中文摘要：

为改善黑土旱作区作物的水分有效性，探索地膜覆盖不同播种模式在该地区的适用性，于2011年在哈尔滨东北农业大学节水灌溉实验基地进行试验，设置覆膜条件下垄台种植与垄沟种植2种栽培模式。以传统垄作为对照，研究地膜覆盖条件下2种种植模式对夏玉米田土壤水分、产量及土壤水分利用效率的影响。结果表明，覆膜条件下垄台种植和垄沟种植处理均能显著改善该地区玉米出苗期一拔节期土壤水分，形成较好土壤墒情，为玉米增产提供有力保障。其中垄台种植优于垄沟种植，增产效果明显，分别较对照增产15．05％和11．75％，平均水分利用效率分别提高16．33％和14．66％。因此，地膜覆盖条件下垄台种植模式在改善土壤水分效用的同时能显著增产增收，是东北黑土旱作区玉米的高效栽培模式。

英文摘要：

In order to increase water availability for crops and explore the applicability of plastic film mulching with different seeding methods in dry farming of black soil regions of Northeast China which is rain-fed agriculture, a field experiment was conducted in 2011 at Water-saving Irrigation Experimental Station of Northeast Agricultural University in Harbin of China to determine the effect of different ridge and furrow with mulching cultivation patterns on soil water, yield and the average water use efficiency of maize. The ridges were covered with common plastic film in all treatments, while different seeding methods were seeding in ridge and furrow respectively. The conventional tillage without mulch was used as a means of control. The results obtained in an experiment show that, at the seedling stage and elongation stage of maize, both methods can improve the soil moisture and make a better soil moisture conditions to provide strong protection of the yield of maize. Compared with the control, the maize yield of seeding in ridges and fur-rows with common plastic film significantly increases by 15.05 % and 11.75 %, and the average water use efficiency increase by 16. 33 % and 14.66 %, respectively. It is concluded that when the ridges are covered with common plastic film and seeded in ridge, not only the soil water and temperature conditions are improved, but also the maize yield and net income increases. Therefore, these treatment is considered as efficient for maize production in dry farming of black soil region of Northeast China.
