玉米机械化定向播种技术研究进展
Research progress of mechanized oriented seeding technology for corn
摘要
Abstract
Corn oriented seeding is a high-quality and efficient agricultural production mode,which makes the seed surrounded by soil with the posture of upright and tip down,embryo surface parallel to the seeding row or embryo facing up,long axis perpendicular to the seeding row.It can preferentially produce leaves perpendicular to the seeding row,which is conducive to increasing corn yield.In this paper,corn oriented seeding production model and the internal mechanism that this model can promote yield increase were described.Then the working principle,technical characteristics and development trends of corn mechanized oriented seeding technology were expounded based on three aspects:seed posture identification,seed posture adjustment and mechanized oriented seeding.On this basis,combined with the demand of stable area to increase unit yield and total yield under the background of precision agriculture in China,the current research status of corn mechanized oriented seeding technology were summarized,and the reasons for the slow development of the technology were analyzed,and the future research focus,technical bottlenecks to be broken through and development suggestions were put forward.The mechanized oriented seeding technology for corn will gradually become one of the important development directions in the field of corn seeding in the future,and this paper hopes to provide references for the research,development and popularization of this technology.关键词
