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 ditch management 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 trench according to the short-duration maximum precipitation

[0064] The total volume of the ditch per mu is not less than the total runoff formed during the maximum rainfall, and the total volume of the ditch is determined according to the safety principle that the total precipitation of the storm is equal to the total runoff during design. According to the analysis of precipitation recorded in the history of western Fujian, the maximum precipitation in 3 hours is set at 90 mm once in 10 years illustrate].

[0065] Design total volume of ditch per mu V = once in 10 years, the maximum precipitation in 3 hours h (mm) ÷ 1000 × 666.7 (m2) = 90 ÷ 1000 × 666.7 = 60 m3

[0066] (2) Determine the area, total length and total number of grooves according to the total volume of the g...

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 water and soil loss 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 cultivation measures is a new model of water and soil erosion control with strong water and soil conservation and ecological restoration capabilities. Background technique [0002] At present, soil erosion is serious in many places in our country, and the following methods are commonly used in the treatment process: [0003] (1) ban [0004] That is, in the designated area, the closure of mountains for forestation and grass cultivation is implemented, and all kinds of development and harvesting behaviors that are not conducive to soil and water conservation are completely prohibited. Suitable for moderate and mild soil erosion con...
