“中耕深施化肥器”是西坪山大队经过50多次试验研制成功的一种小型半机械化农具,造价低廉,使用方便,适合大面积中耕,除草。同时,能自动把化肥施入离玉米3—4寸远的土壤内,还能给作物培起4寸多高的活土层。化肥入地后,被埋得严严实实,肥效一点也不流失。在作物苗期和生长期都可使用。过去,西坪山大队每到夏季中耕、除草、追肥时,常常是忙的顾此失彼。一亩玉米光中耕、除草、追肥,平均每道工序就要用1个多工。而使用“中耕深施化肥器”,中耕、除草、
“Sowing deep fertilizer facilities” is a small semi-mechanized farm implements successfully developed by Xipishan Brigade more than 50 times, which is cheap, easy to use and suitable for large-scale cultivation and weeding.
