In the winter greenhouse planting process, due to insufficient light in the shed, not only the yield of the plants may shrink, but also the quality of the plants will also be affected. At the same time, the growth cycle of the plants will be prolonged and the planting management cost will be increased. The use of LED plant lights to increase the light in the greenhouse can effectively end the above problems.
But with LED plant lights, summer lighting LED plant lights with sunlight can well meet the needs of plant growth, but in winter, there is still a slight lack of light. When you are unwilling to increase the purchase cost of LED plant lights, let’s talk about it. The supplementary light technique of LED plant light:
1. Different types of plants should be planted in a reasonable combination. According to the characteristics of the plants, layout according to natural rules, such as: planting plants in the northern hemisphere, it is best to follow the principle of high in the north and low in the south, so that all plants can receive light evenly, and try not to show plants. Occasional shading;
2. For vine planting, in order to improve the effective utilization of light, use reflective materials when erecting the frame, such as: use some waste plastic film to wrap around the bamboo and wood support. In addition, the brackets do not need to be all upright at 90 degrees, keep the middle bracket upright, and the brackets on the north and south sides are slightly inclined, which can increase the light utilization rate by 5--10%;
3. The ceiling cleaning increases the transparency and the amount of light in the shed. Regularly clean up the "ceiling garbage", especially after it snows, to clean it up in time, otherwise it will have a great impact on the light and temperature in the shed, which will affect the photosynthesis and respiration of plants. Effect, which ultimately affects the yield and quality of plants;
4. Reflective measures can be taken around the greenhouse, which can reflect a large part of the scattered light back and be reused by plants;
5. Use LED plant lights to fill light. On the one hand, you can appropriately shorten the lighting distance. Generally, when you buy LED plant lights, you will buy them according to the installation area and the irradiated area of the LED plant lights. The actual irradiation area of the LED plant lights will be slightly larger. The theoretical irradiation area can be appropriately shortened within a reasonable range to increase plant supplement light.
