咖啡园恶性杂草白茅的危害及防除
|
摘要
白茅繁殖力和再生力强,适应范围广,发生密度大,一直是云南省小粒咖啡园难于根除的顽固型杂草,本文对云南省主要小粒咖啡产区白茅发生情况进行了普查。结果表明,白茅发生危害率超过30%。文中总结了包括种植前扑杀、间套作物及改善耕作方式在内的农业防治经验,并提出相关化学防除方法,为咖啡园白茅防除提供参考。
Imperata cylindrical L., also known as cogongrass, is a stubborn weed which is difficult to eradicate as its strong fertility and regeneration ability, wide adaptability and high density in the Arabica coffee garden of Yunnan province. The survey conducted in the main coffee plantations of Yunnan has indicated that the damage caused by this weed exceeded to30%. Not the ecological prevention and pretreatment but the chemical control has been presented in this paper, and will thus provided some techniques for controlling the congongrass in coffee plantation.
