赤峰市玉米膜下滴灌技术推广模式及投资分析

基于赤峰市玉米膜下滴灌工程试验、推广资料及其工程投资情况,以赤峰市常种作物玉米为研究对象,采用试验与数据分析的方法,分析了赤峰市玉米膜下滴灌节水、增产及其投入成本,总结赤峰市玉米膜下滴灌工程技术及栽培模式。结果表明,赤峰市玉米膜下滴灌工程通过分水调压和辅管轮灌,亩均投资降低114元,亩均节水110~140 m3、亩均增产230~260 kg,单方水粮食(玉米)生产能力由原来的2.9~4.1 kg/m3提高到10.33~13.9 kg/m3,可为同类地区推广玉米膜下滴灌工程提供借鉴。

Popularization mode and investment analysis of mulched drip-irrigation technology for corn in Chifeng

Based on the trial， popularization data and project investment of the project of mulched drip-irrigation for corn in Chifeng， the water saving and yield increment from the mulched drip-irrigation for corn in Chifeng and its input cost are analyzed with trial and data analysis by taking the normal crop-corn therein as the study object， and then the technical and planting modes of the mulched drip-irrigation project in Chifeng are summarized herein. The result shows that through water division for pressure regulation and additional pipe for rotational irrigation， the investment per mu is decreased by RMB114 yuan with the yield increment of 230~260 kg per mu for the mulched drip-irrigation project in Chifeng， thus the grain（corn）production capacity per cubic meter of water therein is increased from the original 2.9~4.1 kg/m3 to 10.33~13.9 kg/m3 at present， which can provide some references for the popularizations of the project of mulched drip-irrigation for corn in the similar regions.
