Cultivate weeding. The field will be shallowly ploughed 10-15 cm to achieve loose soil and reduce weeds and fruit trees to compete for nutrients.
Herbicides are weeded. When weeds grow to about 5 cm or weed with herbicides before flowering, labor can be saved.
Fertilize. In the second half of February, fertilization should be carried out in the first ten days of March. Fertilization should be carried out in strips or radial fertilization. The amount of fertilizer applied is determined according to the fruit yield and leaf nutrient status. Generally, pure nitrogen is applied to the fruit yield, and nitrogen, phosphorus and potassium are used reasonably. proportion.
Water management. Combined with fertilization and irrigation, it promotes the normal growth and development of the tree.
Disease prevention and control. Red spiders and yellow spiders should be placed before flowering. Regular inspection, the yellow spider development is half a month earlier than the red spider, and it is active on both sides of the main vein of the leaf back. When the average of each leaf reaches 2, when the red spider reaches 2-3, the low temperature period in March, the spray tree is large. The general disinfected and sterilized the insect population to within one head. After the temperature rises, check the insect mouth for more than 3 to 5 heads per leaf, spray insecticide 2 times, at intervals of 10 to 15 days, local damage can pick the central insect strain. The flower buds and the flower hummers are sprayed with the insects and the ground once in the beginning of March when the buds are white (ie, the size of the flower buds). Spray again at intervals of 7 days.
