[0003] 1. Empirical fertilization method: farmers determine the amount of fertilization according to their own experience. The disadvantage of this method is that it does not consider the basic conditions of the soil and the amount of fertilizer required by crops, which may easily lead to excessive or insufficient fertilization.
Only a few county (city) soil and fertilizer stations in the country carry out this business, and most county (city) soil and fertilizer stations cannot carry out this business due to reasons such as funds, personnel, venues, and equipment

Abstract

A method for recommending the quantity of applied fertilizer features that according to the known planting information of a particular field region, including the parameters associated to the crops and fertilizers, the balanced values of N, P and K nutrients in unit area for the crops planted in plan are found out and recommended. Its advantages are eary operation and popularization and low cost.

Description

Technical field: [0001] The invention belongs to the technical field of crop fertilization, in particular to a method for recommending the amount of fertilizer applied to crops. Background technique: [0002] At present, the main methods recommended for crop fertilizer application are: [0003] 1. Empirical fertilization method: farmers determine the amount of fertilization according to their own experience. The disadvantage of this method is that it does not consider the basic conditions of the soil and the amount of fertilizer required by crops, which may easily lead to excessive or insufficient fertilization. [0004] 2. Soil fertility index method: According to the measured soil effective nutrients, the soil effective nutrient fertility index is verified with the biological relative index, and the corresponding grading range value is determined. At the same time, experiments on the amount of fertilizer applied were set up on fields with different nutrient fertility inde...
