Jinsixiaozao ZHANG Zhi-ying, ZHANG Wang-lin, ZHANG Lian-shui HUBEI AGRICULTURAL SCIENCES    2024, 63 (4): 17-23.   DOI: 10.14088/j.cnki.issn0439-8114.2024.04.004 Abstract （37）      PDF （3590KB）（6）       Knowledge map    Save Four treatments were set up, including single application of chemical fertilizer （T1）, single application of organic fertilizer （sheep manure） （T2）, combined application of 50% organic fertilizer nitrogen and 50% chemical fertilizer nitrogen （T3）, and no fertilization control （CK）. The effects of different fertilization methods on the physical and chemical properties of 0~20 cm soil in the jujube orchard and the yield and quality of Zizyphus jujuba cv. Jinsixiaozao were studied. The results showed that different fertilization treatments had different effects on the physical and chemical properties of 0~20 cm soil in the jujube orchard. Compared with CK and T1, the soil bulk density and pH of T3 decreased significantly （P<0.05）, and the soil porosity, organic matter content, total nitrogen, total phosphorus, available nitrogen and available phosphorus content of T3 increased significantly （P<0.05）. Compared with CK and T1, the appearance quality of jujube fruit in T2 and T3 was significantly improved, the longitudinal diameter and transverse diameter of jujube fruit treated with T2 and T3 were significantly increased （P<0.05）, the content of total soluble sugar and VC in jujube fruit treated with T2 and T3 were also significantly increased, and the bad fruit rate of T2 and T3 was decreased. The single fruit weight and yield of each fertilization treatment were significantly higher than those of CK. The yield and net income of jujube fruit in T3 were the highest, and were significantly higher than those of T1 （P<0.05）. In conclusion, the combined application of 50% organic fertilizer nitrogen and 50% chemical fertilizer nitrogen could effectively improve the physical and chemical properties of soil and significantly enhance the yield and quality of jujube fruit.

Four kinds of biological bacterial fertilizers including water-soluble saline-alkali soil composite bacteria （A）, insoluble saline-alkali soil composite bacteria （B）, Bacillus subtilis （C）, Bacillus amyloliquefaciens （D） and three application gradients were set up. The growth index of wheat seedings, physical and chemical properties and microorganisms quantity of soil were determined. The result showed that the plant height, chlorophyll SPAD and aboveground dry matter of wheat seedings treated with four kinds of biological bacterial fertilizers A, B, C and D were higher than those of CK, and these growth indexes of wheat seedlings in each treatment increased with the increase of the amount of biological bacterial fertilizers. The contents of soil organic matter, total nutrients （total nitrogen, total phosphorus and total potassium） and available nutrients （alkali-hydrolyzable nitrogen, available phosphorus and available potassium） of wheat treated with four kinds of biological bacterial fertilizers were higher than those of CK. The number of culturable bacteria and actinomycetes in the soil of potted wheat treated with each biological bacterial fertilizer was higher than that of CK, while the number of fungi was lower than that of CK. Through principal component analysis, Bacillus subtilis （C） had the best effect on improving soil when the application amount was 0.80 g/kg.
