中文摘要：
通过3因素3水平正交试验,研究了灌溉定额、施肥量以及水肥交互作用对宁农科1号西瓜产量的影响。结果表明,土壤质量含水率在11%以上时,不会出现畸形瓜;补灌定额180~360m3/hm2时,产量趋于线性增长;补灌定额180~360m3/hm2、施有机肥量300~1 500kg/hm2、施油渣量300~900kg/hm2条件下,低水配以中肥、中水配以中肥、高水配以高肥具有较好的经济效益。
英文摘要：
Through orthogonal experiments with 3factors and 3levels,the effects of irrigation quotas,fertilizing amount,water and fertilizer interactive effect on yield of Ningnongke No.1watermelon were studied.The results showed that there was no malformation of Ningnongke No.1watermelon when soil moisture was more than 11%;The yield increased linearly when supplement water quota changed from 180m3/hm2 to 360m3/hm2;When the supplement water quotas was between 180m3/hm2 to 360m3/hm2,organic fertilizer consumption was between 300kg/hm2 to 1 500kg/hm2,and oil residue amount was between 300kg/hm2 to900kg/hm2,low supplement water quotas matching with middle fertilizer amount,middle supplement water quotas matching with middle fertilizer amount,and high supplement water quotas matching with high fertilizer amount could gain higher economic benefits.
