摘要
【目的】探明微润灌毛管6种布设方式对新定植红枣生长的影响规律,为低压微润灌工程设计、技术应用和生产管理提供技术依据。【方法】采取不同的毛管布设方式,针对新定植红枣进行微润灌应用研究,观测微润灌溉条件下的土壤含水量分布状况及新定植红枣的各项生理指标。【结果】处理四(管距30 cm埋深30 cm)红枣幼苗成活率及根系生长幅度较优于其他处理,成活率达49.6%、根幅范围达50 cm。株高累计生长量达4.04 cm。综合评价其指标,最优的微润灌毛管布置方式为处理四。【结论】微润灌作为一种新的灌水技术,有其一定的技术优势,但在大田作物上推广应用,还需做大量的试验来进行验证。
【Objective】To research the effects of different layout methods of micro- run irrigation tube on the growth of newly- planted date trees in order to provide the technical basis for the low- pressure micro- run irrigation project design,technology appliance and production management. 【Method】Different layout methods of micro- run irrigation tube were adopted to do research on new planting date trees and the soil moisture distribution and the physiological indicators of newly- planted dates under the micro- run irrigation condition were observed. 【Result】The method four sample＇s survival rate and root elongation were better than other treatments,the survival rate was 49. 6%,and root elongation range was up to 50 cm. Height was increased 4. 04 cm. Comprehensive evaluation of those results showed that the best layout method was the fourth one. 【Conclusion】As a new irrigation technology,micro- run irrigation has certain technical advantages,but a lot of tests still needed to be done before this technology is applied to field crops.
