以晋黍7号为材料，研究了旱地不同覆膜方式对糜子各生育期植株绿叶面积、叶绿素相对含量（SPAD ）、光合特性及产量的影响。试验结果表明，与平膜穴播和露地条播相比，分蘖期至成熟期，膜侧穴播处理的糜子平均旗叶SPAD分别提高3．8％、10．2％；单株绿叶面积分别提高17．9％、59．1％；拔节期至成熟期，膜侧穴播处理的糜子平均旗叶净光合速率较平膜穴播和露地条播分别增加3．8％、28．7％，旗叶蒸腾速率分别增加7．5％、23．4％，叶片瞬时水分利用效率（LWUE ）下降幅度较平膜穴播和露地条播分别低16％、25％。在不同的覆膜方式中，膜侧穴播处理的糜子产量最高，较平膜穴播和露地条播分别增加7．6％、51．2％。因此，膜侧穴播有利于糜子光合和产量的提高。

The variety of Jinshu 7 was used as material to study the effect of film mulching modes on leaf area per plant ,relative chlorophyll content (SPAD ) ,photosynthesis characteristic and yield of broomcorn millet in arid land .The results showed that compared with flat film dibble and traditional planting ,average flag SPAD of film side dibble in-creased by 3 .8% and 10 .2% , and leaf area per plant increased by 17 .9% and 59 .1% from tillering to maturing stages ,respectively .The flag leaf photosynthetic rate and transpiration rate under film side dibble were higher than flat film dibble (3 .8% and 28 .7% ) and traditional planting (7 .5% and 23 .4% ) from jointing to maturing stages .But the decline of leaf water use efficiency (LWUE) under film side dibble were 16% and 25% less than flat film dibble and traditional planting ,respectively .By contrast ,flat film dibble and traditional planting ,grain yield under film side dibble increased by 7 .6% and 51 .2% ,respectively .Therefore ,the pattern of film side dibble is favorable for improving pho-tosynthesis characteristic and yield of broomcorn millet in arid land .
