1·Based on experiments of planting by stages, month average temperature and month rainfall depth showed very significant effects on damaging rates of termite on young Eucalyptus stand.
分期造林试验结果表明,月平均气温、月降雨量对桉树幼林白蚁为害率的影响极显著。
2·The relations between rainfalls, contents of soil water before rainfall, time of infiltration and depth of infiltration were described.
阐述了降雨量、前期土壤水分含量和下渗历时与水分下渗深度的关系。
3·These were tree age, stand density, resin tapping, rainfall, temperature, clay soil, stone soil, soil depth, water logging, and other diseases and insect pests.
它们是树龄、林分密度、割脂、降雨量、温度、粘性土、石砾土、土层瘠薄、积水、病虫危害。
4·The results shows, the relationship between individual rainfall runoff depth and it's sediment yield is very close.
结果表明,次降雨径流深与其对应所产生的侵蚀量关系非常密切;
5·The infiltration rate is intensively affected by rainfall intensity, and there exists a linear relation between the depth of infiltration and precipitation and rainfall intensity.
入渗深度与降雨量和降雨强度之间存在线性关系,土壤渗透能力随土壤剖面初始含水量的增加而减小,土壤稳定入渗速率的时间趋于缩短。
6·The influence caused irrigation (rainfall) is to each layer soil matric potential reduces with depth of increment.
灌水(降雨)对各层土壤基质势的影响随深度的增加而减小。
7·Rill width and depth become bigger with rainfall intensity, erosion amount promptly enhances after rill appears, accounts for 91%.
细沟的宽度和深度随雨强的增大而增大,产生细沟后侵蚀量将迅速增大,最大占总侵蚀量的91%。
