Abstract: Aiming at the problems in large amount of fertilization and unbalanced fertilization in balsam pear production, the effects of reducing application of liquid fertilizer on the yield and quality of balsam pear were studied in order to provide the basis for reducing fertilization of balsam pear. The results showed that reduced application of liquid fertilizer could increase the single fruit weight, yield and economic benefit of balsam pear. Among them, the liquid fertilizer application, which reduced 15% fertilization amount, had the best effect on increasing yield and economic benefit of balsam pear with increasing yield by 13.23% and economic benefit by 15.49% compared with conventional fertilization.
