黑龙江省玉米膜下滴灌技术推广成效及趋势分析

Popularization Effect and Trend Analysis of Corn Membrane Drip Irrigation Technology in Heilongjiang Province

经过3～4年生产和科研实践证明,玉米膜下滴灌技术适合黑龙江省西部干旱地区的第一至第三积温带应用推广。从宏观效益、比较效益、节水增产及投入产出等方面分析其推广成效,得出玉米膜下滴灌生产模式更适应规模化、集约化程度高的种田大户经营的结论。并从膜料、滴灌材料及配套农机具等方面的研发及改进分析了其趋势,以期为膜下滴灌技术的推广提供参考。

Through 3-4 years production and the scientific research practice,the corn membrane drip irrigation technology suits to promotion in the arid area of the first to third product temperate zone in west of Heilongjiang Province. Popularization effect was analyzed from the macroscopic benefit, comparison benefit, water saving and production increase, and input-output ,as the result, the corn membrane drip irrigation production pattern adapts the farmers of formalization and high intensified degree. The trendency was analyzed from the membrane material ,the drip irrigation material, the necessary agricultural tools,machinery ere, so as to provide references for the promotion of membrane drip irrigation technology.
