Movable cultivation device suitable for solar greenhouse and multi-segment cultivation method for fruits and vegetables

Abstract

The invention discloses a movable cultivation device suitable for a solar greenhouse and a multi-segment cultivation method for fruits and vegetables. By the adoption of the multi-segment cultivation method combining middle and low-segment cultivation with long-segment cultivation in the solar greenhouse, the lighted rate of fruits and vegetables at the rear end, especially the middle lower parts of the fruits and the vegetables, is increased, and the yield of the fruits and the vegetables is increased. Meanwhile, as the low-segment cultivation time is short, the probability of diseases and insect pests is reduced. Moreover, the distances between the fruits and the vegetables of different cultivation segments are adjusted by adjusting the distance of the movable cultivation device, so the land utilization rate in the greenhouse can be increased, and the yield of the fruits and the vegetables is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural engineering, and in particular relates to a movable cultivation device suitable for a solar greenhouse and a multi-stage cultivation method for fruits and vegetables. Background technique [0002] With the development of modern agriculture, the construction level of modern solar greenhouses continues to improve, the height of greenhouses continues to increase, the three-dimensional space of greenhouses continues to expand, and the internal lighting conditions of greenhouses continue to improve. Therefore, how to make full and reasonable use of the internal three-dimensional space of greenhouses and sunlight energy to realize solar greenhouses Ultra-high yield has become an urgent problem to be solved in modern agriculture. [0003] At present, all kinds of fruits, vegetables and flowers need to be planted in greenhouses when they are produced in industrialized plugs or potted plants. In solar...

AI Technical Summary

Problems solved by technology

This utility model mainly solves the problem of complex structure and difficult disassembly and assembly of the existing cultivation bed

However, the cultivation bed is erected on the ground of the greenhouse through columns and cannot be moved, and is more suitable for seedling cultivation

[0004] Some greenhouses use fixed culture racks for soilless cultivation. For the convenience of harvesting and pruning, the row spacing is wide (1.5m), the land utilization rate is low, and the planting density of fruits and vegetables is low, such as generally 2‐4 per m 2 , the cultivation of fruits and vegetables is also a long-term cultivation, so that the lower the light receiving rate of the leaves of the fruits and vegetables closer to the back wall in the later stage of cultivation, thereby reducing the yield of fruits and vegetables

Chinese utility model patent CN200920173076.9 discloses a multi-layer multi-stage close-planting cultivation device. The device includes a planting cover plate, and equidistant planting holes are arranged on the planting cover plate. Although the device can make full use of the greenhouse space and increase crop planting Density, but the sunlight received by the lower plants is limited. In order to ensure the normal growth of the plants, artificial light sources, such as LED lights, should be used to supplement the light.
