This study examined the collection, storage, and utilization of ear corn residue as a bulking agent for composting. Ear corn residue left in fields was collected by a sequence of windrowing and round baling operations, which showed a collection efficiency of 53%-56%. More than 70% of the corn stalks had lengths shorter than 15 cm. The moisture content of corn residue collected in late October was approximately 58%; it decreased to 23% during storage. Dried corn residue was mixed with raw manure in two different ways, namely using complete mixing (CM) treatment or creating a bottom layer of residue, and a total of 3.4 t of the manure and ear corn residue mixture were composted using a pilot-scale composting apparatus. The results showed that the CM treatment resulted in higher temperature generation and produced less odorous and well-degraded compost after 2 months of composting, while the odorous compounds in the compost with corn residue as the bottom layer remained similar to those of the initial compost. To sufficiently utilize the advantages of the ear corn residue, thorough mixing of the corn residue with raw manure is preferable; this procedure produced well-degraded and safety compost in a shorter time period.

玉米穗渣的收集及其作为牛粪堆肥膨胀剂的利用。

本研究考察了玉米穗残渣作为堆肥填充剂的收集、储存和利用。通过一系列堆垛和圆捆作业收集留在田间的玉米穗残渣，收集效率为 53%-56%。超过 70% 的玉米秸秆长度小于 15 厘米。10月下旬收集的玉米渣含水率约为58%；储存期间下降到 23%。将干玉米渣与生肥料以两种不同的方式混合，即使用完全混合 (CM) 处理或创建渣土底层，并使用中试规模对总共 3.4 吨的肥料和玉米穗渣混合物进行堆肥堆肥设备。结果表明，经过 2 个月的堆肥处理后，CM 处理产生的温度更高，堆肥气味更小且降解良好，而以玉米渣为底层的堆肥中的气味化合物与初始堆肥相似。为充分发挥玉米穗渣的优势，最好将玉米渣与生肥充分混合；这个程序在较短的时间内产生了良好降解和安全的堆肥。
