关于深耕促进淤土熟化和对大豆作物增产效果,已于1959年作了试验,初步肯定了豆地适宜的耕作深度,及其对底土熟化作用。为继续弄清大豆于沈阳地区淤土上的适宜耕作深度,和进一步摸索深耕与施肥对改善土壤理化及生物特性等关系,1960年又于沈抚公路南浑河冲积平原上的淤土上继续进行试验,现将其结果整理如下,请批评指正。
On deep plowing to promote silt maturation and soybean yield increase effect, has been tested in 1959, initially affirmed the suitable depth of bean cultivation, and its effect on the subsoil. In order to continue to understand the suitable cultivation depth of soybean in silt in Shenyang area and further explore the relationship between deep plowing and fertilization to improve the soil physical and chemical properties and biological characteristics, it was continued in silt on the alluvial plain of south Hunhe River of Shen-Fu Highway in 1960 To test, now the results are organized as follows, please correct me criticism.
