摘 要:An optimal cultivation technique mathematics model of naked barley in Diqing has been studied in the *** experiments with a regression analysis method for three unknown factors were conducted to study the naked barley yield’s *** results showed the optimal cultivation technique mathematics model is y=2780.20 + 71.45 X+ 82.12 X-77.71 X+70.05 X-135.80 X- 149.96 XX-218.21 X X in *** naked barley yield would attain above 2780 kg/hm by the mathematices model when the seedling were recommended between 84.33×10/hm to 104.31 ×10/hm,the nitrongen with applied amount between 183.38 kg/hm to 204.51 kg/ hm and PO with applied amount between 25.64 kg/hm to 27.69 kg/hm were recommended in *** model was applied to cultivate naked barley in 2004- 2006,the yield of naked barley were increased more 600 kg/hm than CK and the economical Benefit was noTable in Yunnan Tibet prefecture.
