不同压力水头下微润灌对大棚大叶茼蒿生长的影响

The Effect of Different Micro-pressure Irrigation on the Growth of Large Leaf Chrysanthemum in Greenhouse

为了探究微润交替灌溉不同压力水头对大棚大叶茼蒿生长发育的影响,试验设置1 m压力水头12 d交替灌溉(A处理)、1.5 m压力水头12 d交替灌溉(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利用率。研究表明:微润灌溉处理组的灌水量可以明显减少,灌溉水分生产率分别为普通灌溉组的3.5倍和2.4倍,且大叶茼蒿的生长优势明显;故就本试验而言1 m压力水头处理组的植株生长情况和产量均高于1.5 m压力水头,但作为一种新型的灌溉技术,微润灌溉在大田上的推广和应用还需做大量的试验来不断验证。

In order to explore the effect of alternate micro-irrigation and different pressure head on the growth and development of Artemisia selengensis in greenhouses,the experiment was conducted with alternating irrigation of 1 m pressure head for 12 days（ A treatment）,alternate irrigationof 1.5 m pressure head for 12 days（ B treatment） and normal irrigation（ C treatment） three different treatments,each treatment repeated three times to analyze the growth of Artemisia selengensis and irrigation water utilization. The results show that Micro-irrigation irrigation treatment group of irrigation can be significantly reduced,the irrigation water productivity is 3.5 times and 2.4 times than that of ordinary irrigation,and the growth advantage of Artemisia major is obvious; In this experiment,the plant growth and yield of 1 m pressure head treatment group were both higher than the pressure head of 1. 5 m,but as a new type of irrigation technology,a lot of experiments need to be done to constantly verify the application and promotion of micro-irrigation in the fields.
