Studies on a Track Type Tea Field Working Machine (III)

A Fertilizer Applicator and A Cultivating Machine

Abstract

According to the experimental results obtained before, a fertilizer applicator and cultivating machine were constructed for the experiment. The chassis used here was reported previously in the Ist report. A fertilizer applicator and a cultivating machins consist of two ridge type and the horse power of the engine that can produce 8.3kW (12PS) is enogh to do it because a stretch of row spacing in young tea field can be cultivated by traveling twice and a stretch of row spacing in medium and mature tea field is cultivated by traveling once. The complex fertilizer containing organic matter was used as an experimentai fertilizer and in this case a fertilizer applicator was superior to manual fertilization in uniformity of distributed fertilizer. And the difference between the amount, of actual fertilizer distribution and the amount of designed one was Less than 10% of the designed value. The fertilizer distributing and cultivating area per hour was 25.3-30a/h.
