摘要
为了研究甜瓜(Cucumis melo L.)节水节肥栽培技术,采用正交试验法,在旱区压砂地上,对膜下滴灌条件下的灌水定额、施肥量和灌水次数3因素进行了最优组合方案比较研究。结果表明,影响甜瓜产量的主要因素是灌水定额,其次是灌水次数和施肥量;方差分析结果表明,试验的最优因素水平组合是灌水定额为37.5 m3/hm2、施肥量为900 kg/hm2、灌水次数为5次。
In order to study the water-saving and save fertilizer cultivation techniques of melon（Cucumis melo L.）, the optimal combination of 3 factors including irrigation quota, fertilizer application and irrigation frequency under the condition of drip irrigation under membrane in the pressure in arid sand land was studied by orthogonal experimental method. The result indicated that the main factor affecting melon production is irrigation quota, followed by irrigation frequency and amount of fertilizer. According to variance analysis of melon physiological characteristics and yield, the optimum combination is irrigation quota 37.5m^3/ hm^2, amount of fertilizer 900 kg / hm^2, and irrigation frequency 5 times.
