The Effects of Milk Vetch and Fertilizer Combined Application on the Growth and Yield of Rice

[Objective]The research aimed to study the effects of milk vetch and fertilizer on the growth and yield of rice under the rotate of milk vetch and rice.[Method] Early and late rice experiment were carried out.Each economic trait was measured,and its relationship with different fertilizer treatment was analysized,too.[Result]The results showed that the combined application of milk vetch and fertilizer not noly could improve the yield of rice,but also could reduce the dosage of fertilizer.On the basis of 40% fertilizer reduction,15 000 kg/hm2 milk vetch application had good effects on rice yield.[Conclusion] Milk vetch had significant residual effects on the following crops.
