为考察含镁大量元素水溶肥料对茄子生长的影响,以市售的水溶肥料(11-8-32)为对照,开展了田间小区试验,测定了茄子的生长指标、产量指标和品质指标等。结果表明:含镁大量元素水溶肥料处理的茄子株高、茎粗、叶绿素相对含量(SPAD值)、果实纵径、单果质量、单株坐果数、产量等指标均优于对照处理的;果实中硝酸盐含量低于对照处理的,可溶性糖含量差异不显著。施用含镁大量元素水溶肥料可以促进茄子的生长,提高果实的品质。
In order to investigate the effects of macro-element water-soluble fertilizer containing magnesium on growth of eggplant, a field plot experiment is carried out using commercially available water-soluble fertilizer (11-8-32) as a control, and the growth indicator, yield indicator and quality indicator of eggplant are measured. The results show that the eggplant treated with macro-element water-soluble fertilizer containing magnesium has better plant height, stem diameter, relative chlorophyll content (SPAD value), fruit longitudinal diameter, single fruit weight, number of bearing fruits per plant, yield and other indicators than that of the control treatment. When the nitrate content in the fruit is lower than that of the control treatment, the difference in soluble sugar content is not significant. The application of macro-element water-soluble fertilizer containing magnesium can promote the growth of eggplant and improve the quality of fruit.
