通过１９８５～１９８９年在番茄上进行的试验，初步肯定了钛在番茄上叶面喷施的效果和应用技术。叶面喷施１０～２０ｐｐｍ钛两次，对促进保护地、露地番茄早熟增产、优质及提高经济效益效果显著，投入与产出比为１：１９～１４０。钛能使番茄种子萌发提早，幼苗生长加快，根系粗壮，生理活性增强，促进Ｈ２Ｏ２酶活性，有利番茄叶绿素含量增加和光合作用强度提高，果实中ＶＣ和可溶性固形物含量增加等。
Through experiments carried out on tomato from 1985 to 1989, the effect and application technology of titanium spraying on the leaves of tomato were preliminarily confirmed. Foliar application of 10 ~ 20ppm titanium twice, to promote the protection of open-field tomato early yield, high quality and economic benefits of a significant effect, the input-output ratio of 1:19 to 140. Titanium can make tomato seeds germinate earlier, seedling grow faster, root system sturdy, physiological activity increased, promote H2O2 enzyme activity, favorable tomato chlorophyll content and photosynthesis intensity increased, the fruit VC and soluble solids content increased.
