"3414" Fertilizer Effect Field Trial

1, the purpose of the experiment fertilizer effect field experiment is to obtain a variety of crops the best amount of fertilizer, fertilizer ratio, fertilization period, fertilization method of the fundamental way, but also the screening, verification of soil nutrient testing methods, the establishment of fertilization index system of the basic link. Through field trials, the number of fertilizers optimized for different fertilizer application units in different crops, basis, top dressing distribution ratio, fertilization period, and fertilization method; find out the soil nutrient correction factor, soil fertility, different crop nutrient uptake and fertilizer utilization and other basic parameters Construct crop fertilization models to provide basis for fertilization partitions and fertilizer formulations.
2. Experimental design Fertilizer effect Field trial design depends on the purpose of the study. This technical specification recommends the use of "3414" scheme design. In the specific implementation process, a "3414" complete implementation plan and some implementation plans can be used according to the research purpose.
The "3414" program design absorbs the advantages of less regressive optimal design processing and high efficiency. It is a widely applied fertilizer-effective field trial program at home and abroad. "3414" refers to nitrogen, phosphorus, and potassium three factors, four levels, and 14 treatments. The meaning of the 4 levels: 0 level means no fertilization, 2 levels means local optimum fertilization amount, 1 level = 2 level 0.5, 3 level = 2 level 1.5 (this level is excessive fertilization level).

In addition to applying 14 treatments to fit nitrogen, phosphorus, and potassium ternary quadratic effect equations, the program can also be fitted with arbitrary binary or one-dimensional effect equations for nitrogen, phosphorus, and potassium.
