摘要
[目的]探索砂田辣椒的适宜补水量。[方法]通过田间试验研究了不同补水量对砂田辣椒生长发育、水分利用效率(WUE)及产量的影响。[结果]随补水量的增加,辣椒的生育期延长,叶面积增加,株高增加,光合速率及蒸腾速率增加,补水量为225～375m3/hm2时达到最佳。WUE在补水量为225m3/hm2时达到最大,辣椒产量也随补水量的增加而增加,在补水量为375m3/hm2时达到最大,此时产量为21000kg/hm2,产值达到18000元/hm2,比砂田西瓜高约10200元/hm2。[结论]考虑到砂田补充水分的困难和水资源有限,认为砂田辣椒的补水量在300～375m3/hm2比较合适。
[Objective] The research aimed to find appropriate additional water amount for hot pepper.[Method] Through field trials,effects of different additional water amount on growing period,water use efficient and yield of hot pepper in sandy-field were studied.[Result] With additional water amount increased,not only growing period extended but also leaf area,plant height,photosynthetic rate and transpiration rate increased,which reached the best when additional water amount was 225-375 m^3/hm^2.WUE reached the maximum when additional water amount was 225 m^3/hm^2,and the yield was 21 000 kg/hm^2 that was the highest when additional water amount reached 375 m^3/hm^2,value of output reached 18 000 yuan per hectare which was 102 000 yuan higher than watermelon.[Conclusion] To take into account the capacity of added moisture in sandy field was limited and hardly,appropriate additional water amount was 300-375 m^3/hm^2.
