追施海藻叶面肥对盐碱地冬小麦生长及其产量的影响
Effects of Topdressing Seaweeds Foliar Fertilizer on Growth and Yield of Winter Wheat in Saline-alkali Land
摘要
Abstract
[Objective] To investigate the effects of topdressing seaweeds foliar fertilizer on growth and yield increase of winter wheat.[ Method] With spraying clean water as the control, toppdressing of 2.5, 5.0 and 7.5 g/L foliar fertilizer were carried outat wheat jointing stage, heading stage and filling stage, respectively.The wheat growth and yield were observed and compared.[ Result] Spraying the seaweeds foliar fertilizer fertile could increase remarkably the number of winter wheat group, plant height, leaf area, chlorophyll content, nutrient transport capacity, lodging resistance, salt resistance and its subsequent growth ability.Among them, effects of sparying 5.0 and 7.5 g/L foliar fertilizer reached ex-tremely significant level.At the same time, spraying seaweeds foliar fertilizer could increase the biomass yield and grain yield of winter wheat in terms of productive capacity, and treatment effects of 5.0 and 7.5 g/L were extremely effective.[Conclusion] Spraying seaweed foliar fertilizers of medium and high dosage have the best effect.关键词
