The earliest and concentrated western apple tree species introduced in Yunnan. Rosaceae apples are deciduous trees. Temperate fruit trees. Jin Shuai, also known as the Golden Delicious, originates in the United States. In 1910, it was first introduced by Japan to Dalian, China. In 1940, Zhao Tongren, a native of Zhaotong, bought 150 strains from Chengdu, Sichuan, and planted it in Zhaotong County. Today, the fruit and technology station in the Zhaotong area still contains more than 70 normal fruit trees planted in the same year. The variety is suitable for cultivation in areas with colder and less rain, with an average annual temperature of 9°C-11°C and an optimum rainfall of 700 mm or less. The fruit matures in early September. With high yield and stable production characteristics. Jin Shuai average weight 180 grams, oblong. Fruit grown at low altitude is flat and round. Peel yellow green background, golden yellow after maturity. Fine meat, sweet taste, aromatic, suitable for fresh food, easy to produce fruit rust, will be hair after storage.

The National Institute of Fruit Research of the Chinese Academy of Agricultural Sciences identified Zhaotong as the most suitable area for growing apples throughout the country. Compared with northern apple production areas,

Zhaotong Apple has four major advantages: First, ecological advantages. From the perspective of climatic conditions, there are no cold winters, no summer heat, small annual differences, poor daily conditions, adequate light, moderate rainfall, and abundant light, heat, and water resources. This is the most suitable area for apple production. As it is located in the Yunnan-Guizhou plateau, the ultraviolet rays are strong, the temperature difference between day and night is large, and the accumulation of organic matter is faster, which greatly benefits the growth of apples. In terms of production conditions, the two counties in Zhao and Lu belong to major agricultural counties and have clean air and no industrial pollution. The development of pollution-free apple production has unique natural conditions. The second is quality advantage. Thanks to its unique natural environment, the apple produced is bright in color, crisp in flesh, moderate in sweetness and acidity, rich in sap, and rich in flavor. It has won many provincial high-quality fruit titles and the second national agricultural expo award. Zhaotong apples are in the three southwestern provinces, Guangdong and Guangxi. , Southeast Asia is famous. Third, the advantage of early maturing, Zhaotong apple has a month earlier than the northern region, the characteristics of the apple in the north when the apple is not mature, Zhaotong matured on the market, the early maturing species in the first half of July that mature, late maturing varieties mature in mid-September, sales The time has a larger market space and market competition advantages than the north. The fourth is location advantages and the market is vast. Zhaotong City is located at the junction of the three provinces of Yunnan, Guizhou and Sichuan. Due to climatic factors, these provinces and cities basically do not produce apples. Compared with the domestic apple production areas such as Shandong and Shaanxi, Zhaotong has geographical advantages and has established a fixed consumer market for many years of sales. The apples produced can be exported to Sichuan and Chongqing to the north and Guizhou and Hunan to the east. Hubei, south Guangdong, Guangxi. In addition, south-eastern Southeast Asia can also achieve field-to-table dining in only three days. Zhaotong Apple's sales to Hong Kong, Thailand, Myanmar, Vietnam and other countries, the establishment of the ASEAN free trade zone, Zhaotong Apple sales to provide a broader market.

In order to take advantage of Zhaotong’s natural resources, help farmers get rid of poverty as quickly as possible. In 1989, the Ministry of Agriculture designated Zhaotong as a high-quality apple production base in the south of China. In 1996, Yunnan Province designated Zhaotong as a provincial high-quality apple production base. Since the bases were listed, the production of apples has received unprecedented attention. From the prefectural commissions to the cities and counties, the apple production has been considered as a major category of structural adjustment of the agricultural industry. It has been incorporated into the internal management of agricultural production at all levels of government departments and Proceed to study. Firstly, the leading group for the construction of apple bases was established in the two cities and counties of Zhaoshi and Lu, and through the formulation of fruit development plans, administrative regulations and policies and measures, administrative functions and economic adjustment methods were used to strengthen the leadership of apple production and construction. The second is to expand the planting area in Zhaotong, Tucheng, Saiyu, Leju, Shouwang, Xiaolongdong, Beizha, Mengquan, Sujiayuan and Ludian’s Taoyuan, Yandong, Wenping, and Izun. Develop scale production. Thirdly, a large number of varieties were introduced and updated, and more than 30 new varieties were introduced. Through screening, Red Fuji, New Red Star, Jonagold, Shensha, 2001, Red King, and US No. 8 were selected. Lots of varieties adapted to our district are actively organized to promote and apply. The Red Fuji line, the new Red Star, and Jonagold have replaced the old varieties of Jin Shuai, Guo Guang, and Marshal, and gradually formed a reasonable mix of early, middle and late maturity. The implementation of the base construction work effectively promoted the development of the Zhaotong apple industry.

Laser Distance Meter

Laser distance measure is a very convenient tool for various types of applications in industries, construction and house decoration. Laser distance meter is a very useful device which gives accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, infrastructures, gardens, roads, and many other applications requiring accurate results for distance , area and volume measurement.
