Different types and growth periods of seedlings have different requirements for light. Different LED plant lights are required to shorten the growth time of seedlings and ensure the quality of seedlings. Only then can they have strong market competitiveness and obtain more information. More profit.
(1) Planting dormancy
Some seeds will be dormant, and they need to be "awakened" to sprout and grow. Using LED plant lights to emit a reasonable spectrum is one of the ways to wake up plants from dormancy.
(2) Environmental control and facility control
Natural weather is accidental and extremely destructive. Wind, rain, thunder, electricity, temperature, humidity, air and other factors are difficult to control. Therefore, early seedlings are usually raised on a piece of land, mixed with nutrient soil, and plastic film is used. Hollow covering can avoid some natural disasters to a certain extent, but the light is not easy to control. When the weather is clear, it can be watered, shaded, and ventilated. In the case of continuous rainy days, these aspects are difficult to control. The best method is to use indoor seedlings to make the environment controllable, and LED plant growth lights can be used to supplement the light.
(3) Accept LED plant lighting
Observe the germination degree of seeds every morning and afternoon, master the time to fill up the seedlings. When the radicle does not exceed 0.5cm and the hypocotyl has not leaked out of the soil surface, stop the germination and use LED plant lights to provide proper light. Prevent the jade noodles from being elongated, and improve the overall quality.
(4) Management during the nursery period
The environment and management techniques for the growth of plug seedlings are important factors that affect the quality of the plug seedlings; after the seedlings are grown, a good root system is required to increase the survival rate of transplantation. Therefore, whether the seedlings are tough or not can maintain the prosperity of the root system. The growth of the stems and leaves above the ground is easy to cause excessive growth, which has an adverse effect on the field of colonization. Using the blue light of LED plant growth lights can effectively promote the healthy growth of rhizomes.
(5) Environmental control during the nursery period
It is very convenient to grow seedlings indoors. LED plant lights can evenly control reasonable light, and can reasonably control indoor temperature and humidity according to the needs of different plant seedlings. However, if it is planted outdoors and natural conditions are good, you should also pay attention to the temperature and light control in the shed, and seal the shed at night to ensure that the temperature in the shed will not be too low and frostbite seedlings. It is hot at noon, and more conditions can make the shed. Inside ventilate, half lift the plastic film to prevent the seedlings from being burnt.
