第七十四章 巧夺天工

房俊把桌上的图纸拿给柳老实看，说道：“你来看看这个犁杖，能不能做得出来？”
柳老实闻言，赶紧把自己的双手在裤子上使劲儿蹭了蹭，刚刚他还在家里修补农具，手上沾了不少尘土，又被房俊这一声“师傅”吓得出了不少汗，手黏黏的。更多小说ltxs520.com
蹭得干净了一些，才恭恭敬敬的接过房俊递过来的图纸，细心观看。
“咦？这犁杖的模样有些奇怪啊……犁辕是直的啊，怎么变成弯曲的了？曲辕？曲辕……”
柳老实皱着眉毛看着图纸上这个奇怪的家伙什儿，确定是个犁杖没错，但是很多地方都有所不同。
他是个老木匠了，手艺很是不错，不仅是房家庄子，便是附近几家勋贵的田庄，偶尔也会请他去帮助制作、修补犁杖，这大半辈子制作的犁杖，没有一百也有八十。
图纸上这个玩意他有点看不懂，但是看这画图的线条虽然纤细，但是清晰可辨，明显不会是画错了。
柳老实心里有些发虚，偷偷的瞄了房俊一眼，心想莫非是二郎闲着没事儿，瞎画一个东西消遣自己？
不过应该没这可能啊，人家二郎那是顶顶的贵人，没事儿消遣自己这个和泥巴的臭木匠？
难不成，这个奇形怪状的东西，真的是个犁杖？
柳老实觉得二郎不会无缘无故的消遣自己，便沉下心来仔细看图纸，琢磨着每一个分散开的构件用处是什么。
毕竟是经验丰富的老木匠，这一看，立即看出些端倪。
“曲辕……哎呀！如此以来，岂不是将重心稳稳的固定在这个曲辕的弧顶一点？任凭拉犁的耕牛如何行进，这重心都不会有丝毫偏移，以前为了保证犁杖的重心，使其能够直线前进，使用的是直辕，需要两头耕牛驾着犁杖同时前进才行……犁辕这么由直变曲，岂不是只需一头耕牛便可拉着犁杖耕地？我的老天爷，这设计，简直是巧夺天工哇！”
柳老实大惊失色，立马看出一旦这个图纸上的犁杖能够做出来，会有多么巨大的意义。
最简单的一点，便是能将拉犁杖的两头耕牛变成一头。
这意味着什么？
意味着在同等时间、同等数量耕牛的前提下，耕地速度将会翻一倍！
耕牛的数量极其有限，即便是房家这样的显赫之家，也只有十余头耕牛，土地却有两千多亩。按照以往使用直辕犁来耕地，每年都会有三分之二的土地无法耕完。这些没耕完的土地怎么办呢？很简单，使用人力耕地。
但人力有限，即便所有老幼妇孺全部上阵，也只能耕完总数的三分之一左右。
那么其余的三分之一呢？
因为没时间耕地，便简单的用犁杖勾出一道田垄，随便种些种子了事，可以想见产量会如何。
如果使用这种曲辕犁耕地，岂不是能使用耕牛耕完三分之二的土地？剩下的三分之一再使用人力耕作，就能将所有土地全部耕完！
今年的粮食产量，最少增加一成！
最严重的是，如果天底下全部使用这种曲辕犁呢？
我的老天爷……
柳老实托着图纸的双手不停的颤抖，浑身都打起了摆子，只觉得手中这张图纸简直就是无价之宝，若是一个平民将此物献于朝廷，陛下赏个侯爵怕是也不过分吧？
房俊看着柳老实神情呆滞，身体不停的颤抖，不由得吓了一跳，莫非这老木匠还有中风的毛病？
“噗通”
柳老实屈膝跪在地上，双手将图纸高举过头，颤声说道：“老朽恳求二郎一事！”
房俊莫名其妙，怎么又跪下了？
“快快请起，老柳你这是为何？有何难处，但说无妨。”
