半干旱区坡耕地大豆抗旱保水技术集成模式对产量的影响

Effects of Technological Assembling Pattern of Anti-drought and Water-retention on Soybean Yield in Slopping Cultivated Land in Semiarid Region

根据黑龙江省西部半干旱区的资源、环境及灾害特点,选取了坐水播种和苗期补灌2种抗旱节水技术和垄向区田保水技术,在甘南县国家863试验基地研究了该3项技术集成的增产效应,从增产角度提出了适合于黑龙江省西部半干旱区坡耕地的抗旱保水技术集成模式。

According to the characteristics of the resources, environment and the natural disaster to agriculture in the west part of Heilongjiang province, two anti-draught and water-saving technologies, bed-irrigation and seedling stage mending irrigation, and one kind of soil and water conservation technology, ridge plotted field, were selected to study the yield increasing effect of the 3 technologies assembling in Gan＇nan county, the national 863 project experimental base. From the view of yield increasing, a suitable technological assembling pattern of anti-drought and water-retention for soybean in slopping cultivated land in semiarid region in the west part of Heilongjiang province were proposed. And based on the analysis of the benefit of soybean, the necessity of the 3 technologies assembling in the region was illustrated in the paper.
