Chenggong Baozhu Pear is produced in the Chenggong District of Kunming. It is the best fruit of the Mid-Autumn Festival and has the reputation of the King of Lizhong. “Zhenggong Baozhu Pear” has been cultivated for more than 900 years in Chenggong. According to legend, in the Song Dynasty, the monk Baozhu monk to the 鄯 鄯 (now Kunming) lectures, brought the Dali Sydney saplings produced in the Bohai Sea area, and grafted with a high-quality native pear tree produced by Chenggong, in the low latitude plateau unique to Chenggong. The natural climate of “no winter is cold, no summer is hot, dry and wet is clear, and the seasons are like spring” and basalt red soil is especially suitable for the cultivation of fruits. It has been carefully cultivated by local people. It is said that in the early years of the Yuan Dynasty, local officials in Yunnan tribute Baozhu pear to the court. The emperor ate a lot of praise, and he had to pay tribute every year. The place that gave birth to Baozhu pear was “chenggong”, and “Zhenggong County” got its name. .

Baozhu pear has been exported in small quantities and exported to Hong Kong and Macao. It has been cultivated for hundreds of years. It is said that a monk named Baozhu was cultivated from the field and grafted with local pear trees. Because of the high quality of the products, I used to be a tribute to go to Kyoto, and the origin of Baozhu Pear was named "chenggong". Planting distribution The average elevation of Chenggong County is 1900m, red soil or paddy soil. It is rainy in summer and dry in winter. The average annual precipitation is 800-1200mm, the annual average temperature is 14.9-15.3°C, the average annual sunshine hours is 2232 hours, and the frost-free period is 285 days. Baozhu pears are warm and cool, and have strict requirements on water quality, soil and climatic environment, so the suitable planting area is narrow. In Chenggong County, mainly distributed in the bath Tangshan - Duanjiaying Songshan - Fenghuangshan - Liwangshan - Xiaojianshan - Xiaoguanshan - Taibanshan and Ma Chimney Hill - Zhaojiashan - Mopanshan - Xiaoshishan - Wushan - Jianfengshan - Maanshan-Liangwang Mountain, two mountain ranges facing the Dianchi Lake, including Wujiaying Village, Wanxichong Village, Langjiaying Village, Duanjiaying Village and Zhaojiashan Village in Wujiaying Township, 50-100 years old tree 50%-70%; Wanxichong Village and Yujiaying Village cultivate the most, and the area and output account for 1/3 of the county; Majinpu Township and Qidian Township are new cultivation areas, with a tree age of 10-15 years. Nutritional value Vitamin C in pears is a healthy element of cardiovascular protection and heart disease patients. On November 21, 2009, the research results of American biologist Judes Lawes showed that immature or semi-ripe pears have anti-radiation effects. The ripening of pears requires a large amount of insolation, which can effectively absorb the rays in the sun. Recently, the Silicon Valley Fractional Office in the United States has used pears as the main anti-radiation item. They believe that the anti-radiation effect of pears is far greater than cactus and aloe vera, and it is more beautiful than the cactus. Its taste is sweet and flat, non-toxic, and has the effects of thirst, spleen and diarrhea, and stomach reflux. People who eat more pears are far less likely to catch a cold than those who don't eat or eat pears. Therefore, some scientists and physicians refer to pears as "all-round healthy fruits" or "general practitioners." Air pollution is now more serious. Eating more pears can improve respiratory and lung function and protect the lungs from dust and fumes in the air. The history of planting "Baozhu Pear" is to commemorate the cultivation of Gaochun Baozhu pear for hundreds of years. When it is said that Dali Kingdom, there is a sorghum Baozhu monk to the interpretation of the city (now Kunming), from Sydney to Dali brings Sydney saplings, after passing through with Chenggong Pear species are grafted and become a fruit. If you eat fruit, you will not forget to plant trees. This pear is called "Baozhu Pear" to commemorate Gaochun. Because of the high quality of the products, I used to be a tribute to go to Kyoto, and the origin of Baozhu Pear was named "chenggong". In 2009, the Quality Supervision Bureau of Kunming City of Yunnan Province examined and approved the Comprehensive Standard for Chenggong Baozhu Pear. The "Zhenggong Baozhu Pear Comprehensive Standard" consists of two parts. The standard is formulated with reference to national and local standards and related technical literature. It combines the actual situation of standardized production in Chenggong County. The technical content of the standard is objective and clear. Reasonable, the standard has strong scientific, advanced and operability. Delicious stuffed Baozhu pear Baozhu pear has a large skin, color such as jade, taste like glutinous rice, juicy and less slag, sweet and unique, is an excellent variety unique to Yunnan. It can also be done with other varieties of pears, but with less flavor. Peel the treasure beads, dig your heart and let it float in the clear water. Then prepare some kinds of ingredients such as pine nuts, lotus seeds, longan meat, ginkgo and glutinous rice produced in Yunnan, and peel the peeled fruits from these ingredients. At this time, we must use the same raw materials in Yunnan - Xuanwei ham! Like that year, Mr. Sun Yat-sen called for Xuanwei ham, the inscription "Drinking food and food", this allusion is familiar to everyone. Of course, you have to use other hams to accompany you, just to remind you that Xuanwei ham is made from the “Wumeng Golden Pig” which is raised in Yunnan Dashan. The feed and pig breeds used in other places are not guaranteed. So fragrant. Cut the ham into cubes, peel the prepared nuts, mix the ham, and steam on the fire. Slightly fry the Baozhu pear in the lard. It depends on the ability to master the heat. Don't over-cook it. You must blow up the golden color and you can't live. Of course, the end of the wind is best fried.
