多功能微生物制剂对农田栽参土壤养分状况的影响

以多功能微生物制剂的不同施用方法、不同施入水平对农田栽参土壤养分状况的影响作用进行了试验研究。结果表明：多功能微生物制剂对土壤养分状况改良效果明显，同时可以分解转化农田栽参土壤的有机质、全量NPK的含量，多功能微生物制剂作基肥施入和激活后作基肥施入土壤中有机质、全N、全P的含量均随施入量增加而降低，其中微生物制剂激活后以150 g/m2作基肥施入后有机质、全N和全P含量最低，分别为17.68 g/kg，1.63 g/kg、0.39 g/kg，对全K影响不显著；微生物制剂对人参土壤速效NPK含量都有提高，其中微生物制剂直接作基肥以150 g/m2施入时，对土壤中速效NPK含量作用显著，含量分别为18.77 mg/kg、98.02 mg/kg和1420.29 mg/kg，而且与对照及其它处理的不同水平达显著或极显著差异。多功能微生物制剂能够改善农田栽参土壤养分状况，合理的施用量和施用方式可以有效地提高土壤养分供应能力。

Effect on Ginseng Soil Nutrient Status by Cultivated Farmland with Multi-microbial Organic Treatment

The effect of soil nutrients of cultivated ginseng were studied by different methods of application and different content of multi-microbial organic treatment.Results showed that:multi-microbial organic treatment seriously improved soil nutrients,besides,decomposed organic matter and transformed total content of NPK in the cultivated ginseng soil.When the treatment was 150 g/m 2 as basic fertilizer addition after activated multi-microbial manure,the contents of soil organic matter,total N and P respectively...
