使用联合收割机是抢农时、保收成的重要手段。随着科技创新和技术进步,各种新型联合收割机不断涌现,技术质量水平不断提升。然而,农民用户对联合收割机作业质量的要求也越来越高。这就需要在大力支持企业研制开发技术先进的高性能联合收割机的同时,更要深入开展联合收割机试验和质量评价技术方法的研究,以确保质量评价的科学性和准确性。谷物穗幅差是联合收割机的重要试验条件和评价指标,其准确性直接影响联合收割机的作业性能和适用性评价。
Use of combine harvester is grab farming, an important means of insurance revenue. With the technological innovation and technological progress, various new combine harvesters continue to emerge, and the technical quality is constantly improving. However, farmers’ requirements for the quality of combine harvester are also getting higher and higher. This requires the support of enterprises to develop advanced technology and high-performance combine harvester at the same time, but also to conduct in-depth study of combine harvester test and quality evaluation of technical methods to ensure the quality of scientific evaluation and accuracy. Spike amplitude of cereals is an important test condition and evaluation index for combine harvesters, and its accuracy directly affects the operational performance and applicability of the combine harvester.
