蔬菜穴盘育苗具有生产效率高、秧苗质量好、移栽缓苗快和操作简便等优点,适于工厂化和规模化生产需要,特别适合在茄果类、瓜类蔬菜生产中应用。在育苗过程中,壮苗指数是评价幼苗生育质量的综合指标,与蔬菜产量和抗逆性的相关性显著,而育苗基质中的养分含量是影响幼苗壮苗指数的关键因素。为此,我们于2000～2001年应用正交试验设计方法,对穴盘育苗基质中施用不同浓度的氮、磷、钾肥料与黄瓜、番茄、茄子和甜椒等蔬菜壮苗指数的关系进行了研究,以探讨蔬菜穴盘育苗基质的施肥技术。材料与方法育苗基质为60%草炭+30%蛭石+10%珍珠岩混合而成,穴盘采用72孔(6×12孔)标准育苗盘,
Vegetable plug seedling has the advantages of high production efficiency, good quality of seedlings, fast transplanting Huanmiao and easy operation, suitable for factory and large-scale production needs, especially suitable for eggplant, melon vegetables production applications. In the process of raising seedlings, the strong seedling index is a comprehensive index to evaluate the seedling quality, and has significant correlation with the yield and stress resistance of the vegetables. The nutrient content in the seedling matrix is the key factor that affects the seedling growth index. To this end, we applied the orthogonal experimental design method from 2000 to 2001 to study the relationship between the strong, medium and low concentration of nitrogen, phosphorus and potassium fertilizers and cucumber, tomato, eggplant and pepper in seedling culture substrate Research to explore vegetable plug seedling substrate fertilization technology. MATERIALS AND METHODS The nursery substrate was composed of 60% peat + 30% vermiculite + 10% perlite mixed with a standard seedling tray of 72 holes (6 × 12 holes)
