不同微润灌溉周期下辣椒根系生长与产量的关系

Relationship between Root Growth and Yield of Pepper under Different Micro-Irrigation Periods

为了探究微润交替灌溉不同交替周期和不同压力水头对大棚辣椒根系生长的影响,设置1 m压力水头4d交替灌溉(A处理)、1 m压力水头8d交替灌溉(C处理),1.5 m压力水头4 d交替灌溉(B处理)、1.5 m压力水头8d交替灌溉(D处理),双管灌溉(E处理)和普通灌溉(F处理)6个不同处理,每种处理重复3次,分析辣椒根系生长情况,以及根系的生长发育对辣椒产量的影响。研究表明:微润灌溉处理的灌溉水分生产率均高于普通灌溉,其中双管灌溉试验组的灌溉水分生产率最高。

In order to investigate the effect of different alternating cycles and different pressure head on the root growth of pepper in greenhouse, six different treatments, including 1 m pressure head with 4 days alternating irrigation （A treatment）, 1 m pressure head with 8 days alternating irrigation （C treatment）, 1.5 m pressure head with 4 days alternating irrigation （B treatment） , 1.5 m pressure head with 8 days alternating irrigation （ D treatment）, double pipe irrigation （ E treatment ） and ordinary irrigation （ F treatment ） were set and each treatment was repeated three times to analyze pepper root growth and the effects of root growth and development on pepper yield. The results show that the irrigation water productivity of micro- irrigation is higher than that of ordinary irrigation. The irrigation water productivity of the double - tube irrigation experiment group was the highest.
