Using biogas liquid as the top dressing of “spring shoots fertilizer” and “summer shoots fertilizer” for fruit trees can increase the fruit-bearing rate of fruit trees by 5%, increase production by about 20%, enhance quality, and increase sweetness by 0.5~1%. Fertilization principle: The amount of application is different for different fruit tree ages, and the biogas liquid is generally used during the growing period.Fertilization method: Apply “summer shoots fertilizer” (biogas liquid) in early May, and “autumn shoots fertilizer” (biogas liquid) in early July；

Fertilization method: Apply “summer tip fertilizer” (biogas liquid) in early May, and “autumn tip fertilizer” (biogas liquid) in early July; adult trees mainly apply flower-preserving fertilizer (biogas liquid) before flowering and fruiting, and strong fruit fertilizer (biogas liquid) during the young fruit period. At the drip line around the canopy, open a full round or half-moon ditch with a width of 30 cm and a depth of 35 cm. If the soil quality is poor, the depth of 50 cm is appropriate. Use 100~150 kg of biogas residue per plant, and apply part of the phosphate fertilizer appropriately to cover the soil in a slightly convex shape to prevent Stagnant water.Foliar fertilizer spraying can also be used to supplement nutrition during the flowering and fruiting periods. During the flowering period, use 100 kg of clarified biogas liquid to 300 kg of water (1:2~3), and spray directly into the foliage (leaf back). During the fruit enlargement period, use 100 kg of clarified biogas liquid to 100 kg of water (1:i), and spray directly into the leaves and fruit surfaces, 2~3 times a month. Foliar fertilizer spraying is best in the evening on a sunny day.
