1956年春天,我曾经领导卡梅士林师范学校的学生进行了各种肥料对玉蜀黍产量的作用和效力的实验。莫洛托夫集体农庄管理处为了做这个实验拨出四公顷的土地。这块地是1955年秋天耕过,1956年春天播过春小麦的平坦高地。土壤是弱淋溶性黑土。为了进行实验,我们把这块地划分为几个小区。5月11—12日运来了全部肥料,用手工把肥料施到地里,并进行了耘地复土。在1号小区里按每公顷350公斤计算施了过磷酸石灰;在2号小区里按每公顷400公斤计算施了灰肥;在3号小区里按每公顷400公斤计算施了鸟粪;在4号小区里按每公顷200公斤过磷酸石灰和5000公斤腐殖质计算施了有机矿物肥料;第5号小区没有施肥,是对照用地。我们就这样来考查矿物肥料、有机矿物肥料和有机肥料的作用。学生们直接参加了准备播种用的种子、脱粒、分组挑选、用谷仁乐仁(一种农药)拌种进行种子消毒和用撒粉器撒布
In the spring of 1956, I used to lead students at Camelling Normal School to conduct experiments on the effect and effectiveness of various fertilizers on maize yield. Molotov Collective Farm Management allocated four hectares of land for the experiment. This land was tilled flat in the autumn of 1955 and sowed in spring in spring of 1956. The soil is weakly leached black soil. In order to experiment, we divide this land into several districts. May 11-12 shipped all the fertilizer, the fertilizer applied to the ground by hand, and carried out the earth. Calcium phosphate was applied at a rate of 350 kg per hectare in plot 1; gray manure was calculated at plot 2 in an area of 400 kg per hectare; guano was calculated at plot 400 kg per hectare in plot 3; Area 4, according to 200 kg per hectare perphosphate lime and 5000 kg of humus calculation applied organic mineral fertilizer; No. 5 no fertilization plot, is the control of land. We examine the role of mineral fertilizers, organic mineral fertilizers and organic fertilizers in this way. The students took part directly in the preparation of seeds for sowing, threshing, grouping, seed disinfection with seed dressing of Kurehanlei (a pesticide) and sprinkling with a duster
