Hua Niu Apple was planted in Tianshui City on 1925. 1956 Huaniu Village, Ershilipu Township, Maiji District, Tianshui City introduced seedling varieties such as Red Marshal, Golden Crown and Guoguang from Xiongyue Town, Liaoning Province 10. Under the guidance of technicians, 10 seedling varieties were successfully cultivated, among which Red Marshal was colorful. 1In the autumn of 965, the fruit farmers in Huaniu Village carefully selected two boxes of apples that had just been picked and gave them to Chairman Mao to show their admiration. After tasting it, Chairman Mao liked it very much. When I met Deng Baoshan, a celebrity in Tianshui who was then the governor of Gansu, I entertained him with Tianshui apples and praised him: "The apples in Tianshui, your hometown are really delicious!" Since then, the General Office of the Central Committee of the CPC has sent a special letter to thank the villagers of Huaniu Village on behalf of Chairman Mao, and Huaniu Village will also send a thank-you letter to the Xerox Tree Monument to commemorate it forever. In the same year, the red marshal cultivated by Huaniu Village was first shipped to Hong Kong for trial sale. In order to understand the trial sale, the technician marked the word "Hua Niu" in the upper right corner of the apple box with a pencil as a mark. The Hong Kong office sold "Hua Niu" Red Marshal to a British businessman, who in turn sold it to an American businessman. After a few bites, the "Hua Niu" apple became an instant hit. At that time, the Hong Kong newspaper said that there was a "flower cow country" in the northwest of China, which produced the best quality "flower cow" apples. Fruit shape, meat quality, sugar content and other indicators are better than the American ace apple "snake fruit", overwhelming world-famous brands. After the evaluation of Hongkong market, China "Huaniu" apple won the title of world ace. Traders from all over the world signed a three-year contract with China Export Office to buy "Huaniu" apples. The Fruit Research Institute of China Academy of Agricultural Sciences (New Red Star Development Group) said in the Preliminary Opinions on the Planting Division of New Red Star Apple in China that the price of "Hua Niu" apple produced by Tianshui is relatively high in the international market, and it is the most prestigious and abundant export commodity among the apples exported by China. Later, China officially took "Hua Niu" as the trademark of Apple and exported it in large quantities. From 65438 to 0974, the Ministry of Foreign Trade and the Ministry of Forestry officially identified Tianshui as one of the six major export producing areas of apples.

"Hua Niu" has created a well-known brand by virtue of its unique geographical advantages and efforts, and this well-known brand has won by solid quality. Researcher Xiu Deren, director of the Academic Committee of the National Agricultural Products Preservation Engineering Technology Research Center, believes that Tianshui's advantage is the "flower cow" apple, and no other place can compete with Tianshui. He suggested that Tianshui directly aim at the international market and build a "Huaniu" apple export base; Mr. Wang Jingyan, who is known as the "apple saint", believes that "Hua Niu" apple is the earliest brand in China, second only to the "snake fruit" in the United States in the world; Professor Chao Wuji, Secretary-General of Beijing Agricultural University and Grape Branch of China Agricultural Society, thinks: Tianshui is the largest cultivation area of new red star in Asia, and also the dominant production area in China, with great development prospects; Associate researcher Cheng Cungang, director of the Cultivation Office of china fruit Research Institute, said at the seminar on the development of the Loess Plateau in China's apple-dominated areas: China doesn't produce red star series, but what you produce is characteristic. Therefore, "Hua Niu" is the characteristic of Tianshui.
