In the summer, the Ya pear tree grows vigorously. This period is not only the fruit's rapid expansion period but also the flower bud formation period. Grasping the management during this period is not only related to the bumpy harvest of this year's pear fruit, but also related to the quantity and quality of next year's pear flower. . The management of this period focuses on the following three things:
First, fertilizer and water management
Based on the fertilization in autumn and winter, a flat nitrogen, low-phosphorus, and high-potassium fruit tree compound fertilizer was applied before flower bud differentiation from late May to mid-June, and the water was applied immediately after fertilization. The amount of fertilization should be based on the age of the tree, the vigor and strength of the tree and the number of results, according to the production of 100 kg of fruit each year, the need for pure nitrogen 0.5 kg, 0.25 kg of pure phosphorus, 0.5 kg of pure potassium as a benchmark to determine the optimum amount of fertilizer. In combination with spraying, foliar spray of 1% urea water, 0.3% amino acid compound fertilizer solution, and 0.2% potassium dihydrogen phosphate solution were used to supplement the tree nutrient and enhance the photosynthetic capacity of the leaves.
Into the rainy season, more rain, according to the soil water conditions appropriate irrigation, watering water should be poured, prevent flooding irrigation. After the heavy rain, we must promptly rule out the accumulation of water in the garden and prevent the roots from decaying due to rain soaking.
Second, pest and disease prevention
Focus on the prevention and control of "two diseases and four bugs", namely pear scab, ring rot disease, tenebrio molitor, pear wood worm, Cornell mealybug, and fruit borer.
Pear scab: always check regularly, timely detection and thorough removal of diseased leaves, diseased branches, eradicate the source; According to the timely injection of disease prevention and control, can be used 40% DuPont Fuxing 10000 times or 10% difenoconazole 3000 times .
Ringworm disease: available Hanbang 50% carbendazim 2000 times or 68.75% DuPont Epro 1200 to 1500 times liquid.
Tenebrio: 10% red storm (imidacloprid) 1500 times or 20% acetamiprid 3000 times + 4.5% beta cypermethrin 1500 times.
Pyramid: available 2.0% abamectin 3000 times + 4.5% beta cypermethrin 1500 times.
Conrad's whitefly: 40% chlorpyrifos can be used 1500 ~ 2000 times liquid + assisted to kill 1000 times, or 205 Konzerthai powder 2000 times.
Locust insects: Available diflubenzuron 3 1000 ~ 1500 times + 4.5% beta cypermethrin 1000 ~ 1500 times solution or 1% Methionine 1800 times solution.
Third, summer trim
Summer pruning is a supplement to winter pruning, and doing a good job of summer pruning will help control tree vigor, promote flower formation and improve ventilation and light transmission. Normal results of the tree, we must strictly control the branches and dense shoots on the backbone, comprehensive use of topping, folding tips, thinning branches, pull branches and other methods, adjust the tree branches of the tree potential and perspective, timely removal of upright branches, cross branches, Disease and disease branches.
Nuts are a group of cleistoses that have a hard skin and contain a single seed. It is the essence of plants, rich in nutrition, containing higher minerals, vitamins, oil and protein, eating more can promote growth and development, increase physical fitness.
