Soilless culture device and soilless culture method

Abstract

The invention relates to the technical field of agriculture. The invention aims to provide a modularized soilless culture device and a soilless culture method capable of effectively inhibiting pathogen transmission. The soilless culture device comprises a liquid storage tank, a supporting tank fixedly arranged above the liquid storage tank, and a field planting plate erected on the supporting tank, wherein the supporting tank comprises a tank body, end plates arranged at the two ends of the tank body and a supporting frame arranged in the center of the tank body and extending in the length direction of the tank body. According to the soilless culture device provided by the invention, a modular structure and a field assembly mode are adopted, so that the construction period is shortened, and as long as a field is available, the device can be used after being assembled so as to be very convenient to use. An ultrasonic atomization mode is adopted, so that the atomization degree of a culture solution is better, plant absorption is facilitated, and the aeroponic culture effect is improved. A culture solution disinfection filter is adopted to disinfect and kill the culture solution in real time, and meanwhile, separation strips are utilized to realize culture solution circulation, so that circulation dead angles are reduced, and plant diseases can be effectively inhibited.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a soilless cultivation device and a soilless cultivation method. Background technique [0002] Soilless cultivation refers to a plant cultivation method that does not use soil, but supplies nutrients needed for plant growth through nutrient solution or other substrates. It has the advantages of saving planting space, easy control of nutrients, easy management, and less pests and diseases. Hydroponics, Aeroponics and substrate cultivation are several major methods in the current soilless cultivation methods; aeroponics is to use a spray device to atomize the nutrient solution into small droplets and spray it directly to the root system of the plant to provide the water and nutrients needed for plant growth. It is a soilless cultivation technology, but because the aeroponic device requires many parts, and the domestic start is late, the development is slow, and the investment...

[0002] Soilless cultivation refers to a plant cultivation method that does not use soil, but supplies nutrients needed for plant growth through nutrient solution or other substrates. It has the advantages of saving planting space, easy control of nutrients, easy management, and less pests and diseases. Hydroponics, Aeroponics and substrate cultivation are several major methods in the current soilless cultivation methods; aeroponics is to use a spray device to atomize the nutrient solution into small droplets and spray it directly to the root system of the plant to provide the water and nutrients needed for plant growth. It is a soilless cultivation technology, but due to the large number of components required for the aeroponic device, and the late start and slow development in China, the investment in research and development has been insufficient in recent years, resulting in outdated corresponding equipment and facilities, which do not meet the development needs of agricultural modernization

For example: 1. The construction period of the aeroponic device is long, and the labor cost is relatively large

2. Due to the recycling of the culture solution in soilless cultivation, once the pathogen control is not in place, the disease will spread rapidly with the nutrient solution, seriously affecting the growth of the plant
