Embodiment 1

[0015] 1. A horticultural cultivation substrate prepared from construction waste, including construction waste, peat, decomposed straw, wood vinegar, and water-retaining agent.

[0016] 2. The components and proportions of the horticultural cultivation substrate prepared by construction waste are: the volume of construction waste is 0.3m³, the volume of peat is 0.3m³, the volume of decomposed straw is 0.1m³, the volume of wood vinegar is 0.05m³, and the volume of water retaining agent is 0.01m³.

[0017] 3. The construction waste is made by crushing waste bricks into particles with a particle size of less than 5mm, and then calcining at 500°C for 24 hours, then adding 0.1M hydrochloric acid to adjust the pH to 6.0; the decomposed straw is made of corn straw After the broken length is less than 10mm, add cellulase, hemicellulase, peroxidase and protease to ferment and decompose. The weight ratio is cellulase: hemicellulase: peroxidase: protease: broken straw = 2:2:1:1:50; the w...

Abstract

The invention belongs to the technical field of soilless culture, in particular to a horticultural culture substrate prepared through building garbage. A preparation process comprises the steps of breaking the building garbage into granules, performing treatment, uniformly compounding the treated building garbage with plant ash, thoroughly decomposed straw or thoroughly decomposed livestock and poultry excrement and urine, wood vinegar and a water retaining agent, and maintaining moisture equilibrium of 40%-60% for 2-3 days, so as to obtain the horticultural soilless culture substrate for use.According to the horticultural culture substrate prepared through building garbage disclosed by the invention, a new treatment way is provided for the building garbage, the horticultural culture substrate prepared through building garbage has favorable efficacy of water retention and fertilizer retention, and normal growth requirements of horticultural plants can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and relates to a horticultural cultivation substrate prepared by using construction waste as a main raw material. Background technique [0002] In protected horticulture production, soilless cultivation technology has been widely used in the factory production of flowers, horticulture and its seedlings. As the basis of this technology, the cultivation substrate has always been one of the focuses of research and development. From the early vermiculite, rock wool, river sand, to the later ceramsite, perlite, peat, etc., among them, peat is the matrix with the most demand and the best application effect, and the annual output of the world is about 90 million m 3 However, the over-exploitation of peat has caused great damage to the environment. Therefore, the development of new substrate materials has become the key to the continued development of soilless cultivation techniques. In re...
