China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

Through the spectrum required for green plant 600W sodium lamp ballast, can not only promote their growth, but also to extend the flowering period, improve the quality of fruits, to ensure that the greenhouse vegetables taste, but also of-season cultivation. The rational use of the plant growth lamp is not suitable for the growth of plants under conditions of breeding and growth, and can accelerate the breeding of crops and shorten the crop growth cycle, eliminating the occurrence of pests, diseases and abnormal fruit.
The stronger the light, the more strong plant development; reduced light, reduced photosynthetic capacity. Eggplant day length and strength requirements. Seedling stage: eggplant seedlings fertility, not only by the light intensity, but also by the impact of day length. According to tests, in the 15 to 16 hour day length, strong seedling growth, flower bud early, with flower node. The seedling growth optimum temperature of 22 ° C to 30 ° C. Flowering and fruiting period: strong light. Under low light, the less dry matter produced by photosynthesis, plants accumulate substances, flowering decrease in the number of an increase in the number of falling. Temperature management, the key is the temperature difference between day and night, daytime temperatures to maintain the temperature to promote photosynthesis, night temperatures remain conducive leaves assimilates out operation. Suitable temperature difference between day and night: during the day and 22 to 25 ° C, maximum 26 to 28 ° C; night 13 to 15 ° C, not higher than 20 ° C. The result of a good temperature control has an important role to the high-yield. The daytime temperature suitable range between 20 ~ 30 ℃, 25 ℃ as the most suitable. Night optimum temperature is 18 to 20 ° C, such as the night temperature is high, does not promote the development of the most productive fruit enlargement, due to the decrease of assimilation of the material sent to the growth area, vegetative symptoms will gradually appear, thus affecting the successor flowers and fruits growth and development, leading to production cuts.
