一、目的 我国長江下游的水稻栽培制度,大致可分为双季連作稻及稻麦兩熟兩个主要类型。农民在水稻田整田时一般要經过多次耕、耙、耖田等作業,使土壤达到細碎、松軟、平整后再行插秧。在稻麦兩熟地区小麦田整田时,土壤湿度大,要在耕田时作畦碎土,其要求与水稻田不尽相同。目前,不論哪种田的整田作業都还是应用一些旧式耕具,为了适应当前我国农業生产跃进的需要,新式的水田耕具迫切需要解决,以提高劳动生产率及水稻与小麦 First, the purpose of China’s lower reaches of the Yangtze River rice cultivation system can be divided into two quarters even for rice and rice two ripe two main types. Farmers in the paddy fields when the field generally go through several tillage, rake, 耖 Tian and other operations, so that the soil reached crushing, soft, flat after planting. In whole wheat fields in the wheat-wheat and double-ripening areas, soil moisture is high and soil must be ground for farming. The requirements are different from paddy fields. At present, no matter what field of field operations are still using some old tools, in order to adapt to the current needs of our country’s agricultural production leap forward, the new paddy tools urgently need to be addressed in order to improve labor productivity and rice and wheat
