据测定,地表撒施碳铵,其肥效利用率只有25～30%,而合理深施,肥效可提高一倍。为了解决深施碳铵的问题,安徽省农机所研制了2FB-0.4型施肥播种机,并于去年8月通过了省级鉴定。特点与用途 1.经济效益高。地表撒施碳铵,每亩需40斤左右;深施碳铵,每亩只需20斤,可节省2.6元。 2.性能可靠。该机采用搅拌和强制相结合排肥,较好地解决了碳铵流动性差、易架空、堵塞和粘附的问题。使用可靠性系数达99.2%,即使碳铵含水率高达12%时也能正常作业,且施得均匀。 3.工效高。人工打眼穴施化肥,每人每天只能施肥0.2亩。而用一头牲畜或两个人牵引该机施肥,每
It is determined that the surface of the application of ammonium bicarbonate, fertilizer efficiency utilization rate of only 25 to 30%, while reasonable depth, fertilizer efficiency can be doubled. In order to solve the problem of deep application of ammonium bicarbonate, Anhui Agricultural Machinery Institute developed a 2FB-0.4 fertilizer seeder and passed the provincial appraisal in August last year. Features and Uses 1. High economic efficiency. Ammonium bicarbonate applied to the surface, about 40 pounds per acre need; deep-applied ammonium bicarbonate, only 20 pounds per acre, can save 2.6 yuan. 2. Reliable performance. The machine uses mixing and compulsive combination of fertilizer, a better solution to the ammonium bicarbonate poor mobility, easy overhead, plugging and adhesion problems. Using a reliability factor of 99.2%, even with ammonium bicarbonate moisture up to 12%, it can work normally and be uniform. 3. High efficiency. Apply artificial fertilizers point hole, only 0.2 mu per person per day fertilization. And with a livestock or two people traction machine fertilization, each
