It is impatient to develop high quality and beneficial agriculture after entering WTO.When we had achieved effect in covering horticulture today.We should pay attention to the problems and solving methods of limiting continuous development in covering horticulture.When we analyzed the state of covering horticulture through the world recently.We have given many problems in which the modern greenhouse had low level.It is short of the standard in designing and of having necessary mechanics.Another problems was that the soil of protecting areas was short of rainy.The physics state was more and more worse.We had lower level in cultivated technology and scale produce.The product was polluted seriously.The energy-saving solar greenhouse kept warm badly in winter.So it is important to develop all kinds of expert system. We have given many solving methods in continuous development of covering horticulture.The optimal design of structure and new covering materials of having high solar permeability and heat preservation was introduced.We must make use of solar and all kinds of energy-saving greenhouse in three parts of planting and animal husbandry and marsh gas.We will realize mechanization and scope produce.The product will not be polluted.We will rely on science progress and accomplish the system of service technology and study a set of expert system of covering horticulture.$$$$
