The rice transplanting water drainage causes fertilizer nutrient loss and pollutes the environment, and the special fertilizer for rice is thrown into water, so that the fertilizer far away from the rice root system cannot be absorbed, and the practical problem that the yield of the rice is increased is troubled by how to solve the problems of excessive fertilization and low fertilizer utilization rate. The adoption of side deep fertilization is an advanced scientific method. High yield can be realized only by deep side fertilization if the fertilization utilization rate of the rice is high. One large piece of fertilizer is applied, which is not as good as one line, while the rice seedling is accurately transplanted, the fertilizer is applied to the root part of the side surface of the rice seedling at the position with the depth of five centimeters, the rice side deep fertilization technology is used for realizing the synchronization of transplanting and fertilizing, the green turning and tillering are not required to be toped, the manual operation times are reduced, the using amount is reduced compared with the traditional fertilizer application, the labor input cost is saved, the fertilizer utilization rate is improved, the fertilizer input is reduced, the fertilizer utilization rate is improved by more than 35 percent, the sufficient nutrient supply during the rice growth period is ensured, the early and quick rice tillering is promoted in time, a good group structure is formed, the rice tillering is increased, and the unit weight of spike grains and dry matters is improved. Thereby improving the yield quality and the benefit. The side deep fertilization needs an integral combination system with very strong speciality, technicality and scientificity, the production process technology and the like, the fertilization machinery is specialized, the second fertilizer needs to be uniform in particle size, good in particle surface smoothness, strong in particle hardness, good in particle surface waterproofness, uniform in fertilization, accurate in dosage and better suitable for the requirement of large-scale planting. The traditional fertilizer has rough particle appearance, uneven particle size, poor particle hardness and incapability of preventing water on the particle appearance and normally fertilizing on a rice transplanter, and therefore, a technical production process of the special fertilizer for the lateral depth of rice is provided.
