- Abstract:
- Continuous cropping of soybean has caused soil nutrient imbalance, decrease of enzyme activity, increased soybean diseases and reduced yield and quality. Using field plot test method, we analyzed the effects of soil displacement, soybean seed measures on enzyme activity and the root rot disease index in different soil layers, and eliminated the soybean continuous cropping obstacle to provide the technical support of science. The main results were as follows. Soil replacement, increasing application of phosphate fertilizer or organic fertilizer and soybean seed measures can improve the soil urease activity, invertase activity and phosphatase activity of soybean field. Compared with the control, the activities of urease in T2,T3,T4 treatment increased from 0 to 10 cm soil layer. Soil replacement and increasing application of organic fertilizer can improved the activity of invertase in soil. Soil replacement, increasing application of phosphate fertilizer or organic fertilizer and soybean seed can effectively maintain the activity of phosphatase in soybean soil and reduce the disease index of soybean root rot. Soil replacement, increasing application of phosphate fertilizer can significantly promote the soybean production, the soybean yield increased by 20.42% compared with CK.
