摘  要：
采用裂区试验设计,田间试验和室内分析相结合测定不同种植密度和施磷钾肥对秣食豆种子产量及构成因素的影响。结果表明,种植密度以14.28万株/hm~2秣食豆种子产量最高,为2254.76kg/hm~2;施肥水平以P2O545kg/hm~2和K_2O 75kg/hm~2秣食豆种子产量最高,为2144.44kg/hm~2;在密度和施肥互作效应下,14.28万株/hm~2的密度下施P2O530kg/hm~2和K_2O 50kg/hm~2,秣食豆种子产量最高,为2369.05kg/hm~2,显著(P<0.05)高于其他组合,最大增产幅度为30.67%。单株荚数、单株粒数、分枝数、主茎荚数、百粒重与单株产量均呈显著(P<0.05)正相关,密度与施肥及其互作效应对秣食豆产量因子的作用效应表现为:对单株产量、单株荚数、单株粒数、分枝数、百粒重均影响显著;对种子品质的作用效应表现为:施肥影响显著,而密度及密度与施肥的互作影响不显著。

摘  要：
In order to study the influencing factors on seed yield and quality of fodder soybean[Glycine max(L.)Merr.],the experiment was carried out by the combination of field test and field analysis to discuss the effects of different planting density and fertilization on the seed yield and constituent factors.The results showed that the seed yield was the highest when the planting density was 14.28 million/hm~2,the yield was 2254.76 kg/hm~2,and when the fertilization level was P_2O_5 45 kg/hm~2,K_2O 75 kg/hm~2,the seed yield was the highest at 2144.44 kg/hm~2.The seed yield was the highest when the density was 14.28 million/hm~2,the fertilization level was P_2O_5 30 kg/hm~2,K_2O 50 kg/hm~2,which was significantly higher than that of other combinations at 2144.44 kg/hm~2(P<0.05)and the maximum increase of yield was 30.67%.There were significant positive correlations between the number of pods,the number of whole grains,the number of branches,the number of pods and the hundred grain weight of the whole plant,and the yield per plant were significantly correlated with the effects of different planting densities and fertilization levels on seed yield factors(P<0.05).The effects of density,fertilization and their interaction on the yield factors were as follows:the effects on the yield per plant,the number of pods per plant,the number of grains per plant,the number of branches and the hundred grain weight were all significant.The effects of different planting densities and fertilization levels on seed quality were as follows:fertilization had significant effect,the density,density and their interaction had no significant effect.
