摘  要：
主要研究了育苗基质底肥营养对番茄、青椒秧苗生长的影响,探讨了番茄和青椒秧苗生长适宜的施肥方式和合理的施肥量,为穴盘无土育苗生产提供了技术指导。利用基质加不同量复合肥料及碳酸氢钙的处理在番茄和青椒秧苗上进行了田间肥效试验。在育苗基质底肥营养方面,施肥量为40 g复合肥料/10 L基质处理下番茄秧苗的各项指标均最好,而青椒秧苗的株高、茎粗、叶面积及鲜重值均是50 g复合肥料/10 L基质的处理最好,但40 g复合肥料/10 L基质处理的壮苗指数最高;在育苗基质底肥加碳酸氢钙营养方面,钙肥处理番茄和青椒壮苗指数均小于对照,但差异未达到显著水平。40 g复合肥料/10 L基质的处理适宜番茄和青椒秧苗的生长需求;基质底肥加碳酸氢钙处理对番茄和青椒秧苗生长无促进作用。

摘  要：
The effects of base fertilizer substrate nutrition on seedling growth of tomato and green pepper was studied to obtain a proper fertilizer module and formula,and provide technical support for tray soilless seedling raising.Field experiment on fertilization effect was conducted by treading tomato and green pepper seedlings with substrate plus different amount of compound fertilizer and calcium bicarbonate.As referred to the base fertilizer of seedling raising substrate,the best indexes of tomato seedling and the highest rate of strengthen green pepper seedling could be obtained when 40 g complex fertilizer was added to every 10 L substrate;while the plant height,stem diameter,leaf area and fresh weight of green pepper reached the highest when the dose of complex fertilizer was 50 g per 10 L substrate.In the aspect of calcium bicarbonate,the strengthen seedling rate of Ca fertilizer treated tomato and green pepper was lower than that of control,while the difference was insignificant.In conclusion,adding 40 g complex fertilizer in every 10 L substrate was suitable to the seedling growth of tomato and pepper;while adding calcium nitrate had no promotion effect on growth of tomato and pepper seedlings.
