本文着重探讨沼气肥与一般习惯堆制的有机肥在酵解过程中养分变迁和养分形态,并分析水稻和麦子增产的原因。 1979～1980年间,我们与上海县华漕公社候家角大队,松江县城西公社联丰大队第五生产队、奉贤县齐贤公社种子场协作,进行沼气肥和习惯堆制有机肥(简称堆肥)的定点对比肥效试验,还在院内进行了相应处理的盆栽试验和发酵模拟试验,以及分析了土壤、肥料、植株的全氮、全碳、水解氮等有关项目。现将试验结果综述于后。结果与分析 1.发酵过程中养分变化及损耗沼气肥是嫌气酵解的,养分逐渐由固相转为液相,含氮有机物的量和质与一般堆制
This article focuses on the nutrient changes and nutrient patterns of biogas fertilizer and common organic fertilizer in the process of digestion and analyzes the reasons for the increased yield of rice and wheat. From 1979 to 1980, we collaborated with the Fifth Production Team of Lianfeng Brigade of Huacao Communities in Shanghai County, the Fifth Production Team of Lianfeng Brigade in Chengxi Commune of Songjiang County, and the Seed Field of Qi Xian Commune in Fengxian County to carry out biogas fertilizer and custom composting organic fertilizer ), And compared with the pot experiment and the fermentation simulation test in the hospital, and analyzed the related items such as total nitrogen, total carbon and hydrolyzed nitrogen in soil, fertilizer and plant. The test results are summarized later. Results and Analysis 1. Changes and losses of nutrients during fermentation Biogas fertilizer is too bacteriolytic. Nutrients gradually change from solid phase to liquid phase. The amount and quality of nitrogenous organic compounds
