摘要
Abstract
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.关键词
