对黄土高原残垣沟壑区隰县试区农林复合经营田和农田中细菌、真菌、放线菌,以及细菌类群进行种群和数量上的比较。通过分析表明,农林复合经营能显著提高土地地力。因此可以加强农林复合经营,结合精耕细作,施用农家肥,以更好地改良土壤,使农业的高效性更好的显现出来。 The population and quantitative comparison of bacteria, fungi, actinomycetes, and bacterial groups in farmland and farmland in agro-forestry complex in the Xinyi pilot area in the gully area of ​​the Loess Plateau were studied. Through the analysis shows that agroforestry can significantly improve land productivity. Therefore, it is possible to strengthen the agroforestry operation, combine with intensive farming, and apply manure to better improve the soil and make the efficiency of agriculture appear better.
