Liquid and air storage type soilless culture apparatus

Abstract

A liquid storage and air reserve type soilless cultivation apparatus comprises an outer bucket and a pan-shaped screen aperture grid core arranged on the bottom of the outer bucket, the grid core is provided with nutrient solution and an air layer, the outside of the net core is filled with cultivation base material, the surface of the grid core is covered by a fine-mesh shape or silk-cloth shape substance for supporting the base material, its bottom, lateral surface and upper portion are provided with non-seepage water vent pipe for connecting with the air space in the grid core, the supporting ring on the bottom of the outer bucket is connected with a spigot-and-socket communication pipe.

Description

Technical field: [0001] The invention relates to a liquid-storage-gas-storage type soilless cultivation device, which is used for cultivating vegetables, dwarf fruit trees, flowers, etc., and can be used alone for small-area family planting or combined for large-scale production. Background technique: [0002] Soilless cultivation replaces the soil environment with the artificially created root system environment of the crop. In addition to meeting the needs of the crop for mineral nutrition, water, and air, these environments can also be controlled and adjusted artificially, so that the products produced by it can be controlled and adjusted regardless of the quantity. In terms of quality, it is better than soil cultivation. Soilless cultivation has an outstanding effect in overcoming continuous cropping obstacles caused by the accumulation of pest base in the soil, soil secondary salinization, soil physical and chemical deterioration, and root autotoxicity secretion, which ...

Problems solved by technology

However, there is still no soilless cultivation system suitable for my country's national conditions and suitable for large-scale production, which makes my country's soilless cultivation area only more than 300 hectares, which cannot be compared with European developed countries

The soilless cultivation systems developed in my country's cities or agricultural demonstration areas are mainly based on the introduction of foreign systems, mainly rock wool cultivation and hydroponics. These soilless cultivation systems have a large investment and low overall output value. They mostly rely on tourism income to make up for production losses.

However, the organic ecological soilless cultivation developed in rural areas has not yet achieved standardization, especially the key technology of substrate fermentation, which is difficult to master, and the large amount of substrate per unit area, subsequent substrate treatment, residual liquid discharge and pollution of groundwater resources, etc. , have not been well resolved
