中文摘要	为探究西北半干旱雨养条件下适合冬小麦种植的覆盖保墒技术,以小麦品种陇中2号为试验材料,设置2种秸秆带状覆盖方式(秸秆带状4行、秸秆带状5行) 、地膜全地面覆盖和无覆盖种植4个处理,以无覆盖种植为对照(CK) ,研究冬小麦不同覆盖方式对土壤水分及产量的影响。结果表明,2种秸秆带状覆盖较CK显著增产28.1% ~ 35.4%,单位面积穗数显著提高35.1% ~ 50.8%,表明增加穗数是秸秆带状覆盖增产的主要原因。与CK相比,秸秆带状覆盖具有增墒和降墒的双重效应,在分时期、分土层共72个测定点次中,2种秸秆带状覆盖增墒点次比例分别为61.1%、58.3%,相应降墒点次比例分别为38.9%、41.7%;秸秆带状覆盖的降墒效应在乳熟期表现最为明显,其降墒点次比例平均为81.2%,在其他时期则普遍表现为增墒效应,增墒点次比例平均为64.9%; 2种秸秆带状覆盖在各土层的增墒点次均大于或等于50%,且在40 cm以下土层的增墒点次在60%以上,增墒效应更为突出。综上,秸秆带状覆盖方式保墒、增产增效显著,是西北旱地小麦可大面积推广种植的新技术。本研究为半干旱雨养区冬小麦夏玉米推广应用提供了理论依据。
英文摘要	To explore the planting technology of soil water moisture suitable and preservation for winter wheat (Longzhong-2) planting under the condition of semi-arid rain in Northwest China. Tests included two kinds of straw strip mulching,plastic film mulching and non-covered planting a total of four treatment,studied the differences of straw strip mulching on winter wheat yield and soil water dynamics. The results showed that compared with CK,straw strip mulching on the yield of winter wheat average significantly increased by 28.1% ~ 35.4%. Grain yields were increased caused by the rising of spikes per unit area,and average spikes per unit area of straw strip mulching was significantly increased by 35.1% ~ 50.8%. The spikes per unit area showed higher positive correlation with the high grain yield per unit area. Compared with CK,the straw strip mulching on the soil had double effects of increase and reduce the moisture. In all 72 measurement points according to sub-period and sub-soil two kinds of straw strip mulching soil moisture contented increased points accounted for 61.1% and 58.3% of the total measuring point during the whole growth period and decreased content points accounted by 38.9% and 41.7%,respectively. The effects of straw strip mulching on the soil moisture decrease prominently in the milking stages,the average percentage of soil moisture content decreased points 81.2% respectively,in the other seven periods generally showed increased moisture effect,the average of soil moisture content increased points accounted for 64.9%. The increase points of straw strip mulching in all soil layers were greater than or equal to 50% and below 40 cm sub-soil substantially more than 60%,and showed more prominent effect of increasing moisture. In summary,both two different production methods of straw strip mulching had good effects of increased yield and increased soil moisture,accorded with the demand of high yield,high efficiency, healthy and sustainable development of wheat in ecological fragile area,which was a new technology worth popularizing in a large area of the northwest semi-arid area. This study provided a theoretical basis for the popularization and application of winter wheat and summer maize in semi-arid rain areas.
