Problems solved by technology

The composition is made into various seedling-raising nutritional pots by pressing, which solves the problems of large peat substrate, inconvenient transportation, and complicated configuration.
However, this invention does not consider the structural strength, and cannot meet the needs of large-area greening and agricultural modernization such as transforming deserts and environmental ecology.
[0005] In addition, the United Kingdom and Germany made seedling substrates from peat, fertilizers, trace elements and a small amount of sulfuric acid copolymer of ethylene oxide-phennonol, which can promote plant growth and are basically non-toxic, but the cost is quite high
[0006] All in all, since the curing agents in the above inventions all use polymer materials, and the toxicity of polymer additives needs to be considered, the above inventions neither consider structural strength nor compatibility with modern building concrete, masonry materials, etc. sexual issues

Abstract

The present invention relates to a composite material with plane nutrient action and structure strength and its technological process. Said composite material comprises 40-60% of peat, 10-30% of solidifying agent, 10-30% of adsorbing agent, 5-10% of nutrient additive and 0-1% of other additive. The composite material can be press-formed in the field, the seeds can be filled and then the formed composite material with seeds can be laid for use of can be stored for stand-by. Said composite material can be made into slurry material, and applied on the surface of various mouldings, then the seedscan be filled into the surface to make stereoscopic greening. Said ivnention possesses extensive application.

Description

technical field [0001] The invention relates to a formula of composite material with plant nutrition and structural strength. The invention also relates to processes for making such composite materials. Background technique [0002] With the development of science and technology and the survival needs of human beings, the protection of the ecological environment has been put on the agenda. The ecologicalization of gardens, buildings, and agriculture, especially the prevention of desertification, the reduction of sandstorms, and afforestation, have not only Professionals are concerned, and ordinary people are also very concerned. [0003] As we all know, substances with plant nutrition are generally referred to as fertilizers. It can be divided into chemical fertilizers and organic fertilizers in nature, and can be divided into solid fertilizers and liquid fertilizers in terms of form. However, generally speaking, plants cannot grow directly on th...
