Abstract:
To set up integrated cultivation technique for high-oil soybean，the individual technique including screening of drought tolerance or resistance soybean cultivars，effects of soil moisture on yield and oil content of high-oil soybean，tillage technique of reserving soil moisture，effect of covering plastic film between rows on yield of soybean，and the combination of these single technique were researched.The results were as follows：Eight drought tolerant or resistant high-oil soybean varieties Heinong 37，Heinong 41，Heinong 44，Hefeng 40，Kenong 4，Hongfeng 11，Heihe 27 and Hefeng 47 were screened，which were fit to plant in main production region in Heilongjiang.The yield and oil content of Heinong 41 could be affected negatively by drought stress at any growth stage.The degree affected by drought were podding-seedling＞seedling ＞podding ＞blooming＞seedling，and drought stress occurred at podding-seedling stage caused 27.1% yield loss of single plant and 12.6% oil content loss in Heinong 41.The plowing and ridging in autumn tillage technique was better in reserving soil moisture than that in spring，and the technique made yield increased from 14.28% to 16.67%.；The optimizing planting density of Heinong 44 was either 2.0-2.5×105plants hm-2 on hole-planting or 2.5×105 plants hm-2on double strip planting；The covering plastic film between rows could increase soybean yield and worth extending in suitable soybean production region.Yield increasing ranged from 13.55% to 25.4%；The elite model of cultivation technique in arid area for both good-quality and high-yield was set up，namely，high oil content soybean cultivar Heinong 44 was used as core technique，integrating techniques including hole-planting，optimizing fertilizing (N7+P14+K10)，using seed coating agent for drought tolerance，using leaf fertilizer for drought tolerance，and covering film between rows under the condition of plowing and ridging in autumn.
