Abstract:
Taking apple M9T337 dwarf rootstock as test material.Four treatments were set in the experiment,control (CK)，bacterial fertilizer 120 g + normal fertilizer (T1)，bacterial fertilizer 240 g + normal fertilizer (T2)，and bacterial fertilizer 360 g + normal fertilizer (T3).The effects of different application amounts of microbial fertilizer on nutrient growth，soil characteristics and plant nutrient uptake of apple were studied，so as to provide a theoretical basis for improving apple quality and sustainable development.The results showed that different application amounts of microbial fertilizer significantly improved the vegetative growth and root activity of apple，and the total biomass，total root length，root tip number，root surface area and root activity increased by 35.2%，11.9%，59.4%，10.7% and 65.1%，respectively，compared with CK.T3 treatment had the best effect.Different application amounts of microbial fertilizer could significantly improve the physical and chemical properties of soil，and increase the contents of alkaly-hydrolyzed nitrogen，available phosphorus，available potassium and organic matter in soil，which increased by 63.1%，47.2%，35.5% and 72.3%，respectively，compared with the control group.The activity of urease，phosphatase and sucrase increased by 79.5%，50.8% and 75.4%，respectively，compared with CK.The content of total nitrogen，total phosphorus and total potassium increased by 66.5%，78.2% and 76.8%，respectively，compared with CK.The results showed that microbial fertilizer could improve the growth of apple M9T337 seedlings and play an active role in the growth process of apple.
