玉米精量施水播种机的研制

Development of a Precision Maize Planter with Water Disperser

研制了一种适合在干旱和半干旱地区种植玉米,又能同时施水、施肥的小型播种机。该机的特点是可以根据土壤墒情和农业技术要求,调节每穴施水量、施肥量和播种量;种子和肥料分开,避免了肥料烧苗;开沟器开出的种沟具有鼠道特征,实现了自动覆土,防止了土壤水分的蒸发。

A mini-type maize planter which is suitable to be used in arid and semiarid area with irrigating and fertilizing at the same time is developed. The machine possesses the characteristics: the seeds, water and fertilizer per hole can be adjusted according to agricultural requirement; seeds and fertilizer are separated avoiding the seedlings burnt by fertilizer; the seed ditch which is formed by the drill opener of the machine is similar to a mouse hole. The soil moved to the formerly position by gravity and the seeds is covered and the moisture is held in the soil.
