Abstract: The paper aims to study water requirement for the growth and development of blueberry and the effect of plastic film mulching on blueberry under different water conditions. With blueberry‘Blomidon’as the test material, the author investigated the effect of film mulching on the growth of blueberry under watercontrolled irrigation for 3 consecutive years in the Greater Khingan Range area of China. The results showed that the moisture condition significantly affect the blueberry plant growth. Without plastic mulch and under 3 gradients of artificial water control in different years, the blueberry plant height, north-south and east-west crown diameter and diameter of branches and the branches increased in various degrees compared with that of CK. Soil relative water content maintained at 45%- 60% was more suitable for the growth of blueberry. In addition, the non irrigation treatment (CK) and the plastic film mulching treatment with relative soil water content maintained at 30%-45% could obviously promote the growth of blueberry plants.
