【Objective】 To improve the quality of jujube, ensure the yield of jujube, reduce the input of chemical fertilizer and reduce the environmental risk by studing the application of organic fertilizer and biological fertilizer in combination with chemical fertilizer 【Method】 The field location experiments reduction by alternative organic fertilizer efficiency tests were set to partly replace biological organic fertilizer processing (Bio-organic fertilizer, BOF), fertilization of chemical fertilizer treatment, (CF) and blank treatment (CK), the effects of biological organic fertilizer replacing chemical fertilizer on jujube yield structure were studied and red jujube orchard economic benefit was analyzed. 【 Result 】 The data showed that using organic fertilizer partly replacing fertilizer could increase the red jujube yield by 409.5 kg/hm2 (P<0.05), compared with single application of chemical fertilizer treatment (6 427.5 kg/hm2) and blank treatment (4 273.5 kg/hm2), the increase was 6.4% and 59.9%, respectively. The single fruit weight of jujube increased significantly. In the mature stage, the single fruit weight of jujube was respectively BOF (19.8 g) >CF (18.1 g) >CK (15.1 g). The bearing branch lengths of BOF treatment jujube were 17.2 cm and 27.9 cm at flowering stage and fruit expansion stage, respectively, which were significantly higher than those of the CF treatment and the CK treatment (P<0.05).The cracking rate of jujube decreased from CK (18.8%) and CF (15.7%) to BOF (13.1%). The comprehensive economic benefit analysis showed that compared with CF, BOF treatments could increase revenue by 4 389.0 RMB /hm2, and reduce fertilizer consumption by 18.2%. 【Conclusion 】 In order to achieve the purpose of high quality and high yield of jujube and fertilizer reduction efficiency, it is necessary to use the way of bio-organic fertilizers replacing chemical fertilizer. The results of this study has provided a reference for the rational use of biological organic fertilizer and the combination of chemical fertilizer used approach, enrich the research and application of orchard nutrient resources use in jujube garden. This is the technical support for the healthy development of jujube industry.
