打穴播种机研究的发展与现状

在现代农业种植业生产中，为了改良土壤和提高土壤肥力，种植工艺不断更少，少耕，免耕，地面覆盖和秸秆还田等措施正在推广，对农业种植机械的适应性提出了新的要求，本文在分析打穴播种工艺特点的基础上，阐述了打穴播种机研究的发展并分析了各种机具有的特点及其存在的问题，提出了打穴播种机研究工作的重点和需要解决的问题。

DEVELOPMENT AND STATUS OF RESEARCH ON PUNCH PLANTER

In order to improve soil condition for plant growth and to increase soil productivity many cultivation methods such as minimum tillage, no tillage and soil cover with plastic films and agricultural waste materials (plant residues) were introduced into crop cultivation system in modern agricultural crops production. Under such soil conditions the conventional planting machinery with soil furrow opening can not operate perfectly because of plugging of soil opening parts. On the basis of analyzing the working principle of punch planting the paper presents the current development and progresses of studies on the punch planter and the characteristics of different punch planting technology. The existent problems and emphases on design for punch planter are pointed out for the further research.
