【摘要】 采用田间试验,研究不同穴播种植方式对旱地春小麦产量及水分利用效率的影响。结果表明,在4种穴播种植方式中,全膜覆土穴播种植方式对促进小麦生长、提高小麦产量和水分利用效率的效果突出;该种植方式下小麦产量较露地穴播、全膜不覆土穴播和全膜小垄沟覆土穴播分别增加72.8%、22.6%、8.0%,小麦水分利用效率较露地穴播、全膜不覆土穴播和全膜小垄沟覆土穴播分别提高111.1%、28.1%、6.5%,干旱年份效果极为明显。可见,全膜覆土穴播栽培方式可显著提高小麦籽粒产量和水分利用效率,干旱年份效果明显。更多还原

【Abstract】 Field trials were conducted to study different bunch-planting cultivation on wheat yield and water use efficiency in the semi-arid area.The results showed that cultivation of bunch-planting under earthed film was used to growing of wheat plants and increasing dry matter accumulation,and effect of increasing yield and water use efficiency was obvious;compared with bunch-planting in open field,bunch-planting under the film,and bunch-planting in earth-filmed small-furrow,wheat yield increased by 72.8%,22.6%,and 8.0% respectively,and water use efficiency increased by 111.1%,28.1%,and 6.5% respectively,and the effect of which was particularly prominent in dry years.In conclusion,the cultivation mode of bunch-planting under earthed film can significantly increase grain yield and water use efficiency,especially in dry years.更多还原
