Abstract

The invention discloses a straw greening brick and a preparing method thereof. The straw greening brick comprises crop straw, animal waste, an inorganic complex, sodium polyacrylate, amino acid, polyamide epoxy chloropropane, ferrous sulfate, magnesium sulfate and borax. The straw greening brick has the advantages that the straw greening brick can provide rich nutrients for seed germination and plant growth, the straw greening brick can have certain water absorption strength due to the contained polyamide epoxy chloropropane and sodium polyacrylate, the straw greening brick is light in handfeel and loose in texture and has quite good water absorption property, water retention property and permeability, is good in forming and free of looseness and can be directly spread on the ground surface or half-buried in the ground surface, seeds and a brick body are press-formed at a time or the seeds are scattered in planting grooves, germination and growth can be directly realized after wateringor raining, the traditional turf spreading maintenance link is replaced, the rapid greening aim is realized, wind erosion can be rapidly stopped, the improvement of desertification saline-alkali soilis gradually realized, and land resources are saved.

Description

technical field [0001] The invention relates to the technical field of brick bodies and landscaping, in particular to a straw greening brick and a preparation method thereof. Background technique [0002] With the continuous development of society and the continuous improvement of the country's comprehensive national strength, the general public has a strong demand and urgent need for the improvement of the quality of life. With the continuous growth of the population, the per capita green area will decrease accordingly. Among them, this contradiction is becoming more and more prominent, especially in the life of urbanites, how to green the precious and limited space is the most concerned and important issue for people. In addition to greening the dedicated green land, people are also committed to greening large areas of public places such as open-air parking lots and squares. [0003] However, no matter the traditional brick is a solid brick or a hollow brick, the brick bo...
