发布:cgzhc   发布时间:2019-05-27   浏览次数:224    [] [] []
Name of achievement: Four cropping techniques for crops in high altitude Dryland
Intellectual property rights: 1 invention patent and 3 planting technologies.
Award-winning situation: selected as the leading technology of Yunnan Agricultural and Rural Department in 2018.
Analysis of social benefits and economic benefits: The technology has been extended to 2,000 mu in high altitude areas above 2200 meters in Huize and 500 mu in Tianshentang (2320 meters above sea level) in South China. The effect of increasing income and saving cost is obvious. The technology was implemented in Huize and Nanhua counties from 2009 to 2018, with an average output value of more than 5,000 yuan per mu. It has practical significance for farmers in poor mountainous areas to get rid of poverty and become rich.
Outcome Profile:
This achievement makes full use of the interlacing and collocation of different types of crops in time and space, chooses the characteristics of relatively short growth period, relatively shade tolerance of varieties, cold tolerance, disease and insect resistance, and intensively utilizes natural resources such as light, heat, fertilizer and water at low latitudes and high altitudes to increase production and income. Key technology: Maize interplanting potatoes + autumn potatoes + green manure are implemented in the area of 2200 meters above sea level in our province. In northeastern Yunnan, spring potatoes are the first crop in March, maize is the second crop in early April, autumn potatoes are the third crop after spring potatoes are harvested in July, and green manure or radish are the fourth crop in early August. In southwest Yunnan, spring potatoes were planted in January, maize and radish intercropped in early May, radish harvested in July was the second ripening, maize harvested in September-October was the third ripening, Chinese cabbage, buckwheat and black pumpkin were planted after radish harvested in July, and the fourth ripening was harvested in December.
