| Abstract: | Using the best mixed plan,the experiment oi 11 treatments show that the highest plot outputs of 1998,1999 and 2000 reach 12.92t/hm2,13.815t/hm2 and 15.018t/hm2 respectively.343 plans are obtained through computer design,the best combination plan with yield of 15 ~ 17.625t/hm2 is to use 60t/hm2 of organic manure,462 ~ 483kg/hm2 of N,to irrigate 600t/hm2 of water before seeding,1377~ 1458t/hm2 of water in crop growth,to maintain the density of potato and sorghum with 72705-83415 plant/hm2 and 65205-75915 plant/hm2 respectively. |
