基于微润灌不同交替周期对大棚大叶茼蒿生长的影响

Effects of Alternation Cycle of Micro-irrigation on The Growth of Large leaf Chrysanthemum in Greenhouse

在微润灌溉前提下,为了探究不同交替灌溉的周期对大棚大叶茼蒿生长发育的影响,试验设置1 m压力水头6 d交替灌溉周期(A处理)、1 m压力水头12 d交替灌溉周期(B处理)和普通灌溉(C处理)3个不同处理,每个处理重复试验3次,分析大叶茼蒿的生长状况以及灌溉水分生产率。研究表明:就本试验大叶茼蒿而言微润灌溉处理组的灌水量可以降低约35.6%,灌溉水分生产率分别为普通灌溉组的2.62倍和3.96倍,且大叶茼蒿的生长优势明显;12 d的交替周期更有利于大叶茼蒿生长。

Under the condition of micro-irrigation, in order to explore the effects of different alternate irrigation periods on the growth and development of large leaf chrysanthemum in greenhouse, an experiment was conducted with 3 treatments, including the 6-day alternating irrigation period with lm pressure head （A treatment）, the 12-day alternate irrigation period with lm pressure head （B treatment） and the normal irrigation （C treatment）. And each treatment was repeated for three times to analyze the growth of large leaf chrysanthemum and irrigation water productivity. The results show that the irrigation amount of micro-irrigation can be reduced by 35.6%, the irrigation water productivity reaches 2.62, which is 3.96 times of that of ordinary irrigation, and the growth of large leaf chrysanthemum has obvious advantages; the alternate cycle of 12 days is more conducive to the growth of large leaf chrysanthemum.
