Abstract

The invention discloses a decision support system for cropland management and fertilization, belonging to the technical field of agricultural information. The system of the invention manages the regional cropland quantity, the farmland production condition and the soil nutrient condition on a visual map, and provides scientific fertilization guidance for farmers. By means of the invention, the problems of reduction of cropland quality, unbalanced fertilizer utilization, unscientific cropland utilizing and nourishing management and unscientific management on crop growth processes are solved. The invention can ensure that cropland management and fertilization guidance of croplands aiming at any county is finished. By providing the results acquired by perennial field experiments and the knowledge of experts for farmers, the invention has the advantages that scientific fertilization is realized according to different climate and cultivation conditions as well as cropland soil fertility conditions, and decision makers can carry out visual management on farmland conditions. The invention constructs a technical support platform for ensuring national food security, and has practical significance.

Description

technical field [0001] The invention belongs to the field of agricultural information technology, and in particular relates to managing the quantity of cultivated land in a region, farmland production and soil nutrient status on a visualized map, so as to provide farmers with scientific fertilization guidance. Background technique [0002] At present, the contradiction between man and land in our country is prominent. According to the figures released by the Ministry of Agriculture and the Ministry of Land and Resources, in the eight years from 1996 to 2004, the area of ​​cultivated land in our country decreased from 1.951 billion mu to 1.837 billion mu; in 2005, it decreased by 5.4 million mu; in 2006 Reduced by 10 million mu. my country currently has a population of 1.3 billion, of which 940 million are agricultural population, and there are about 250 million farm households. The average cultivated land area per household is only 7 mu, and the national per capita cultivate...
