Rooting: Watering the roots of 1 to 2 years old fruit trees, using an earthy earthen bowl around the perennial fruit trees, and 15 to 20 cm in height, to prevent watering, save water, and achieve watering concentration. , to promote water penetration. After pouring the water on the first day, the roots were cultivated the next day and the soil was cultivated 15-20 cm to protect the roots. 3. Irrigation: For drip irrigation orchards, drip irrigation or sprinkler irrigation can be used. 4. The sulcus on perennial fruit trees, from 50 to 70 cm away from the fruit tree, a small ditch around the fruit tree, the water poured into the ditch, the water will seep to the root, was absorbed by the roots.
