Embodiment 1

[0019] Take the planting of radishes in a certain place as an example, the planting area is two acres.

[0020] 1. Soil nutrient testing

[0021] 1) Sampling

[0022] Randomly select 15-20 points in the radish planting area, uniformly and randomly sample according to the zigzag or snake-shaped distribution, and the sampling soil depth is 0-30 cm.

[0023] 2) Detection

[0024] Air-dry the soil sample, perform pre-treatment, detect soil nutrients, measure soil pH, organic matter, available nitrogen, available phosphorus, available potassium, and medium and trace elements to obtain test values;

[0025] 2. Fertilizer formula

[0026] According to the nutrient test results of soil samples and related soil classification standards, determine the soil fertility of the plot, determine the target yield, and then combine the growth requirements of radish to determine the nutrients needed by radish, and then determine the fertilizer formula through calculation, according to availabl...

Abstract

The invention discloses a method for radish soil testing and formulated fertilization. Currently, farmers mainly use fertilizer in farming and fertilization, however, soil is hardened, the yield and the quality of crops are reduced, and environment problems of lost and unbalanced soil nutrient, non-point source pollution and soil acidification are caused. A soil test and a fertilizer field test serve as a basis, and according to radish fertilizer requirement laws, nutrient preserving capability and fertilizer response, the application amount, the application period and the application method of fertilizer such as nitrogen, phosphorus, potassium, microelements and secondary elements are provided on the basis of reasonable organic fertilizer application. The scientific fertilizer application is applied in accordance with radish growth rules, the fertilizer utilization rate is improved, the soil fertility is improved, the soil pollution caused by improper fertilizer application is reduced, the biological environment is improved, and the radish yield and economic benefits are improved effectively.

Description

technical field [0001] The invention relates to a formula fertilization method for radish soil testing, in particular to a method for formula fertilization according to soil nutrients, and belongs to the technical field of agricultural fertilization. Background technique [0002] At present, the average annual fertilizer utilization rate in my country is only 30%, nitrogen fertilizer utilization rate is generally 30% to 50%, phosphorus fertilizer utilization rate is generally 10% to 15%, and potassium fertilizer utilization rate is generally 40% to 70%. There are many reasons for the low utilization rate of chemical fertilizers, among which the unreasonable amount and proportion of fertilizer application are the main factors. By carrying out soil testing and formulating fertilization, the amount of fertilization and the ratio of each nutrient element in the fertilizer can be reasonably determined, and the utilization rate of chemical fertilizers can be effectively improved. ...
