吉林省黑土区玉米精准施肥技术研究与应用

Study and Application of Maize Precision Fertilization Technology in Black Soil of Jilin Province

应用地统计学、专家系统、地理信息系统和智能农机等技术,研究了吉林省黑土区土壤养分变异规律,提出了适于黑土区的玉米精准施肥模型,开发了玉米精准施肥专家系统,并通过变量施肥机进行了精准施肥的应用。与传统施肥方案相比,精准施肥使玉米增产10%以上,节肥率达到15%。

Geo-statistics, expert system, geographical information system and intelligent agricultural machinery are applied in the article. By the above methods and technology, spatial variability of soil nutrient is studied, precision fertilization model of maze is introduced, expert system of maize precision fertilization is developed. Finally, the precision fertilization is implemented by the variable rate fertilizer. Compared with the traditional fertilization, the precision fertilization made the maize production increase by 10% and made the fertilization amount decrease by 15 %.
