随着农业学大寨运动的不断深入,农业生产水平迅速提高,种子的精选远跟不上飞跃发展的形势。目前大多数生产单位采用扬场或人工选种的办法,种子质量低,播种不精选种子,造成很大的损失和浪费。据黑龙江红兴隆农场管理局八五二农场试验,经精选后,可节约小麦8%、大豆9%、玉米11%。一般种子通过精选,亩产可提高约5%,节约和增产这两笔帐如推算到全国,则是一笔非常惊人的数字。
With the continuous deepening of the Dazhai Agricultural Movement, the level of agricultural production rose rapidly and the selection of seeds was far behind the rapid development. At present, most production units adopt the method of selecting seedlings or artificial selection, the quality of the seeds is low, and the seeds not sifted are sewn, resulting in great loss and waste. According to Heilongjiang Hung Hing Lung Farm Authority 852 farm trial, after selection, can save wheat 8%, soybean 9%, corn 11%. General seeds through the selection, per mu can increase about 5%, saving and increase these two accounts as projections to the country, it is a very alarming figure.
