【摘要】 本试验采用国际晚近研究的新进展方法进行检测，试验表明土壤微生物总活性夏季比冬季强烈，人工森林生态系统比对照地（稀树草坡微生物总活性增强20倍，每年被分解转化的有机物质量（t／km~2）果园地比对照地增加1倍多，土壤微生物库中生物营养元素的库贮量（kg／hm~2）果园地比对照他也增加了1倍，土壤微生物对能源营养物质的转化归还量，果园和人工森林生态系统都比对照地增大。更多还原

【Abstract】 To adopt the present international research methods, the experimental results show that the total activity of soil microbe in summer is stronger than that in autumn, and its in the artificial forest ecosystem increases of 20 folds than that in the contrast field (the spare vegetation); the annual transformed-decomposed organical matters of the orchard increase of a fold than that of the contrast field lthe stored amounts of the nutrient element of the soil microbe storehouse in the orchard enhance of a fold than that of the contrast field, the transformed-returned amounts of the energy matter in orchard and artificial forest ecosystem is larger than that in the contrast fields.更多还原
