叶面喷施功能肥料对察隅"金隅"猕猴桃果实品质的影响
Effects of Foliar Spraying of Functional Fertilizers on Fruit Quality of Chayu"Jinyu"Kiwifruit
摘要
Abstract
In order to improve the nutritional value of kiwifruit in Chayu County,Xizang,and explore reference for mineral nutrition of kiwifruit.This study used six-year-old"Jinyu"kiwifruit as the test material.Foliar spraying experiments were conducted with selenium,zinc,and calcium fertilizers during the young fruit stage,and the appearance indicators such as single fruit weight and the content of nutrients such as vitamin C were measured.Principal component analysis was used to comprehensively evaluate the fruit quality,and the effects of foliar spraying with selenium,zinc,and calcium fertilizers on kiwifruit fruit quality were investigated.The results showed that foliar application of selenium could improve the selenium content of fruit,and the kiwifruit treated with 15 mg/L selenium fertilizer at a rate of 30 L/mu had a selenium content of 0.05 mg/kg,meeting the standard of selenium-enriched fruits.Additionally,the quality of the fruit,including single fruit weight,longitudinal diameter,transverse diameter,and fruit hardness was improved.Foliar spraying of zinc fertilizer could increase the contents of vitamin C,soluble solids and zinc in fruits.Foliar spraying of different concentrations of calcium fertilizer significantly increased calcium content.When 0.3%calcium fertilizer was sprayed until water dripped from the leaves,the calcium content of the fruit reached its peak,at 1 261.66 mg/kg.Foliar calcium application also improved fruit quality and effectively slowed down the decrease in fruit firmness after 15 days of storage at room temperature,but had no significant effect on fruit shape.Selenium,zinc and calcium fertilizers could increase the content of corresponding mineral elements in fruits,and comprehensively improve the nutritional quality of fruits.关键词
