Embodiment 1

[0021] The Hongfeng Lake Demonstration Area in Qingzhen, Wujiang-Beipanjiang Fenshuiling, Guizhou Province, is a typical moderate rocky desertification area in karst mountainous areas. The applicant conducted a pilot project of rocky desertification control in this area, and adopted the following control methods:

[0022] ——For sloping cultivated land with a slope of 15°-25°, promote land gradient technology, build stone ridges and slopes and biological hedges, and adopt water-saving agricultural technical measures such as horizontal slope planting, horizontal ditch planting, and plastic film mulching to grow food Or commercial crops, pastures, supporting the construction of mechanical farming roads and working access roads to improve farming conditions. Reducing water and soil erosion through the construction of biological hedges, harvesting leaves or straw to return to the field, and pruning branches to make firewood can not only increase the organic fertilizer of cultivated ...

Abstract

The invention relates to a treatment method for moderate stony desertification in a karst mountain area. The treatment method includes the steps that a land terracing technology is popularized in a slope cropland, a forest for water and soil conservation is constructed on the periphery, high-yield commercial fruit-bearing forest-crystal grapes are developed on the lower portion of a peak cluster slope and part of depressions, and gold pears are developed between grasslands which are good in condition on the upper middle portion of a slope body and a sparse forestland. Through a grassland construction technology, a grassland improvement technology and a high-quality forage planting and managing technology, by the utilization of the mode of combining an intercepting ditch, a desilting basin and a small reservoir and the mode of combining a floodwater drainage canal, a water inlet ditch, a desilting basin and a reservoir, water resources are developed and utilized. An ecological medicine industry base and an ecological grape industry base are established. A machine is used for digging a well, underground water is taken, a high-position water pool is constructed at the high point of a control area, the water pool and slope surface water pool field pipelines form an irrigating net, and by the adoption of an irrigation technology, an early vegetable base is established. Through the treatment method, moderate stony desertification of the karst mountain area is effectively treated, water and soil loss is weakened, the rock exposing trend is restrained, and society and economy are coordinately developed.

Description

technical field [0001] The invention relates to a control method for moderate rocky desertification in karst mountainous areas. Background technique [0002] The distribution area of ​​exposed and semi-exposed karst areas in China is more than 1.3 million square kilometers, accounting for 13.54% of the total land area. The 550,000 square kilometers of karst in southern China centered on the Guizhou Plateau is the largest and most intensely developed area of ​​tropical and subtropical karst in China and the world. Karst environmental and ecological problems are very typical and representative in the country and the world sex. The special environment and ecology have produced various effects on natural conditions, human survival and economic and social development: on the one hand, the evolution of geological history driven by dissolution, erosion and collapse has formed colorful tropical and subtropical karst landscapes, Occupying a prominent position in the world karst, it...
