| 中文摘要: |
| 2009年在宁夏中卫香山乡采用田间试验的方法,比较了穴施和条施生物有机肥对压砂西瓜生长及产量的影响。结果表明:与条施生物有机肥相比,穴施条件下,西瓜生育前期叶面积指数增加了80%~119%;生育中后期主蔓长20.6 cm,增加25.4%;叶片数也较多;单瓜重增加了43%,中心糖含量和边糖含量分别提高了9%和8%;同时西瓜水分生产效率提高了20 kg/(mm·hm2),增加幅度达37%。说明,在压砂地上施用生物有机肥80 kg/667 m2条件下,穴施比条施更有利于促进西瓜的生长,提高西瓜产量,品质和水分利用效率。 |
| 英文摘要: |
| A field experiment was carried out to compare the effects of hill placement of bio organic fertilizer with
that of band placement on watermelon growth and yield at Zhongwei of Ningxia Hui Autonomous Region in 2009. The re-sults showed that the main stem of watermelon was 20.6 cm longer with hill placement of bio organic fertilizer than that with band placement，increasing by 25.4% in the late growth stage. The leaf number of watemnelon was greater also. Leaf area index of watermelon increased by 80%~119% with hill placement compared withband placement in the early growth stage and single melon weight increased by 43%, the sugar content in the center and edge improved by 9% and 8% respectively. At the same time，the water use eficiency of waternelon increased 20 kg/ (mm·hm2) by 43%. In a word, compared with band placement, hill placement of bio organic fertilizer promotes watemelon growth，increases wa-termelon yield and quality and enhances water use efficiency of watemnelon on the condition of the application of 80 kg per 667 m2 on the gravel-mulched land. |
