1974年我们试制成功了鼠洞犁。经过试验改进,1978年已投入大面积推广使用,全局投入二十台机具,一万一千亩旱杂作物田有九千多亩打了鼠洞,二万三千亩棉田有一万五千亩打了鼠洞。鼠洞犁主要用来在地下打鼠洞,适用于湖区平原旱田作物降低地下水位,或作物抗旱进行暗灌,能保持土壤表面松软,有利作物根系生长。还可用于铺放地下电缆和地下电话线路。机具主要由一根横梁、一把犁刀、一个塑孔器(炮弹头)和悬挂架构成(见图)。该机同东方红—54/75 In 1974, we trial-produced mouse-hole plow. After the test improvement, 1978 has invested a large area to promote the use of the global investment in 20 sets of equipment, 11,000 acres of dry crop fields have hit more than 9,000 acres of rat holes, 23,000 acres of cotton fields have 15,000 Mu hit a rat hole. Mouse hole plow is mainly used to hit rat holes in the ground, suitable for dry land crops in the lake plain to reduce the water table, or crop irrigation for irrigation, to keep the soil surface soft, favorable crop root growth. Can also be used for laying underground cables and underground telephone lines. The machine is mainly composed of a beam, a coulter, a metronome (bullet head) and a hanger (see picture).
