通过氮肥和氮磷肥对草木樨生产性能影响的研究 ,证明磷肥能增加草木樨地上和地下生物量积累及种子产量 ,同时磷肥还提高了草木樨的粗蛋白含量和积累量 ,提高了根瘤鲜重 ,盛花期以前 ,磷肥增加了草木樨的 NDF和 ADF含量 ,盛花后减缓了纤维化过程。氮磷肥配施提高了草木樨产量和粗蛋白含量 ,对 NDF和 ADF含量的影响类似于单施磷肥 ,方差分析表明施氮磷肥间在初花期存在显著互作关系 ,施磷肥对初花期和绿荚期产量的贡献率大于施氮肥。对初花期和绿荚期草木樨产量的回归分析得到了单施磷肥和氮磷肥配施的二次肥料效应方程 ,并作出了氮磷肥配施在这 2个物候期的肥料效应曲面
Through the research on the influence of nitrogen and nitrogen and phosphorus on the production performance of the plant, it was proved that the phosphorus fertilizer could increase the biomass accumulation and the seed yield of aboveground and underground plants, and the phosphorus fertilizer increased the crude protein content and accumulation of the plant and increased the fresh weight of the root nodule , Before the full flowering period, phosphorus fertilizer increased the NDF and ADF content of the plant, after full bloom slowed down the process of fibrosis. Nitrogen and phosphate fertilizers increased the yield and crude protein content, and had similar effects on the NDF and ADF contents. Phyto-analysis showed that there was a significant interaction between nitrogen and phosphorus fertilizers at early flowering stage, The contribution rate of pod production is greater than that of nitrogen fertilizer. The regression analysis of the yield of P. indica at the beginning of florescence and the green pod stage obtained the secondary fertilizer effect equation of single application of phosphorus fertilizer and nitrogen and phosphorus fertilizers and made the fertilizer effect surface of the application of nitrogen and phosphorus fertilizer in these two phenophases
