摘要
以岩棉为对照,研究了基质配方对樱桃番茄(品种"巍巍")生长发育和产量的影响。采用的基质配方有以下几种:草炭+蛭石(1:2)、草炭+珍珠岩(1:2)、草炭+蛭石+珍珠岩(1:1:1)、蛭石+珍珠岩(2:1)、草炭+沙子+珍珠岩(1:1:1)以及草炭+蛭石+珍珠岩(1:2:1),分别用A、B、C、D、E、F表示。结果表明,供试基质对番茄根系生长发育都有显著的促进作用,A、D、E使单果种明显增加,D使总产量增加。综合分析,基质D是最适宜推广应用的基质配方。
The effects of mixed substrates, i.e. A： peat ＋ vermiculite（1：2）, B： peat ＋ pearlite（1：2）, C： peat ＋ vermiculite ＋ pearlite（1：1：1）, D： vermiculite ＋ pearlite（2：1）, E： peat ＋ sand ＋ vermiculite （1：1：1） and F： peat ＋ vermiculite ＋ pearlite（1：2：1） on growth and yield of tomato （cv. ＂Weiwei＂） were studied. Results showed that all the substrate studied significantly enhanced root growth of tomato in comparison with the control substrate of rock wool; the average single fruit weight were remarkably increased by the substrates of A, D and E; but yield from most of the substrates were lower than that from control, except for the total yield from substrate D, witch was higher than control. Based on the results, we made the conclusion that the substrate of vermiculite ＋ pearlite（2：1） was the optimal one.
