| 摘 要： | 为了筛选出适宜红壤性低产地的土壤改良剂,以芝麻作为试验作物,比较熟石灰、微生物菌剂、生物有机肥和4种自制改良剂的应用效果。结果表明:自制改良剂2号(SSA-2)应用效果较好,芝麻产量较对照增加24.5%,主要增加了单株蒴果数,较对照增加23.6%,是芝麻地土壤改良和实现芝麻增产增效的一种较好的改良剂。该改良剂对土壤理化性状也有一定的影响,主要是提高土壤有机质含量和有效锌含量,分别较对照增加5.7%和8.0%。因此,综合考虑芝麻生产效益和土壤结构改良效果,认为SSA-2是一种较好的土壤改良剂,明显优于石灰、生物有机肥、微生物菌剂和其他3种自制改良剂。

| Abstract: | In order to screen out suitable soil amendment for low-yielding red-soil land,using sesame as the tested crop,this study compared the application effects of white lime,microbial agents,bio-organic fertilizer,and 4 kinds of self-made soil amendments.The results showed that self-made soil amendment No.2(SSA-2) had the best improvement effect on the sesame field,the sesame yield in SSA-2 treatment was about 24.5% higher than that in the control,and the number of capsules per plant in SSA-2 treatment was about ... |
