摘要
选取灌溉水费、电费、人工费、试验周期、单果重、果实糖度、果实维生素C含量以及根系状况为评价指标,利用主观赋权法与熵权信息法相结合的综合评价方法对不同土壤条件下循环曝气滴灌盆栽草莓综合效益进行评价,并按照评价系数的大小对各处理排序。结果表明,较对照处理,郑州黄黏土(YC)、洛阳粉质黏壤土(SCL)和驻马店重壤土(HL)中循环曝气滴灌处理均可以改善盆栽草莓的种植效果,提高草莓种植的综合效益,而由于土壤质地不同的影响以及循环曝气处理需要增加水电费、人工费等资金的投入,南阳黏壤土(CL)中曝气处理的综合效益稍低于对照处理;循环曝气滴灌处理条件下,YC中草莓种植的综合效益最高,其次为CL和HL,最低的是SCL。
The research select the cost of irrigation water, electricity bills, labor cost, test cycles, single fruit weight, fruit total sugar, vitamin C content and root condition as evaluation index, making use of the comprehensive evaluation method that combined the subjective weighting method and the entropy information method to evaluate the comprehensive benefit of aerated drip irrigation on potted strawberry under different soil condition. The results showed that compared with control treatments, aerated drip irrigation could significantly improve the growth and comprehensive benefit of strawberry in the Zhengzhou yellow clay （YC）, Luoyang silty clay loam （SCL） and Zhumadian heavy loam （HL） treatment, but the comprehensive benefit in the Nanyang sticky loam （CL） treatment decreased due to the difference of soil condition and the investment of electricity, labor cost increased. In the aerated groups, the comprehensive benefit in the YC treatment was the best, followed by the CL and HL treatment, the SCL treatment was the lowest.
