玉米免耕播种深松联合作业机试验研究

研制了一种适用于我国北方一年两熟地区的玉米免耕播种深松联合作业机，一次作业能完成种床秸秆清理、开沟、施肥、播种、覆土、镇压和深松等多道工序，解决了玉米免耕播种和深松单独作业时带来的作业次数多、压实土壤和功率消耗大等问题。试验结果表明，玉米免耕播种与深松联合作业在技术上是可行的。

Experiment and research on drilling and subsoiling combined machine for no-tillae maize

A new drilling and subsoiling combined machine for no-tillage maize, which can be used in two crops a year region of northern China,was developed. It can once complete all field works of pushing aside the stalk, ditching, fertilizing, seeding, covering the soil, squashing the soil and subsoiling, solving some problems such as more tasks, compacting the soil, increment of power consumption when seeding and subsoiling are completed separately. The testing results show that the operation of drilling and subsoiling combine is feasible on technique.
