Title: Study on Effects of Raw Organic Matter Return and Crop Systems on Soil Environment
Abstract: Crop yields is comprehensive index of soil fortility. Crop yields had good correleation to soil organicmineral complex guantity (r=0.7032, t=4.53t0.01=2.83. Comparing simulated results with measured values showed that the raw organic matter return was correlated to soil organic matter, and showed that increase in soil organicmineral complex was correlated to in crement of soil organic matter (r=0.864, t=7.84t0.01=2.95), and increased the crop yields and improved soil organicmineral complex guantity. Return of green manure and wheat straw, rotation of crop and green manure, and intercropping of whead and green manure could improve soil organicmineral complex, soil physical progerty and activity of soil enzymes. It was an effective and feasible measure to maintain good soil environment and soil moisture. Soil organicmineral complex and activity of soil enzymes can be used as indicator for soil fertilitg and management of land at the same time.
