生物有机肥替代化肥对葡萄生长与土壤肥力的影响
Effects of Bio-organic Fertilizer Replacing Part of Chemical Fertilizer on Grape Growth and Soil Fertility
摘要
Abstract
In order to clarify the effects of partial replacement of chemical fertilizer with organic fertilizer on the yield,quality and soil fertility of'Cabernet Sauvignon'grape,4 treatments were set in 2019-2020,including traditional water-fertilization(CK),optimized water and fertilizer management(Opt),and nitrogen fertilizer in the optimized water and fertilizer management replaced by bio-organic fertilizer with 20%(B1)and 40%(B2),respecteively.The nutrition content in soil and yield,quality of grape under different treatments were compared.The results showed that optimized water and fertilizer management and using bio-organic fertilizer to replace part of chemical fertilizer could improve soil physicochemical property,enhance soil fertility and promote the growth of grape.B1 treatment could significantly increase the economic profits of vineyards,and the average income in 2019 and 2020 increased by 33.59%compared with CK.B2 treatment could improve soil fertility better.Compared with CK,the pH and nitrate nitrogen content of B2 in 0-40 cm soil layer at maturity stage decreased,while organic matter increased significantly.Compared with Opt treatment,the contents of available phosphorus and available potassium of B2 in 0-40 cm soil layer at maturity stage significantly increased by 109.90%and 32.20%,respectively.Therefore,using bio-organic fertilizer to replace part of chemical fertilizer was an effective approach to achieve efficient,safe and sustainable production of orchards.关键词
