The effect of chemical mulch and drought and wetness change on maize growth and water use efficiency
, 2003 采用干旱防雨棚下盆栽的方法,研究不同土壤含水量下土壤表面化学覆盖对玉米抗旱成苗及水分利用效率(WUE)的影响。结果表明,利用保水剂和土壤改良剂PAM进行土壤表面覆盖能够提高玉米出苗率,有效降低土表蒸发,同时土壤干湿变化对玉米的生长更为有利 ...

Effect of straw-incorporation on soil infiltration characteristics and soil water holding capacity
, 2010 通过入渗试验及对土壤水分特征曲线的测定,对比研究了秸秆在经过粉碎、氨化及与无机土壤改良剂混合3种措施处理后加入土壤中对土壤入渗特性及持水特征的影响。结果显示:长秸秆处理加入土壤后显著降低土壤入渗能力;粉碎氨化后的秸秆较对照处理及粉碎秸秆处理能显著增加土壤稳定入渗率、土壤累积入渗量,同时在经过30d培养后土壤体积质量较对照低7.13%;无机土壤改良剂(氢氧化铁)能显著提高土壤稳定入渗率和累积入渗量,但在减小土壤体积质量、增加土壤孔隙度作用方面不如氨化秸秆处理显著 ...
