    摘要:

    針對東北壟作區(qū)春季玉米免耕播種時施肥量大,正位垂直施肥易燒種,側位施肥易堵塞的問題,研究設計了一種并列組合式種肥分施防堵裝置。在玉米碎稈覆蓋地試驗結果顯示,該裝置土壤擾動量為17.8%,播種平均深度為44mm,施肥平均深度為78mm,種肥水平間距為32mm,垂直間距為34mm,種肥間距合格率達93%,提高了播種質(zhì)量。與正位垂直施肥和前后側位深施肥方式相比,該裝置防堵能力強,種肥分施效果好。

    Abstract:

    In view of the exist those main problems in the area of northeast ridge during the spring corn planting, such as large quantity of fertilizer, seed burned easily by the vertical fertilizing while lateral fertilization easily plugs openers, an undynamic anti-blocking mechanism and a paratactic separate application of fertilizer and seed mechanism were designed. The experiment in the field that covered with broken stalks of corn showed that the soil disturbance was 17.8%, planting depth was 44mm, depth of fertilizer was 78mm. The trial also showed that the level pitch of seed and fertilizer could be 32mm, while the vertical spacing was 34mm, and 93% could meet the requirements of agronomic. Compared to the orthophoric and lateral fertilizer application methods, the planting quality has been upgraded, while the blocking problem existed in the mentioned fertilization was also improved, and the opener could get through the straw more easily now.
