Cultivation device and cultivation system

Abstract

The invention provides a cultivation device and a cultivation system. The cultivation device comprises a casing and a planting portion, wherein the casing comprises an accommodating cavity, the side,away from the ground, of the casing is a planting plate, the planting portion is arranged on the planting plate and used for planting plants, the planting plate is recessed toward the ground and is provided with a water drainage hole, and the water drainage hole is communicated with the accommodating cavity. In the cultivation device, a nutrient solution can flow into the accommodating cavity through the water drainage hole, and thus the nutrient solution in the accommodating cavity can be recycled or centralizedly discharged. The planting plate is recessed towards the ground, so that the excessive nutrient solution flows towards the middle to avoid the phenomenon that the nutrient solution flows to the ground. The technical scheme has lower requirements on the slope of the ground, the problem is solved that land is more difficult to level in the related art, and the installation and construction costs and maintenance costs are saved. In addition, the nutrient solution is collected into the accommodating chamber to be kept in a dark state, algae growth is decreased, the recovery rate is improved, and the recovery cost is reduced.

Description

technical field [0001] The invention relates to the field of cultivation technology, in particular to a cultivation device and a cultivation system. Background technique [0002] At present, soilless cultivation can avoid soil continuous cropping obstacles, save water, fertilizer, labor, labor, strong crop growth, high yield, good quality, can greatly expand agricultural production space, and is conducive to the realization of agricultural modernization. It is more and more popular at home and abroad, but the cost of soilless cultivation is mostly high. In related technologies, the cultivation strips are often used to flatten the ground and then set up the cultivation strips through metal supports, or to directly use foam boxes or substrate bags for cultivation in order to save costs. Drain directly to the ground or do not drain. The cost of using metal brackets is high, and the requirements for leveling the ground and the accuracy of construction and installation are also ...

AI Technical Summary

Problems solved by technology

The cost of using metal brackets is high, and the requirements for leveling the ground and the accuracy of construction and installation are also high. After construction deviations, it is easy to cause nutrient solution discharge or recovery difficulties, and even cause nutrient solution accumulation to soak the roots of the plants, resulting in root damage or even death. At the same time, The use of scaffolding cultivation reduces the space utilization rate. For the long-term cultivation of vine plants such as tomatoes and cucumbers, the number of falling vines will increase, which will increase labor costs. It will also cause a lack of ventilation in the roots, resulting in anaerobic respiration, which will affect the normal growth of plants.

In addition, direct exposure of the nutrient solution to light can easily lead to algae growth, block drainage channels, affect the recovery and recycling of nutrient solution, and increase the difficulty and cost of sterilization and disinfection
