【摘要】 试验以11年生红富士苹果为材料,设置有机-无机复合土壤调理剂、生石灰和空白对照3个处理,研究有机-无机复合土壤调理剂对苹果园土壤理化性质、苹果产量和品质的影响。结果表明,施用土壤调理剂后苹果园土壤pH值和速效磷、速效钾含量显著提高,土壤细菌、放线菌和微生物总量增加,土壤酶活性显著提高,苹果果实品质得到明显改善。与对照相比,连续施用土壤调理剂两年后土壤pH值、产量和经济效益分别提高0.96个单位和10.85%、10.95%。因此本试验条件下果园施用有机-无机复合土壤调理剂可改善土壤理化性质、提高苹果产量和经济效益,且效果优于施用生石灰。更多还原

【Abstract】 In this paper,the effects of organic-inorganic compound soil conditioner on soil physical and chemical properties,and apple yield and quality were studied through field experiment with 11-year old Red Fuji apple trees as materials.Three treatments were designed as organic-inorganic compound soil conditioner,quicklime and blank treatment(CK).Soil conditioner improved pH value,available phosphorus and potassium contents,total amounts of bacteria,actinomycetes and microorganisms,soil enzyme activities and apple quality.Compared with CK treatment,the soil pH value,apple yield and economic benefit increased by 0.96 units,10.85% and 10.95% respectively after two-year continuous application of soil conditioner.In conclusion,the organic-inorganic compound soil conditioner could improve soil physical and chemical properties and increase apple yield and economic benefits,so it was superior to the application of lime.更多还原
