小麦、夏玉米一体化栽培理论探讨

通过试验和分析明确了小麦、夏玉米“一体化栽培”的三大理论基础,即作物与气候的时空统一律、两作物栽培生理学特性互补律及一体化栽培的气候学基础;总结发现了两种作物的7个生物学互补特性,提出了7个方面的技术对应关系;并建立了小麦夏玉米一体化栽培的科学新概念,为提高光热利用效率,增加单位土地面积产出提供了理论依据。

STUDY ON THE PRINCIPLES OF WINTER WHEAT AND SUMMAR MAIZE INTEGRATED CULTIVATION IN NORTHERN CHINA

Through years of experiments and analysis, three main essencial principles about winter wheat and summar maize integrated cultivitave technology were proposed. The principles include: the principle of crops unifying withlocal climate in lime and space; the principle of winter wheat and summar maize inter-compensating in properties of cultivative physiology; the background of the integrated cultivation. Based on seven biological inter-compensative properties of the two crops, seven aspects of technological correspounding relations were established, and a scientific concept of "winter wheat and summar maize integrated cultivation" was also formed. A set of relatively precise and complete theoritical system for increasing the output of unit land area by elevating lilt and heat utililzing rate was uttered in the paper.
