This article studied the variation regularity of soil moisture and temperature and the impact on the cherry tree growth under 6 agronomic measures during an annual growth cycle ,then made a comprehensive assessment of the 6 agronomic measures ,expecting to provide experience in choosing the most suitable agronomic measure in Beijing suburbs orchard .The results showed ,the average soil temperature in the depth of 0~80 cm is :plastic mulch (D)> groundcover (B)> polyacrylamide + super-absorbent-polymers (PS)> straw with groundcover mulching (JB)> liquid film mulching (Y)> check treatment (CK)> branches mulching (Z);the soil pondage in the depth of 0~80 cm is :JB> PS> B> D> Y> Z> CK ;the agronomic measures in order of comprehensive applicability in Beijing suburbs orchard is :PS> JB> B> D> Y> Z .But considered the economic cost of agronomic measures ,groundcover(B) is more conducive to extend .
