摘要
采用基质育苗的方式研究了不同钾水平对番茄幼苗生长的影响。结果表明:适当提高基质中钾肥浓度,可提高番茄幼苗的干物质积累,提高根系活力。但基质中钾肥浓度过高时,幼苗的生长势降低。在本试验条件下,以K2O浓度为30g/m2为最佳的钾肥施用浓度。
The effects of different concentration potassium fertilizers on the seedlings growth of tomato were studied with soilless culture. The results showed that the proper K application treatment can promote dry weight of the seedlings, and improve vigor of root. But in excessive K application treatment, growth of tomato seedlings were decreased. In this experiment, K7 （K2O 30 g/m^2） was the best treatment.
