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, peat, fertilizers, trace elements and a small amount of sulfuric acid copolymer of ethylene oxide-phennonol are used in the UK and Germany to make seedling substrates, 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

Embodiment 1

[0022] The composite material made by briquetting of the present invention is composed of the following weight percentages: peat 58.37%, sawdust 19.46%; Portland cement 6.49% calcium hydroxide (absolute dry) 6.49% phosphate rock powder 3.89% calcium magnesium phosphate fertilizer 1.30%; urea 2.60%; potassium sulfate 1.30%; composite trace elements 0.1%.

[0023] The preparation method of the above-mentioned briquettes is as follows: First, the peat produced in Laiyuan County, Hebei Province with an organic content of 60% to 70% is dried so that the moisture content is not higher than 20%, and the fineness after crushing is reached 10 mesh. Then, calculate according to the above weight percentage and weigh to obtain the following formula:

[0024] Name Weight Specification

[0025] Peat 45 kg 10 mesh

[0026] Sawdust 15 kg 0~10 mesh

[0027] Portland cement 5 kg

[0028] Calcium hydroxide (absolutely dry) 5 kg

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 seeds can 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 a composite material with plant nutrition and structural strength. 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, the ecologicalization of buildings, the ecologicalization of agriculture, etc., especially the prevention of desertification, reduction of sandstorms, and afforestation are not only Being cared by professionals, ordinary people are also very concerned. [0003] As we all know, the substances with plant nutrition are generally called fertilizers. It can be divided into chemical fertilizers and organic fertilizers in nature, and solid fertilizers and liquid fertilizers in form. Generally speaking, however, plants cannot be grown directly on fertilizers. Fertilizers need to be applied to the soil, and plants are ...
