Soilless cultivation apparatus for vegetable labyrinth, and cultivation method of soilless cultivation apparatus

Abstract

The invention belongs to the technical field of agricultural cultivation, and particularly relates to soilless cultivation apparatus for a vegetable labyrinth. The soilless cultivation apparatus comprises at least two frame bodies, and at least one set of labyrinth-shaped cultivation assembly supported on the frame bodies, the labyrinth-shaped cultivation assembly comprises through cultivation pipes forming a labyrinth shape, and plugs which are arranged at two ends of the cultivation pipes and can improve a liquid level in the cultivation pipes, cultivation holes are formed in the cultivationpipes, and the cultivation pipes communicate with extension pipes through the plugs. The invention further provides a soilless cultivation method using the apparatus. The soilless cultivation methodcomprises the following steps: 1, preparing a nutrient solution; 2, preparing a seedling fixing substrate; 3, planting seedlings; and 4, performing management. According to the cultivation method, thecultivation materials are scientifically designed and manufactured, and nutrients of a special formula are applied in a matched manner. On the basis that the ornamental interest of vegetables is improved, a nutrient solution depth of the cultivation pipes is increased by about 15 mm, a transplanting survival rate is increased by about 12%, the unit yield is increased by about 17%, and thereby thecultivation method is ecological, environmentally friendly, and wide in application prospect.

Description

technical field [0001] The invention belongs to the technical field of vegetable cultivation, and in particular relates to a soilless cultivation device of a vegetable labyrinth and a soilless cultivation method using the device. Background technique [0002] Soilless cultivation is a new agricultural technology that uses light materials such as peat or forest leaf humus and vermiculite as substrates to fix plants, allowing plant roots to directly contact nutrient solution for indoor crop cultivation. Among them, vegetable soilless cultivation is more common. . In many vegetable science and technology demonstration gardens, soilless cultivation adopts a three-dimensional rack cultivation method with liquid supply through pipes to make better use of the greenhouse space and enrich the display of varieties. However, the plane layout of most cultivation racks is "L-shaped" or "line-shaped", and the labyrinth type is rarely seen. [0003] Someone invented a labyrinth (CN201420...

AI Technical Summary

Problems solved by technology

[0003] Someone invented a labyrinth (CN201420541138.8), the main body of the labyrinth is a column, and a cultivation cup is arranged on the side of the column instead of a pipeline cultivation; Design a soilless cultivation rack (CN201921070867.9) connected with liquid injection at the same time and a soilless cultivation rack (CN201820042969.9) connected in series with cultivation pipes. Although pipeline cultivation is adopted, the cultivation pipe is affected by the diameter of the connecting pipe , the liquid level in the tube is not high, which affects the sufficient water in the cultivation cup, thus causing the plants to wilt due to lack of water
