Precautions after pear harvest

1. Do not apply high-concentration fertilizers within 15-20 days after picking the pears. Within 15-20 days after harvesting is the recovery period of tree vitality. When the vitality of the tree body is not restored, the application of high-concentration fertilizer will destroy the normal life activities of the tree body, and it is easy to produce physiological leaf fall.

2. Do not use chemical weeding in the orchard within 15-20 days after the pears are harvested before the vitality of the tree is restored, especially not spraying weeds with glyphosate. After the weeds are sprayed with glyphosate, they will be formed in order to survive. Secondly, the weeds dying after being sprayed with glyphosate increase the surface area of ​​the pear orchard exposed to the sun, which affects the water absorption of the pear trees, causing physiological water loss and leaves falling.

3. Avoid spraying high-concentration pesticides at noon high temperature within 15-20 days after the pears are harvested to avoid scalding the leaves.

4. Farmers who have conditions after pear harvesting can cover the underside of the pear trees with grass, green rice stalks and other straws.

5. After picking the pears, spray the nutrient solution on the leaves in time, that is, 1 g 2.4-D with 50 kg of water, plus 0.3% urea and 0.3% potassium dihydrogen phosphate. Spray once every 10~15 days, spray 2~3 times continuously.
