Abstract:

To study the effects of chemical fertilizer combined with organic fertilizer on soil physical and chemical properties, soil enzymes activities, and fruit quality and yield of cherry, a field experiment was conducted in Tongzhou District, Beijing, China. A total of 6 treatments were set including control (CK, no fertilizer) and 5 treatments with different proprotion of organic fertilizer. Except CK, the N input in the other treatments were equal. The differences of soil physical and chemical properties, soil enzymes activities, fruit quality indexes and fruit yiled were monitored among treatments. Compared with CK and the treatment with pure chemical ferilizers, the treatment with 50% (based on N input) chemical fertilizer+50% organic fertilizer could significantly (P<0.05) improve the contens of soil organic matter, total nitrogen, available nitrogen, available phosphorus, available potassium, and activities of soil urease, protease, alkaline phosphatase, dehydrogenase. Besides, this treatment could significantly increase viatamin C content and sugar-acid ratio in fruit without significant yield reduction. Thus, for cherry production in the test area, 50% chemical fertilizer+50% organic fertilizer was the recommended fertilization method.

Key words: combined application of chemical fertilizer and organic fertilizer, fertilizer reduction, soil nutrients, soil enzyme activity, fruit quality
