Pear tree autumn tube three strokes
High switching
For the new high, longevity, autumn water and other varieties with poor performance traits, we must carry out high access, change varieties, and improve quality. Buds can be planted before the beginning of October and branches after the middle of October. Longer yields can quickly restore production, while the original old varieties in the tree can also have some production. Usually 3 years old, 15 or more buds; 5 year old trees have more than 50 buds. Immediately after grafting, a new high-fat membrane mother liquor was applied to seal the grafted joints and increase the survival rate of the scions.
Fertilizer management
Those who have not completed the autumn basal fertilization before falling leaves must complete it before the land is frozen. Fertilizer selection is mainly based on farmer's fertilizer containing more organic substances, accounting for more than 90% of the total amount of fertilization. This is the basic fertilizer for long-term supply of various nutrients for pears. Due to the slow decomposition of organic fertilizers and long fertilizers, the root system of pears is sparse and the performance of fertilizers is slow. Therefore, appropriate available nitrogen fertilizers, phosphate fertilizers, and potash fertilizers should be applied. The application amount of fertilizer should be determined according to the age of the tree, the size of the canopy, the nutritional status, the load, etc. Generally, the mature pear trees each apply 35-50 kg of organic fertilizer, 1-1.5 kg of superphosphate, and 0.4-0.5 kg of urea. Fertilization mainly includes annular furrows, radial furrows, and whole garden applicators. The ring groove is to excavate an annular groove at the outer edge of the crown projection, with a groove width of 30 cm and a groove depth of 40-50 cm. The gutter is applied to the trunk as the center and digging along the direction of the horizontal root extension, generally 4-6, the width of the groove is 30-45 centimeters, the depth is 40-50 centimeters, and the distance from the trunk is 1-1.5 meters. The depth of the ditch gradually increases from the inside to the outside. Deeper, narrower inside and outside, this method has fewer roots and is suitable for adult pears.
Post-harvest management
Root fertilization. Root can be used + root irrigation to induce the absorption and utilization of various trace elements in the soil. Foliage top dressing. The type and amount of foliar fertilizer, potassium dihydrogen phosphate, urea 0.3-0.5%, "new high fat film", once every 10 days, 3-4 times in a row, in the early evening spray absorption, fertilizer effect is high. Do a good job of autumn trim. After the fruit is harvested, the forgotten shoots that have not stopped growing are picked up and the dense shoots are removed. Immediately after pruning, smear “wound-resistance and anti-corrosion film†to protect the growth of wound healing tissue, infestation with preservative rot bacteria, soil protection, rainwater pollution, freeze protection, and prevention of chapped wounds.
