Effects of Biofertilizer Treatment on the Water Content and Fruit Quality of Kiwifruit
摘要
Abstract
Taking seven-year-old'Donghong'kiwifruit as the experimental material and employing an L16(43)orthogonal design,a trial was conducted to investigate the effects of combined application of Bacillus licheniformis(D bacterial fertilizer),Bacillus amyloliquefaciens(J bacterial fertilizer),and Bacillus mucilaginosus(Y bacterial fertilizer)on soil moisture,root,leaf,branch,and fruit moisture content as well as fruit quality in a kiwifruit orchard.The experiment measured the moisture content of the soil and various organs at fruit maturity,fruit growth,and physiological indicators.Correlation analysis and principal component analysis of fruit quality were carried out to determine the optimal fertilization combination,in order to provide reference for kiwifruit cultivation.The results showed that at fruit maturity,the moisture content of the soil,roots,leaves,branches,and fruits were 20.10％—29.25％,76.61％-86.33％,71.35％-87.35％,69.37％-84.42％,and 80.03％-94.58％,respectively,showed significant differences from the control(CK)(P＜0.05).The dominant factor affecting root moisture content was the J bacterial fertilizer,while for the others,it was the Y bacterial fertilizer.The fruit shape index,reduced sugar,soluble sugar,titratable acid,soluble protein,vitamin C,and soluble solid content were 1.11-1.34,1.55％-4.04％,46.41-72.04 mg·g-1,1.26％-0.66％,4.99-7.28 mg·g-1,126.67-206.65 mg·(100 g)-1,and 12.96％-17.20％,respectively.Correlation analysis showed that the titratable acid content was highly negatively correlated with the contents of D,J,Y bacterial fertilizers,reducing sugar,and soluble sugar.Fertilization could promote fruit growth,reduce acidity,increase sweetness,maintain orchard soil moisture,and fruit moisture content.The combination of D bacterial fertilizer 40 g,J bacterial fertilizer 20 g,and Y bacterial fertilizer 60 g per plant significantly affected soil moisture content.The combination of D bacterial fertilizer 40 g,J bacterial fertilizer 20 g,and Y bacterial fertilizer 40 g per plant could increase the moisture content in roots,leaves,and fruits with minimal impact.The combination of D bacterial fertilizer 20 g,J bacterial fertilizer 40 g,and Y bacterial fertilizer 60 g per plant could enhance fruit diameter,while the combination of D bacterial fertilizer 40 g,J bacterial fertilizer 20 g,and Y bacterial fertilizer 60 g per plant could improve the intrinsic quality of the fruit.关键词
