Description

Vertical hydroponic culture equipment

Technical Field

The invention relates to vertical hydroponic equipment.

Background

Compared with the traditional soil cultivation method, the water cultivation method has the advantages that the water cultivation method has higher productivity than the soil cultivation method, and the water cultivation method can accurately adjust the nutrition proportion at any time so as to ensure that the target crops can obtain the required nutrition most effectively in each growth stage, thereby achieving the maximum productivity. Second, hydroponics can be applied to many locations where soil cultivation is not appropriate, and various vegetables and fruits can be cultivated all year round even in jungles or soil-poor areas where they live in cities. Thirdly, the probability of various soil-borne insect pests and diseases is greatly reduced, and the final yield is improved. Fourthly, the water ploughing method needs less ploughing area and has no weed, and the cost of labor, maintenance and transportation can be reduced by automatic operation setting.

The most common hydroponic systems are based on horizontal configurations, which still require a planting area close to the soil cultivation method, and DWC (deep water cultivation; float deep water cultivation or raft), or NFT (nuclear technology liquid film cultivation or tube cultivation) hydroponic systems are all configurations using horizontal cultivation beds.

In the DWC system, the roots of the plants are immersed in a container or tank filled with nutrient solution, which is replaced or mixed when the concentration of the nutrient solution is below a certain level. One of the disadvantages of DWC is that it is difficult to obtain enough oxygen to maintain the health and operational efficiency of the roots because the roots are always immersed in a relatively static liquid, and thus additional increase of the dissolved oxygen in the water is required by continuous damage to the surface of the water or aeration of the air-inflating motor. Without aeration, the roots may become susceptible to rot due to excessive water immersion, resulting in retarded plant growth and reduced yield. Along with the increase of the air temperature, the dissolved oxygen in the water body is reduced, and the operation load of the aeration equipment must be increased.

In the NFT system, plants are planted in a covered long and narrow water tank or pipeline, nutrient solution only flows through the bottom of the pipeline shallowly, so that part of the root system can contact with water and be interwoven into a blanket shape to keep moist, and the upper part of the root system is exposed in the air. The root blanket like growth pattern efficiently absorbs water, air and nutrients as the plant matures, which is a major advantage of NFT over other hydroponic techniques. However, as the plant grows, the root system also grows vigorously, and the horizontal duct space is gradually blocked by the root blanket over time, thereby limiting the passing path of the nutrient solution water flow. In addition, many growers add microbial additives to the system which are beneficial to the growth and root development of crops, but the microorganisms can form a biofilm on the contact surface inside the pipeline, so that the water flow smoothness is affected.

Meanwhile, it is also difficult to change the design of the pipeline without causing water accumulation at the bottom in the pipeline. Finally, most basic NFT systems use a portion of the growing medium, such as foamed stone or rockwool, loaded into a growing cup or a growing mesh basin, and then placed on a pre-perforated pipe, once placed, the entire system is immobile or difficult to transport. In the above-mentioned hydroponic system, the crops are grown on the horizontal plane, so the cultivation area used is only a little smaller than that of the traditional soil cultivation method, and in this respect, the horizontal system is not an efficient choice in densely populated cities or places with high cost per unit land.

The vertical hydroponic system can increase the cultivation density by cultivating crops on the same vertical axis, thereby achieving the requirement of saving space. Vertical hydroponic systems allow growers to grow crops in a confined space where the growing area is needed, especially those types of crops that are forced to be abandoned in conventional cultivation systems due to the high operating costs and low efficiency of unit production. Many vertical cultivation systems simply stack horizontal pipes or planting trays in multiple layers and then deliver nutrient solutions in a centrally dosed mechanism. The main disadvantage of this type of system is still that the pipes are easily blocked by the root system, requiring frequent and cumbersome maintenance. None of these techniques make it desirable for many growers to transport live vegetables, which are rich in nutrients and taste and are growing, directly from the farm to the end point of sale or consumer, as exemplified by the system of patent No. US7,055,282B2.

The vertical hydroponic system using the tray as a cultivation container still needs to be a rainproof cover plate or a rainproof outer cover, otherwise, when the system is exposed in an open space outdoors, the rainwater can dilute the concentration of the nutrient solution in the system.

U.S. patent No. us8,327,582b2 is another example of the use of newer vertical hydroponic culture systems to grow plants in vertical growth tubes filled with culture medium. However, the design of the device is that the growing tube is completely filled with the cultivation medium, no additional breathing channel is provided, when the root system of the plant grows to a certain degree, the solid wastes metabolized by the root system and the plant can gradually occupy the space for even blocking the transmission of nutrients and oxygen, and an anaerobic zone in the tube can be easily caused, and the anaerobic zone can lead the roots to be anoxic and even rotten. This situation is reliably avoided by the release of earthworms into the system, which dredge the root system for breathing while removing decayed roots and other organic waste from the medium, but it is not always good to release such organisms as earthworms as a helper into a closed-cycle system. This system is designed for use in greenhouses and the lower part needs to be fitted with gutters to capture the recycled nutrient solution, such gutters are not suitable for outdoor open environments with strong wind and sun interference, in which case the water collecting gutters are prone to algae growth and the nutrient solution is subject to accelerated evaporation in strong wind and sun. In addition, in greenhouses, it is relatively easy to control or treat the conditions in which insects such as gnats and the like lay eggs using catchment gutters.

Many growers often use a seedling raising box with a transparent upper cover to raise new seedlings, and the new seedlings are transplanted into a hydroponic system to grow stably after the seedlings are strong enough. This provides a stable and high humidity environment for the young plants to grow and root initially, but it is labor and time consuming to operate and the transplanting process may result in slow development and even death of the seedlings due to the impact of environmental changes. A new mode of operation that can eliminate these two steps can save labor and time investments for amateur and professional growers.

From the analysis of scientific experiments, the density of the cultivation medium in the root zone can obviously influence the growth condition of plants, the root zone needs oxygen, the oxygen which can be obtained by the root system coated in the cultivation medium is much less than that of the root system without the medium coating, and the root system is easy to suffocate in thick and compact soil medium without enough water drainage capacity. Because the nutrient solution can last from top to bottom flow through the root zone and can not ponding lead to the fact the anaerobic zone, perpendicular cultivation system can provide more excellent air permeability, and the efficiency that the nutrition was absorbed to the root system is higher, and such system, on average, the nutrition absorption conversion rate is higher, so the nutrition of the addition of needs still less, and the plant also because can experience drought and waterlogging in turn, so can stimulate the root system and develop towards more places and promote whole growth vigor.
