中微量元素肥料对番茄生长及果实品质的影响

为研究中微量元素肥料对番茄提质、增产、抗病等方面的效果,设置常规施肥处理和世多乐中微量元素施肥处理,比较2组处理下番茄的生物学性状和经济性状差异。结果表明,与常规施肥处理组相比较,世多乐施肥处理株高增加14.30%,节间距增加17.04%,均达到极显著差异水平;叶绿素含量、茎粗和叶片厚度分别提升4.03%、3.85%及2.56%;世多乐施肥处理比常规处理667 m~2增产568.09 kg,增产率达30.7%。由此可见,世多乐中微量元素肥不仅能促进番茄的长势,还能提高番茄的产量,可以进一步扩大推广面积。

Effect of Medium and Trace Element Fertilizers on Tomato Growth and Fruit Quality

Abstract: In order to investigate the effects of medium and trace element fertilizers on the quality improvement, yield increase and disease resistance of tomato, a conventional fertilizer treatment and a Stoller medium and trace element fertilizer treatment were set to compare the biological and economic traits of tomato. The results showed that compared to the conventional fertilizer treatment, the plant height increased by 14.30% and node spacing increased by 17.02%, both of which reached highly significant differences by the Stoller fertilizer treatment. In addition, chlorophyll content, stem thickness and leaf thickness increased by 4.05%, 3.80% and 2.16%, respectively. Furthermore, the Stoller fertilizer treatment increased production by 568.09 kg, which higher than the conventional treatment by 30.7% per 667 m2. Thus, the experiment showed that Stoller medium and trace element fertilizer could promote tomatoes'' growth and yield, which could be further expanded.
