玉米立体种植增产机理的研究

Studies on the Mechanism of Yield Increase of Corn by Means of Intercropping

玉米间大豆是一项较成功的立体种植技术。已有研究表明玉米间大豆在时间、空间、地力、养分的分配等方面相互影响、相互制约 ,以各自的增减达到总体的平衡 ,构成全年综合产量。在产量、产值、产能、纯收益等方面较之单作玉米和大豆有优越。本文主要揭示玉米间大豆后 ,从生理、生态、栽培、耕作等角度出发 ,阐述其增产机理 ,为玉米的立体种植提供理论依据。

Corn intercropped with soybean is a successful multistorey cropping technique. Researches show that when corn is intercropped with soybean, the two crops interact in the distrubution of time, space, soil fertility and nutrient. An overall balance and integrated output are achieved through respective increase and decrease. It wins an advantage over cropping corn and soybean alone in the quantity, value capacity, net profit of output. etc. From the angles of physiology, ecology, cultivation and geoponics, this article explains the mechanism of yield increase and offers theoretical basis for multistorey cropping of corn.
