玉米机械化播种常用的有外槽轮窝眼式、转仓式、气吸式和气吹式播种机。外槽轮窝眼式排种机易堵塞,出苗后还需要耗费大量的人力间苗、定苗和补苗,比较麻烦;气吸式、气吹式播种机播种精确度较高,种子投放准确,又不伤种,但对播种机的精度要求较高,机具价格昂贵,播种费用也较高,农户接受有难度。转仓式播种机属单粒精量播种机,玉米行距、株距均可调,调整也很方便,并且能一次性完成施肥、播种。价位也比较适中(2行播种机销售价一般不超过2000元/台,3行播种机2000多元/台,4、5行均有销售),机具性能稳定,播种后无需间苗、定苗或补苗,不伤种子,比较受农民欢迎。
Maize mechanized seeding commonly used Outer groove wheel socket, rotary warehouse, air suction and air blow planter. Outer socket wheel eye socket seeder is easy to plug, post-emergence also need to spend a lot of manpower Miao, Dingmiao and Miao Miao, more trouble; air suction, air blow seeder sowing precision, seed delivery accuracy, nor Injury, but the precision of the planter higher requirements, equipment expensive, planting costs are higher, farmers accept difficult. Rotary warehouse planter is a single precision sowing machine, corn row spacing, spacing are adjustable, adjustment is also very convenient, and can be a one-time completion of fertilization, sowing. The price is relatively modest (2 rows of seeder sales price is generally not more than 2,000 yuan / Taiwan, 3 rows of planter more than 2000 yuan / Taiwan, 4,5 firms have sales), machine performance and stability after sowing without Shimiao, Dingmiao or Miaofei, Do not hurt the seeds, more welcomed by farmers.
