北方夏玉米免耕覆盖播种技术及配套机具的研究

Summer Maize Planting Techniques and Necessary Machines for Non Tillage Mulching

根据我国北方小麦玉米两熟种植制度，夏玉米采用免耕覆盖播种的农艺要求，分析研究了配套机具的田间工作性能，并研制出了两种用在免耕覆盖播种机上的新型开沟器，经田间对比试验表明，两种新型开沟器能满足农艺要求，并具有侧深位施种肥的特点。

Based on the technological features of summer maize non tillage planting techniques in the double cropping system of wheat and maize in north part of China, this paper has comprehensivelyanalyzed the field working features of the perfection machines,and has developed 2 kinds of furrow openers for summer maize non tillage mulching planting. Field control experiments show that the openers can meet the agronomical requirements and have the advantages in seed sowing and fertilizer application at deep side position of furrows. Thus could provide a basis for the further development of the perfection machines.
