条播条灌机 中国农业大学(东校区)研制的2BS/12-Ⅱ型和2BSF-9-Ⅱ型条播条灌机,适用于干旱地区的精播、施肥和灌水,可一次完成开沟、施肥、播种、覆土和灌水作业。该机采用箭铲鼠道式开沟器,阻力小,入土性能好,不翻乱土层,湿土或底土直接覆盖种子,促进种子早发芽早出苗;采用盘式精密排种器,通过改变孔盘的型孔大小来改变播量,既能进行播量45～90公斤/小时平方米的精播,又能进行播量105～270公斤/小时平方米的点条播。灌水部分采用拖拉机背负两个容积为0.36立方米的贮水箱方式。灌水量0～1800公斤/小时平方米可调。灌水采用地下暗灌方 Drilling machine: 2BS/12-II and 2BSF-9-II bar-stem barrow machines developed by China Agricultural University (East Campus) are suitable for fine-seeding, fertilization and irrigation in arid regions. , sowing, earth covering and irrigation operations. The machine adopts arrow spade type opener, low resistance, good earthing performance, no overturning soil layer, wet soil or substratum directly covering seeds, promoting early germination of seeds as early as possible; using disc precision metering device, by changing The hole size of the hole plate is used to change the sowing volume, which can not only perform precision sowing of 45-90 kilograms per hour square meter, but also perform spot sowing of 105-270 kilograms per hour square meter. The irrigation section uses a tractor carrying two tanks with a capacity of 0.36 cubic meters. Irrigation volume 0 ~ 1800 kg / hour square adjustable. Irrigation using underground irrigation
