The specific method of operation is to dig a ring ditch with a depth of about 40 cm and a width of about 30 cm at the drip of the canopy, and apply high-quality mixed fertilizer, human and animal manure, and ash, and apply fertilizers such as urea and superphosphate. Then cover the soil, the amount of fertilizer should account for 50% of the year. Each tree can be applied to manure, animal manure or compost, 250 kg, urea, 0.5 kg, superphosphate, 1.5 kg, and 2 kg of cabbage. One to two days after fertilization, each fruit tree is watered with 100-150 kilograms to facilitate fertilizer dissolution and facilitate fruit tree absorption. Fruit "post-harvest" fertilizer should be completed within one month after fruit picking.
After the fruit is harvested, the “post-harvest†fertilizer is applied.
After the fruit is harvested, the fruit tree is weak, and its root system enters a new growth peak. In this case, it is necessary to timely apply the fertilizer in a timely manner so that the tree body can be restored to benefit the results of the next year. At the same time, entering the cold season, the application of organic fertilizer is also conducive to winter cold fruit trees.
