Problems solved by technology

There are basically two ways to supplement the light above: one is to use sunlight, but it is difficult to control the intensity of light. If the light is too strong, the seedlings will be sunburned; if the light is too weak, the photosynthesis of the seedlings is not sufficient, which will affect the growth. The second is to use fluorescent lamps to supplement the light. Although the light intensity can usually be controlled, the spectrum of this light is not the most suitable for the growth of seedlings. Due to insufficient photosynthesis, the seedlings are not strong
At the same time, it will lead to a long growth period. Usually, the growth cycle of leafy vegetables is about 60 days. The time required for traditional seedling raising methods is generally 20 days or more, accounting for 1 / 3 of the entire plant growth cycle, or even more, which seriously restricts Rapid and efficient plant production

Abstract

The invention relates to the field of plant seedling culture, in particular to a plant seedling culture method, which is suitable for culturing strong seedlings during leaf vegetable plant seedling culture. At a strong plant seedling culture stage of the culture method, red LED (light-emitting diode) lamps and blue LED lamps are used for irradiating plants to culture strong seedlings in a strong seedling culture box, wherein the daytime temperature of the strong seedling culture box is kept to be 23-27DEG C, the nighttime temperature of the strong seedling culture box is kept to be 15-20DEG C and the relative humidity of the strong seedling culture box is kept to be 70-80 percent. The plant seedling culture method has the advantages that the aboveground parts of small seedlings can be enabled to be strong, the photosynthesis is promoted, the underground parts of the small seedlings are well-developed, the absorption of water and nutrient substances is promoted, the growth of the plants is facilitated, the transplanting survival rate is improved, the seedling culture period and the transplanted seedling resuming growth period are shortened, and the yield is improved.

Description

technical field [0001] The invention relates to the field of plant seedling raising, in particular to a plant seedling raising method, which is suitable for strong seedlings in leaf vegetable seedling raising. Background technique [0002] At present, with the continuous expansion of plant production area and scale, in order to reduce the risk of seedling cultivation, more and more plant production units choose to carry out unified seedling cultivation or choose reliable seedling cultivation units to purchase finished seedlings, which requires more and more Large-scale uniform cultivation of more and more seedlings. If the conditions for raising seedlings are not well grasped, it will cause great business risks to the seedling raising unit, and cause irreversible life-long impacts on all aspects of the entire growth process of the seedlings raised. [0003] Usually, seedlings are bred in high density under the conditions of natural light and artificial light, and supplement...
