| 摘 要： | 在鄂西北地区，通过对龙须草的生长规律及其吸收氮、磷、钾养分的特性研究表明：在缺肥的土壤上种植龙须草，其氮、磷、钾肥的施用时期有3次，第1次是春季萌发生长期，第2次是生殖生长基本终止开始转入营养生长旺盛期，第3次是营养生长旺盛期的最后1个生长高峰期初期。氮肥和钾肥的施用，第1次用量应少，第2次用量应多，第3次可根据植株后期的生长情况而定；而磷肥则应早施，可作基肥第1次施肥时1次性大量施用。

| Abstract: | This research is about the growth rules and nutrient (nitrogen, phosphorus and potassium) absorbing characteristics of Eulaliopsis binata in the northwestern area of Hubei province. The result shows that in infertile soil, fertilizer applying should be done three times; first, in spring sprout period; second, at the turning point from reproduction growth period to vegetation growth period; third, at the beginning of final growth peak of vegetation growth period. The amaunt of ni-trogen and potassium fertilizer applied should be smaller in the first time, larger in the second time, and it should be determined according to the growth status of plants during later period. Phosphate fertilizer should be applied in large quantities as base fertilizer in the first time |
