Greenhouse make-up lamp, also known as plant make-up lamp, is a kind of lamp which uses light instead of sunlight to provide light source for the growth and development of greenhouse plants according to the natural law of plant growth and the principle that plants use sunlight for photosynthesis.
Perpetual lamp plants are perpetual lamp plants in greenhouse. Perpetual lamp is a lamp specially designed for plants. It can play a role in promoting plant growth. With the development of science and technology, the technology of plant growth lamp has also made great progress.
The perpetual lamp perpetual lamp has been used in greenhouse for 2 years. The research and application of greenhouse growth lights in greenhouse facilities showed that it can solve the problems of the impurity in the spectral components of the artificial light sources, such as the unpurity of light, the inconsistency of light intensity, and the low efficiency of light source irradiation. The application of greenhouse lamp technology in greenhouse is also a new technology. The research of the plant growth lamp in greenhouse is carried out in the greenhouse. The results show that the plant perpetual lamp is a new technology in greenhouse cultivation. The results show that it can solve the problems of the impurity in the spectral components of other artificial light sources, such as the purity of light, the inconsistency of light intensity, and the low efficiency of light source irradiation.
The light supplement lamp in the shed can significantly promote the development of spinach, radish and lettuce, improve the morphological index, and increase the growth rate and photosynthetic rate by more than 50%. It can increase the biomass accumulation of beet. The sugar and starch accumulation in the hairy root can significantly change the shape of the stems and leaves of pepper and perilla, and the photosynthetic rate of plants is significant Improve. When applied to flowers, it can increase the number of buds and flowers, improve the quality of flowers and prolong the flowering period. At present, the plant fill light lamp has become popular in the planting of flowers and vegetables.
Prospects for development
In recent years, with the improvement of agricultural productivity, the domestic greenhouse has developed rapidly. The reasons are as follows: (1) the domestic market for flowers, fruits and crops is active, and the greenhouse is used to produce anti season crops; (2) the spring seedling of rice and other fruit vegetables; (3) the high-tech plant factory with artificial control of the growth conditions, realizing the ecological agriculture of soilless cultivation and green food, etc The needs of industry development, etc.
At the same time, modern greenhouses are widely used in the world to increase production by creating conditions suitable for crop growth. The Netherlands has built a 110 million M glass greenhouse, which accounts for one quarter of the total area of the world. Its agricultural exports rank the third in the world, and it has achieved significant yield benefits. For example, the per unit yield of hot pepper in the warm room is 30 kg / m, and the per unit yield of tomato is 60-70 kg / m. The United States has built a "seedling factory" in San Paula, Los Angeles, which adopts bioengineering methods to cultivate fruit tree seedlings with single cells and realizes large-scale industrialization. At present, the high value-added agricultural products such as vegetables, fruits and flowers in developed countries are mainly supplied by greenhouse. It is an inevitable trend of modern agriculture to adopt greenhouse cultivation of high-efficiency agriculture.
