摘　　要：为研究不同微生物菌肥的施用量对苹果营养生长、土壤理化性质和植物营养元素含量等方面的影响,以M9T337型苹果矮化砧木为材料,设4个试验处理:对照组(CK)、120 g菌肥+常规施肥(T1)、240 g菌肥+常规施肥(T2),360 g茵肥+常规施肥(T3)。研究结果表明:在不同微生物菌肥的施用下,苹果的营养生长明显增强,其总生物量、总根长、总根尖数、根表面积、根系活力等与CK相比,分别增加了36.07%、59.4%、10.7%、66.27%,其中以T3效果最佳。施用不同的微生物菌肥可以明显地改善土壤的物理和化学性质,使土壤碱解氮、速效磷、速效钙、有机质的含量较CK分别提高64.26%、48.33%、36.64%、73.45%。同时,与CK相比,尿素酶、磷酸酶、蔗糖酶活力分别增加了78.62%、51.94%、76.39%。与CK相比,植株株全氮、全磷、全钙含量分别增加65.67%、77.31%、77.92%。表明微生物菌肥可以促进苹果M9T337幼苗的生长,并对苹果的生长有正面影响。研究结果可为改善苹果质量和实现苹果的可持续发展奠定基础。In this study,M9T337 apple dwarf rootstock was used as material,and four treatments were set up:control group(CK),120 g bacterial fertilizer+conventional fertilizer(T1),240 g bacterial fertilizer+conventional fertilizer(T2),360 g grass fertilizer+conventional fertilizer(T3).This project aimed to lay a foundation for improving the quality of apples and realizing the sustainable development of apples by studying the application amount of different microbial fertilizer on apple nutritional growth,soil physical and chemical properties and plant nutrient elements content.The results showed that the vegetative growth of apples was significantly enhanced under the application of different microbial fertilizers.Compared with CK,the total biomass,total root length,total number of root tips,root surface area and root activity increased by 36.07%,59.4%,0.7%and 66.27%,respectively,and T3 had the best effect.Applying different microbial fertilizer can obviously improve the physical and chemical properties of soil,and the contents of alkali-hydrolyzed nitrogen,available phosphorus,available calcium and organic matter in soil are increased by 64.26%,48.33%,36.64%and 73.45%,respectively,compared with CK.At the same time,compared with CK,urease,phosphatase,sucrose activity increased by 78.62%,51.94%,76.39%,respectively.Compared with CK,the contents of total nitrogen,total phosphorus and total calcium increased by 65.67%,77.31%and 77.92%,respectively.The results showed that the microbial fertilizer could promote the growth of apple M9T337 seedlings and had a positive effect on the growth of apple.
