| 摘 要： | 目的]为了解小黑麦对N、P、K、有机肥的原始反应。方法]采用地表2 m以下的非耕作生土,研究不同肥料对生产上正在推广的饲料小黑麦中饲237各生育期植株生长状况、生理功能及成熟期生物产量、经济产量的影响。结果]结果表明,NP、NPK、M、NPK＋M处理的小黑麦各生育期株高、叶面积、干物质量、倒二叶叶绿素含量及籽粒产量均明显高于单施N、P、K处理及CK,而各生育期倒二叶SOD、POD活性明显低于单施N、P、K处理及CK,而且最终以N、P、K、有机肥配施小黑麦生物产量及籽粒产量最高。单施N、P、K肥处理对小黑麦生物产量和籽粒产量的作用表现次序为N〉P〉K。结论]小黑麦对NP配合施用反应敏感,同样对优质有机肥反应很敏感,同时表现出在逆境中生长的适应性。

| Abstract: | Objective]The research aimed to investigate the triggering response of triticale to N,P,K and M in raw soil.Method]Pot experiments were carried out to study the effects of different fertilizer treatments on the growth and physiological function at different growth stages,dry weight in plant and grains yield at maturity of Zhongsi 237 in raw soil.Result]The results indicated that the plant height,leaves area,dry weight in plant,chlorophy content in leaves at different growth stages and grains yield under NP,NPK,M,NPK+M treatments were higher than those under N,P,K treatments and CK.And the POD,SOD content in leaves at different growth stages under NP,NPK,M,NPK+M treatments were lower than those under N,P,K treatments and CK.Under NPK+M treatment the dry weight in plant and grians yield were the highest.The order of dry weight in plant and grains yield among N,P,K treatments was N>P>K.Conclusion]Triticale was sensitive to interaction between nitrogen and phosphorus,and also sensitive to organic fertilizers.And the triticale put up the adaptability under adverse circumstance. |
