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
如果我國插秧機械化水平提高1 ,每年就能
增產糧食3 . 75億kg ,但目前我國的機插率只有2 . 8 ,其主要原因是國產插秧機的可靠性低,而進口的高速插秧機價格太高且對我國南方雙季
