摘要
以碎工业岩棉、珍珠岩:草炭(体积比)=3:2、炉渣:草炭=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5种复合基质进行番茄无土栽培的研究。结果表明:在栽培过程中,基质容重均有不同程度的增大;不同复合基质所栽培番茄的营养生长、生理活性、产量分布、总产均有显著差异,在结果初期,复合基质(花生壳:蛭石:珍珠岩=5:3:2)栽培的番茄的鲜质量(705.24g/株)、干质量(73.871g/株)和叶面积(7654.5cm2/株)均为最大,与对照有显著性差异。5个处理番茄前期的产量都低于对照,其中以炉渣:草炭=3:2的前期产量较高,达到23859.0kg/hm2,总产以花生壳为主的复合基质最高,折合78210.0kg/hm2,比对照高出23.9%,差异达到极显著水平;糖酸比以炉渣:草炭=3:2处理的最高,达7.58,而以花生壳为主的复合基质Vc含量最高,达0.1015mg/g。
Five mixed substrates formula： rockwool, perlite：peat=3：2, slag：peat=3：2, peanutshelhvermiculite： perlite= 5：3：2 and corncob：vermiculite：perlite=5：3：2 are conducted in tomato soilless culture. The results are as follows. Bulk density of five treatment increases by different degree during cultivation. The growth properties, photosynsythesis , chlorophyll content , root activity and yield of tomato have significant difference among different formula. Fresh mass, dry mass and leaf area of tomato plant cultivated in peanutshelh vermiculite：pedite=5：3：2 reach 705.24 g/plant, 73.871 g/plant, 7654.5cm^2/plant respectively, which have significant difference compared with control＇s. The early yield of five treatment are lower than control＇s, of which the treatment of slag：peat=3：2 gets higher early yield and it reaches 23859.0 kg/hm^2. The treatment of peanutshelhvermiculite：perlite=5：3：2 gets the highest total yield（78210.0 kg/hm^2）, increasing by 23.9 per cent compared with control＇s yield. The tomato cultivated in slag：peat=3：2 gets the highest sugar/acid （7.58） and cultivated in peanutshelhvermiculite：pedite=5：3：2 gets the highest Vc content（0.1015 mg/g）.
