Hancheng became the largest pepper production base in China and returned to hancheng city, Shaanxi Province, which is famous for its "Dahongpao" peppers at home and abroad. After eight years' efforts, the "100 million pepper bases" have recently passed the provincial acceptance test. So far, hancheng city has become the first county (city) with standardized pepper base in China, and it is also one of the largest pepper production bases in China. Hancheng is the hometown of Sima Qian. Zanthoxylum bungeanum was planted as early as six or seven hundred years ago. 1985, the municipal party Committee and municipal government decided to seize the advantages of Dalin products, make full use of mountainous areas and terraces, and build a "hundred-mile double-thousand-square-plant pepper base" according to local conditions. By August this year, 2,370 plants of Zanthoxylum bungeanum have been planted in hancheng city, and the annual output of Zanthoxylum bungeanum has soared from 1 1,000 kg to 2 million kg. Large-scale planting of Zanthoxylum bungeanum has brought huge economic income to farmers. This year, the income of Zanthoxylum bungeanum is 28 million yuan, and the per capita income of the city's agricultural population is 1 10 yuan, accounting for 20% of the city's per capita net income. There are 129 households in the main pepper producing area, and there are more than 1000 households with an annual income of more than 5,000 yuan. Farmers call pepper "Jin Doudou". There is also a saying in the countryside that "there are a hundred peppers in the house, and the annual income is 1000". Because most peppers are planted on ridges, the double-layer production of peppers and grain is realized, and the land interest is increased by 30-40. At the same time, Zanthoxylum bungeanum has effectively improved ecological conditions and farmland microclimate. According to the investigation of northwest forestry college in Hancheng pepper area, the root system of pepper effectively controlled the collapse of ridge and reduced soil erosion, with an effect of 60%. Compared with the pepper-free area, the average wind speed decreased by 30.25%, the relative humidity of air increased by 4% and the evaporation decreased by 25.7% in the growing season. 15, the contents of nitrogen, phosphorus and potassium in the whole pepper soil were higher than those in the neglected area by 3%, 87% and 127 respectively. 9%。 The large-scale planting of Zanthoxylum bungeanum has also promoted the development of agricultural science and technology. In recent years, the national, provincial, prefectural and municipal forestry scientific and technological personnel have worked together to overcome nine pepper research topics, among which the research results of biology and comprehensive management of red pepper have passed the expert appraisal and occupied a leading position in China. The annual income of a "red belt" in Baili forest belt of our city is over 100 million yuan. Every year in mid-August, the charming smell of pepper wafts from the Baili pepper base. According to the production measurement of the Municipal Agriculture and Forestry Bureau, the total output of "Dahongpao" peppers will reach 4.5 million kilograms this year, which is the best year in history. This "red belt" of pepper wrapped in shallow mountainous areas will bring more than 654.38 billion yuan in income to our city. "Dahongpao" Zanthoxylum bungeanum is a famous historical specialty in our city and is known as "China Famous Pepper". Since 1980s, Zanthoxylum bungeanum has been regarded as the main tree species for afforestation, and more than 30 million Zanthoxylum bungeanum have taken root and sprouted in barren hills, slopes, sparse ridges, ridges, roads, ditches and other cultivated land. The large-scale planting of Zanthoxylum bungeanum has inserted soaring wings for rural areas, especially shallow mountainous areas. Last year, the total output of Zanthoxylum bungeanum reached 3.5 million kilograms, the economic income was 85 million yuan, and the annual per capita income of Zanthoxylum bungeanum in rural areas of the city reached 336 yuan. There are more than 4,000 farmers in shallow mountainous areas, and the annual income of pepper alone exceeds 10,000 yuan, with the highest exceeding 10,000 yuan. The output of Zanthoxylum bungeanum in our city accounts for one-eighth of the whole country, and it is the largest and most profitable Zanthoxylum bungeanum production base in China. The sustained and efficient development of pepper in our city benefits from the popularization and application of science and technology. In our city, the research and production of pepper are carried out simultaneously. Low-yield forest transformation and pest research have always been in the leading position in China. After most of Chinese prickly ash entered the full fruit period, the comprehensive utilization and development of Chinese prickly ash made a breakthrough. The "Zanthoxylum bungeanum essence" developed by scientific and technical personnel fills a gap in the development of Zanthoxylum bungeanum products at home and abroad. "Zanthoxylum bungeanum essence" has been widely used in domestic medicine, chemical industry, food and other industries. Pepper deep processing brings more than 20 million yuan (Hancheng) to our city every year.
