Soil compaction may limit horizontal root extension. 土壤的紧密度能限制水平根的扩展。
By limiting the horizontal distribution extent of plant root systems, the limited-areas methods can decrease spatial heterogeneity of soil water content and improve the accuracy of determination of soil water content. 有限面积法通过限制植物根系水平分布的范围,降低了根系分布区土壤含水量的空间异质性,提高了土壤含水量测定结果的准确性。
In error analyses for horizontal displacement measurement data, the observed errors are calculated with error ellipse instead of point root-mean-square errors, so as to judge whether they are just slope displacement or the measuring errors. 在对水平位移观测资料的误差分析中,用误差椭圆替代点位中误差来计算观测的误差量,以便确定是边坡位移还是测量误差。
The horizontal distribution of roots took the main root as the centre and the amount of roots reduced with the distance extension. 水平分布是以主根为中心随距离加大根重减少,随生育时期的推移根重分布比例逐渐外移。
For horizontal distribution, root biomass increases in the direction opposite to hill center with the increase of soil depth. 根系横向分布随土壤深度增加,趋向离开植株中心分布。
At jointing stage, the vertical and horizontal distribution of corn root cultivated in light loam was the most extensive, followed by loam and light clay. 拔节期,玉米根系的垂直和水平分布在轻壤土中范围最广,轻粘土中最小。
Analysis for the root causes of horizontal stripes mura involved in paper, based on optical refraction, reflection and diffraction theory, to research the root cause from a theoretical aspect. 对本文涉及的横条纹不良产生的原因进行分析,根据光学的线折射,反射以及衍射的理论,从理论上对横条纹不良的产生做研究。
The maximum depth of vertical distribution was more than 1.4 m, and the maximum density presented at 40-60 cm. The horizontal root distribution was covering almost the whole ridge and furrow range, and concentrated in the furrow and 1.8 m toward ridge direction. 其最大垂直分布深度可超过1.4m,根系最大密度在40-60cm附近,其水平分布范围几乎覆盖整个沟垄范围,集中在沟道及垄上沿蔓方向1.8m范围内。
Through horizontal expansion study, we defined the underlying causes of ecological problems: whether it is "anthropocentric"," Subject and Object "way of thinking, or science and technology, consumption, can not become the real material root for ecological problems. 通过横向拓展研究,可以发现:无论是人类中心主义、主客二分的思维方式,还是科学技术、消费方式,都无法成为生态问题的深层物质根源。
The results above suggest that root horizontal curvature resulted from exogenous H2O2 rather than from excessive accumulation of H2O2 in root cells. 这表明,初生根的水平弯曲是由外源H202的作用引起而不是根细胞内产生过多H202引起。
