不同行距配置下玉米种内间作对地上-地下部互作及产量机制的研究进展
Progress in the Study of Above-ground and Below-ground Interactions and Yield Mechanisms of Intra-row Maize Intercropping Un-der Different Row Spacing Configurations
摘要
Abstract
Intra-row intercropping in maize exhibits potential in optimizing population spatial structure,thereby enhancing resource use effi-ciency and achieving stable yield increases.This paper systematically integrates recent research progress on the effects of different variety com-binations under equal-row and wide-narrow row spacing configurations,focusing on canopy structure,photosynthetic characteristics,root spa-tial distribution,and yield formation mechanisms.Studies have shown that appropriate row spacing configuration(such as wide-narrow row planting)can increase the leaf area index(LAI)and improve light interception in the middle and lower canopy layers by creating a"wave-like"canopy architecture,thus enhancing the overall photosynthetic efficiency of the population.At the same time,such configurations pro-mote deeper root development,increase root length density in the 0-40 cm soil layer and improve the root system's capacity to acquire water and nutrients.Coordinated regulation of planting density and row spacing can result in a yield increase of up to 34.2%under certain threshold conditions(e.g.97 500 plants/hm2 with a 56 cm+24 cm wide-narrow row configuration).Future research should focus on constructing a syn-ergistic model of"density×row spacing×variety"to elucidate aboveground-belowground interaction mechanisms,thereby providing theoretical basis and technical support for high-yield and high-efficiency maize cultivation.关键词
