不同基质配比对芹菜幼苗生长发育的影响

Effects of different substrate on the growth of seedlings of celery

本试验就芹菜无土育苗中基质因子对幼苗生长的影响进行了研究,在泥炭∶蛭石=2∶1;泥炭∶炉渣∶蛭石=1∶1∶1;泥炭∶沙=1∶1;泥炭∶蛭石∶珍珠岩=1∶1∶1四种育苗基质中,进行育苗种植。试验结果表明,以泥炭+蛭石基质结合营养液的芹菜苗质量最好。即茎粗、叶面积、全株干物重和壮苗指数均等于或接近各测量项目中的最大值,幼苗综合质量最佳。

this experiment celery Soilless Seedling factor of the influence on the seedling growth in Peat：vermiculite,=2：1;peat：vermiculite slag=1：1：1;peat： sand=1：1;peat：vermiculite：pearlite=1：1：1 of four seedling matrix,for seedling planting.Experimental results show that peat＋vermiculite substrate binding, nutrient celery seedling quality best.The stern diameter,leaf area,total plant dry weight and seedling index were equal to or close to the maximum value of each measurement in the project,the seedling qualities best.
