Soil nutrient evaluation and recommended model for Chinese gooseberry fertilization based on GIS

Based on GIS management of soil nutrient in Zhouzhi County of Shaanxi Province, the distribution model and suitable rank division were obtained by computation. In view of the Chinese gooseberry characteristics, the demanding model has been established. Thus in view of the soil nutrient spatial distribution character the suggestion on the policy-making instruction significance to apply fertilizer was put forward to improve the quality and output of the Chinese gooseberry. On the basis of the model of the fertilizer suggestion, fruit tree fertilization information system was established. This method has realized spatial, visible and systemic management of soil nutrient data under the GIS support, in the greatest degree of realizing continuous nutrient distribution model construction. Visualized output of fertilizer applying suggestion for the different regions can be realized. This method is a beneficial exploration to realize "digital agriculture" and "precision fertilization", which has the certain theory and the practice significance.
