不同基质配比的育苗块对黄瓜幼苗生长发育及其质量的影响

Effect of Matrix Formulations in Seedling Block to the Seedling Growth and Quality in Cucumber

试验利用草炭和蛭石作为基质原料,研究了基质不同配比对育苗块育苗效果的影响。结果表明,不同的基质配比对育苗块的理化性质影响较大,蛭石的添加增加了育苗块的孔隙度、吸水量,对黄瓜秧苗生长发育也有较大影响,有利于提高秧苗质量;草炭与蛭石体积比为5∶1的育苗块具有良好的理化特性,且能够保证秧苗质量。

With the turf and vermiculite as the material to investigate the effects of the different matrix formulation in seedling block to the seedling. The results show that various matrix formulations brought great effect to physical and chemieal properities of the matrix block and the supplement of the vermiculite could increase porosity of the seedling block and moisture absorption, which would improve cucumber seedling growth and eventually seedling quality. The experiment showed when turf to vermiculite in a ratio of 5 ： 1, the seedling block had ideal feature and the seedling quality would be well guaranteed.
