Effects of Different Water-soluble Fertilizers on Yield and Quality of Strawberry under Integrated Application of Water and Fertilizer

Taking Hongyan strawberry as the material and PE drip irrigation tape and fertilizer applicator as the tool of integrated application of water and fertilizer, this experiment studied the effects of 6 fertilizers including Batian, Jiashili, Wangdefeng, Stanley, Wofute and calcium protein on yield and quality of strawberry. The experimental results showed that different water-soluble fertilizers had different effects on the main economic traits of strawberry. For the maximum single fruit mass, the highest was Wofute treatment (28.72 g), followed by calcium protein treatment, and the lowest was Stanley treatment (23.89 g). The fruit treated with Batian, Wofute and calcium protein was hard in the texture, the fruit treated with Wangdefeng was harder, that of Stanley was softer, and that of Jiashili was soft. The strawberry fruit treated with Wangdefeng and calcium protein was sweet, the fruit treated with Wofute and Batian was sweet, that treated with Jiashili was sour and sweet, and that treated with Stanley was slightly sour. The fruit treated with calcium protein, Wofute and Batian showed strong storage resistance. Strawberry plants treated with Batian, Wangdefeng, Stanley, and calcium protein showed stronger growth, and strawberry plants showed a semi-opening pattern. The yield of strawberry treated with Wofute was highest (17 400 kg/ha), which was significantly increased compared with other treatments, followed by that treated by Stanley (13 140 kg/ha).
