Problems solved by technology

[0007] The above-mentioned existing technologies are all soilless cultivation methods in which ceramsite is used in conjunction with nutrient solution, other substrates, and special devices. The common problem with them is that ceramsite cannot be used as an independent cultivation substrate, and at the same time, nutrient solution cannot be adsorbed on Ceramsite interior

Abstract

The invention belongs to the field of planting flowers in gardens, and in particular relates to a ceramsite flower nutrient cultivation substrate which simultaneously provides sufficient nutrients in the growth period of flowers and a preparation method thereof. The main body of the present invention is ceramsite, and ceramsite is immersed in nutrients, complexing substances and coating slow-release substances. The ceramsite is light clay ceramsite; the nutrient substance is sodium humate HA-Na; the complexing substance is at least Including one of disodium edetate EDTA‑2Na, sodium EDTA‑4Na and pentasodium diethyltriaminepentaacetate DTPA‑5Na; coating sustained-release substances include gluing agents and polymeric things. According to the present invention, the ceramsite has the characteristics of large specific surface area, loose and porous inside, and can accommodate a large amount of water and nutrient elements. The air in the internal pores of the ceramsite is extracted through a decompression and vacuum device, and then the nutrient solution is injected to make the nutrient solution adsorb on the ceramsite. The slow release inside the ceramsite makes the ceramsite support and nourish flowers at the same time.

Description

technical field [0001] The invention belongs to the field of planting flowers in gardens, and in particular relates to a ceramsite flower nutrient cultivation substrate which simultaneously provides sufficient nutrients in the growth period of flowers and a preparation method thereof. Background technique [0002] Ceramsite is widely used in soilless cultivation of flowers. It is clean and beautiful. Generally, it is mixed with peat, sand, vermiculite, perlite, etc. in proportion. Soil cultivation, etc. The basic structure of the circulating soilless cultivation device is composed of a cultivation bed, a liquid storage tank, a circulation pump, a liquid supply and discharge device, etc., and the device is complex. The basic structure of siphon soilless cultivation consists of a flower pot (planting pot), a closed liquid storage tank and a siphon tube. The nutrient solution is automatically sucked into the flower pot from the liquid storage tank through the siphon tube, and ...
