为了促进油菜壮苗早发,春后高产,我们试用三种种子处理方法:(1)种子裹肥:先将每斤种子掺入50克化学浆糊或等量河泥,加以搅拌,使种子互不叠集。再以2两过磷酸钙,1.5两硫铵,1斤干细土的比例拌成混合肥土。然后把上述种子掺入混合肥土中,充分搅动,使每粒种子表皮都裹上一层肥土。(2)高锰酸钾浸种:以2000ppm高锰酸钾液浸种4天,捞出的种子无需冲洗,以便观察。(3)过磷酸钙液浸种:以15:500的过磷酸钙澄清水溶液浸种2天。供试品种为本场选育的“五四大粒早”,9月20日播种,11月14日移栽,小区面积4平方米,随机排列,重复3次。结果如下:
In order to promote early seedling strong seedlings, high yield after spring, we try three kinds of seed treatment methods: (1) seed wrapping: first per kilogram of seeds mixed with 50 grams of chemical paste or equal amount of river mud, stirring, so that seeds Not overlap each other. And then two over two calcium phosphate, 1.5 two ammonium sulfate, 1 kg dry fine soil mixing ratio of mixed fertilizer. Then the above seeds into the mixed soil, stir, so that each seed is covered with a layer of fat soil. (2) Potassium permanganate soaking: 2000ppm potassium permanganate soaking seed 4 days, remove the seeds without washing, in order to observe. (3) superphosphate solution soaking: 15: 500 supernatant clarified aqueous solution soaking 2 days. The test varieties for the field selection of “May 4 grain early,” sown on September 20, November 14 transplanting, the plot area of 4 square meters, randomly arranged, repeated 3 times. The result is as follows:
