生态平衡施肥模型与目标产量施肥模型比较研究
Comparison of Target Yield Method and Ecological Balanced Fertilization Model
摘要
Abstract
This paper discussed the characteristics, shortcoming and estimated dosage precision of target yield method(TYM), and compared with those of the ecological balanced fertilization model(EBFM). The results showed that the structure of TYM was reasonable and parame-ters were easy gotten. However, the fatal disadvantages of TYM were variable multi-parameters system with accurate parameters hardly be gotten, interactions among parameters, and less consideration of exchange item of soil available nutrient. Therefore, it was hard for TYM to be widely applied as an accurate fertilization model. In comparison with TYM, EBFM was an universal, quantitative and mechanism model, which was established based on the mass conversation law and the relationships of available nutrient transformation between soil, fertilizer and plant. As EBFM had the dual functions of fertilizer effect function method and soil testing&fertilizer recommendation(TYM was a typi-cal one), it had many strongpoints, such as complete functions, plenty information, less parameter variations, accurate measurement, easy for obtaining parameters, precise calculation, etc.关键词
