STUDY ON FERTILIZER APPLYING PERIOD OF EULALIOPSIS BINATA AND ITS GROWTH RULE AND NUTRIENTS ABSORBING CHARACTERISTICS
龙须草的生长规律及养分吸收特性与施肥时期的研究

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
