The construction of the evaluation index system is also called the evaluation system index construction. It is an important part of the soil testing and fertilizer application system and is the main method for screening and verifying the soil nutrient testing methods. The construction of the FX3414 evaluation index system is to be developed in accordance with the "3414" program, which is widely used in the field of soil testing and fertilizer application. The following will introduce the "3414" complete implementation plan.
The "3414" program design absorbs the advantages of less regressive optimal design processing and high efficiency, and is currently a widely applied fertilizer effect field trial program. "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 recommended fertilization amount, 1 level (refers to under fertilization) = 2 levels × 0.5, 3 levels (refers to excessive fertilization) = 2 levels × 1.5. For the sake of summary, the same amount of fertilizer should be kept in the same area and in the same area. If you need to study the effects of organic fertilizers and trace element fertilizers, you can add treatments based on this.
The program can use 14 treatments to fit nitrogen, phosphorus, and potassium ternary quadratic effect equations, and can also fit any binary or one-dimensional effect equations for nitrogen, phosphorus, and potassium.
For example, when fitting a nitrogen and phosphorus binary effect equation, you can use treatments 2 to 7, 11, and 12 to determine the binary effect equation of nitrogen and phosphorus at the K2 level; choose treatment 2, 3, 6,11 can be obtained based on the nitrogen fertilizer effect equation based on P2K2 level; selection of treatment 4,5,6,7 can be obtained based on N2K2 level of phosphorus fertilizer effect equation; selection processing 6,8,9,10 can be obtained Potassium effect equation based on N2P2 level. In addition, through processing 1, it is possible to obtain basic ground productivity, ie, blank area production.
Its specific operation refers to the relevant experimental design and statistical data.
