The results indicated that:(1) plant height and tillering number decreased, and root length, root surface area, root volume and rootlet number increased under drought stress; straw mulched on surface soil and pig manure mixed in soil could improve the growth and morphological property of rice root, while straw mixed in soil and pig manure mulching had no significant effects;(2) the contents of chlorophylls and the activities of SOD, POD and CAT decreased significantly under drought stress, and straw mulching on surface soil and pig manure mixed in soil could restrain these decreases.

结果表明：①干旱胁迫下水稻株高降低、分蘖数减少，根系则表现出主根伸长、支根增多、根表面积和根体积增加；秸秆表施和猪粪混施可明显改善水稻的生长和根系形态，而秸秆混施和猪粪表施的改善作用不显著；②干旱胁迫下叶片叶绿素含量显著降低，超氧化物歧化酶、过氧化物酶及过氧化氢酶活性均显著下降，秸秆表施和猪粪混施能够在一定程度上抑制这种下降幅度。

Under the plastic-mulched ridge and furrow cultivation, the average soil water content of furrow (12.7%) was significantly higher than that of ridge (9.1%) at the soil depths of 20-100 cm. The locally compacted ridge served as a water flow barrier and a rainfall collection area under locally compacted ridge and furrow cultivation, and the water content of furrow was significantly higher than that of ridge in the same soil depths, which was similar to the characteristic of soil water distribution under plastic-mulched ridge and furrow cultivation. No significant differences were found in soil water content of furrow between locally compacted ridge and furrow cultivation and plastic-mulched ridge and furrow cultivation, with the same efficiency of water collection.
