| 摘 要： | 应用四元二次通用旋转组合设计研究了银川平原二代节能日光温室春茬辣椒对生物有机肥、氮肥、磷肥和钾肥的反应及其合理施用量。结果表明,供试土壤有效养分供肥特点表现为低氮、高磷、高钾,且因施肥量大及排水不畅,土壤表现为轻度盐渍化特征;氮素是决定辣椒生长发育和产量的最主要影响因子;四种肥料对辣椒产量的作用顺序为氮肥有机肥磷肥钾肥;辣椒稳产51.13 t.hm-2以上的适宜施肥量为有机肥3 000~6 000 kg.hm-2,N 633~750 kg.hm-2,P2O575~225 kg.hm-2,K2O 90~225 kg.hm-2;供试土壤最佳投肥水平m(N)∶m(P2O5)∶m(K2O)为10∶1∶1.2。

| Abstract: | Effect and optimum application rate of bio-organic manure,N,P and K in hot pepper production in Yinchuan Plain were studied using quaternion uniform-precision rotatable central composite design.The result shown that the soil has less available N,but more available P and K,and mild salinization characteristics due to high fertilizer application and drainage problem.N is the determination factor for hot pepper growth and production.The order of four fertilizer effect on hot pepper growth is:N>organic manure>P... |
