| 摘 要： | 通过田间试验,探讨氮、磷、钾配施对威宁球茎草芦生物学性状、鲜草产量及植株营养成份的影响,并筛选出适宜的氮、磷、钾肥用量。结果表明:施肥处理比不施肥处理,其株高、分蘖数和鲜草产量最大增幅分别为13.21%、18.32%和56.87%。鲜草产量平均增产1 345.31 kg/667 m2,提高了34.24%;粗蛋白质含量随氮、钾肥施用水平的增加而提高,其中,NPK+1/2N处理的粗蛋白质含量最高达14.83%,提高了38.2%;经济效益每667 m2收入增加186.65～790.25元,提高88.62%～375.15%。 |

| Abstract: | Through field experiment, study on the nitrogen and phosphorus and potassium fertilizers on biological characters of Phalaris tuberosa L Cv. Weining , fresh grass yield and plant nutrients influence , Selected suitable nitrogen and phosphorus and potassium fertilizer. The results showed that fertilization ratio and fertilization and tiller number and fresh grass yield is respectively 13.21% and 18.32% and 56.87%, Compared with no fertilizer treatment. The fresh grass yield of Phalaris tuberosa L Cv. Weining arrived at the average yield of 1345.31 kg/667m2 about nine fertilizer treatments, It was increased by 34.24%. The crude protein content arrived at 14.83% with nitrogen and potassium application levels, h increased by 38.2%. At the same time the fertilization economic benefits are higher than those of fertilizer treatment, Their economic benefit achieved at 186.65 - 790.25yuan/ 667m2, They were increased by 88.62% - 375.15%. |
