Rice, one of the three major crops in the ningxia irrigation area of yellow river. is widely planted. the traditional irrigation techniques of rice are flood irrigation and deep storage. which need more water consumption and have higher application volumes. with the increase in population, the development of industrial and agricultural production and the uniform catchment agreement for the water resource of yellow river, the supplying and demand contradiction of the water resources in ningxia is more evident, then drang is presented for developing water - saving and efficient agriculture

However, the rate of rice - transplanting by machine was at a low level, only 2. 8 percent in our country at present. it was mainly due to the low reliability of the rice transplanter produced in our country. moreover, the price of foreign high - speed rice transplanter was high and they could not fit the high rice seedlings of the autumn season in the south of china
