中文摘要:
      在日光温室中采用沟灌、滴灌、渗灌、小孔出流4种灌溉方法,通过对比试验研究了不同灌溉方法在不同土壤水分控制范围内对茄子生长、产量及水分利用效率的影响,并利用数理统计方法对试验结果进行了分析。研究得出:可以优先选择的4种灌溉处理组合为CT1>DT2>CT3>CT2,其中CT1(即渗灌条件下)当土壤水分控制范围在田间持水量的55%~65%(开花着果期)和田间持水量的65%~75%(结果期)时,茄子长势良好,其产量较相同水分处理下沟灌增产17%;且水分利用效率最高,分别为其他优选灌溉处理组合的1.12倍、1.38倍和1.37倍。
英文摘要:
      Based on mathematical statistics,this paper analyzes the effects of different soil moisture in greenhouse on eggplant growth,yield and water use efficiency under four different kinds of irrigation methods: furrow irrigation,drip irrigation,sub-irrigation and small tube flow irrigation. The results show that: The priority for selection of the four kinds of irrigation treatments is CT1>DT2>CT3>CT2.Among these treatments,in CT1 the sub-irrigation condition,when the soil moisture range is from 55%θf to 65%θf in blossom stage and fruit-set and from 65%θf to 75%θf in fruiting stage,the eggplants grow better;its yield increases by 17% compared with furrow irrigation.Moreover its water use efficiency is the highest,which are respectively 1.12 times,1.38 times and 1.37 times of other priority selected treatments.
