我国西北干旱地区耕作高效综合利用技术分析

我国西北干旱地区是西部地区的重要组成部分,在国家实施西部大开发的进程中,如何保证农民的吃饭问题,已成为人们关心的头等大事。在目前解决吃饭问题仍然要依靠农业生产,农业是世界上最原始、最古老和最根本的产业,随着人口的不断增长和自然环境的不断枯竭恶化,农业可持续发展已成为当今世界各国在其农业和农村经济发展乃至整个国民经济发展过程中的核心内容。在西北干旱地区实施有效的耕作技术,对改变坡面微地貌、减少土壤侵蚀、增加土壤抗性、蓄水、保土性能、培肥地力和提高作物产量均有显著作用。在上述背景下,分析了地膜覆盖、节水灌溉、保护性耕作和间套四种效果较好的耕作高效综合利用技术,可供决策部门在制订农业发展计划时参考。

Analysis of Efficient Farming Technique in Arid Area of West China

The northwest arid area is an important part of China west region,in the process of west development,the problem of grain has become the priority one,which relies on agriculture.Agriculture is the most primitive,ancient and basic industry,with the increase of population and the worsen of natural environment,the agriculture sustainable development is becoming the core in agricultural development of the world and national economy.In west area,the efficient farming technique can change slope landforms,reduce soil erosion,increase the ability of soil conservation,improve soil fertility and increase crop yield.Four kinds of farming techniques such as film cover,water-saving irrigation,protective farming and intercropping are analyzed,which provide references in working out agricultural plan for departments of decision-making.
