Abstract:

Result s of the ex periments from1997 -1999 reveal that :Serious falling is a obstacle that yield is increasedon semidw arf soy bean variety Heihe 19 .Compared w ith Lo ng 3 cultivation earlier stage of its bearing , allcombinations about row spacing and density , soybean stalks are no t falling , the way of Heihe 19 is growing well ,leaf area is increased , light is distributed w ell , the rat that light energy is utilized is increased , nit rogen -fixingablitity of colony and absobing abili ty of root are st reng then , but low densi ty combinat ions are not clear .Laterstage of its bearing , falling become serious , falling s of the combinations about wide row spacing and hig h densitybecome more serious , its yield are reduced , the colonies of low density combinat ions are growing well , but it s yieldincreased are not clear , other combinations yield increased are bigger , it s range is 7 .9 -19 .7under this circumstance, same row spacing , high density is bet ter than low , same density , narrow row spacing is bet ter than w ide ,the solid seeding that row spacing is 15 cm and densi ty is 667000 plant/hm2is best in the ex periments .
