Embodiment Construction

[0039] The technical solution of the present invention will be further described in detail below through specific embodiments and accompanying drawings.

[0040] The decomposition process of the litter layer in the northern coniferous forest in my country is slow, and the return of nutrients from the plants in the ecosystem to the soil is slow, which restricts the realization of ecosystem service functions and leads to the decline of the coniferous forest ecosystem in the northern region. Growth and development are also severely affected. Such as figure 1 As shown, the experimental research shows that the decomposition of coniferous forest litter in northern my country is affected by the characteristics of the coniferous forest itself, and the decomposition speed is relatively slow. It is also affected by the dry and cold climate (temperature, humidity) and soil environment (such as pH) and the effects of animals and microorganisms in the soil. On the one hand, differences in ...

Abstract

The invention relates to a method for decomposing boreal litter in coniferous forests for improving ecological service functions, which adopts physical, chemical and biological means to regulate the micro-ecological environment of litter layers in coniferous forests, accelerates the decomposition of litter and improves the physical and chemical properties of soil surface properties, in order to achieve the purpose of improving the service function of the coniferous forest ecosystem. The invention is beneficial to improving the soil structure, increasing soil nutrients, improving the water conservation capacity of the litter layer, etc., thereby enhancing the potential ecological service function of the coniferous forest and promoting the healthy and sustainable development of the northern coniferous forest ecosystem.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a decomposition method of boreal coniferous forest litter for improving ecological service functions. Background technique [0002] Litter occupies an important position in the forest ecosystem. The natural decomposition of litter is an important link in the nutrient cycle of the forest ecosystem. The decomposition speed of litter will greatly affect the growth and development of the forest, the community stability and sustainable development of forests. The soluble substances produced by the decomposition of the litter layer are the direct source of forest soil fertility. A large number of litters in the forest area cover the surface of the forest land. Only by decomposing into absorbable minerals can they return to the soil and be absorbed by plants. Realize the cycle of forest ecosystem. Through research, it is found that the main components of com...
