Preparation method of plant nutrition substrate for anti-flushing ecological blanket

Abstract

The invention relates to a preparation method of a plant nutrition substrate for an anti-flushing ecological blanket. The plant nutrition substrate can be filled in the anti-flushing ecological blanket for providing nutrients for the plant growth, and the number of microorganisms in a slope protection base material in increased. The preparation method comprises the following steps that 1, a mixture A is prepared; 2, a saturated water-retaining agent B is prepared; 3, the nutrition substrate is prepared, the following parts are weight parts, the saturated water-retaining agent B is totally added into the mixture A, and the full stirring is carried out. The method solves the technical problems of low final greening rate and lack of sufficient nutrition and moisture in the plant growing process as a large amount of surface layer covering soil is taken away through rainwater flushing.

Description

technical field [0001] It is used in the fields of ecological slope protection engineering and ecological restoration engineering. Background technique [0002] Anti-shock ecological blanket is a new type of slope protection material introduced from abroad in recent years. While preventing water erosion and soil loss of river embankments, it can also achieve the effects of slope ecological restoration and landscape greening. Our country's research work on it has just started, and there is a big gap compared with foreign countries. [0003] In actual engineering construction, due to the complex local soil moisture, the survival rate cannot be guaranteed, which eventually leads to low plant survival rate, and the effect of slope greening and ecological restoration cannot be achieved. These disadvantages mainly include: ① The rainwater washes away the nutrients that are scattered in the ecological blanket to supply the plants during construction, resulting in the lack of nutr...

AI Technical Summary

Problems solved by technology

[0003] In actual engineering construction, due to the complexity of local soil moisture, its survival rate cannot be guaranteed, which eventually leads to low plant survival rate, and the effect of slope greening and ecological restoration cannot be achieved.

These disadvantages mainly include: ① The rainwater washes away the nutrients that are scattered in the ecological blanket to supply the plants for growth during construction, resulting in the lack of nutrients during the plant growth process, and the root system cannot penetrate the ecological blanket and take root in the soil

②Drought weather leads to low germination rate of seeds

③The soil in some construction areas is dense and hard, which is not conducive to the rooting and growth of plants
