Studies On The Influence Of Fertilizer And Loading On The Yield And Quality Of Grape

In order to find out the requiring fertilizer characteristics and relationship between loading and production,quality of grape, to achieve the purpose of stable yield and high quality. This experiment, applying Summer Black Seedless,Red Globe,Wink as test material, using the formulated fertilizer technology, leaf nutritional analysis, soil nutrient diagnosis and other methods, determinating the body nutrient status of the three varieties in different physiological period, judging the nutrition situation of tree body; Studying the influence of different basic fertilizer on the the yield and quality of Summer Black Seedless, preliminary determine its fertilization scheme; Studying the influence of different loadings on the yield and quality of three varieties. Test indicated as follows:1,In Summer Black Seedless, the largest N,P,K fertilizer is:N=24.48kg/667m2, p=30.92kg/667m2, K=24.92kg/667m2, respectively, the appropriate fertilization of N, P and K is:24kg-25kg/667m2,29kg-31kg/667m2,23kg-25kg/667m2; In Red Globe, the largest N, P, K fertilizer is:N=23.94kg/667m2, p=20.87kg/667m2, K=20.98kg/667m2, respectively, the appropriate fertilization of N, P and K is:23kg-24kg/667m2,20kg-21kg/667m2,20kg-21kg/667m2; In Wink, the largest N, P, K fertilizer is:N=18.18kg/667m2, p=14.6kg/667m2, K=23.06kg/667m2, respectively, the appropriate fertilization of N, P and K is:18kg-19kg/667m2,14kg-15kg/667m2,22kg-23kg/667m2.2,In the formulated fertilizer experiment, when Summer Black Seedless is fertilizered with N=20kg/667m2,P=27kg/667m2,K=25kg/667m2; Red Globe is fertilizered with N=20kg/667m2,P=18kg/667m2,K=25kg/667m2; Wink is fertilizered with N=20kg/667m2,P=9kg/667m2,K=25kg/667m2; comprehensive benefit is the best.3,The cost is higher to apply cake fertilizer, but just has higher yield, the economic benefit can make up for the cost in investment, moreover, it is convenient to operate and should be adopted; The lowest cost and high yield is brought by applying pig manure, but it is more troublesome; Controlling Fertilizer rate within standard, the yield and quality of the treatment are good, and the absorption of nutriention is better than other two processing.4,In the southern shelter cultivation, it is suitable to control18-20clusters per plant of Black Seedless, namely the production is1750-2000kg/667m2, soluble solids content reach to17, comprehensive benefit is the best; Red Globe's appropriate loading is between10-12clusters, at this time its production is about1300-1400kg/667m2, soluble solids content is more than15; Wink should be controlled loadings between10-12clusters, namely the production is1200-1500kg/667m2,as which in good quality, and the best economic benefit.
