正文 第十八章 第一个曲辕犁的诞生!(第2页/共3页)

“将军,此犁小巧,又只使一人一牛,自然不如二牛负直犁。方才犁过,地上犁痕深浅一致,一牛负犁,速度自然不如二牛负犁,吃土不够深也是因为犁具太小,若是再大一些,吃土定比直辕犁更深更快。”

军匠开口解释,赵泗豁然开朗。

这次做出来的曲辕犁只有直辕犁的一半大小,因为赵泗是跟着自己脑海里的记忆中来的。

时代和时代不一样。

秦朝时期,哪怕是直辕犁都是奢侈品,普通百姓还在使用耒耜的传统耕种作业模式。

汉朝以后,长直辕犁才逐渐普及开来。

直至唐初,长曲辕犁才真正面世。

至此,长直辕犁才被完全淘汰。

相同大小的情况下,曲辕犁性能完全碾压直辕犁,这完全是结构和力学上的进步。

而赵泗所画的小巧便携的曲辕犁,则在宋朝时期才普遍推广开来。

短曲辕犁的推广普及很大程度上得益于南方地区的日渐开发。

长曲辕犁更适宜大规模耕种,面积大,地势不复杂的情况下,大犁耕种效率优于小犁。

而普遍面积小,地势情况复杂的南方地区,则更加适合使用短曲辕犁。

尔后乃至于明清时期,人口进一步增多,粮食生产中心由北向南过度,人均土地不断减少,普通百姓人均数亩耕地成为了常态,小而精的短曲辕犁就更加符合社会要求。

但是,长曲辕犁从未消失,因为本质上大家都是曲辕犁,大小不同并没有真正的革新改变,只是使用长曲辕犁的大多是地主士绅阶级,而非贫农阶级。

而秦朝时期。

自耕农一户授田大多为百亩上下,产量中心也集中在中原这般地势平稳,地貌并不复杂的地区,故而长曲辕犁比短曲辕犁更加适合推广使用。

有军匠解惑,赵泗也不用动脑子思索,王离当场下令再做一个长曲辕犁出来。

日上中天,到了中午饭的时候。

可惜赵泗人在军营,食物配给是一日两餐,饿倒不是很饿,可是晌午不吃点东西总感觉有些不舒服。

趁着空隙,王离和赵泗继续闲聊。

赵泗乐得交好对方,又得益于赵泗的金手指,王离和赵泗的交谈体验也十分愉快。

赵泗眼看唠的差不多,也开口询问对方的姓名。

“我名王离。”王离开口说 『加入书签,方便阅读』
