不同穴播种植方式对旱地春小麦产量及其水分利用效率的影响

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。

Effects of Different Bunch planting Cultivation on Spring Wheat Yield and Water Use Efficiency in the Semi arid Area

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.
