Embodiment Construction

[0013] A kind of method utilizing sweet potato vine to control rocky desertification water and soil loss of the present invention is:

[0014] 1. Determination of root index: The root density is measured by excavating the section wall method, and a section with a certain depth is selected according to the characteristics of the rocky desertification soil according to local conditions, and the root density is investigated. use 100cm 2 A large ring knife × 10cm and a sampler 20cm × 10cm × 10cm are used to take samples in layers every 10cm along the soil profile, put the soil sample containing the root system in the soil sieve to select the root system, use a vernier caliper to grade and count the diameter of the root system, and measure Its root length, root surface area and biomass.

[0015] 2. Rainfall, runoff, and sediment measurement: rainfall is measured with a siphon diary rain gauge; runoff is calculated with a SW40 diary water level gauge combined with a 45° triangular ...

Abstract

The invention provides a treatment method for water and soil loss, and relates to a method for treating stony desertification water and soil loss by using ficus tikoua. An objective of the invention is to provide an effective method for treating water and soil loss. The method for treating stony desertification water and soil loss by using ficus tikoua comprises: 1, measuring root system indexes, including using an excavation section wall method to measure root density, according to characteristics of stony desertification soil, selecting a section in a certain depth according to local conditions, and conducting an investigation on the root system density; 2, measuring rainfall, runoff, and sediment, including measuring rainfall capacity by a siphonic daily rain gauge; 3, measuring soil physical properties, including using an aerometer method for measuring soil mechanical composition; 4, measuring soil chemical properties, including using a potassium dichromate external heating method to measure organic materials; 5, calculating soil erosion durability indexes; 6, planting ficus tikoua, that is, planting in the last ten-day of May to June in a rainy season.

Description

technical field [0001] The invention relates to a method for controlling water and soil loss in rocky desertification by using sweet potato vines. Background technique [0002] Rocky desertification is a land degradation process with exposed rocks and desert-like landscapes caused by the interaction between the fragile ecosystem of karst mountainous areas and unreasonable human economic activities. [1] . It has been recognized that karst rocky desertification is based on a fragile ecological geological environment, driven by strong human activities, degraded by land productivity as its essence, and marked by the emergence of desert-like landscapes [2] . [0003] Sweet potato vine, also known as Guoshanlong, is a wild evergreen creeping perennial woody vine and berry plant of the genus Moraceae [3] . The plant can grow in all seasons, and its growth is prosperous in spring, summer and autumn. It is a positive plant that likes light, and it is also an excellent plant for d...
