Three-dimensional cultivation method for greenhouse crops

Abstract

The invention discloses a three-dimensional cultivation method for greenhouse crops. The method comprises the following steps: (1) building a greenhouse, wherein the front roof angle of the greenhouse is greater than 45 degrees; (2) building a trapezoidal planting table in the greenhouse, wherein the trapezoidal planting table comprises a plurality of steps, handrails are arranged on the two sides of the steps, and the steps and the handrails can all be formed by connecting a plurality of steel pipes of different lengths; (3) placing cultivation vessels on each step of the trapezoidal planting table, and filling a cultivation medium into the vessels; (4) planting photophilous plants in the medium and planting sciophilous plants in the ground below the trapezoidal planting table. The method has the beneficial effects that the greenhouse span is shortened, the front roof angle is increased, the sunlight receiving angle of the greenhouse is increased, the temperature of the greenhouse is increased, the crops planted on the inclined plane are gradient in height, the mutual shading rate is reduced, the planting density can be increased, the yield is improved, and a shady space is formed on the lower part of the greenhouse to plant the sciophilous plants.

Description

technical field [0001] The invention relates to the technical field of vegetable planting, in particular to a three-dimensional cultivation method for greenhouse crops. Background technique [0002] The use of greenhouses to grow vegetables is to artificially create a suitable ecological environment to grow vegetables, adjust market demand, and promote high-quality and high-yield vegetables. In winter greenhouse production in the northern region, the main problems are: ①The angle of the front roof is small and the temperature is low; ②The vegetables grow on the ground of the greenhouse, and the temperature and light are not in the best conditions; ③The number of plants planted on the ground is strictly limited , the density cannot be increased arbitrarily. [0003] In view of the above problems, it is necessary to propose an effective method to solve this series of problems. Contents of the invention [0004] The invention proposes a three-dimensional cultivation method ...
