在自然降水条件下，采用化肥、有机肥、生长期覆盖、深耕等相结合的综合技术栽培春小麦可大幅度地提高其产量和水分利用效率。6年试验期间，在综合农业技术中，无论何种年型施用化肥（N和P2O5各135～150kg/hm）对增产和水分利用效率的提高，约占50％；充足有机肥的作用约占30％；生长期间行间覆盖技术的作用约占20％；深耕25cm的作用不明显。
Under the condition of natural precipitation, the cultivation of spring wheat with the combination of chemical fertilizers, organic fertilizers, growing season covering and deep plowing can greatly improve its yield and water use efficiency. During the 6-year experiment, no matter what kind of annual application of chemical fertilizers (135 ~ 150kg / h of N and P2O5) to the increase of yield and water use efficiency in integrated agricultural technology, accounting for about 50%; the role of adequate organic fertilizer accounts for about 30%. During the growth period, the effect of inter-line coverage technology accounts for about 20%. The effect of deep plowing 25cm is not obvious.
