摘要
在微润灌溉的前提下,为了探究不同灌水方式对大棚辣椒生长发育的影响,本试验在双管布设前提下,设置交替灌溉(A处理)、间歇性灌溉(B处理)、持续灌溉(C处理)和普通灌溉(D处理) 4个不同处理,每个处理重复试验3次,分析辣椒的生长状况以及灌溉水分利用率。研究表明:微润灌溉处理组的植株生长情况和产量均高于普通灌溉组,其中灌溉水分生产率分别为普通灌溉组的2.13倍、3.08倍和2.97倍;间歇性灌溉的灌溉水分生产率最高。
Under the premise of micro-wetting irrigation,in order to explore the effects of different irrigation methods on the growth and development of greenhouse peppers,this experiment set up 4 different treatments,including alternate irrigation (A treatment),intermittent irrigation (B treatment)and continuous irrigation (C treatment)and general irrigation (D treatment)and each treatment was repeated 3 times to analyze the growth status and irrigation water utilization efficiency of pepper.The results showed that the plant growth and yield of the mild irrigation treatment group were higher than that of the general irrigation group,and the irrigation water productivity was 2.23times,3.08 times and 2.97times of that of the general irrigation group.The irrigation water productivity of the intermittent irrigation was the highest.
