| 摘 要： | 对比研究了进口基质与东北草炭,东北草炭与蛭石、珍珠岩配成的混合基质以及东北草炭与保水剂混合后在40℃恒温下的水分运动特性。结果表明:进口基质的保水性明显优于东北草炭;在东北草炭中加入20%的蛭石时,东北草炭的保水性能达到了与进口基质相类似的水平;而且在东北草炭中加入5 g.kg-1保水剂也能达到与进口基质相类似的水分散失曲线,从而为穴盘育苗基质的国产化和标准化生产奠定了基础。 |

| Abstract: | Water vapor characteristics at 40℃ constant temperature in Dongbei peat-moss and imported substrate,and Dongbei peat-moss mixed with vermiculite or perlite or absorbent polymer were compared in this study.The results showed that: water-keeping capacity of imported substrate was better than Dongbei peat-moss;and when added 20% vermiculite in Dongbei peat-moss,the water vapor characteristics of substrate could reach that in the imported substrate;and when Dongbei peat-moss mixed with 5 g·kg~(-1)absorbent polymer,the water vapor characteristics of substrate were also very similar to that of the imported peat.Therefore,it lay a foundation for the standardization and homemading of substrate for plug production. |
