畜力是我國農業生產中重要的动力,為了能了解東北地區耕馬牽引力的情况,于1956年9月间,在本院东陵實驗農場,由畜牧教研組的同志代為選擇了耕馬三匹,這三匹馬都是東北農村中常用的馬种,惟健康情况較一般農業生產合作社飼養的为强。試驗是在東陵农場的耙后地上進行,地勢完全平坦,試驗方法是在瓏長二百米的田塊上,每馬每次分別牽引石滾,一组環形鎮壓器、十六片畜力圓盤耙、十六片畜力圆盤耙加砂包和无負荷空行等处理。每次均测定彈簧拉力表上所示的牽引力,二百米長行走所
Animal power is an important driving force in China’s agricultural production. In order to understand the situation of traction in northeast China, in September 1956, at the Dongling Experimental Farm in our hospital, the comrades of the Animal Husbandry Teaching and Research Group chose to have three horses for farming. All three horses are common horses in northeastern rural areas, but their health is stronger than that of the general agricultural cooperatives. The test was carried out on the raking ground in Dongling Farm and the terrain was completely flat. The test was carried out on the plots of 200 meters long and one horse at a time, each with a series of annular crushers, Disc harrows, 16 disc harrows plus sand packs and no-load blank lines and other treatment. Each measured spring tension shown on the traction, two hundred meters long walk
