RESEARCH AND DESIGN OF THE SEEDING APPARATUS OF COTTON AND MAIZE PRECISION SEEDER

摘要

Precision seeder is an important object which is being researched, improved, developed and popularized in recent years in the world. But in China, it is just in a development stage. Precision seeding is a modern, complicated and comprehensive technical measure. Precision seeder is the core and critical equipment of the precision seeding technique. However, the precision drop is the core and critical part of a precision seeder. This paper dicusses the working principle and structure design of the precision seeder of middle and small sizes as well as its drop of cotton or maize seed. The experimental results in both laboratory and cultivated land are given analyzed.
