摘　　要：在温室大棚中利用不同浓度的营养液对番茄进行无土栽培,营养液浓度分别为T1(1∶20)、T2(1∶50)、T3(1∶100)、T4(1∶150)、T5(1∶200)。每7d对试验样品进行取样,检测根、茎、叶中磷元素的分布特征,以及植株的株高与茎粗。结果表明,T4(1∶150)的营养液最有利于番茄的生长,磷元素过高会抑制番茄植株的生长,过低会使番茄营养不足,也不利于其生长。该研究为科学施肥、合理种植提供理论依据。Soilless tomato was cultivated in greenhouse with nutrient solution of different concentrations at T 1(1 ∶20),T 2(1 ∶50),T 3(1 ∶100),T 4(1 ∶150),T 5(1 ∶200).The test samples were sampled every 7 days to detect the distribution characteristics of element P in roots, stems and leaves, as well as plant height and stem diameter.The results showed that the nutrient solution of T 4(1 ∶150) was the most beneficial to the growth of tomato, the high P element could inhibit the growth of tomato plants, and the low P element could make the tomato plants lack of nutrition, which was also not conducive to the growth.This study provides theoretical basis for scientific fertilization and rational planting.
