不同浓度NaCl对矮牵牛穴盘苗生长发育的影响
Effects of Different Concentration of NaCl on Growth and Development of Petunias(Petunia hybrida Vilm) Seedling
摘要
Abstract
[ Objective] The purpose was to study the effects of NaCl on growth and development of petunias seedling, and provide a theoretical guidance for its plug seedling production in a large scale. [Method] NaCl concentration was 0(CK) , 0.25, 0.50, 1.00, 1.25, 1.50 g/L respectively, growth and development of petunias were determined. [ Result] The results showed that low concentration NaCl was help for nutrient uptake of petunias. Among them, the 0.50, 1.00 g/L treatments were the best plant growth vigor, and was significant better than the control. Although 1.25,1.50 g/L treatments plant growth vigor were all better than the control, was obviously poor as 0.50, 1.00 g/L treatments. Determination of matrix EC and its nutrient content showed that NaCl bad a little effects on matrix EC because usually the plug seedlings matrix had ability of buffer capacity to salt, but had significant effects on major element contents. [Conclusion] The low concentration salt contributes to growth and development of plug seedlings, so some city waste water fitting demands can be used to culture the seedlings directly.关键词
