根据植物生长需要和华南地区水质，设计8种肥料配方进行蕹菜水培试验，探讨不同肥料配方对蕹菜的生物学性状、生理指标、产品品质和产量的影响。结果表明，以6号和7号配方供肥，蕹菜长势旺盛、产量高、根系活力强，叶绿素含量适中。各处理蕹菜中的抗坏血酸含量高，NO3-，NO2-含量低，符合国家洁净蔬菜标准。
According to the needs of plant growth and the water quality in South China, eight kinds of fertilizer formulas were designed for the water spinach experiment to investigate the effects of different fertilizer formulas on the biological traits, physiological indexes, product quality and yield of water spinach. The results showed that with No. 6 and No. 7 formulas for fertilizer, the growth vigor of Brasenia schreberi, high yield, strong root activity, moderate chlorophyll content. The high content of ascorbic acid in various treatments of Brasenia schreberi, low NO3-, NO2- content, in line with the national clean vegetable standards.
