云南重楼高产栽培施肥研究
Effective Study of Fertilizer on Yield of Paris polyphylla var. yunnanensis (Fr.) Hand
【摘要】 为探明肥料施用对云南重楼产量的影响,采用不同梯度施肥水平研究有机肥对云南重楼产量的影响;采用三元二次回归正交设计方法研究NPK无机肥对云南重楼产量的影响。结果表明,云南重楼的高产需要较高的肥力条件,在中等以下的土壤肥力条件下,云南重楼的最佳农家肥施肥量为3000~4500kg/667m2之间。N素和P素是云南重楼生长的养分限制因子。可见,施用适宜有机肥和N、P无机肥可以大幅度提高云南重楼单位面积产量。
【Abstract】 The study is on the effect of fertilizer on growth ofParis polyphylla var.yunnanensis (Fr.)Hand. To adopt different grading levels amount of organic fertilizer to study the output of Paris; To use quadratic regression orthogonal design with three factors to study the effect of NPK non-organic fertilizer on the output of Paris; High fertilizer can produce high yield ofParis polyphylla var. yunnanensis ; for soil fertility below medium, the suitable amount of farmyard manure is 3000~4500kg /667m2; Element N and P is the critical factors for the growth ofParis . Appropriate organic fertilizer and non-organic fertilizer can improve greatly the output ofParis polyphylla var.yunnanensis .
【Key words】 Paris polyphylla var. yunnanensis (Fr.) Hand; organic fertilizer; non-organic fertilizer; yield;
