Biogas fertilizer is applied to pear trees. The flower buds are well-differentiated, the shoots are neat, the leaves are thick green, the fruit is uniform, the luster is good, the sweetness is high, and the tree vigor is enhanced. It can improve the ability of pears to resist ring rot and black heart disease and increase the yield per unit. Save 50% on fertilizer investment.
Pear saplings are planted once a month with biogas fertilizer. Each plant applies 10 kilograms of biogas slurry, and the spring shooter adds 10 kilograms of biogas residue to each plant.
Adult fruit trees are planted to produce fertilizer, mainly based on basal fertilizer. Base fertilizer accounted for 80% of the total amount of fertilization in the whole year. Generally, it is carried out during the dormancy period of pear trees in early spring. The radial grooves are excavated around the trunk, and 50 to 100 kilograms of biogas residues are applied to each plant, supplemented with 250 grams of compound fertilizer and covered with soil after application.
Before flowering, it was applied 10-15 days before flowering. Each plant had 50 kg of biogas slurry, 50 grams of urea added and roots applied.
Strong fruit fertilizer, the first application in the first month after the flower Xie, 30 kg of biogas residues per plant or 50 kg of biogas slurry, plus 100 grams of compound fertilizer, deep ditch. The second time in the two months after the flower replenishment, the amount and method of fertilization were the same for the first time. Also, after the fruit was harvested, the Yang fertilizer was applied. Each plant had 30 kg of biogas slurry, 50 grams of urea and roots applied.
Biogas fertilizer and pears should be properly supplemented with chemical fertilizers and other organic fertilizers. Adult fruit-bearing trees need 300 kilograms of biogas fertilizer to meet their nutritional needs. The combination of root application and foliar fertilizer is better.
