据前人研究结果表明,土壤水分对植物的有效性(Доступностъ)与土壤水分的运动性(Подвижность)关系甚密.但某些作者在研究土壤的雕萎湿度时亦早已发现,士壤雕萎湿度的大小也决定于蒸腾条件及植物的年龄.由此产生如下的问题,即在田间持水量(НВ)与土壤稳定湿度(相当于Абрамова所称的毛管联系断裂湿度)之间的湿度范围内,土壤水分的有效性是否亦受蒸腾条件(主耍是气候条件)和植物年龄的影响?因为按某些作者的意见,在这个土壤湿度范围内,土壤水分的有效经主要决定于水分的运动性,甚至水分具有同样的有效性.
According to the results of previous studies, the effectiveness of soil moisture on plants (Доступностъ) is closely related to the soil moisture movement (Подвижность), but some authors have also found that soil erosion and wilt The size of the humidity is also dependent on the transpiration conditions and the age of the plant, resulting in the problem that the moisture content between the field (НВ) and the soil stable humidity (corresponding to the capillary contact breaking humidity referred to by Абрамова) Is soil water availability also affected by transpiration (mainly climatic conditions) and plant age? Because, according to some authors, the effective soil moisture in this soil moisture range is largely determined by the movement of moisture Sex, and even water have the same validity.
