Temperature control techniques for hydroponic flowers

The temperature conditions required for safe wintering of flowers under hydroponics conditions are consistent with the temperatures required for soil cultivation (artificial medium cultivation). Hydroponic flowers are not tolerant to cold flowers, and the optimum temperature for growth is generally 18°C-25°C. When the temperature drops below 10°C, some flowers grow stagnant and the leaf color loses luster; below 5°C, most foliage plants suffer Different degrees of injury - leaf scorch, old leaves yellow, wilt off, and even death.

In the absence of facilities and capabilities to adjust the ambient temperature, it may be desirable to choose flowers that have a wider range of temperature adaptations, such as Monstera, calla lilies, ivy, tiger-eye evergreen, and clivia. In addition, discarded foam boards can be used, cut to size according to the dimensions of the hydroponic vessels, and then spliced ​​and glued to wrap the vessels. When the room temperature is lower than 10°C, it is very effective to cover old newspapers and plastic films on hydroponic flowers, or to increase the water temperature to 18°C ​​or 25°C.

When the room temperature is below 10°C in winter, most hydroponic flowers are dormant or semi-dormant under harsh climatic conditions. At this point should stop the application of flower hydroponic nutrient solution, only with tap water, and change the water on time (when changing the water appropriate to incorporate some warm water, so that the water temperature is maintained at about 18 ~ 25 °C), clean the plant's roots, keep utensils clean. Usually 10 to 15 days to replace a new water, if the water is pure and clean, the plants grow strong, no rot, 15 to 20 days and even 30 days to replace once will not affect its growth. For those water-cultivated flowers that are still growing slowly, such as kaffir lily, calla lily, etc., a nutrient solution can be applied once every 10-15 days to promote its healthy growth.

Meat more than we raise chicken, Turkey, stout, fleshy structure and nutrition ratio more reasonable, in the soil chicken contains rich protein, trace elements and a variety of nutrients, fat content is low, have important value for our human body health, is our Chinese people prefer meat products, belong to high protein meat.Native contains rich amino acids, amino acids for human body has a very important role, he is to make up our human body protein and related to the life activities of the most basic material, is in the biological constitute the basic unit of protein molecules in the body, is our basic material life, there is a close relationship to human life activities. It is an indispensable nutrient in our body. These nutrients in Turkey are very important for the growth and development of our bodies.
