Characteristics: Yulu Pear has inherited the unique meat quality, delicious taste, no slag, red fruit, etc., which is unique to Korla Pear. It overcomes the small pear, large heart, low edible rate and fruit shape. The shortcoming is a high-quality, resistant, well-tolerated Korla fragrant pear-type large fruit new variety. 1. Fruit traits: Large fruit, average fruit weight 236.8g, maximum fruit weight 450g; fruit nearly spherical, fruit shape index 0.95. The fruit surface is smooth, delicate and waxy, and has good water retention. Yang faces a blush or dark red longitudinal stripe. The peel is yellow-green when harvested, yellow after storage, and brighter in color. Thin skin, small fruit; edible high (90%). Flesh white, crisp, no slag, very few stone cells, extra juice, sweet and fragrant, good taste; soluble solids content of 12.5% ​​to 16.1%, total sugar 8.70% to 9.80%, acid 0.08% to 0.17% , sugar acid ratio 68.22 ~ 95.31? 1, the quality of the extreme. The fruit is resistant to storage and can be stored for 4 to 6 months in natural clay caves and can be stored for 6 to 8 months in a constant temperature freezer. 2. Biological characteristics: The saplings have a strong growth potential. The germination rate is high (65.4%), and the branching ability is medium. The grafted seedlings generally have a 3-4 year result. After 2-3 years of high tree accessibility, they are easily flowered, have a high rate of fruit set, high yield, and stable yield. Shanxi Jinzhong area in early April early flowering, full bloom in mid-season, fruit ripening period at the end of August in early September, can be eaten in the middle and early August, fruit development period of about 130 days, early November leaves, vegetative growth period of about 220 days. 3, tree adaptability and resistance: strong adaptability of the tree, strict requirements for the soil, resistance to rot is stronger than the pear, pear and pear, second to snow pear and Ci pear; resistance to brown spot and Pear, snow pear, etc. are the same, stronger than Yali pear, Jinhua pear, and second to pear. The resistance to powdery mildew is stronger than that of pear and snow pear. The ability to resist black heart disease is moderate. The main pests are pear wood mealworm, mealworm, and fruit borer. Fourth, cultivation points: 1, suitable medium density planting, plant spacing generally 2-3m4.0m is appropriate. Uses a stem-shaped or spindle-shaped tree. Pay attention to the application of techniques such as early branching and sculpting to ease the vegetative growth of the tree and bring about early results. 2. This variety is easy to grow and has a high rate of fruit set. It requires timely thinning and fruit thinning. During the fruit period, attention should be paid to the management of water and fertilizer, reasonable loading, and improvement of fruit quality. The yield control in the full fruit period is appropriate from 2000 kg to 3000 kg. 3, The fruit skin is thin and tender, pay attention to improve the quality of harvesting and packaging. When the cave dwelling is stored, the initial temperature of the pit is minimized to extend the storage period. 4. The amount of pollen is small and should not be used to pollinate trees. Therefore, when setting up a garden, it is necessary to pay attention to the allocation of at least two pollination varieties that can pollinate each other.
