Study on the Effects of Belt-like Compound Planting of Soybean and Corn and Soil Improvement on Soybean in Saline-alkali Soil
In order to study the effects of different fertilization treatments on the growth,yield and quality of soybean and the nutrient content of soil in the process of belt-shaped compound planting of soybean and maize in saline-alkali soil,it can be used as a reference for rational fertilization and application of fertilizer on belt compound planting of soybean and corn,in the base of Shilixiang Sesame Products Co.,Ltd..In Wudi County,Binzhou City,Shandong province,we carried out the"Soybean and corn belt compound planting-soil improvement experiment of saline-alkali soil".The results showed that the biological characteristics and yield of soybean were improved by applying humic acid controlled-release fertilizer and Soil conditioner fertilizer in the belt-type compound cropping system,the content of soil organic matter increased,the content of soil EC and water-soluble salt decreased.The dry weight of aboveground part increased by 33.78%,100-seed weight increased by 9.16%,the number of rhizobia per plant increased by 6,and the yield increased by 20.38%.Soil EC decreased by 48.7 US/CM and total soluble salt decreased by 0.35 g/kg.It is suggested that farmers in saline-alkali land could adopt soybean-maize belt compound planting,apply humic acid controlled-release fertilizer and Soil conditioner rationally,and increase soybean yield to obtain more benefits.
