Three dry rice cultivation, that is dry nursery seedlings, dry land preparation, drought management. It is a comprehensive technical measure based on the characteristics of water shortage and rainfall season in Linyi, Shandong Province, taking advantage of its own stage of drought tolerance and water saving as the center, stabilizing and expanding rice acreage and increasing yield per unit area. In the past, Linyi rice paddy mainly relied on paddy water for paddy cultivation. Because of the inability to control the storage of paddy water, paddy field area was not stable enough, which brought many difficulties to production.
