Greenhouse crops to grow for the environment
Greenhouse cultivation of crops to grow for the environment no more than light, temperature, root temperature, humidity, carbon dioxide, its impact on the crop's described as follows:
1. Light: Greenhouse's daily light, can promote the growth of tomatoes, In general, every 1% increase of the light, the production increased by 1%.
2. Temperature: Greenhouse affect the function of the root, low temperature increase  the resistance of moisture movement and the absorption of the root ,  As root temperature also affect nutrient absorption, especially N and P.  Depending on the crop varieties and growing season varies, the lowest root temperature have different demand, such as cucumber and bell pepper takes about 20 ℃, while lettuce is only 15 ℃.
3. Humidity: Humidity is too high or too low affect plant growth. Humidity is too low, the evapotranspiration rate is high, the plant smaller leaves and shorter internodes, caused by Photosynthesis becomes less, thus reducing yield. On the contrary, if the humidity is high, because of the smaller evapotranspiration ,  root has less transportation of nutrients, easy to form a plant deficiency, resulting in reduced root. According to Otterloo Report: In summer, the average daily water demand of crops, is six liters per square meter.
4. Carbon dioxide:  The general atmosphere carbon dioxide content is 340ppm, in the closed greenhouse, since part of the carbon dioxide for photosynthesis plant consumed, so the carbon dioxide concentration may be reduced to 100ppm, in order to avoid this situation, typically carbon dioxide added during the day, the concentration was maintained at 700 to 1000ppm, depending on the greenhouse roof opened and the wind speed. In winter conditions, when the carbon dioxide concentration of 600 to 700ppm, vegetative growth period may be shortened by 10%. Therefore, it can improve the quality of young plants, increased plant dry weight and thick leaves, so plants less susceptible to the infection of any harm, so for the nutrition of young plants, in low light situations, the maximum recommended amount of carbon dioxide to 700ppm.
5. Biological Control Systems: Environment-conscious cultivation (ECC), the so-called ECC prevention can reduce the use of crop protection agents reach the minimum, and as far as possible to biological methods of pest control.

Inverter Micro-mist Humidifier system which can be in the greenhouse facilities, irrigation, fertilization, cooling, humidification and fully automated pesticide spraying and other work.
