增加精米率指标。新标准规定,稻谷以出糙率和整精米率两项指标分等定级。整精米率的最低指标是50％,低于最低指标的粮食定为等外粮,由粮食部门按照“购得进、销得出”的原则收购。这样整精米率就对稻谷能否卖得出去,能否卖个好价钱起很大作用。 On April 1, 2000, the state implemented the new food quality standards and added new indicators of increasing the rate of polished rice. The new standard stipulates that rice should be graded according to two indicators of roughness and precision of polished rice. The lowest index of the whole milled rice rate is 50%, and the grain below the minimum index is defined as the extra-staple food, which is acquired by the grain department in accordance with the principle of “purchase proceeds and sales proceeds”. This whole milled rice rate will be able to sell rice, can sell a good price play a big role.
