摘要
采用岩棉和营养土方作育苗基质,观测了基质对番茄幼苗各时期生长的影响。其试验结果是:以岩棉作基质培育幼苗能增加番茄幼苗全株的于重,其中幼苗根系的干重增加较为显著。在播种24d内,岩棉育苗的幼苗高度、茎干重、叶面积和干重的增长略低于营养土方育苗;24d以后,岩棉育苗则增长迅速。说明岩棉育苗具有增加幼苗干物质累积、培育壮苗的特点,证实岩棉是一种良好的育苗基质。
Rockwool and nutrient soil blocks were used for the substrates of the cultivating seedlings of tomatoes. Effects of two cultural substrates on tomato seedlings were observed. The results indicated that increments of seedlings on rockwool culture were lower than those on nutrient soil culture on dry weight of shoot-leaves, leaf area and shoot height during 24 days after seed sowed. However after 24 days,increments of the shoot-leaves,leaf area and shoot height on rockwool culture were much more than those on nutrient soil culture. Root dry weight on rockwool culture was weightier than that on nutrient soil culture during the cultivating seedlings of tomatoes. Rockwool as a substrate is better for cultivating tomato seedling.
