摘要
BGA是一种由城乡有机废弃物经资源化处理后制得的有机抗旱肥料,它的推广应用有利于缓减我国水资源紧张和严重环境污染的压力。以3年多的试验资料为基础,用BGA对大叶黄杨生长、生理过程的影响作为主要阐述对象,结合同类产品的研究成果(如有机肥料),从土壤含水量的变化,植物的生长、光合、蒸腾特性以及水分利用效率等方面,比较系统地总结了BGA的节水调控机制。针对不同植物,推荐了BGA的施用量和施用方法。
BGA is a kind of organic draught-resistance fertilizer, which is made from organic garbage in town or rural area. Its spread and application is benefit to relieve the pressure of water resources scarcity and serious environmental pollution. Based on the experi mental data during three years, through analyzing the influence of BGA on the growth and physiological process of euonymus japoni cus and combining the research results of the similar production such as organic fertilizer, this paper roundly explored the water sav ing regulating mechanism of BGA from the aspects of soil moisture, growth, photosynthesis, transpiration and water use efficiency of plants. The dosage and using ways of BGA for various plants were recommended in the end.
