    摘要:

    为研究翻压紫云英对2种不同类型土壤早稻产量、干物质积累及光合特性的影响,采用连续5年田间微区模拟池试验,各处理为不施肥(CK)、单施紫云英(GM)、纯化肥(F)及紫云英配施化肥(F+GM),2种类型土壤分别为红黄泥与河沙泥。结果表明:翻压紫云英可使早稻增产,尤其在红黄泥中F+GM的增产效果更好,比F增产10%;2种土壤中,F+GM与F相比稻草产量差异不显著(P>0.05)。与CK相比,2种土壤的F+GM与GM可促进早稻生长前期各营养器官(根、茎叶)干物质的增加,后期F+GM与GM营养器官的干物质不再增加而有所降低;F+GM和GM的水稻籽粒干物质比CK高,而且持续增加。翻压紫云英可改善早稻的光合特性,2种土壤F+GM的SPAD值、净光合速率、气孔导度最高,胞间CO2浓度除了河沙泥灌浆期高于GM外,其余均为最低。在2种土壤中表现出类似趋势,紫云英配施化肥可以增强早稻光合能力,增加干物质量,进而实现早稻

    Abstract:

    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 that of F. In the two soils,the rice straw yield of F+GM had no difference compared with that of F. Compared with CK,the dry matters of various vegetative organs(roots,stems and leaves)in the early stage of early rice growth of the F+GM and GM of the two soils were promoted,and but they no longer increased in the later stage and showed a decrease trend. The dry matter of rice grains of F+GM and GM was higher than that of CK,and it continued to increase. Milk vetch application improved the photosynthetic characteristics of early rice. The SPAD value,net photosynthetic rate,and stomatal conductance of the rice of F+GM in the two soils were the highest,and the intercellular CO2 concentration was also the lowest except it was higher than that of GM in the filling period in the river sand mud. It showed similar trends in the two soils,milk vetch combined with chemical fertilizers can enhance the photosynthetic capacity of early rice,increase the dry matter quality,and thus increase the yield of early rice.
