摘要
[目的]探讨不同土壤调理剂对盐碱地的改良效果及水稻产量的影响。[方法]在宁夏盐碱地施用8种土壤调理剂,研究不同调理剂对盐碱地土壤的理化性质、pH、盐分离子以及水稻生长发育和产量的影响。[结果]施用土壤调理剂后,不仅降低了土壤容重、pH并对土壤盐分离子产生不同影响,而且加快了水稻生育进程,增加了水稻的总茎数和穗数,提高了水稻产量。[结论]施用不同土壤调理剂均对土壤及水稻生长有一定的积极效果,ORYKTA、丹路菌剂、丹路菌肥的增产效果较为显著。
[Objective] The research aimed to discuss the effects of different soil conditioner on the improvement effect of saline land and rice yield.[Method] 8 kinds of soil conditioners were applied in saline land of Ningxia to study the effects of different soil conditioner on the chemical and physical properties,pH value and salt ions of soil in saline land and the growth and yield of rice were studied.[Result] The application of soil conditioners not only decreased the bulk density and pH value of soil,had different effects on soil salt ions,but it also sped up the growth process of rice,increase the total rice stems,panicle number and yield.[Conclusion] Applying different soil conditioners all had certain positive effects on soil and rice growth and ORYKTA,Danlu microbial inoculum and Danlu bacterial fertilizer had more significant effects on increasing yield.
