文摘:研究表明，浙江省雙季稻區稻水象甲二代蟲量低的首要原因是絕大部分一代成蟲遷出早稻田夏蟄並越冬，構成二代蟲源的比例極微。 -
The testing results of straw cutting and field experiment show that this mechanism has excellent anti - blocking capability. ( 2 ) a new no - till planter equipped with the strip chopping anti - blocking mechanism was developed. compared with other no - till planters, it possesses higher anti - blocking capability and suits the need of seeding in huabei plain where the winter wheat - summer corn continuous double cropping system gives much straw and short planting season
（ 2 ）研製出新一代玉米免耕播種機，配以新型防堵機構，防堵性能優越，連續三年分別對三代樣機進行的田間試驗表明，可在地表整稈覆蓋量10t / ha的條件下連續作業而不堵塞，該播種機的防堵性能好。 -
