一九七九年以来,我们探讨了矿质元素对水稻种子萌发及酶活性的影响,试验结果表明:矿质元素对促进种子萌发和培育壮秧都有良好的效应.为进一步探讨其增产效应及利用价值,在一九八一年,我们又进行了大面积和不同小区的重复试验,结果表明:尿素浸种四十亩大面积和不同小区四次重复试验,都较之清水对照有不同程度的增产效应,其中大面积试验比对照增产5·3%,小区试验比对照增产4·4%,其它微量元素浸种的分别增产2·6—3.2%。这种投资小(平均每亩所需费用不到一分钱)收效大,使用简便,易于操作的方法,对培育壮秧增加产量可以起到良好的作用.
Since 1979, we explored the effects of mineral elements on rice seed germination and enzyme activity, and the results showed that mineral elements had a good effect on promoting seed germination and seedling growth.In order to further explore its yield-increasing effect and utilization Value, in 1981, we conducted a large area and repeated plots of different plots, the results showed that: urea flooding forty acres of large area and four plots of different plots, compared with water control have different levels of yield The results showed that the large-area experiment increased yield by 5.3%, the plot experiment increased yield by 4.4% and the other micro-elements soaked by 2.6-3.2% respectively. This small investment (less than a penny per acre) is effective, easy to use and easy to operate, and can have a positive effect on nurturing strong seedling production.
