Preemergence Herbicidal Activity of Soybean Meal and Its Ecological Effects on Soil Microbes

Abstract

杂草危害是农业生态系统和城市草坪管理中面临的主要问题之一。杂草的化学防治一直是杂草控制的主要手段,但化学除草剂的过度使用所带来的环境安全问题已日益受到公众的关注,而寻求天然无公害的除草剂被认为是解决这一弊端的有效途径之一。豆粕是大豆经过提取豆油后得到的一种副产品,含有40%~48%蛋白质,是一种常见的动物饲料。本文研究了豆粕及其水解物对植物种子萌发的抑制活性(以下称为萌前除草活性)及作用机制,评价了豆粕对成熟草坪植物、草坪质量及草坪土壤微生物多样性的影响。此外,还比较研究了与豆粕组成相似的玉米蛋白粉的萌前除草活性机制。上述研究为阐明豆粕乃至其他天然蛋白原料及其水解物的除草活性机制,为豆粕开发成...Synthetic herbicides are often used for weed control in agriculture ecosystem and turfgrass management. Public awareness of the widespread use of herbicides and the possible negative effects of their residues on the environment have led to increased efforts in the search for natural herbicidal active products. Soybean meal (SBM) is a byproduct of soybean oil extrcation, it contains 40%-48% protein...学位:工学博士院系专业:海洋与环境学院环境科学与工程系_环境工程学号:B20043401
