Grape irrigation fertilization technology
Fertigation is the most suitable fertilization method for grapes. The drip irrigation test of grapes in the brown earth area of ​​Daze Mountain, Pingdu City, Shandong Province (Yu Zhenzhou, 1988) showed that the average age of grapes aged 20 years was 1000 kg/mu, and drip irrigation was 4 to 5 times in the whole growing season. Mu, that is to meet the grape water requirements. In drought years or high-yield levels, the number of drip irrigation is not less than 10 times, and the irrigation quota is 7-10 square meters/mu. In brown soil vineyards with low P and K nutrient contents, the target yield is 1500 kg/mu. The recommended fertilization amount for the Shandong Provincial Soil and Fertilizer Station Irrigation Fertilization Research Group is: N5.0 kg, P20511.0 kg, K20 1.0 kg, The ratio of N, P205, and K20 is 1.0:0.7:1.4. In the case of partial fertilization in the late autumn of the first year, the irrigation and fertilization of the grapes during the following year is 4 to 5 times, and the nutrient concentration of the fertilizer is between 450 and 600 mg/l.
