摘要
农林复合系统、间作及套作中植物组分之间养分竞争普遍存在。植物的养分竞争主要包括种内竞争和种间竞争。光照、温度、水分、土壤、微生物。低等动物等外界因素对植物的竞争作用具有明显的影响。农林复合系统中 ,林种和林间作物品种的选用。
Nutrients competition between component parts are commonly happened in the agroforestry and inter cropping systems,which can occur between crops of one or more species.Illumination,soil temperature,soil moisture,and microorganism,low forms of animals in soil affect nutrients competitions significantly between plants.In order to get good harvests from intercrops,the nutrients competition should be reduced in the agroforestry.Partner of tree and crop selection,tree clip and crop management might be used to control nutrients competition in agroforestry and agriculture management.
