Effect of Organic Fertilizer Replacing Chemical Fertilizer on Grape Yield Quality and Soil Nutrients
[Objective]To investigate the effect of organic fertilizers replacing chemical fertilizers on the quality of grapes and soil nutrients of orchards in Xiaoxian.[Method]Taking the facility grapes as the research object,set no fertilization(T1),conventional fertilization(T2),optimized chemical fertilization(T3),organic fertilizer replacing 15%chemical fertilizer(T4),organic fertilizer replacing 30%chemical fer-tilizer(T5),organic fertilizer replacing 15%N(T6),and organic fertilizer replacing 30%N(T7).[Result]Different treatments of organic fertilizers replacing chemical fertilizers increased soil pH,organic matter,total nitrogen and total potassium contents by 1.72%-3.03%,5.62%-13.30%,5.71%-21.90%and 7.37%-11.58%,respectively,compared with T2 treatment.For T4 and T5 treatment,grape soluble sol-ids,sugar-acid ratio content were elevated 5.06%and 1.74%,7.28%and 2.08%,respectively,soil cation exchange and available potassium content were increased 4.85%and 5.45%,25.76%and 7.12%,respectively,the fruit reducing sugar,vitamins,and soil total phosphorus content were reduced;T4 treatment also increased grape yield and soil available phosphorous by 13.26%and 44.42%,respectively.T6 treat-ment increased grape yield,soluble solids,sugar-acid ratio and vitamin content by 1.74%,3.13%,9.38%and 3.64%,respectively,and in-creased soil pH,organic matter,total potassium,total phosphorus and available phosphorous content.T7 treatment decreased grape yield,re-ducing sugar,soluble solids,sugar-acid ratio and vitamin content by 13.84%,1.27%,0.41%,2.20%and 3.73%,respectively.[Conclusion]Combining fruit quality and soil quality,T4 treatment has the best effect.
