沙棘(Hippohae rhamnoides)是优良的水土保持林、薪炭林树种。近年在我国“三北”地区已开始对沙棘果实、种子的开发利用,并建立了工业化的沙棘园。据知有关沙棘的栽培技术资料较多,对其生理特性研究较少,本文对沙棘的水分生理特性进行了初步研究,试图为沙棘的栽培技术提供理论依据。1 试验地概况材料和方法试验地设在沈阳农业大学植物园内。该地年平均降水量675.2mm,年平均气温8.2℃,土壤是棕色森林土。试材:5年生沙棘叶片,10年生剌槐、白榆叶片。方法:蒸腾强度用离体快速称重法测得,
Hippohae rhamnoides is an excellent soil and water conservation forest, firewood tree species. In recent years, the development and utilization of seabuckthorn fruits and seeds have started in the “Three Norths” of China and an industrialized sea buckthorn garden has been established. It is known that there are more information about the cultivation techniques of seabuckthorn and less research on its physiological characteristics. In this paper, the hydroponic physiological characteristics of seabuckthorn were studied in order to provide a theoretical basis for the cultivation of seabuckthorn. An experimental site Overview Materials and methods Experimental site located in Shenyang Agricultural University Botanical Garden. The average annual rainfall of 675.2mm, the annual average temperature of 8.2 ℃, the soil is brown forest soil. Materials: 5-year-old sea buckthorn leaves, 10-year-old acacia locust, Ulmus leaves. Methods: Transpiration rate was measured by rapid in vitro weighing method.
