摘要:  根据最优设计原理,采用最优混合设计组合成l1个处理试验研究表明,1998年小区最高产量为12.92t/hm2.1999年小区最高产量达13.815t/hm2,2000年小区最高产量达15.018t/hm2。由计算机计算筛选出343个方案,其中15~17.625t/hm2产量的最优组合方案为施有机肥60t/hm2,追肥施N 素462~483kg/hm2,播前浇底墒水600t/hm2,补灌1377~1458t/hm2,马铃薯套种高粱种植密度为马铃薯7.2705~8.3415万株/hm2,高粱6.5205~7.5915万株/hm2。

Abstract:  Using the best mixed plan,the experiment of 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.
