一、问题的提出水稻生产耕整机具的选型,在很大程度上取决于耕作制度、耕作方式等方面的变化和改革,因此,农机必须与农艺紧密结合,将耕整机具的选型研究建立在先进可行的耕作制度和耕作方式的基础上。稻田耕作制度自五十年代改革以来,至七十年代初,已逐步形成了以绿肥双季稻为主的一肥两熟制,对前段时期水稻的增产起了很大的作用。但由于长期连作,稻田灌水 First, the issue put forward The choice of rice production tillage equipment, largely depends on the farming system, farming methods and other aspects of change and reform, therefore, agricultural machinery must be closely integrated with agronomic, Type research is based on advanced and feasible farming systems and farming methods. Since the reform of the 1950s, till the early 1970s, the system of paddy field farming has gradually formed a double cropping system based on double-cropping green manures and played a significant role in the increase of paddy output in the previous period. However, due to long-term continuous cropping, paddy field irrigation
