Influence of Supplementary Water Supply Patten-Survey on Soybean Growers in Semi-arid China Northeast Region
Northeast semi-arid region is one of the main parts of the north dry farming area, most of which no irrigation water resources. There is less rainfall with un-uniform distribution, more windy weather in spring and intensive evaporation in the region, spring drought is a main factor to limit the agricultural production of the region, To get anti-drought and water-saving technologies assembling pattern which is suitable to the 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 were selected. Based on the experiment in pot which was conducted in 2004 in Gannan county of Heilongjiang province, the experiment base of national “863project, the influences of different water supply condition on soybeans growing and water use efficiency (WUE) were studied,the water supplying pattern under the condition of highest WUE was proposed in the paper.
