摘要

摘要柳树(Salix viminalis spp.)碎屑沿着河岸种植在侵蚀性和边缘农田上。由木质生物质制成的木屑可以改善马铃薯系统中有机质含量低的轻质纹理土壤的性能。柳树芯片在0、20、40和60mgha时使用?1(新鲜重量)作为土壤修正案。12个月后评估土壤健康参数,18个月后整个土壤、颗粒物和矿物相关有机物组分中的C和N含量紧随其后。柳树芯片的应用增加了整个土壤中的土壤聚集、呼吸、C和N含量,以及植物可用性K。白柳条(Salix viminalis spp.)沿河岸和易受侵蚀或无利可图的农田种植。从木质生物质中提取的木屑可以改善低有机质质地的土壤特性,如马铃薯作物。作者采用了相当于每公顷0、20、40或60毫克(鲜重)柳条屑的修正案。12个月后,他们评估了土壤活力,18个月后评估了完整土壤的C和N含量以及与颗粒物和矿物质相关的有机质分数。柳条片改善土壤聚集和呼吸,改善整个土壤中的C和N浓度,以及植物吸收的K。[由编辑翻译]

Shrub willow chips incorporated after potato harvest enhance soil properties in Prince Edward Island, Canada
Abstract Willow (Salix viminalis spp.) shrubs are being planted along riverbanks, on erodible and marginal farmland. Wood chips made from the woody biomass could improve the properties of light-textured soils with low organic matter content in potato-based systems. Willow chips were applied at 0, 20, 40, and 60mgha?1 (fresh weight) as a soil amendment. Soil health parameters were evaluated after 12months, followed by C and N contents in whole soil, particulate, and mineral-associated organic matter fractions after 18months. Willow chip application increased soil aggregation, respiration, C and N contents in whole soil, and plant-available K. On plante l’osier blanc (Salix viminalis spp.) le long des berges ainsi que sur les terres agricoles sujettes à l’érosion ou peu rentables. Des copeaux de bois tirés de la biomasse ligneuse pourraient améliorer les propriétés des sols à texture légère pauvres en matière organique, comme ceux servant à la culture de la pomme de terre. Les auteurs ont appliqué un amendement correspondant à 0, 20, 40 ou 60 Mg (poids frais) de copeaux d’osier par hectare. Douze mois plus tard, ils ont évalué la vitalité du sol puis, au bout de dix-huit mois, la teneur en C et en N du sol complet ainsi que les fractions de matière organique associées aux particules et aux minéraux. Les copeaux d’osier améliorent l’agrégation et la respiration du sol, la concentration de C et de N dans le sol complet, de même que le K assimilable par les plantes. [Traduit par la Rédaction]

期刊介绍: Published since 1957, the Canadian Journal of Plant Science is a bimonthly journal that contains new research on all aspects of plant science relevant to continental climate agriculture, including plant production and management (grain, forage, industrial, and alternative crops), horticulture (fruit, vegetable, ornamental, greenhouse, and alternative crops), and pest management (entomology, plant pathology, and weed science). Cross-disciplinary research in the application of technology, plant breeding, genetics, physiology, biotechnology, microbiology, soil management, economics, meteorology, post-harvest biology, and plant production systems is also published. Research that makes a significant contribution to the advancement of knowledge of crop, horticulture, and weed sciences (e.g., drought or stress resistance), but not directly applicable to the environmental regions of Canadian agriculture, may also be considered. The Journal also publishes reviews, letters to the editor, the abstracts of technical papers presented at the meetings of the sponsoring societies, and occasionally conference proceedings.
