提高种植草莓在某些系统的水分利用效率

作者(年代):Evon K。Rizk, S.H.Seidhom

这个调查是为了比较两个种植系统和灌溉模式的影响和持续时间(倍)提高水分利用效率的草莓。两个系统;soil-less和土壤文化生长在莎Zuwayid研究站,埃及西奈半岛北部。在随机完整块设计两个实验进行了三个复制。治疗方法包括两个栽培系统为主要情节:A)作为次级地块土壤的文化系统和灌溉模式;滴灌systemtherewere三次每天灌溉,即。(T1) 1/4小时(T2) 1/3小时(T3) 1/2小时沥干架放电4 l /小时,B)无土栽培系统deep-flow技术(DFT)和间歇循环(DFT / IC)为主要情节,和次级地块三每天灌溉时间持续时间即;(D1) 1/4小时(4次)、(D2) 1/3小时(3次)和(D3)半小时(两次)DFT水培法系统是一个封闭的系统。结果统计分析。从实验中,以下结果:土壤培养显著差异在所有的治疗方法,但无显著差异在无土栽培的草莓水果产量。 The magnitude is in the order: T2 > T1 > T3 and D2 > D1 > D3 for the two trials. Strawberry produced higher fruit yield in soil-less culture than the conventional system. Significant decrease in water consumptive use of strawberry by decreasing irrigation times in the order of T1< T2 < T3 in soil culture system. But in soil-less culture system the water consumptive use value significantly decreased by increasing irrigation duration and decreasing the number of irrigation cycles, in the order of D3 < D2 < D1. Significant increase in water use efficiency of strawberry by decreasing irrigation times in the order of T1> T2 > T3 in soil culture system. But in soilless culture system the WUE value significantly increased by increasing irrigation duration and decreasing the number of irrigation cycles, in the order of D3 > D2 > D1. It is suggested to cultivate strawberry plants and irrigate dailywith one liter per plant in soil culture and twice at times of half an hour under the conditions of hydroponics system DFT in closed system at open field in El-Sheikh Zuwayid to obtain the highest water use efficiency. From the economic point of view, applying daily irrigation water amount of 1.33 liter per plant in soil culture and at times of 1/3 hour 3 times in soil-less culture leads to the highest investment ratio (IR).
