High quality Pear Variety-Huangjin Pear

The golden pear was bred by a cross between the new height and the 20th century. It was introduced into China by South Korea in the 1990s and is suitable for growing in the middle and lower reaches of the Yangtze River and the Huaihe River basin. The variety has strong growth potential, more open tree posture, green-brown one-year-old branches, large and thick leaves, oval or oblong leaves, sharp and dense serrated leaf edges, and yellowish green leaves on tender shoots. The fruit is round and slightly flat, the pericarp is yellowish green, the bagged fruit is golden, transparent, the pericarp is thin, the fruit spot is large and sparse, it is very beautiful, the average weight of a single fruit is 350 grams, the pulp is fine, tender, crisp, there are no or very few stone cells, juicy, unique flavor and fragrance. The content of soluble solids is 14%, the fruit growth period is about 150 days, and it matures in mid-September. Strong resistance to pear black spot and scab. Higher requirements for fertilizer and water conditions, should be equipped with more than 2 pollination varieties, varieties should be selected new high, abundant water, 20th century, love, emerald and so on.

1. Fertilizer and water management. The golden pear has high requirements for fertilizer and water, and the land with high topography, good soil structure and fertile land should be selected for planting. It should be re-applied base fertilizer, 5000-6000 kg per mu of rotten pig barnyard manure and 100,150kg phosphorus-potassium compound fertilizer, appropriate interplanting of green manure and legume crops, topdressing of nitrogen, phosphorus and potassium fertilizer, and topdressing of pre-flowering, spring shoot prosperity and fruit expansion. Foliar fertilizer spraying should be considered according to the growth needs, and the drainage and irrigation system should be smooth and timely irrigation and drainage.

2. Flower and fruit management. The pollination varieties should be allocated properly, 2-3 pollination varieties should be allocated in each garden, pay attention to the flower-fruit, leaf-fruit ratio, keep 1 fruit per inflorescence, and the leaf-fruit ratio should be kept at 40:1. Beware of the phenomenon of big and small years, the yield per mu in the full fruit period should be controlled at about 3000 kg. In order to improve fruit quality and economic benefits, attention should be paid to bagging management, double-layer paper bags should be used in time after fruit setting, external irritation should be minimized, and the bottom of the bag should be torn open 10-15 days before harvest to improve the smoothness of the fruit surface.

3. Shaping and pruning. Three main branches were used to improve the spindle or spindle tree. The number of main branches (large fruiting branches) per plant is 12-15, and the main branches extend uniaxially. All the small and medium-sized results were pulled horizontally. In the growing season, remove the long branches and competitive branches, and adjust the angle of the upper branches in time in summer and autumn. Winter pruning is still dominated by thinning and angle adjustment. Because the fruit quality of the general branch group decreased after 2 years, the upper back branches should be flattened and cultured into fruiting branches, and attention should be paid to the cultivation of reserve branches in appropriate parts, so as to increase and maintain the yield of trees in full fruit stage.

4. Pest control. ⑴ does a good job of overwintering and clearing the garden. The fallen leaves were treated by centralized incineration and deep burial. ⑵ fruit trees should spray 50 times of stone-sulfur mixture 1-2 times before sprouting in order to kill overwintering eggs. In order to do a good job in the prevention and control of diseases and insect pests during the growing period of ⑶, pesticides with low residual effect should be used, such as cypermethrin lipids and biological agents, Bt, insect growth regulator thiourea 3, cypermethrin, moth aphid, polyantimycin, agricultural resistance 120, Fuxing methyl topiramate and so on.
