不同水溶肥种类及浓度对番茄幼苗生长的影响
Effects of Different Water-Soluble Fertilizers and Concentrations on the Growth of Tomato Seedlings
摘要:
为探究适合番茄高效育苗的营养管理方法，本试验施用5种水溶肥和最适水溶肥的5个浓度，研究其对番茄幼苗生长的影响。结果表明，“莱瑞”水溶肥处理下的番茄幼苗的叶片SPAD值、地上部鲜重和茎粗均优于其它4种水溶肥；施用1倍浓度的“莱瑞”水溶肥，番茄幼苗的地上部和地下部鲜重、茎粗和壮苗指数均显著高于其它浓度处理。综合幼苗的生长状况、种苗质量和水溶肥的价格，1倍浓度的“莱瑞”水溶肥最适合番茄优质高效育苗。
Abstract:
In order to explore the nutrient management method suitable for tomato seedlings with high efficiency, five kinds of water-soluble fertilizers and five optimum concentrations of water-soluble fertilizers were applied in this experiment, to study their effects on the growth of tomato seedlings. The results showed that the leaf SPAD value, shoot fresh weight and stem diameter of tomato seedlings treated with “Lairui” water-soluble fertilizer were better than those of the other four water-soluble fertilizers. The fresh weight, stem diameter and strong seedling index of tomato seedling with one time concentration were significantly higher than those of other concentration treatments. Considering the growth status of the seedlings, the quality of the seedlings and the price of the water-soluble fertilizer, the “Lairui” water-soluble fertilizer with one time concentration is the most suitable for high-quality and efficient tomato nursery.
