摘要： 根据吉林省中部地区的气候条件和土壤肥力状况,为改善种植结构,建立新的生态平衡,考虑到用地与养地结合及种植习惯,以高产、稳产、高产值为目标,运用线性规划的方法,提出了主要旱田作物(玉米、高梁、谷子、大豆)的最佳种植结构.如按照规划的比例种植,总产量将提高3.5%,总产值增加11.0%.

Abstract: Based on the climatic condition and level of soil fertility in the Middle region of Jilin and the purpose of high-yield,stableyield,high income,through applying the method of linear programming,the author suggests the best planting structure of main field crop in this paper,inclusive of corn,grain, soybean and sorghum.The best proportion is 65.4 percent for corn,sorghum 0 percent,grain 15.0 percent,and soybean 19.6 percent.The total yield will be increased by 3.53 percent,and the income will be increased by 11.03 percent if according to the this structure. For considering the planting habit,the author suggests also to adopt following proportion,i.e.sorghum 5 percent,corn 59.12 percent,grain 15 percent and soybean 20.84 percent.In this way,the income will be increased by 9,60 percent.
