摘要


本文的研究表明,生产率随着结构的改进而增加。这解释为,在直径为0.25mm、防水骨料为14%的土壤中,谷物产量为22.2美分/公顷,而防水骨料为8%。在土壤中,这一数字降至18.4美分/公顷(3.8美分/公顷)。众所周知,紫花苜蓿在改善土壤的水物理特性及其农业化学成分方面起着关键作用。研究表明,三叶草的抗水团聚体含量明显高于棉田。从以下比较中可以清楚地看出这一点。因此,棉花田0-10cm土壤中抗水聚集体的数量为4.0-18.5;0.5cm为6.5-11.2,20~30cm为4.5-18.2,而三叶草作物中抗水聚集体的数量为35.0;增加到24.7和27.0。此外,还揭示了苜蓿栽培过程中有机物和矿物质的积累。他们通过对一年和两年的土壤样本的分析证明了这一点。结果表明,一年生苜蓿地表层土壤腐殖质含量为1.66%,总氮含量为0.112%;两年生苜蓿地表层土壤腐殖质含量为1.70%,总氮含量为0.150%。应当指出,灌溉耕地灌溉侵蚀的发展依赖于该地区的表面被大面积覆盖的事实。观察结果清楚地表明了这一点。结果表明,相对弱雨(0.4 mm / min)和强雨(1.4 mm / min)均可防止三叶草土壤进一步被冲刷。大雨条件下,紫花苜蓿下沟深14.4 mm, 1.4 mm / min下沟深31 mm,棉花行间沟深50.9和64.2 mm, 6 mm行间沟深78.6和113 mm
