【摘要】 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.更多还原

【Abstract】 We have been engaged in the study of effect of mineral elements on theseed budding of rice and enzymatic activities since 1979.And the results of our research are as follows:There is a good effect of mineral elements on the promotion or seed buddingand the brea ding of sturdy seeding of rice.In order to further probe into theutilization value of this research in increase of production.,we carried out repeatedexperiments on different areas,large and small,in 1981.The results show clearlythat seed soaking in urea can help increase the output by 4.4%.—5.3%.更多还原
