Experimental study on sowing seeds by air‐stream metering mechanism

摘要

In china,grassland has many serious problems, such as degeneration,desertification and salinization and so on.S.J.Miles et al (1999) have studied a lightweight dibber drill, which can be capable of precisely metering small doses of granular pesticide with each seed.Tai Shuyun et al (2003) have designed an incline outer‐fluted feed with upper distribution which can satisfy the planting demands of wheat precise seeding.At present, due to many merits, the outer groove‐wheel metering mechanism are still inclined to sowing herbage and the crops in china.But, it had some disadvantages.This article proposed a new air‐steam metering mechanism.
