木本泥炭促进设施番茄生长和改良土壤的效果

摘要

针对设施菜田土壤连作障碍、蔬菜品质降低等问题,以北京郊区春大棚番茄为研究对象,通过基施木本泥炭及其他添加物料作土壤调理剂,研究其对番茄产量、品质以及设施土壤改良效果的影响.结果表明:木本泥炭+苛性钾处理较常规施肥处理番茄产量显著增加16.73%,果实VC含量显著增加55.77%,同时明显增加了耕层土壤速效磷、钾养分含量,提高了pH值,而单施木本泥炭、木本泥炭+米糠菌剂处理与常规施肥处理均无显著差异.施用木本泥炭及其他添加物料均有降低土壤表层盐分累积的趋势.综上,施用木本泥炭及其他配合物料对设施番茄生长以及土壤改良有良好的促进作用,其中木本泥炭+苛性钾处理效果最佳.%Aiming at obstacles of vegetable soil after successive cropping and deterioration of vegetable quality in greenhouse,this paper takes tomato(Lycopersicon esculentum Mill.)grown in a greenhouse at outskirts of Beijing in spring as research objective,and studies the effect of wood peat and other material as soil conditioners on tomato yield,quality and facility soil improvement.The results showed that the yield of tomato treated with wood peat plus potassium hydroxide(WP+KOH)increased 16.73%,and the VC content increased 55.77%.Meanwhile,the WP+KOH treatment also increase the contents of soil available nutrients and pH.The treatments of wood peat,wood peat plus fungicide had no significant effects on fruit yield and quality and available nutrients.All treatments by wood peat and other additional material had the trend of reducing soil surface salt accumulation.Therefore,wood peat and its material mixture had a positive effectiveness on greenhouse tomato growth and soil improvement.The WP+KOH treatment was the best.
