Problems solved by technology

[0027] At present, common water and soil loss control measures generally have problems such as weak "three guarantees", long treatment time and high follow-up management requirements. Although the excavation cost of the trenches of the present invention is relatively high, the solution to water and soil loss is immediate and the control effect is excellent. The input-output ratio is good, and the comprehensive cost is not high

Embodiment Construction

[0062] The dense trench treatment method of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0063] (1) Determine the total capacity of the ditch according to the short-duration maximum precipitation

[0064] The total volume of the trenches per mu shall not be less than the total runoff formed during the maximum rainfall. In the design, the total volume of the trenches shall be determined according to the safety principle that the total precipitation of the storm is equal to the total runoff. According to the analysis of precipitation recorded in the history of western Fujian, the 3-hour maximum precipitation that occurs once in 10 years is set to 90mm [according to custom, the specifications and layout of the ditch are described in units of meters (m) and mu (666.7m2). illustrate].

[0065] The total designed volume of each mu of ditch V = 10-year 3-hour maximum precipitation h (mm) ÷ 1000 × 666.7 (m2) = 90 ÷ 1...

Abstract

The invention belongs to the field of water and soil loss management and ecological environment restoration, and particularly relates to a technical method for projects, soil fertilizers, plants and agriculture and the like, which is a new water and soil loss management mode with very strong capability of water and soil conservation and ecological restoration and capability of organically combining a complete rainfall infiltration project with a simple and efficient soil fertility cultivation measure through distributing horizontal jumping ditches in a high-density way, centered on improvement of soil fertility for water and soil loss characteristics.

Description

technical field [0001] The invention belongs to the field of soil erosion control and ecological environment restoration, and particularly relates to technical methods such as engineering, soil fertilizer, plants and agriculture. The organic combination of thorough precipitation storage and seepage engineering and simple and efficient soil fertility cultivation measures is a new model of soil erosion control with strong soil and water conservation and ecological restoration capabilities. Background technique [0002] At present, soil erosion is serious in many parts of our country, and the following methods are commonly used in the governance process: [0003] (1) Banned [0004] That is to say, to close the mountains for forest and grass cultivation in the designated areas, and completely prohibit all kinds of development and logging that are not conducive to soil and water conservation. Suitable for moderate and mild soil erosion control. [0005] (2) Sowing grass in sm...
