摘 要:采用田间试验,设置了8个不同施肥处理,研究不同施肥处理下光叶紫花苕在四川紫色丘陵区的产量和效益。结果表明,不同施肥处理对光叶紫花苕产量、产量相关性状和养分积累影响差异显著。不施氮肥的处理(60 kg/hm2P2O5和60 kg/hm2K2O)鲜草总产量、第1次刈割和第2次刈割产量均显著高于其它处理,该处理株高、单株体积和单株鲜重增长迅速。适量的化肥配施绿肥专用肥(37.5 kg/hm2纯N,60 kg/hm2P2O5,60 kg/hm2K2O和绿肥专用肥30 kg/hm2)显著提高种子产量和总经济效益,单株一级分枝、单株体积和单株鲜重表现明显优于其它处理。In order to clarify yield and benefit of Vicia villosa in the purple hilly area of Sichuan under conditions of different fertilizers, the field experiments with treatments of eight different fertilizers were conducted, and the yield, yield related traits and benefit of Viola villosa were studied. The results showed that the yield, yield related traits and benefit of Vicia villosa under different fertilizer conditions were significant different. The fresh yield, the first cuttings and the second cutting yield of Vicia villosa with treatment of 60 kg/hm2 phosphorus pentoxide and 60 kg/hm2 burnt potash without nitrogen, were significantly higher than that with other treatments, at the same time, the plant height, volume per plant and fresh weight per plant grew rapidly. Under fertilizer amount ( 37.5 kg/hm2 nitrogen,60 kg/hm2 phosphorus pentoxide, 60 kg/hm2bumt potash and 30 kg/hm2green manure fertilizer), the seed yield, total economic benefits significantly increased, and the level of branching, volume per plant and fresh weight per plant were much better than that of others.
