由于用途和目的不同,我国目前计算甜菜产量习惯上有三种方法,即工业产量、农业产量和生物产量。现在我们经常讲的工业产量,实际上就是糖厂的收购数量,并以此数字上报管理部门,定为当年甜菜产量,若以该总产量被播种面积除,即为单位面积产量。其实这种计算方法并不能体现甜菜产量的真实情况。因为糖农种植甜菜起收以后,往往有一部分块根自己留上加工成糖浆自食自用,或者做为饲料喂猪、牛、羊,这一部分不在收购数量之内。另外糖厂在收购甜菜时都要扣杂,一般是2—7％,特殊情况还要高一些。甜菜和粮食、油料等作物不一样,以粮食为例,一部分做为公粮上缴国家,其余在政策允许范围内自己出售一部分,还要
Due to different purposes and purposes, there are currently three methods for calculating sugar beet yield in our country: industrial output, agricultural output and biological output. Now, what we often say about industrial output is actually the quantity acquired by the sugar factories and is reported to the authorities as the beet yield in that year. If the acreage is divided by the total output, it is the yield per unit area. In fact, this calculation method does not reflect the real situation of sugar beet production. Because the sugar beet grow sugar beet since the harvest, often part of the root to stay processed into syrup for their own use, or as a feed to pigs, cattle, sheep, this part is not within the acquisition amount. In addition the sugar beet in the acquisition of buckets should be mixed, usually 2-7%, but also higher in special cases. Beet and grain, oil and other crops are not the same, with food, for example, some as a public food turned over to the state, the rest allowed to sell their own part of the policy, but also
