在宁南干旱区采用田区定位试验方法，研究了不同覆膜穴播模式谷子和糜子生长期主要农艺性状、耗水特征与产量的关系。结果表明，覆膜穴播谷子产量为5 751.0～6 453.0 kg/hm2，增产效果依次为渗水微膜、普通微膜、垄上覆膜+沟内穴播、降解微膜，较不覆膜穴播增产48.4%～66.5%，水分利用效率(WUE)为17.40～19.95 kg/(mm·hm2)，较不覆膜穴播提高58.9%～82.2%。覆膜穴播糜子产量为4 525.5～5 040.0 kg/hm2，较不覆膜穴播增产53.9～71.3%；水分利用效率(WUE)为14.25～16.95 kg/(mm·hm2)，较不覆膜穴播提高31.9～56.9%。在干旱半干旱区干旱胁迫环境下，渗水微膜穴播、垄上覆膜+沟内穴播是实现谷子和糜子种植的最佳方式。

The relationship between main agronomic characters， water consumption characteristics and yield of foxtail millet and Panicum miliaceum L. under different film mulching and hill-seeding modes was studied by field location experiment in the Arid areas of Southern Ningxia. The results showed that the effect of increasing yield was in the order of water-permeable plastic-film mulch，traditional plastic-film mulch， mulching of ridge with plastic film + hole-planting in furrow and degradable plastic-film mulch， the grain yield of foxtail millet of mulching hole-planting was 5 751.0 ~ 6 453.0 kg/hm2， which was 48.4%~66.5% higher than that of no covered hole-planting (CK)， and the water use efficiency (WUE) was 17.40~19.95 kg/ (mm·hm2)， which was 58.9%~ 82.2% higher than that of hill-planting without film mulching. The yield of Panicum miliaceum L. was 4 525.5~5 040.0 kg/hm2， which was 53.9%~71.3% higher than that of no covered hole-planting， water use efficiency (WUE) was 14.25~16.95 kg/(mm·hm2)， which was 31.9%~56.9% higher than that no covered hole-planting. Under drought stress in arid and semi-arid region， the best planting method of high yield and high efficiency was to adopt permeable micro-film hill-planting and ridge with plastic film + hole-planting in furrow.
