育苗基质配比对生姜幼苗的影响

    Influence of Seedling Substrate Ratio on Ginger Seedlings

    • 摘要: 以筛选适配湖南地区生姜穴盘育苗、兼顾经济成本与育苗质量的复合基质配方为目标,旨在为当地生姜集约化育苗提供理论支持与技术参考。试验以商品育苗基质作为对照(CK),选用草炭、蛭石和珍珠岩为原料,按不同比例配制了11种复合基质进行穴盘育苗试验。育苗结束后测定各处理幼苗的形态特征、农艺性状及相关生理指标。结果表明:各基质理化性质总体符合育苗基本要求。为全面评估生姜幼苗在穴盘育苗条件下的生长状况,运用主成分分析方法,对幼苗的各项指标展开综合分析并计算得出综合得分。基于此,生姜幼苗各项指标的综合排名依次为:T11>T1>CK>T6>T9>T3>T10>T7>T8>T2>T5>T4。进一步分析表明,在生姜穴盘育苗实践中,复合基质的最佳配比为 T11,即草炭、蛭石和珍珠岩的体积比(V草炭∶V蛭石∶V珍珠岩)为 3∶2∶2。

       

      Abstract: This study aimed to screen the compound substrate formula which was suitable for ginger plug seedling raising in Hunan area, and that took into account both the economic cost and seedling quality, in order to provide theoretical support and technical reference for the local ginger intensive seedling raising. In the experiment, the commercial seedling substrate was used as the control (CK), and peat, vermiculite and perlite were selected as the raw materials to prepare 11 kinds of composite substrates in different proportions for plug seedling test. After the end of raising seedling, the morphological characteristics, agronomic traits and related physiological indexes of the seedlings under different treatments were measured. The results showed that the physical and chemical properties of each substrate generally met the basic requirements of seedling raising. In order to comprehensively evaluate the growth status of ginger seedlings under the condition of plug seedling, the principal component analysis method was used to comprehensively analyze the indicators of seedlings and calculate the comprehensive score. Based on this, the comprehensive ranking of each index of ginger seedlings was as follows: T11>T1>CK>T6>T9>T3>T10>T7>T8>T2>T5>T4. The further analysis showed that in the practice of ginger plug seedling, the best ratio of composite substrate was T11, that was, the volume ratio of peat, vermiculite and perlite (V peat ∶ V vermiculite ∶ V perlite) was 3 ∶ 2 ∶ 2.
