In order to study the effects of milk vetch on the yield,dry matter accumulation and photosynthetic characteristics of early rice in two different types of soils,i.e.red and yellow mud and river sand mud,a field micro-zone simulation pond test was conducted for 5 consecutive years,the treatments were no fertilization(CK),milk vetch(GM),chemical fertilizer(F)and application of milk vetch and chemical fertilizer(F+GM).The results showed that milk vetch treatment increased the yield of early rice,especially in the red and yellow mud,F+GM had a better yield-increase effect,which was 10%higher than...
