Buoy culture device for simple agricultural greenhouse

Abstract

Provided is a buoy culture device for a simple agricultural greenhouse, relating to the buoy culture device. A support body is of a ladder-shaped structure from the top to the bottom. A disc body (3) is placed in each ladder. Each disc body (3) is internally provided with a foaming board (24). Two ends of a telescopic water trough (5) are connected to long openings of two adjacent disc bodies (3) through clamping boards (2). A water inlet trough (1) is connected to a disc body (3) at the highest ladder. A disc body (3) at the lowest ladder is connected with a water drainage trough (4). The buoy culture device for the simple agricultural greenhouse has the following beneficial effects: multiple disc bodies are utilized for being connected with the telescopic water trough such that the disc bodies can directly replace a water bed; and therefore the purpose of reducing cost is fulfilled.

Description

[0001] 【Technical field】 [0002] The invention relates to a floating culture device, in particular to a simple agricultural greenhouse floating culture device. [0003] 【Background technique】 [0004] Known, floating seedling raising is a new seedling raising method, and it is that the foam tray that light seedling raising substrate is housed is floated on the water surface, and seed is sowed in the substrate, and rice shoot takes root and grows in the seedling raising substrate and can grow from substrate and A seedling raising method that absorbs water and nutrients in the water bed of the culture tray, and a method of raising seedlings that can absorb water and nutrients from the substrate and the water bed of the culture tray; there is also a method of using soft plastic pots to put the substrate with light seedlings on Water regularly in soft plastic pots or use a misting device to keep the seedlings hydrated. The aforementioned method has the advantages of reducing labo...

AI Technical Summary

Problems solved by technology

[0005] At present, most of the floating seedling technology is produced by foaming seedling trays. Add peat, vermiculite and other soilless culture substrates in the seedling trays, and put them into the water bed after sowing. There are small holes at the bottom of the seedling trays. It is conducive to the absorption of water and nutrients by the roots of plants; the water bed is filled with a certain depth of nutrient solution in a rectangular container, and the nutrient solution in the water bed is measured by computer control equipment, and then the nutrient solution in the water bed is measured. Replacement, and the recovered nutrient solution is used for secondary use after secondary deployment; however, for farmers, it is extremely expensive to build a greenhouse, and the use and maintenance costs are also unacceptable for first-time farmers; further, For crops with well-developed root systems or roots used as food materials, the used foaming seedling trays cannot be used again, and the soft plastic pots cannot be used again due to their extremely poor quality, so many discards will occur near many greenhouses. The waste foaming seedling trays and soft plastic pots; because the foaming seedling trays are usually discarded after use, the main reason is that the foaming seedling trays and soft plastic pots are extremely light in texture, the users are scattered, and the recycling and transportation costs are relatively high. High”, so this method also brings huge environmental pollution problems
