走向法肥效试验设计借助—些有关决定性参数,使试验进程的线性走向具有间断跳跃至目标部位的特点。采用y=A(1—10~(-cx))的经典方程,可满意地达到N、P、K的通常配比的目的。本试验设计采用3×3处理设计方案,其中设一个中心点,作为方案决策的主要意图,其周围设置8个辅助处理,根据不同土壤和耕作条件,随不同的要求而设置,或用作析疑目的。
Approach to the fertilizer test design with the help of some of the crucial parameters, the linear progression of the test process with a jump to the target site characteristics. By using the classical equation of y = A (1-10 ~ (-cx)), the general ratio of N, P, K can be satisfactorily achieved. The design of this experiment adopts 3 × 3 treatment design scheme, in which a central point is set as the main intention of program decision-making. There are 8 auxiliary treatments around it, which are set according to different requirements according to different soil and farming conditions, purpose.
