Effects of a long-term utilization of different base-fertilizers on soil environment in solar greenhouse
长期施用不同基肥对日光温室土壤环境的影响研究

An elementary study was conducted to study the influence of a long-term utilization of different base-fertilizers on physical and chemical properties,and the bio-environment of soil in solar greenhouse.The results show that the soil treated by straw organic fertilizer owns good physical and chemical properties,and higher fertility.The enzyme activity of the treated soil is high with vigorous microorganism vitality and the ratio of bacteria to fungi is stable.The general soil fertility of soil treated by straw organic fertilizers is the highest among the three treatments.The long time application of the processed chook manure fertilizer induces the soil's acidity stronger,the soil nutrient content is the mediam of three treatments,the enzyme activity higher,the population of soil bacteria greater,but the fungi quantity excessive,which may cause the multiplication of germina.As the base-fertilizer,the slow-released fatty has positive influences on soil available nutrients.But the organic matter content,soil enzyme activity and microorganism activity of the treated soil are all lower.The cooperative application of organic-inorganic fertilizers according to the actual circumstance should be taken to attain the ideal results in the production.
