Abstract

The invention discloses an ecological cultivation method and mode in a North-west Hunan mountainous area. The method comprises following steps of: A, distributing all modules of the ecological cultivation method; B, selecting pig breed feeds provided by a farm; C, performing solid-liquid separation and fermenting pig slurries: firstly performing solid-liquid separation prior to fermentation of pig manure and then adding myriophyllum elatinoides for fermenting solid manure after separation; D, purification of biogas slurries and reduction in nitrogen content: utilizing a straw and myriophyllum elatinoids system to remove harmful substances of biogas slurries and decreasing nitrogen concentration of biogas slurries; E, production of non-pollution tea and rice: utilizing tea and fertilizer sources of rice as principal base fertilizers and performing physical control over tea and rice pests; and F, purification of tail water: adopting myriophyllum elatinoid wetlands as a tail water purifying system in order to ensure up-to-standard release of tail water. The mode is composed of a pig farm, a tea garden, a septic tank, a straw purifying pond, myriophyllum elatinoid wetlands and a paddy field.The ecological cultivation method in the North-west Hunan mountainous area is simple and conveniently operated at low cost and is capable of completely controlling breeding pollution and increasing economic income of farmers.

Description

technical field [0001] The invention relates to the field of ecological agriculture in mountainous areas in northwestern Hunan, more specifically to a high-efficiency ecological agricultural method of breeding + planting, and also relates to a mode of ecological farming in mountainous areas, especially suitable for mountainous areas in northwestern Hunan. Background technique [0002] The mountainous area of ​​Northwest Hunan is located in the northwest of Hunan, bordering Guangxi in the south, Sichuan and Chongqing in the west, and Hubei in the north. The mountainous area in northwestern Hunan belongs to the Wuling mountainous area, which is a typical "old, young, frontier, and poor" area, and it is a contiguous economically underdeveloped area in the country. In 2010, the GDP of the northwestern mountainous areas of Hunan Province was only 13% of the province's total, the per capita GDP was only 53% of the province's total, the local fiscal revenue was only 9.7% of the pro...
