For growing chestnut trees in summer, the following two fertilization methods can be used as reference:
Soil fertilization method: For chestnut orchards with thin, poor soil and severe fertilizer deficiency, the soil fertilization method produces better results. Dig a circular ring trench within the drip line of the chestnut tree canopy for fertilization, with a trench width of 25 cm and a depth of 20 cm. Apply 1 kg of superphosphate, 0.3 kg of urea, and 0.25 kg of borax per tree. When fertilizing, the urea and borax should first be dissolved in water, then applied in the trench, splashing water while fertilizing. After fertilization, promptly backfill the trench with soil to prevent nutrient volatilization. When fertilizing
If an appropriate amount of farmyard manure is additionally applied to enrich the soil, it has a good effect on promoting more chestnut yields the following year and reducing the rate of empty burs.
Foliar feeding method: This fertilization method is effective for chestnut trees on all types of soil in summer. Mix 0.3%-0.4%% urea solution, 0.3%-0.5%% monopotassium phosphate solution, and 0.3%-0.4%% borax solution, then spray the tree canopy before 9 AM or after 3 PM on a sunny day. Spray again after 10 days, and two consecutive sprays are sufficient. If heavy rain occurs within 10 hours after spraying, re-spray once to ensure the fertilization effect.
