Modularized indoor agricultural planting system based on gel matrix

Abstract

The invention discloses a modularized indoor agricultural planting system based on gel matrix. The gel matrix is prepared from the following raw materials in weight percentages: 0.5-2 parts of agarose, 0.5-2 parts of sodium alginate, 1-10 parts of nitrogen, phosphorus and potassium ion composite inorganic salt nutrient, 0.1-1 part of calcium, magnesium and iron ion composite inorganic salt nutrient, 0.05-1 part of a microorganism-inhibiting agent and 84-98 parts of water. The agarose has a concentration range of 0.5%-2%, the sodium alginate has a concentration range of 0.5%-2%, and the microorganism-inhibiting agent has a concentration range of 0.05%-0.1%. The gel matrix is clean, safe and non-toxic, releases excessive nutrients slowly and can be repeatedly used, such that the cost is saved. In the planting system, on the basis of each module unit for cultivating plants through the gel matrix, later-stage maintenance is reduced in cooperation with a light supplementing system and a water spraying system, front-end device investment in a traditional water circulation nutrient solution cultivation mode is not needed in the modular planting, large-range diffusion of plant diseases and insect pests among the plants due to a water circulation system is avoided, and refined management and control are realized.

Description

【Technical field】 [0001] The invention relates to the technical field of agricultural cultivation, in particular to a gel matrix-based modularized indoor agricultural planting system. 【Background technique】 [0002] Cultivation methods are divided into traditional agricultural soil cultivation and modern agricultural soilless cultivation; traditional agricultural soil cultivation is easily affected by many uncontrollable factors, resulting in low yield and high cost, such as complex and heterogeneous soil composition, easy to breed insects and mold ; a large amount of manual input for fertilization and watering in the later stage; natural conditions such as external light, heat, water, and soil are uncontrollable, etc.; at present, indoor agriculture has been developed on the basis of traditional agriculture, mainly soilless cultivation (nutrient solution circulating water Cultivation) method, through indoor light supplement, temperature control and ventilation system, water...

AI Technical Summary

Problems solved by technology

However, these hardware systems required for soilless cultivation require high initial investment, especially the water circulation filtration system, which needs to continuously filter and purify the tap water before adding various nutrient fertilizers to control the concentration of various nutrients in the water within an appropriate range, neither too high nor too high Cause plant burning, and the concentration should not be too low to cause plant fertilizer shortage

At the same time, it is necessary to prevent and control various plant diseases and insect pests in the circulating water, because the water circulation filtration system used in soilless cultivation is to place all the plants in the planting system in the same water circulation system, and the plants themselves have certain non-standard characteristics that may have Some pollution sources, if any one of the plants suffers from pests and diseases, it may contaminate all other crops in the system, causing a large amount of economic losses
