| Abstract: Effects of different irrigation and drainage schemes on the quality, water production and tomato yield were
observed. Additionally, entropy weight coefficient method were introduced for the optimal selection of irrigation and
drainage scheme. The results showed that the tomato yield decreased with the decreasing of irrigation amount, while the
content of soluble solids, Vc and ratio of sugar over acid increased significantly. Meanwhile, water production of tomato was
dramatically increased with the decreasing of water application. Except for the total acid content, other quality indexes
increased with drainage buried depth increasing. According to the calculation results of the model, T2 was the best
irrigation and drainage scheme with optimal comprehensive effect, entropy evaluation value of T2 reached 0.948 |
