- 摘要:
- 以园土、蛭石、珍珠岩和草炭为基质材料，采用随机区组试验，设计10种基质配方，以园土为对照，对欧洲鹅耳枥一年生播种苗进行基质育苗试验，计算育苗成本、记录出苗率、测定植株的干物质积累量、苗高增长量、地径增长量、质量指数等，并对试验指标进行主成分分析，以期筛选出欧洲鹅耳枥一年生播种苗高效低成本基质。结果表明：不同基质的育苗成本、出苗率、质量指数、干物质积累量等差异显著，结合主成分分析结果，处理4(园土∶草炭∶蛭石∶珍珠岩=2∶1∶2∶3)育苗成本最低且苗木质量最好，可以作为欧洲鹅耳枥生产育苗最佳基质参考。
- Abstract:
- Taking garden soil，vermiculite，perlite and peat as matrix materials，using randomized block experiment,designed 10 kinds of matrix formulation，garden soil as contrast to research Carpinus betulus annual seeding seedlings on the matrix of test，calculated the cost of seedling，seedling emergence and determination of amount of dry matter accumulation of plant，growth in seedling height，ground diameter growth，quality index，etc.，and principal component analysis was carried out on the test index，so as to screen out Carpinus betulus annual efficient low-cost substrate of sow.The results showed that the difference of seedling cost，germination rate，the quality index，dry matter accumulation in different substrates was extremely obvious，combinating with principal component analysis，different substrates had different seedling raising cost，No.4 (garden soil，peat，vermiculite，perlite=2∶1∶2∶3)had the lowest cost of seedling and seedling quality was the best，therefore,No.4 was the best matrix of seedling Carpinus betulus with low cost and high efficiency，which could be used as a best matrix Carpinus betulus seedling production reference.
