不同生物有机肥施肥方法对压砂西瓜生长及产量的影响
Effects of different methods of bio-organic fertilizer application on watermelon growth and yield on gravel-mulched land
摘要
Abstract
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 results 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 watermelon 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 efficiency of watermelon increased 20 kg/(mm*hm2) by 43% . In a word, compared with band placement, hill placement of bio-organic fertilizer promotes watermelon growth, increases watermelon yield and quality and enhances water use efficiency of watermelon on the condition of the application of 80 kg per 667m2 on the gravel-mulched land.关键词
