Three-dimensional water culture method and system and hydroponic plant thereof

Abstract

The invention discloses a three-dimensional water culture method and system and a hydroponic plant thereof. The three-dimensional water culture method comprises the steps that a plurality of plants are planted on one side of a pipe sectional bar with the preset axial length on a workbench; the pipe sectional bar is erected on a tower, and a preset included angle is formed between the pipe sectional bar and the ground so that one sides of the plants can face outwards; a nutrient solution with the preset depth is formed inside the pipe sectional bar through nutrient solution circulating devices connected with the two ends of the pipe sectional bar. According to the method, on the basis of the good combination of the nutrient solution film technology and the three-dimensional culture method, the perpendicular space can be effectively utilized, the yield per unit area is high, and the requirement of a root system for oxygen can be well met. The overall water culture system is low in cost and manufacturing cost and convenient to produce and facilitates large-scale application and popularization.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a three-dimensional hydroponic method, a hydroponic system and hydroponic plants. Background technique [0002] Soilless cultivation is a modern cultivation technology that uses light materials such as peat or forest leaf humus and vermiculite as seedling substrates to fix plants, allowing plant roots to directly contact nutrient solutions. [0003] Since the nutrient solution is used to provide the nutrients needed for plant growth during the cultivation process, it is freed from the limitation of the soil, and can basically avoid the troubles of common diseases and insect pests. Compared with the traditional soil planting method, no pesticides are used in the planting process, and the produced fruits have extremely high economic value. [0004] The existing hydroponics methods mainly include the following: [0005] The first is the deep flow method (DFT), where t...
