摘要： 三种吨粮田在立体种植条件下,自然地增加了受光面积,延长光合规模周期,使生理、生态和物质代谢产生了明显的优势.建造了大量的光合产物,促进生长中心较早较快地向果穗转移,延长产量形成期,创造良好的高产生长规律,为在热量资源种一季有余、种两季不足的地区建设吨粮田提供科学依据.

Abstract: In stereoplanting condition, three kinds Ton-grain farmland naturally has added illuminated areas, photosynthesis dimensions period has prolonged It has produced clear superiority to the physiology and ecology and material supersession, produced a large number photosynthetic product, has accelerated growth center to early and rapidly change to the spike, has prolonged field formed period, has created good high-field growth pattern, have provided scientific basis witht the areas which heat resources supply one crop odd, supply short of two crops, have builded Ton-grain harmland.

Key words: Wheat, Corn, Stereoplanting, Ton-grain farmland
