Reducing fertilizer is the harvested fruit fertilizer that is used after pears are harvested, which is commonly known as pear tree base fertilizer.
In order to enable mature pear trees, especially pears that have been in fruition for many years, to grow robustly and normally, and to maintain a sustained, high-yield, and high-quality tree vigor, the post-production management of pear trees should be focused on the following measures to increase production.
First, it is necessary to pay attention to the application of reduced fertilizer. At present, many farmers who grow pear trees have the habit of not applying fertilizer or reducing fertilizer. They believe that the effect is not significant, and that the defoliation of pear trees is 1 to 2 months earlier than usual, and some farmers’ pear trees will appear. Secondary flowering. So, why should we emphasize reducing fertilizer? The first reason is that the peak of the second new root system development of pear trees occurs from September to November. Second, the flower bud differentiation of pear trees is generally completed from June to October. During this period, sufficient fertilizer is applied to make pear trees. The root system has a good nutrition environment, can absorb enough nutrients in time, promote the development of flower buds intact, avoid premature leaf fall of pear trees, prevent pear trees in autumn and winter
"Second flowering." The fertilizing amount of pear tree reducing fertilizer should account for 60% to 70% of the total fertilization period. Some farmers may have high-content compound fertilizers that can be applied, but organic fertilizers should be promoted. Each farm can produce 8,000 kg of compost or fertilizer, and 60 kg of nitrogen fertilizer and 100 kg of phosphate fertilizer. Potash 20 to 30 pounds.
Second, we must plough the Liyuan ditch early. For some low-lying or sloping pear orchards, after the fruit is picked, it must be plucked in the winter to dig deeper, so that the winter lingering winter and ripening the soil. With the help of dumping the garden to clear the gutters, the water can be discharged in clear water and the dark water can be filtered.
Third, early prevention of pests and purify the living environment. Premature defoliation of pear trees is not only related to fertilizers but also related to pests and diseases. Therefore, the more deciduous pear gardens, the more potential pests, residues, rotten fruits, rotten leaves, and more likely to form the next year's pests and diseases. To this end, one must thoroughly clean up the residue of the pear orchard, the leaves and rotten fruit, and bring them out of the park for burning; secondly, scrape the old curled bark and dig out the more deeply buried pests; and thirdly, spray 75% of pentachlorophenol. Sodium 100 ~ 200 times liquid and the five wave beauty degrees lime sulfur and other pesticides.
