长期施肥对大豆生长状况及产量的影响
Effect of Long-term Fertilization on Growth and Yield of Soybean
摘要
Abstract
To study the effect of long-term fertilization on growth and yield of soybean, a field experiment was conducted for twenty-seven years in Hailun Agricultural Ecology Station of Chinese Academy of Sciences. The results indicated that long-term application of organic manure could significantly increase plant height and the number of pod,with high growth rate. More nod-ulation(both the number and biomass)were observed in the plots received NPK,but both of these were not significant in NPK + OM. Soybean received NPK + OM obtained lest root-shoot ratio, compared with other treatments, indicating that organic fertilizer application combined with NPK could promote the root growth of soybean. The soybean yield components was shown in decreasing order of NPK + OM > NPK > N + OM > N > CK, the similar trend was found in the yield of soybean, which indicated that long-term combinating application of organic manure and N, P, K fertilizer could increase the yield of soybean. P and K fertilizer could not be replaced by organic manure in study area deriving from the comparative yield of soybean between N + OM and NPK.关键词
