陇右梯田因地势较高，灌溉不便，肥水亦无法顾及xiaomao8◇cc且又是刚刚开辟，野地未得驯化xiaomao8◇cc羌人耕种，亦是新手xiaomao8◇cc能有多少亩产，刘备实无法估计xiaomao8◇cc
首批开镰的麦田，统计后上报xiaomao8◇cc足有三石新麦xiaomao8◇cc
消息传来，刘备及幕府属吏，皆松了口气xiaomao8◇cc以每户五十亩计，可得新麦百五十石xiaomao8◇cc可活壮劳力五人xiaomao8◇cc以一家老小计，足可养活二十五口xiaomao8◇cc
羌人行“饶妻制”xiaomao8◇cc家中人口众多xiaomao8◇cc然通常亦不过十余口xiaomao8◇cc二十五口之家，亦是诸如豪帅一类的羌人大户xiaomao8◇cc若能亩产三石，陇右从此得安xiaomao8◇cc
且，今年只是初种xiaomao8◇cc农时、节气，天时、地利，皆未竭尽所能xiaomao8◇cc来年精工细作，再行代田法，“一岁之收，常过缦田亩一斛，善者倍之”xiaomao8◇cc“缦田，谓不为甽者也xiaomao8◇cc”即不开沟，不分行，将谷种散播在田中，产量很低xiaomao8◇cc陇右先前多采用此种耕作方法xiaomao8◇cc
换言之，代田法，每亩均产，能提高一石xiaomao8◇cc
待陂渠修到田间地头，坂上溪水能尽灌溉之力xiaomao8◇cc若无坂上溪水，亦可层层架设龙骨翻车，引谷中溪水上坡xiaomao8◇cc想必产量亦会增加xiaomao8◇cc若也能提高一石xiaomao8◇cc两项相加，足可增产二石xiaomao8◇cc陇右梯田若能达均产五石xiaomao8◇cc则万事备矣xiaomao8◇cc
种田十倍利，经商百倍利xiaomao8◇cc
就时下而言，刘备不希望有完全脱离土地的商人或是仕人出现xiaomao8◇cc民以食为天xiaomao8◇cc对于封建时代而言，土地的重要性，不言而喻xiaomao8◇cc然，土地的价值，也必将被刘备潜移默化的稀释xiaomao8◇cc
户户有良田一顷xiaomao8◇cc维系一家丰衣足食xiaomao8◇cc农作机关器，及畜力的普及，最大程度的解放生产力xiaomao8◇cc种田家中老农即可xiaomao8◇cc大量的壮劳力，往来丝路，僦车西行，赚取百倍利益xiaomao
