摘　　要：根据最优设计原理,采用最优混合设计组合成11个处理试验研究表明,1998年小区最高产量为12.92t/hm^2,1999年小区最高产量达13~815t/hm^2,2000年小区最高产量达15.018t/hm^2。由计算机计算筛选出343个方案,其中15～17.625t/hm^2产量的最优组合方案为施有机肥60t/hm^2,追肥施N素462～483kg/hm^2,播前浇底墒水600t/hm^2,补灌1377～1458t/hm^2,马铃薯套种高粱种植密度为马铃薯7.2705～8.3415万株/hm^2,高粱6.5205～7.5915万株/hm^2。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.
