Effects of bio-organic fertilizer on yield,quality,and soil fertility of Yizhang navel orange
摘要
Abstract
To investigate the effects of bio-organic fertilizer on the yield and quality of Yizhang navel oranges,as well as soil fertility,8-year-old Newhall navel orange trees were selected as the test material in the Zhanxiang Navel Orange Orchard,Yizhang County,Chenzhou City.Three treatments were set up:conventional fertilization(CF),navel orange specific organic fertilizer(NOF),and bio-organic fertilizer(BOF).The total annual input of macronutrients per plant was the same across all treatments.The sprout fertilizer,fruit-stabilizing fertilizer,and fruit-enlarging fertilizer were the same for all treatments and were all used as chemical fertilizers.Only the winter fertilizer was different.Field experiments were conducted for two consecu-tive years,and soil fertility,soil microorganisms,autumn shoot leaf nutrition,fruit yield,internal and external fruit quality,and economic benefits were compared.The results showed that all organic fertilizer treatments improved soil fertility,the nutritional level of navel orange trees,fruit yield,flavor quality,and economic benefits,with BOF exhibiting superior effects.Compared with CF,BOF application increased soil organic matter,alkali-hydrolyzable nitrogen,and available potassium contents by an average of 40.77％,17.66％,and 29.48％,respectively.Fruit yield,single fruit weight,fruit transverse diameter,and peel brightness increased by 32.29％,37.16％,14.38％,and 22.03％,respectively.Fruit soluble solids,soluble sugars,and vitamin C contents increased by 19.52％,17.92％,and 14.34％,respectively,while titratable acid content decreased by 36.96％.BOF is recommended as the winter fertilizer for Yizhang navel oranges.关键词
