| Abstract: |
| 【Objective】 Soil water controls growth and physiological development of all plants and the purpose of this paper is to elucidate how different irrigation amounts affect the grow traits and yield of seeding-watermelon.【Method】 We experimentally examined five irrigation amounts: 300 m3/hm2 (W1) , 375 m3/hm2 (W2), 450 m3/hm2 (W3), 525 m3/hm2 (W4) and 600 m3/hm2 (W5) . For each treatment, we measured the growth and the yield of the seeding-watermelon, as well as its water consumption and water use efficiency (WUE). Fuzzy comprehensive method was used to evaluate the experimental results. 【Result】 Different irrigation amounts had different influences on the length of main vine and the number of non-principal vines. The growth indexes increased with the irrigation amount, with the treatment W5 having most significant impact followed by W4. There was no significant difference in the growth indexes between W4 and W5 during the bud extension and fruit expansion stages. The yield and WUE were highest under W4, followed by W5. Compared with W5, W4 increased the growth and hence the production of the seeding-watermelon.【Conclusion】 Our experimental results and the fuzzy analysis both revealed that W4 is the most suitable irrigation methods for the seedling-watermelon. |
