Comparative Study On Mechanization Modes Of Silage Maize And Conventional Maize Planting In Shenbei Area

Maize plays an important role in the national economy and strategy of our country,The development of maize production is not only conducive to ensuring national food security and the stability of the grain market, but also can provide more feed and industrial raw materials, promote the development of stockbreeding and other related industries.Maize is the primary grain crop in Liaoning, and it possess nearly half of the grain crop planting area.However, with the development of stockbreeding, the North of Shenyang began to plant wide areas of corn silage.In this paper, we start with the analysis of the corn silage and conventional planting mechanical model in the north of Shenyang,and then we conduct economic evaluation of the the corn silage, the equipment plan and technology of the conventional planting mechanical production equipment, After that we analysis the comparison of the efficiency of corn silage in the north of Shenyang and conventional planting mechanical production in the North of Shenyang, provide a reference for promoting the development of corn mechanization in the New Area of the North of Shenyang.The main results of this paper are as follows:(1) the adaptability analysis of corn silage and conventional corn planting mechanization production technology and equipment in the north of Shenyang.Through the the user survey and the analysis of the performance of the main machines, and refer to the agricultural machinery subsidy policy of the state and government,We focus on the adaptability of corn silage and conventional corn planting mechanization production technology and equipment.Thus established foundation to equipment selection.(2) Analysis on the appropriate pattern of corn silage and conventional corn planting mechanization production equipment in the north of Shenyang.We established mathematical model of the cost of the main main operating machinery include mechanical tillage, sowing cultivation machinery, plant protection machinery and harvesting machinery in these two planting patterns. Furthermore, the operation efficiency, the minimum and the maximum operation scale of the main machines are also analyzed, which provides the basis for the reasonable equipment.(3)The planting plots in the north of Shenyang area were studied.We equipped corn silage and conventional corn planting mechanization production, and compared these two models in the economic view.Using technical economics analysis method, the economic evaluation and benefit analysis of the equipment plans of the two planting patterns, the results show that the corn silage economic benefit is obvious.
