| 摘 要： | 以珍珠岩∶草炭(体积比)=3∶2、花生壳∶蛭石∶珍珠岩=5∶3∶2、玉米芯∶蛭石∶珍珠岩=5∶3∶2等3种复合基质进行番茄无土栽培的比较研究.结果表明:在栽培过程中,3种复合基质容重、持水孔隙度均有不同程度的增大,而通气孔隙度和总孔隙度则呈下降趋势;对照栽培的番茄前期产量最高,达到22 891.5 kg/hm2,总产以花生壳为主的复合基质最高,折合78 210.0 kg/hm2,比对照高11.9%,与对照差异达显著水平,且果实的Vc含量和糖酸比略高于对照.

| Abstract: | Three mixed substrates formulas such as perlite∶peat=3∶2,peanutshell∶vermiculite∶perlite=5∶3∶2 and corncob∶vermiculite∶perlite=5∶3∶2,were prepared and used for tomato soilless culture.The results showed that the bulk density and water-filled porosity of three mixed substrates increased in different degree during soilless cultivation of tomato,but the air-filled porosity and total porosity decreased.The early yield of tomato under the control cultivation was the highest,which reached 22 891.5 kg/hm2.The treatment of peanutshell∶vermiculite∶perlite=5∶3∶2 had obtained the highest total yield(amounting to 78 210.0 kg/hm2),increasing by 11.9 % more than the control′s yield and the difference was significant.Its Vc content and sugar/acid in the fruits were a little higher than those of control's. |
