研究有机质的变化规律,有助于充分开发和利用有机肥源,自1976年开始,我们就有机质的易氧化百分率,有机质的月变化以及二氧化碳释放速率等三个方面进行了三年的研究。 一、有机质的易氧化百分率 为了了解有机肥料中有机质的活性,我们进行了不同有机质包括葡萄糖、面粉、田菁、柽麻、麦秸、高粱秸、猪粪、马粪、风化煤、滤纸在相同碳氮比、湿度、温度下自然发霉试验。其中发霉最快的为葡萄糖、面粉。其次是田菁、柽麻。再次的为高粱秸、猪粪,在3～5天就开始长霉。麦秸、马粪等半月左右才进入发霉高潮。滤纸代表纯纤维素,基本上不变。一个月才断裂。用风化煤进行试验,几个月不变。 这些试验表明,不同的有机质腐解活性不同。是
Studying the variation of organic matter will help to fully exploit and utilize organic fertilizer sources. Since 1976, we have conducted a three-year study on three aspects of the percentage of organic matter susceptible to oxidation, the monthly variation of organic matter, and the rate of carbon dioxide release. First, the percentage of easy oxidation of organic matter In order to understand the organic fertilizer organic fertilizer activity, we conducted a different organic matter, including glucose, flour, Sesbania, flax, wheat straw, sorghum straw, pig manure, horse manure, weathered coal, filter paper on the same carbon Nitrogen ratio, humidity, temperature, moldy natural test. One of the fastest molds for glucose, flour. Followed by Tian Jing, hemp linen. Again for sorghum straw, pig manure, in 3 to 5 days to grow mold. Wheat straw, horse manure and other half or so into the moldy orgasm. Filter paper represents pure cellulose, essentially unchanged. A month before breaking. Test with weathered coal, a few months unchanged. These tests show that different organic decomposing activities are different. Yes
