摘要
旱地节水型播种机是以农村拥有量大的拖拉机为动力，以播种机为基础，集取水、运水、男间播种施水为一体的农业机械。在我国干旱影响面广，旱灾频次高、农田水利基建投资不足和现有经济体制条件下，使用该机械可利用各种水源，机动灵活地运水施水，解决旱田旱期播种出苗保苗的问题。
Rainfed farmland water saving seeding machinery with tractors as its power in the rural areas is an integrated farm machinery based on seeding machine integrating seed sowing,water carrying,transporting and irrigating in the fields.In China,there is a vast drought area with frequent occurence of drought disasters,and there is not enough fund for farmland water conservancy construction.Accordingly,under this condition,using this machinery can utilize available water resources,carry and transport water for irrigation in sowing flexiblly in solving the problem of seedling emergence and seedling preservation sowing in rainfed farmland in dry season so as to achieve the purpose of sowing by water saving.
