基于部分预算法下加气灌溉技术经济效益分析

Economic Benefit Analysis of Aerated Irrigation Technology Based on Partial Budget Method

加气灌溉是目前最为高效的节水灌溉技术之一,是在地下滴灌的基础上,利用空气泵或气泡发射器提高土壤含氧量的一种灌溉方法。为了明确加气灌溉技术在大田作物种植中的主要应用效果与经济效益,为加气灌溉技术在农业生产中的推广及应用提供理论依据,采用部分预算法对田间加气灌溉后的经济效益进行综合评价。研究结果表明:与常规滴灌技术相比,加气灌溉技术与常规种植技术相比,总收益分别为25400.05元/hm^(2)和20162.14元/hm^(2);从农业净收益来看,加气灌溉技术可以增加326.03元/hm^(2),部分投资收益率超过700%;加气灌溉技术可以显著减少农业灌溉用水量,提高作物产量,提升农业经济收益,具有良好的应用推广价值。

Aerated irrigation is one of the most efficient water-saving irrigation technologies,which is a light method to improve soil oxygen content by using air pumps or bubble emitters on the basis of underground drip irrigation.In order to clarify the main application effects and economic benefits of aerated irrigation technology in field crop cultivation,and to provide a theoretical basis for the promotion and application of aerated irrigation technology in agricultural production,this study uses partial and algorithmic comprehensive evaluation of the economic benefits after aerated irrigation in the field.The results of the study show that compared with conventional drip irrigation technology from,the total return of aerated irrigation technology compared with conventional planting technology is 25400.05yuan/hm^(2) and 20162.14yuan/hm^(2),respectively.In terms of net agricultural return,aerated irrigation technology can increase 326.03yuan/hm^(2),and the partial return on investment is more than 700%.The research results show that aerated irrigation technology can significantly reduce agricultural irrigation water consumption,improve crop yield and enhance agricultural economic returns,and has good application and promotion value.
