小麦等深撒播机的设计与试验

小麦撒播栽培技术抗旱性好,能够起到一定的防冻害的作用,并有利于小麦增产,但缺少相应机具。针对此问题研制的小麦等深撒播机可实现小麦撒播机械化作业,机具与拖拉机配套,一次进地可以完成施肥、旋耕、等深撒播、起埂和镇压等全部作业。用该机具播种,出苗整齐,苗群分布均匀,苗期株间竞争小,个体壮实,可实现大群体与壮个体的统一,同时具有减少田间蒸发及提高麦苗抵御冬春冻、旱灾害能力的多重效应,达到增产增收的目的。

Design and Experiment of the Wheat Even Depth Broadcast Sower

Wheat broadcasting technique has advantage of drought resistance,and also it can play a certain role in anti-freezing,and contributing to yield increased,but at moment limited by the lack of appropriate equipment.Aiming to resolve this problem,developing wheat and other crops deep broadcasting sower can realize the wheat mechanical drilling.Agricultural equipment can combine with tractors finish fertilizer spreading,rotary cultivation,wheat broadcasting,and ridge forming and pressing in one time.with this planting equipment,emergence uniformity,seedling group distribution evenly,seedling competition is small,individuals plants are sturdy,can achieve unified between large groups and the strong unity of the individual;also reduce the field evaporation,improve winter wheat seedlings to resist cold,drought disasters of the multiple effects,to increase production.
