摘要
采用随机区组设计不同灌溉方式处理,并在准确调查降水量、灌水量和土壤贮水量的基础上研究花生膜下滴灌技术的水分利用效率和对产量的影响。结果表明,膜下滴灌较常规灌溉产量提高17.32%;膜下滴灌总水分利用效率为2.044 kg/m^3,较常规灌溉提高23.80%,其灌水的水分利用效率为6.935 kg/m^3。因此,膜下滴灌能改善水分在不同时间的分布,协调植株的营养生长和生殖生长,促进荚果发育。
Different irrigation methods were designed by random block method,and the precipitation,irrigation water amount and soil water storage amount were accurately surveyed to explore the effects of drip irrigation under plastic film on water use efficiency and yield of peanuts. The results showed that the peanut yield of drip irrigation under plastic film treatments improved by 17. 32% compared with conventional irrigation treatments. The total water use efficiency of drip irrigation under plastic film treatments was 2. 044 kg/m^3,which was 23. 80% higher compared with conventional irrigation treatments,among which,the irrigation water use efficiency was 6. 935 kg/m^3. Thus,drip irrigation under plastic film could improve the water distribution at different times,coordinate the vegetative growth and reproductive growth of plants and promote the development of pod.
