Abstract:
Secondary salinization and soil sickness in greenhouse soil is increasing seriously，rock wool soilless culture is one of the ways to solve the problem.The effect of different relative water capacity(30%，40%，50%，60%，70%) of rock wool block on the growth of tomato seedlings height，stem diameter，fresh weight，dry weight were studied by using the tomato cultivar ‘Shuangkang No.1’ as experiment material in greenhouse.The results showed that high water capacity of rock wool block had obviously increased the tomato seedlings plant height.Tomato seedlings stem diameter was no significant between the different treatments at the end of the seedlings nurse.High water capacity treatment could significantly increase the over ground fresh weight and dry weight of tomato seedlings，significantly promote root growth，increase root density at the rock wool block underside.60%-70% of rock wool block relative water capacity could be used to tomato seedlings nurse in tomato rock wool soilless culture.
