小麦间作蚕豆体系作物生长曲线动态模拟与分析
Dynamic Simulation and Analysis of Crop Growth Curves in Wheat and Faba Bean Intercropping System
摘要
Abstract
By utilizing dynamic growth data of crops in the wheat/faba bean intercropping system and Logistic growth curves,this study provides scientific evidence for the interactions between wheat and faba bean in monoculture and intercropping systems.The dynamic changes in biomass under different nitrogen levels were simulated and analyzed for wheat and faba bean in monoculture and intercropping systems.Results indicated that in intercropping treatments,the competitive accumulation rate ratio between crops exhibited a parabolic trend of competitive recovery.Under both fertilization treatments,monoculture faba bean reached its maximum growth rate earlier than intercropped faba bean.After wheat maturity,the competition from wheat decreased,allowing the growth rate of faba bean to recover.Under the same planting pattern,nitrogen application played a critical role in biomass accumulation of faba bean.In intercropping and nitrogen-deficient environments,the biological nitrogen fixation effect of faba bean was stimulated,promoting below-ground growth and increasing the number of nodules.In summary,nitrogen application and intercropping altered the biomass accumulation of wheat and faba bean.During the early growth stage of faba bean in the wheat intercropping system,wheat showed a strong advantage in nitrogen utilization,which affected the above-ground and below-ground biomass accumulation of faba bean.This reflects the growth potential of the crops and their capacity to utilize nutrient resources.关键词
