During the period of the Sixth Five-Year Plan, our country organized scientific research by the State Science and Technology Commission and confirmed through technical appraisal. Under the condition of conventional fertilization management, we can make rice, wheat, tobacco, peanut, soybean, tea, sugar cane and other 13 Crops to increase production and improve the quality of the results, which in our country to develop a new field of rare earth agriculture.
