Design And Implementation Of WebGIS-based Soil Nutrient In Field Of Cotton Manage & Recommend Fertilizing Information System In Xinjiang

Mastering information of soil and fertilizer in time is an important basis in the measure of scientific regulates and control agricultural production. People considered that equilibrium fertilization technology is a riper modern fertilizing technology in the inland and overseas, and computer recommend fertilizing system was proved to be very effective popularizing equilibrium fertilization technology measures, with the advancement and popularizing application of network technology, computer recommend fertilizing should also develop networkward. This dissertation was on the basis of the demand of soil nutrient in field of cotton manage, equilibrium fertilization technology and service of soil fertilizer information, by the way of integration of agriculture and information Science and technology, on the basis of soil test, fertility test, and study of recommend fertilization model, applying the theory of crop equilibrium fertilization, database technology, Java technology, WebGIS technology, and expert system technology, aim at district soil fertility, quality of soil, according the demand fertilizer characteristic of different cotton breeds, considering field as a handling unit, developed a information system of soil nutrient manage, open fertilizer model parameter manage, according recommend fertilizer amount clustering to produce special fertilization, WebGIS browse query and by internet to manage soil fertilization etc characteristic. This system has practicability and hi-tech. When it applied in the demonstration district, advanced country management, increased application areas, made farmer gain more profits. The study will also promote the construction of "digital agriculture" and protect country's environment of Xinjiang. This system gives foundation to the going on of the following tasks.
