The effect of applying biogas fertilizer to planting pear trees is good.
Using biogas fertilizer to grow pear, the flower bud differentiation is good, the shoot is neat, the leaf is thick and green, the fruit is uniform, the glossiness is good, the sweetness is high, and the tree potential is enhanced, which can improve the pear tree's resistance to ring disease and black heart disease, increase the per unit yield by 10%, and save 50% of fertilizer investment.
For young pear trees, biogas manure was applied once a month, biogas liquid 10kg was applied to each tree, and biogas residue 10kg was applied to each spring shoot fertilizer. Adult hanging fruit trees, in order to produce fixed fertilizer, mainly to base fertilizer. Base fertilizer accounts for 80% of the total amount of fertilizer applied in the whole year, which is generally carried out during the dormant period of pear trees in early spring, digging radial ditches around the trunk, applying biogas dregs 50~100kg per plant, replenishing 250g compound fertilizer, and covering soil after application. Pre-anthesis fertilizer was applied 10-15 days before flowering, biogas liquid 50kg was applied to each plant, 50g urea was added, and the roots were sprinkled. The first application of strong fruit fertilizer was one month after flowering, each plant was treated with biogas residue 30kg or biogas slurry 50kg, 100g compound fertilizer was applied and ditched deeply. For the second time, two months after the flower blossom, the method of applying fertilizer was the same as the first time. Huanyang fertilizer was applied after fruit harvest, biogas liquid 30kg was applied to each plant, 50g urea was added, and sprinkled on the root. The application of postharvest fertilizer should avoid causing autumn shoot and autumn bud growth.
Biogas fertilizer to grow pears should be properly supplemented with chemical fertilizer and other organic fertilizers. Adult hanging fruit trees need 300kg biogas fertilizer to meet the nutritional needs, and the effect is better when root application is combined with foliar fertilization.

The most important thing for the high yield of pear trees lies in the flower tube.
1. Fertilizer and water management if insufficient nutrients affect fruit setting and young fruit expansion during flowering, urea is applied 20 days before flower bud germination, and the amount of fertilizer is generally determined according to tree age, tree potential, yield and nutritional status in the first half of the year. Spray 0.20% 0.50% boron at anthesis and after anthesis

The technique of high grafting and changing head of planting pear trees in autumn
In the production of grafting time, the high grafting and replacement of pear trees in a large area is generally carried out from early August to late September in autumn, that is, from summer shoot growth to autumn shoot growth. This stage of grafting has the advantages of high survival rate, low cost and good effect, which usually takes only one year.
