以晋黍7号为材料，研究旱地不同覆膜方式对糜子生育后期干物质积累与转运的影响。试验结果表明，整个籽粒灌浆期，与露地条播相比，膜侧穴播、平膜穴播地上干物质的积累量分别增加55.56%、27.88%，籽粒干重分别提高9.25%、24.90%。覆膜能够促进花后营养器官干物质向籽粒中转运，茎干物质对籽粒的贡献率高于叶、鞘，其贡献率高达55.31%～56.08%。覆膜处理对糜子单株粒数、千粒重有明显的促进作用；膜侧穴播、平膜穴播分别比露地条播增产40.52%、51.2%，说明膜侧穴播对糜子干物质积累与转运的促进效果优于平膜穴播，有利于糜子产量的提高。
以晉黍7號為材料，研究旱地不同覆膜方式對糜子生育後期榦物質積纍與轉運的影響。試驗結果錶明，整箇籽粒灌漿期，與露地條播相比，膜側穴播、平膜穴播地上榦物質的積纍量分彆增加55.56%、27.88%，籽粒榦重分彆提高9.25%、24.90%。覆膜能夠促進花後營養器官榦物質嚮籽粒中轉運，莖榦物質對籽粒的貢獻率高于葉、鞘，其貢獻率高達55.31%～56.08%。覆膜處理對糜子單株粒數、韆粒重有明顯的促進作用；膜側穴播、平膜穴播分彆比露地條播增產40.52%、51.2%，說明膜側穴播對糜子榦物質積纍與轉運的促進效果優于平膜穴播，有利于糜子產量的提高。

The variety of Jinshu 7 was used as material to study the effects of film mulching modes on dry matter accumulation and transportation characteristics of broomcorn millet at later growing stage in arid land. The results showed that it compared with traditional planting,and the above-ground dry matter accumulation of film side dibble and flat film dibble increased by 55.56%, 27.88%,and seed dry matter increased by 9.25%,24.90% in the whole grain filling periods. Film mulching can contributed to the transportation of dry matter of vegetative organs to grains. The contribution to grain yield of stem was bigger than those of leaf and sheath,which was as high as 55.31%-56.08%. Film mulching had the obvious role in promoting grain number per plant and 1000-grain weight. Compared with traditional planting,the yield of film side dibble and flat film dibble increased by 40.52%and 51.2%, respectively,Which indicated that the effect of film side dibble to dry matter accumulation and transportation was better than film dibbling so as to increas grain yield in broomcorn millet.
