Three-dimensional combined temperature control and light control breeding bed

Abstract

The invention discloses a three-dimensional combined temperature control and light control breeding bed, which comprises a supporting and adjusting upright post, a multi-layer culture bed and an internal circulation water and nutrient supply and cold water running irrigation system, wherein the culture bed comprises a bottom tank which is connected with the internal circulation water and nutrient supply and cold water running irrigation system and in which nutritive water is held; a layer of mesh base membrane is arranged above the nutritive water; the bottom tank is covered by a bacteria separation cover plate; the bacteria separation cover plate is provided with directional sowing holes; the mesh base membrane is attached below the bacteria separation cover plate; devices such as a temperature and humidity sensor are arranged in the culture bed; and each device is in point-to-point wireless connection with a control center. Water temperature of the culture bed is adjusted and controlled by using underground water water-cooling running irrigation and the culture bed is recycled; better temperature reduction and temperature insulation effects are achieved; a relatively stable constant temperature environment is provided for culture of rice stock seeds; and by using the multi-layer combined breeding bed, the three-dimensional combined temperature control and light control breeding bed has the advantages of compact structure, space saving, easiness and convenience in operation and contribution to large-scale production and use.

Description

Technical field [0001] The invention relates to the field of agricultural cultivation facilities, in particular to a three-dimensional combined temperature control and light control breeding bed. Background technique [0002] "Food is the heaven for the people, and planting is the first for agriculture." Rice is one of the most important foods, and its production has a vital impact on people's livelihood. In the history of modern rice breeding, the dwarfing of rice varieties from the late 1950s to the early 1960s and the three-line hybrid rice matching in the 1970s are two important milestones. In order to achieve the purpose of increasing yield, the main focus at this stage is to use the hybrid advantage of rice subspecies to cultivate super-high-yielding varieties. However, the number of seeds obtained by hybridization is limited and cannot be promoted on a large scale. Seed cultivation must be carried out again to obtain a large number of original rice seeds. However, in the...

Problems solved by technology

However, the number of seeds obtained by hybridization is limited and cannot be promoted in a large area, and seed cultivation needs to be carried out again to obtain a large number of original rice species

However, in the process of seed cultivation, its excellent genetic character is easily affected by factors such as geographical environment, climate and pests and diseases, so it is difficult to reproduce a large number of excellent purebreds.

Especially in the critical period of seed trait formation, a relatively stable constant temperature environment is required, but it is difficult for existing cultivation systems such as seedling boxes to meet its requirements
