Scientific Analysis And Management On The Environment Factors In The Greenhouse Of North Of China

The time of sunshine is short and the temperature of ground is relatively low in winter in the northern area , so the effective accumulated temperature can't satisfy the requirement of growth and development of the crop at all . The greenhouse, as northern area keep main production facility of culture warm winter in our country, seems particularly important to peasants' economic income of northern area. But at present, there are many problems in the greenhouse production in the north of our country. One of the classic problems is : the ability of regulation and control is not high, the primitive and extensive way of production is seriously, the scientific degree of management is low. All of these have caused the slow growth , low production and no perfect benefit.For solving this kind of problem effectively, we are going to carry on the scientific analysis on the relevant factors which influence the growth, development and production of crops in the greenhouse , such as temperature , illumination , humidity, gas), We are trying to explore a scientific effective management method, which promote crops high yields and high-efficient in the greenhouse, plastic tunnel of the north of our country , Then find out a synthetic management mode, which will offer the theoretical foundation for the fact that the facility agriculture gets bumper crops.
