针对巨菌草人工种植劳动强度大、工序繁琐、预切种式巨菌草种植机械设备缺乏以及种苗个体直径差异较大等问题，研制了一种2 CJ Q-1型预切种式巨菌草种植机，进行了推种机构、排种装置和牵引连接机构等关键部件设计，确定了其关键参数，该机能一次实现松土开沟、基肥深施、单行排种、覆土埋种和镇压等功能.田间试验表明：在拖拉机前行速度为2.88~3.6 km/h、后动力输出轴转速为2240~2970 r/min时，漏播率为2.27%，重播率为3.209%，发芽率大于80%，种植作业效果良好，主要性能指标基本满足巨菌草种植农艺要求.

According to the fact that artificial planting is a high labor intensity and tedious work,the lack of precut type plant machinery and individual differences of seedlings diameter.A 2CJQ-1 precuting type Pennisetum.sp planter was developed.The ditching,deep fertilization,seeding,earth covering and pressing can be finished in one time.Several critical components such as pushing seeds mechanism,traction connecting mechanism and seed-metering device were designed.Field experiments show that the planter leakage rate was 2.27%,repeat seed rate was 3.209% and germination rate was greater than 80% when traction speed is 2.88 ~ 3.6 km/h and output shaft speed is 2 240~2 970 r/min.Operation effect is good, the main performance indicators conformed with Pennisetum.sp planting agronomic requirement.
