我们于五年之内(1947——1951)在莫斯科省米褐聂夫斯克区“红色战士”集体农庄和全苏肥料农业技术土壤科学研究所中央试验站的田地上进行了斜地土壤营养和水份状况的研究及片蚀量的计算,证明坡地土壤具有明显不同的农业特性。“红色战士”集体农庄土壤调查的结果确定全耕地面积68.6%土壤是在1°24’——3°24’的斜坡上。根据灰化度和片蚀度来划分土壤:(1)生草强灰化土——22.5%;(2)暂时高湿润的生草强灰化土—8.9%;(3)弱和中度片蚀的生草强灰化土—46.6%;
In less than five years (1947-1951) we conducted sloping soil nutrition in the fields of the “Red Warrior” Collective Farm in the Mecnirovsk region of Moscow Province and the Central Experimental Station of the Soochow Fertilizer Institute of Agricultural Technology Soil Science and The study of water status and the calculation of sheet erosion have proved that the slope soil has obviously different agricultural characteristics. As a result of the “Red Warrior” Collective Farm Soil Survey, 68.6% of the total area of the soil was found on slopes of 1 ° 24 ’- 3 ° 24’. According to the degree of ashing and earthen erosion of the division of the soil: (1) Grassland strong ash soil - 22.5%; (2) Temporarily high humidity of grass grass intensive ash soil -8.9%; (3) weak and moderate Erosion of the grass grass ash intensive soil -46.6%;
