历年本所棉种粒选工作,都是我们工人用人工手选,每天一人只能选种约11斤,这样低的效率不但不适用于大量种籽的粒选,更不能适合将来我国集体化、机械化的要求,因此我们经常研究,如何利用现有的条件,使工作提高一步。我们曾作过数次试验,如用水漂、粘土拌水漂等,一直没有得到很好的结果,但我们并没有灰心,尤其经过了总路线的学习提高了我们工人的认识,大家都想找窍门提高工作效率。经我与王万忠等共同研究,试用扇车来作风选,结果成绩不错,在10公斤棉籽中选出不成熟及瘪籽1.3公斤,选后棉籽百粒重为13.02克,而淘汰的瘪籽百粒重仅9.68克。用扇车风选虽有一部分较重的坏籽不能选出,质量不及手选,但亦有一部分不成熟的棉籽,手选时看不出来,而在风选时却选出来了,因此若能在风选后再进行手选,则非但效率快,且质量也能更好。
In the past years, the cotton seed selection work of our institute was done manually by our workers. Only one kilogram of seed per day can be selected. This low efficiency not only does not apply to the selection of a large number of seeds, but also to the collectivization of our country in the future , Mechanization requirements, so we often study how to use the existing conditions to make the work one step further. We have conducted several tests such as water flooding and clay mixing. We have not been able to obtain very good results. However, we have not been discouraged. In particular, after studying the General Line, we have raised awareness of our workers and everyone has sought after tricks Improve work efficiency. After I and Wang Wanzhong and other joint research, try fan style selection, the results of good results in 10 kg of cottonseed selected immature and deflated seed 1.3 kg, after the election cottonseed hundred weight is 13.02 grams, and eliminate obscene seeds hundred The grain weight is only 9.68 grams. Although some of the heavier bad seeds can not be selected for fan-winnowing, the quality is not as good as that of hand selection. However, some immature cottonseeds are not visible in hand selection but are selected in wind selection. Can be hand-selected after the wind election, not only efficient, and the quality can be better.
