With TOP130-PC plate covered greenhouse as research object，and with PO coated film greenhouse as control，and reform manual ventilation by using roll volum film device to mechanical ventilation，environmental factor(air temperature，humidity，illumination intensity from ground 1.5 meter，ground temperature in 0～20 cm，etc.)was determined in greenhouse，dew condition and crop growth condition were observed，to evaluate thermal insulation properties light transmittance of new TOP130-PC plate replace traditional PC plastic film of greenhouse.The results showed that,PC greenhouse daily air temperature increased 1.26℃ and air humidity reduced 8.31% compared with contrast greenhouse，and PC greenhouse could resist strong wind and snow，with high automation，long service life cost and wide prospect of application.
