在许多环境中,对作物生产力的最大损害是可用的水。生物量的积累与流经植物的水分成正比,即蒸腾作用。作物生物量积累所需的水分是由土壤水库通过根系提供的。本研究的目的是对花生(Arachim lowgaea L.)根在土壤剖面中随深度和横向扩展随时间的增长。通过土壤去核技术,我们测定了两个弗吉尼亚州的花生型花生品种在田间条件下对灌溉处理的响应,随着时间的推移,根系的生长情况。土壤剖面中的根长密度(RLD)和根重密度(RWD)在不同品种或不同灌溉处理之间没有显著差异[]
The largest detriment to crop productivity in many environments is available water. Biomass accumulation is proportional to water moving through the plant, i.e., transpiration. The supply of water for crop biomass accumulation is provided from the soil reservoir by the root system. Our objective was to quantify peanut (Arachis hypogaea L.) root growth over time by depth and lateral spread in the soil profile. By soil coring techniques, we determined the growth of roots, in response to irrigation treatments imposed under field conditions, of two virginia-, runner-type peanut cultivars over time. Root length density (RLD) and root weight density (RWD) in the soil profile were not significantly different between cultivars or among irrigation treatments []
