几种无土栽培甜椒基质的比较

Comprison between Several Substrates on Soilless Culture of sweet Pepper

以炉渣∶草炭 (体积比 ) =3∶2、花生壳∶蛭石∶珍珠岩 =5∶3∶2和玉米芯∶蛭石∶珍珠岩 =5∶3∶2等 3种类型的复合基质进行甜椒无土栽培的比较研究。结果表明 :不同类型的复合基质所栽培的甜椒生长发育、产量分布和总产量均有明显差别。以工业废弃物为主的炉渣∶草炭 =3∶2的前期产量达 1174 5kg/hm2 ;花生壳∶蛭石∶珍珠岩 =5∶3∶2的复合基质则获得最高的商品果总产量 ,达 4 2 75 3kg/hm2 ,比对照增产 2 0 .3% ,果实的Vc含量为最高 ,是甜椒无土栽培的适宜基质配方。

s Three different types of substrates obtained through three formulae,slag∶peat=3∶2,peanutshell∶vermiculite∶perlit=5∶3∶2 and corncob∶vermiculite∶perlite=5∶3∶2,were used in sweet pepper soilless culture. The results are as follows: Plant cultivated in substrate in which inorganic material is the main component grows fine during early stage and the yield is superior to that of control. Slag∶peat=3∶2 gets the highest early yield(11 745 kg/hm 2).The substrate including peanshell got the highest yield(42 753 kg/hm 2), increasing by 20.3% compared with the control's yield. Vc is also superior to that in the control's. Peanshell∶vermiculite∶perlite=5∶3∶2 is an appropriate substrates formula for sweet pepper soilless culture.
