采用“3414”试验方案,考察氮、磷、钾肥料配方施肥对太白贝母“树儿子”期产量的影响。结果表明,太白贝母对氮、磷、钾的总体需求较低,适度施用氮肥可使鳞茎质量増长,生产宜采用低量施肥的方式。
The experiment of “3414” was used to study the effects of nitrogen, phosphorus and potassium fertilizers on the yield of Fritillaria patens. The results showed that the overall demand for nitrogen, phosphorus and potassium of Fritillaria cirrhosa was low. Appropriate application of nitrogen fertilizer could increase the quality of the bulb, and low-level fertilization should be adopted in production.
