水稻旱种就是象种小麦那样,直接把水稻种在旱地里,先旱长一阶段,然后再间歇灌溉的一种水稻栽培方法。它的主要优点是能够大量节约用水,其用水量只有水种的1/4左右,同时省工、省肥。采用这种方法,可以解决关中地区水稻生产中普遍存在的水源不足、土地漏水、用水量过大、成本过高并影响旱粮灌溉的问题,因此,在北方气候、土质、水利等条件下,水稻旱种比水种更能高产稳产。为了选出和繁育一批适应本地旱种的水稻品种,同时掌握水稻早种的技术,一般先要
Dry cultivation of rice is a rice cultivation method that, like wheat, directly plants rice in the dry land, takes a long, long period and then intermittently irrigates it. Its main advantage is that it can save a lot of water, its water consumption is only about 1/4 of the water, at the same time labor-saving, provincial fertilizer. In this way, we can solve the problems of insufficient water source, water leakage, excessive water consumption, high cost and affecting irrigation of dry grain in Guanzhong area. Therefore, under the conditions of northern climate, soil and water conservancy, Dry cultivation of rice is more stable than water. In order to select and breed a batch of rice varieties that adapt to local dry farming while mastering the technology of early planting rice,
