Comparative Analysis of Soil Nutrient,Microbial Diversity and Nutrient Quality of Two Main Varieties of Jujube in Yecheng,Xinjiang
The differences of soil nutrients,microbial diversity and nutritional quality of jujube were compared be-tween Junzao and Huizao,two main types of jujube planted in Yecheng,Xinjiang.The correlation between soil nutri-ents,microorganisms and nutritional quality of jujube was analyzed,and the influencing factors of nutritional quality of jujube were studied from the perspective of soil nutrients and microorganisms.Soil nutrients and nutrient quality inde-xes of jujube were determined by chemical analysis,and soil microbial diversity was analyzed by high-throughput se-quencing.The correlation between nutrient quality indexes of jujube and soil nutrients and microbial functional groups was studied by redundancy analysis of soil nutrients and microbial dominant phyla and genera.The results showed that the contents of total nitrogen(TN),available nitrogen(AN)and organic matter in soil of two main jujube in Yech-eng,Xinjiang were significantly different.The main reason for the change of bacterial community was soil TN value,and the main reason for the change of fungal community was soil AN value.The soil microbial diversity of Junzao ju-jube was higher than that of Huizao jujube.The soil microbial abundance and diversity of Junzao jujube were higher on the bacterial level,and the relative abundance and proportion of functional soil microorganisms such as Gracilibacillus,Bacillales and other phosphorous soluble microbes,nitrogen fixing microbes were higher,and the difference was sig-nificant.The nutritional quality of jujube,especially the contents of insoluble dietary fiber,Fe,K and Zn were signif-icantly different.And insoluble dietary fiber,K and sucrose contents were negatively correlated with TP(total phos-phorus)and OM(organic matter).The contents of Fe and Zn were positively correlated with Gracilibacillus and Ba-cillales.The contents of Mg,soluble sugar and soluble dietary fiber were negatively correlated with Paenibacillaceae.The correlation results showed that the nutritional quality of jujube was closely related to soil nutrients and microbial functional groups,and the combined effects of soil nutrients and microorganisms also affected the nutritional quality of jujube fruit.
