For a long time, hilly areas have become a bottleneck restricting mechanized and efficient corn planting due to poor terrain conditions and few suitable machines. In recent years, Liangping District has actively explored the mechanized and efficient corn planting technology in hilly and mountainous areas with the School of Agronomy and Biotechnology of Southwest University. By strengthening the transformation of farmland into mechanization, the integration of agricultural machinery and agronomy, testing and demonstrating advanced applicable equipment, and striving to explore a mechanized and efficient corn planting in hilly and mountainous areas Way.

The first is to strengthen the transformation of farmland into mechanization. The transformation of farmland suitable for mechanization is a prerequisite for determining whether large and medium-sized agricultural machinery can operate. In accordance with the principle of complementing, filling, and filling, the dry land with a slope of less than 5 degrees shall be promoted to implement gentle slope reconstruction according to local conditions, and the sharp corners, meniscus and other heterogeneous plots that affect agricultural mechanization operations shall be backfilled, cut and straightened. , Implement more than 2,000 acres of "corn-vegetable" planting bases to be mechanically transformed.

The second is the integration of agricultural machinery and agronomy. The low corn plant height and strong lodging resistance are important conditions for reducing the difficulty of corn harvesting, reducing the loss of corn harvesting, and improving the efficiency of corn mechanized production. Focus on the integration of agricultural machinery and agronomy in planting varieties. Xida 889 and Xida 211 with short plant height and strong lodging resistance are preferred, so that machine sowing and machine harvesting of corn can be used.

The third is to optimize advanced and suitable equipment. In accordance with the full-process mechanized technology model of "mechanical farming-mechanical sowing-mechanical prevention-mechanical harvesting-mechanical deseeding". Choose medium and large tractors as the main small mini-tiller as auxiliary for mechanical farming, choose Nonghaha 2BYFSF-2 machine for sowing, choose DJI T16 for unmanned plant protection, choose Yufeng self-propelled corn harvester to harvest corn on the cob, choose light and simple Corn thresher threshing. Compared with manual planting, the whole process of mechanized corn production can greatly reduce the time cost and labor cost per acre, and it can save nearly 300 yuan per acre and increase efficiency.
