According to study of Li Sha^ , the effect of fertilization is not only related to the fertilization period, methods, and amount of nitrogen, phosphorus and potassium fertilizers, but also closely related to the ratio of nitrogen, phosphorus and potassium· Fertilizer is an essential factor affecting the yield of strawberry, and its components are mutually promoted and restrained- Only through grasping the relationship between each factor and the yield, can we adjust the components of fertilizers in an effective and balanced manner, so as to obtain a scientific and reasonable fertilization method^4 ^ · Integration of water and fertilizer application is a technology for simultaneous control of water and fertilizer. [...]of absorbing water, crops also absorb nutrients· Crops can supply the nutrients and water necessary for crops, which can make the water and fertilizer infiltrate deeper and wider according to needs of crops· However, in the fertilization for strawberry , many studies only recommended the application of potassium fertilizer, and did not involve the ratio of nitrogen, phosphorus and potassium. [...]through implementing the integrated cultivation of water and fertilizer for strawberry, we carried out. this experiment for six market available water-soluble fertilizers, in order to make clear the trend of demands for nitrogen, phosphorus and potassium nutrients in the strawberry topdressing process, guide local farmers to strictly control the fertilizer amount, make the fertilizer application structure and the fertilization period reasonable, realize simultaneous control of water and fertilizer, accordingly to provide theoretical basis for pollution-free and high quality and high efficient cultivation of strawberry. 2 Materials and methods 2. For the storage resistance , the fruit treated with calcium protein, volfertile and Batian showed strong storage resistance, that treated with Wangdefeng was moderate , and that treated with Jiashili and Stanley was weak. 3.2 Effects of different water soluble fertilizers on growth characteristics and disease resistance of strawberry In the integrated, water and fertilizer, mode, different water-soluble fertilizers have different .effects on the growth characteristics and disease resistance pf strawberry (Table 3:|s Strawberry plants treated with Batian, Wangdefeng, Stanley, and calcium protein .showed strong growth, and that treated with Jiashili and volfertile showed stronger growth, the Strawberry plants all. showed a Semi-opening pattern; for the plant height, the Strawberry plants treated with Batian showed the best; growth, the plant height was 53 cm, followed by Stanley; plants treated with Jiashili had the height of 46 cm. mildew occurred, other treatments also had occurrence of powdery Through investigation, after treatment with Stanley, serious powdery mildew and Botrytis cinerea, but the diseases were not serious. 3.3 Effects of different water soluble fertilizers on strawberry yeild. In summary, in the integrated water and fertilizer mode, the application of volfertile water soluble fertilizer (N-P-K = 16-6-36) has significant effects on strawberry yield and quality. Besides , the integration of water and fertilizer has certain effects on the economic traits, growth characteristics, disease resistance and yield of strawberry.
