Light-controlled tomato seedling method and illumination equipment

Abstract

The invention provides a light-controlled tomato seedling method and illumination equipment. The seedling method is capable of of stimulating the increase of plant chlorophyll, enhancing the photosynthesis of seedlings, or enhancing the root growth of the seedlings through the change of light quality at different seedling stages. Meanwhile, the crops are subjected to seedling hardening in a treatment mode of enhancing the illumination intensity and (or) increasing the illumination time, so that the seedlings are hardened and the disease resistance is enhanced.

Description

【Technical field】 [0001] The invention relates to the technical field of agricultural plant cultivation, in particular to a light-regulated tomato seedling cultivation method and illumination equipment. 【Background technique】 [0002] With the continuous adjustment of the agricultural industry structure and the rapid development of the facility vegetable industry, new changes are also taking place in vegetable planting methods and vegetable seedling raising techniques. As the saying goes, "50% of the harvest is good for seedlings". As an important part of facility vegetable cultivation, vegetable industrial seedling cultivation plays an increasingly prominent role in vegetable cultivation; cultivating and applying appropriate-age seedlings has become an important factor to ensure early maturity, high yield, and high yield of facility vegetables. Great quality for important measures. The production of vegetable seedlings is often carried out in the following ways, such as: 1...

AI Technical Summary

Problems solved by technology

There are major problems, one is that the light quality cannot be flexibly adjusted at the seedling stage, and the light quality cannot be adjusted according to the growth of the seedlings to promote the growth of plant seedlings; the other is that the high-pressure sodium lamp emits a lot of heat during the lighting process and cannot be irradiated at close range Plant seedlings, otherwise it is easy to burn the plant seedlings; the third is the lighting equipment made of red LEDs and blue LEDs, the cost is high, the light quality is not easy to be evenly distributed, and it is easy to form light spots

If the red light is irradiated once by using the LED, it will cause the seedlings to suffer from elongated growth, resulting in the occurrence of leaf wilting

In addition, the alternating irradiation of red and blue light promoted favorable growth of planted plants, but tended to cause plant shoots to suffer from elongated growth
