作者根据黑龙江省土壤耕作制现状,主要粮食作物的高产农艺要求,通过实践,分别提出为大、小型拖拉机配套的更新换代机具及其旱作耕种机器系统(表)。其中就新机型的选择、研制、性能指标及麦豆、杂粮产区采用的相应机械化高产工艺方案进行了重点研究。 Based on the status quo of farming system in Heilongjiang Province and the requirements of high-yielding agronomic crops of the main grain crops, the authors put forward the upgrading machines for large and small tractors and their dry farming systems (tables) respectively. Among them, the selection of new models, research and development, performance indicators and malt bean, miscellaneous grains producing areas of the corresponding mechanization of high-yield process programs were focused on.
