Problems solved by technology

In the same growth period, when the light and other growth environments are consistent, the seedlings tend to grow excessively when the temperature is high, and the seedlings grow slowly in an environment with low temperature, resulting in relatively large differences in leaf area, biomass, and strong seedling index of seedlings in different layers. Large, uneven quality levels, reducing the qualified rate of finished seedlings, affecting the quality and emergence time of seedlings, resulting in production efficiency that cannot reach the predetermined goal;

Embodiment 1

[0037] The present embodiment 1 has adopted cucumber as a sample, and the greenhouse multi-layer seedling raising system is as follows: figure 1 As shown, there are five layers in total, and the specific seedling method is as follows:

[0038] (1) Put the matrix of peat: vermiculite = 2:1 into a 72-hole hole tray, and absorb water, sow cucumber seeds soaked in RO water for 6 hours in the hole tray, one seed per hole, sow The depth is 1cm, covered with soil, placed on each layer of the seedling raising shelf, each layer is 35cm high, watered thoroughly when the water content of the substrate is 50%, and the nutrient solution (EC between 1.5-1.8ms / cm, pH 6.0-7.0), and clear water at other times.

[0039] (2) Test the temperature and humidity change law of each layer as follows: Figure 2-6 shown by Figure 2-6 According to the analysis, the temperature of each layer is different at the same time. The first layer and the fifth layer can have a maximum difference of 5.7°C in th...

Embodiment 2

[0053] In Example 2, tomato is used as a sample, and the greenhouse multi-layer seedling cultivation system is as follows: figure 1 As shown, there are five layers in total, and the specific seedling method is as follows:

[0054] (1) Put the matrix of peat: vermiculite = 2:1 into a hole tray with 72 holes, and absorb water, sow tomato seeds soaked in RO water for 6 hours in the hole tray, one seed per hole, sow The depth is 1cm, covered with soil, placed on each layer of the seedling raising shelf, each layer is 35cm high, watered thoroughly when the water content of the substrate is 50%, and the nutrient solution is poured at the tomato seedling stage (EC is between 1.5-1.8ms / cm Between, pH is 6.0-7.0) mainly.

[0055] (2) Test the temperature and humidity change law of each layer as follows: Figure 2-6 shown by Figure 2-6 According to the analysis, the temperature of each layer is different at the same time. The first layer and the fifth layer can have a maximum differ...

Abstract

The invention discloses a light regulation method for a multi-layer seedling raising system in a greenhouse, aiming at the difference of the high temperature of different layers, through the production dissimilation setting of the light quality, to improve the large difference in the growth state of the seedling caused by the temperature difference phenomenon, to achieve the consistency of the morphological indicators of the finished seedlings, and to improve the qualified rate of the finished seedlings per unit area.

Description

technical field [0001] The invention relates to the technical field of plant lighting, in particular to a light control method for a multi-layer seedling raising system in a greenhouse. Background technique [0002] Stereo seedlings is an advanced seedling raising technology that uses multi-layered three-dimensional seedbeds and combines light supplementation, temperature, moisture and other seedling raising factors. It can significantly improve the emergence rate per unit area and seedling raising efficiency. It is an important way to realize modern seedling raising technology. Technical means is also one of the development directions of seedling breeding in the future. In the prior art, there are published patents "A Multi-layer Cultivation System" (Application No. 2016112203415) and "A Multi-layer Seedbed for Greenhouse Seedlings" (Application No. 2016206408076), which propose the basic structural framework of the multi-layer seedling mode, but do not propose Specific ap...
