Embodiment 1

[0045] This example provides a method for determining the optimal light intensity in a commercial closed-type leafy vegetable production system. In the following method, the optimal water, fertilizer, and carbon dioxide concentration conditions are used, and are set to be constant during the control process.

[0046] Specifically:

[0047] S1. Obtain the market sales price P of the leafy vegetables to be planted in the commercial closed leafy vegetable production system;

[0048] S2. Let the light intensity in the production system be L i ; Assuming that the number of vegetable planting days is j, and j=1,2,3...h-1,h; calculate the daily effective yield of vegetables from the planting day j=1 to the harvest day j=h according to the formula I , the effective yield Y of vegetables on the hth day Li，h That is, the effective yield Y (L i );

[0049]

[0050] In the formula I, Y Li，j Represents the light intensity L i The effective yield of vegetables on the jth day under ...

Embodiment 2

[0080] This embodiment provides a light environment control device for a commercialized closed leaf vegetable production system, its structure is as follows: image 3 As shown, it includes: an illumination sensor unit 1 , an illumination intensity optimization decision-making unit 2 , an illumination intensity control unit 3 , and an illumination intensity execution unit 4 .

[0081] The illumination sensor unit 1 consists of three illumination sensors distributed in different positions of the production system to collect the illumination intensity of the artificial light source in the system, average the illumination intensity collected by different sensors and send it to the illumination intensity control unit 3 .

[0082] The light intensity optimization decision-making unit 2 simulates the effective output of vegetables under different light intensities in combination with the vegetable output estimation model according to the market price of vegetables to be planted and th...

Abstract

The invention relates to a determination method for optimal illumination intensity and a luminous environment regulation method in a commercialized enclosed type leaf vegetable production system. The invention also provides a commercialized enclosed type leaf vegetable production system. The objective of the invention is to obtain maximum benefit of leaf vegetable planation, and the invention provides a method and a device for luminous environment regulation of a commercialized enclosed type leaf vegetable production system. Through a series of mathematical physics model calculation, reasonable illumination intensity is determined through an optimization method, to realize high-efficiency intension production of leaf vegetables. The methods and the system have excellent practical and promotional values.

Description

technical field [0001] The invention relates to the technical field of high-efficiency and clean production of vegetables, and in particular to a method for determining optimal light intensity in a commercial closed-type leafy vegetable production system, a light environment control method and a system. Background technique [0002] Leafy vegetables have a short growth cycle, high multiple cropping index, and delicious taste, and are deeply loved by consumers. Due to the high multiple cropping index often leads to outbreaks of diseases and insect pests, in order to maintain high yield, a large amount of pesticides have to be used in the vegetable planting process, which on the one hand caused the deterioration of vegetable quality, and on the other hand, pesticide residues also brought harm to the health of citizens. With the improvement of living standards, people have higher and higher requirements for the quality of leaf vegetables. [0003] The closed-type leafy vegetab...
