Abstract:: Technology of solid -seeded soybean is a new culture technology imported from American , and canincrease y ield of soy bean .This technology has been assimilated and improved , and there has formed threeculture pat terns that is solid -seeded wi th w ide row , solid -seeded with narrow row and solid -seeded w othlevel culture .These technologies have been developed with different ecology factors and dif ferent productiveforce levels , and can increase yield of soybean by more than 20 %.Soy bean area used these technologies has beeng row n to 670 thousend hectares and has achieved remarkable econcmic benef it .The technology of solid -seeded soy bean make the row space narrow , the plant space wide and thedistribution of plant more reasonable , w hich increasegreen area and improve factors of illumination , especiallytthe factors in middle and low er levels .All these are the physiological baes of increasing yield .The key of this technology is semi -short variety , deeply loosened soil and application of fertilizers,herbicides and sintable machines
