摘要： 通过半腐解秸秆覆盖旱作、地膜覆盖旱作、裸地旱作比较试验，研究了在田间覆盖条件下旱作水稻的生长发育以及产量形成特征。结果表明，在水稻生长期，降雨量为440 mm条件下，与其他旱作相比，采用半腐解秸秆覆盖，水稻生育前期植株个体生长受到一定抑制，但生育中后期有利于水稻植株的生长发育，分蘖成穗率较高，冠层叶长，叶面积大，光合功能强，每穗结实粒数多，粒重大，产量高。

Abstract: Some characteristics of rice cultivated in aerobic soil mulched with semi-decomposed straw and plastic film and without any mulch were compared under field conditions. During the period of rice growth with about 440 mm precipitation, the rice grew and developed much better at middle and later stages in the soil mulched with straw than under the other two cultivation treatments. The yield components of rice grown in soil with straw mulched, such as filled grains per panicle and 1000-grain weight, were improved significantly compared with those under the other aerobic cultivation treatments.
