摘    要:东北半干旱区是我国北方旱农地区的重要组成部分,多数地区没有灌溉水源。从气候条件来看,由于本区降水量少,年变化和季节变化大,春季多大风,蒸发强烈,春旱十分严重,已成为制约本区农业生产的主要因素。本研究针对本区的资源环境和灾害特点等,选取了坐水播种和苗期补灌技术,并进行了盆栽试验研究,提出了坐水、补水条件下的产量最佳供水模式,旨在探索适合于东北半干旱区的农业抗旱节水技术集成模式。

关 键 词:东北半干旱区  坐水播种  苗期补灌  大豆  产量  供水模式

Abstract:Northeast semi-arid region is one of the main parts of the north dry farming area,most of which have no irrigation water resources.Due to the less rainfall and it's big annual and interannual variability,the windy spring and the high evaporation rate,the drought disaster is seriously in spring,which has become a main factor limits the agriculture production of the region.Anti-drought and water-saving technological assembling pattern which is suitable to northeast semi-arid region,according to the characteristics of the resources,environment and the natural disaster to agriculture,the technologies of bed-irrigation and seedling stage mending irrigation are selected.Based on the experiment in pot,the best water supplying pattern is proposed in the paper.
Keywords:Northeast semi-arid region  bed-irrigating  seedling stage mending irrigation  soybean  yield  water supplying pattern
