近几年来,我省机械精选种子工作发展较快。全省的种子精选机从1978年的30台发展到现在的1900多台;种子精选量由1978年的几十万斤增加到4.5亿斤。如以每亩(亩产600斤)增产5%计算,全省已推广机选播种田2000万亩,可增产粮食5亿多斤。过去每亩播量为30斤,以每亩节约用种量20%计算,可节约种子1亿多斤。我省机械精选种子所以能发展这样快,主要的原因是我们在全省范围内进行了机械精选种子与未精选种子、精选后的不同播种量的对比试验,取得了大量的科学数据;并采用各种形式向农村广大干部、社员宣传机械精选种子的好处,群众明白了精选的优点,自觉要求机械选种。
In recent years, our province machinery selection of seeds work faster. The province’s seed sorting machine has grown from 30 in 1978 to more than 1900 now; the selection of seeds has increased from several hundred thousand jin in 1978 to 450 million jin. For example, the yield increase of 5% per acre (600 kg per mu) is calculated. The province has promoted 20 million mu of machine-aired sowing crops and can increase grain output by 500 million kilos. In the past, the acreage per mu was 30 pounds, which was saved by 20% per acre, which saved over 100 million kilos of seeds. The main reason why we can develop such a fast machinery in our province is that we have carried out comparative tests on different sowing amounts of mechanically-selected seeds and unselected seeds across the province and made a great deal of science Data; and various forms of rural cadres and members to promote the benefits of mechanical selection of seeds, the masses understand the advantages of selection, conscientiously require mechanical selection.
