摘要
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5751.0~6453.0 kg/hm^(2),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·hm^(2)),较不覆膜穴播提高58.9%~82.2%。覆膜穴播糜子产量为4525.5~5040.0 kg/hm^(2),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·hm^(2)),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 5751.0~6453.0 kg/hm^(2),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·hm^(2)),which was 58.9%~82.2%higher than that of hill-planting without film mulching.The yield of Panicum miliaceum L.was 4525.5~5040.0 kg/hm^(2),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·hm^(2)),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.
