针对饲草在田间干燥干物质损失大和营养成分保持率低的问题,提出了牧草湿法收获工艺的技术原理、工艺路线,为太阳能饲草干燥实现规模机械化提供技术支撑,设计了可直接进行整捆饲草干燥的太阳能草捆干燥设备.该设备能实现太阳能的自动采集并对含水率在40%左右的整捆饲草进行干燥处理,成品草捆可直接进行贮藏.设备的性能试验和牧草干法收获与湿法收获对比试验结果表明:太阳能干燥饲草损失率小于等于2%,成品草捆含水率小于等于17%,太阳能空气集热器白天平均热效率大于等于0.5,处理能力大于等于1 t/h.%Aiming at exiting problems of flowers and leaves as well as the nutrition loss by using the dry harvesting technology process in field for forage grass, the introduction for the wet harvesting technology process innovation and its advantages of forage grass in different views was gave, such as technological theory and technological process. And in order to provide technical support for forage grass dimension mechanization desiccation by using solar energy, one type of solar energy bale drying machinery was developed. It could work in solar automatism collection manner and dry the bale of moisture content in around 40% . Products could be directly baled and stored. The performance test of the equipment and the dry grass and wet harvest were experimented. The tested results were listed as follows; solar drying forage loss was less than or equal to 2% , finished bale moisture content was less than or equal to 17% . The collector efficiency of solar energy air was more than or equal to 50% and handling ability was more than 1 t/h.
