Ten clones of dark-leaved willows ( Salix myrsinifolia Salisb.) were grown for two years on two different sites, Luikonlahti and Punkaharju, using various combinations of soil cultivation, fertilization and mulch treatments, with the objective of comparing the effect of different cultivation methods on the growth and total salicylate yield. In cultivated soil, the total salicylate yield ranged from 20 to 220 kg/ha, depending on the clone and cultivation method. The use of black polythene mulch and the addition of mineral fertilizer reduced the total salicylate concentrations of several clones. On the other hand, polythene mulch noticeably increased the hectare yield of total salicylates by promoting biomass accumulation.
种植了十个黑叶柳树（柳叶柳）克隆品种，在卢孔拉赫蒂和蓬卡哈茹这两个不同地点种植了两年，采用了土壤耕作、施肥和覆盖处理的各种组合，目的是比较不同种植方法对生长和总水杨酸盐产量的影响。在耕作土壤中，总水杨酸盐产量在20至220千克/公顷之间，这取决于克隆品种和种植方法。使用黑色聚乙烯覆盖物和添加矿物肥料降低了几个克隆品种的总水杨酸盐浓度。另一方面，聚乙烯覆盖物通过促进生物量积累显著提高了总水杨酸盐的公顷产量。
