采用二次通用旋转回归组合设计试验,运用PB700进行结果统计分析,研究了氮钾锌肥配施对土壤养分的影响。结果表明,氮钾锌配施可以协调土壤养分和作物生长之间的矛盾,研究结果为玉米平衡施肥提供了依据。
Using quadratic universal rotation regression combination design test, using PB700 statistical analysis of the results to study the nitrogen, potassium and zinc fertilizer on soil nutrients. The results showed that the combination of NPK and Zn could coordinate the contradiction between soil nutrients and crop growth. The results provided the basis for the balanced fertilization of corn.
