Effects of irrigation threshold and fertilization on growth, yield and physiological properties of fertigated tomato in greenhouse
摘要
Abstract
For the purpose of exploring the effective mode of fertigation in greenhouse, the experiment was conducted to analyze the effects of different irrigation threshold and fertilization on growth, physiological properties and yield of tomato. There were three irrigation threshold treatments including W1 (65% θF) , W2 (75% θF) and W3 (85% θF) , and three fertilization treatments including F1 (low) , F2 (middle) and F3 (high) . The results showed that the growth, yield and physiological properties of tomato could be modified by different irrigation threshold and fertilization. Under certain irrigation threshold, the plant height, leaf area, photosynthesis and transpiration rate, dry matter production and yield of tomato could be significandy increased along with the increase of fertilization amount, while excessive fertilization was detrimental to the growth, dry matter accumulation and yield improvement of tomato. Under certain fertilization amount, the plant height, leaf area and dry weight of tomato could be improved by rational increase of irrigation threshold, while excessive irrigation threshold was not conducive to the growth, photosynthetic rate and yield improvement of tomato. The treatment of W2F2 was most conducive to the growth, dry matter accumulation, yield and water use efficiency of tomato. The experiment also showed that, under different water and fertilization treatments, there was a significant linear correlation between the yield and dry matter weight as well as leaf net photosynthetic rate, and there was a significant quadratic parabola correlation between the leaf water use efficiency and net photosynthetic rate.关键词
