Problems solved by technology

[0004] 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 the 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
(3) The measurement of soil samples takes a long time
The nutritional diagnosis method needs to measure the nutrient content of a certain part of the plant, and there are also disadvantages such as few sampling stations and high cost. On the other hand, remedial fertilization measures are often taken after the plants show a lack of nutrients
[0014] In addition, the Chinese authorized patent CN1010544B discloses a fertilization method, in which the fertilizer effect equation needs to be established, which makes the method too complicated, and it is difficult for ordinary farmers to use this method in production practice

Embodiment Construction

[0083] An intelligent tool to guide scientific fertilization, the hardware used is the iPAQ3600 portable computer (PDA) produced by Compaq Computer Corp.; the screen is an input and output device, and the upper half of the screen can prompt the user to input plot parameters and display calculation results , the lower part can be used to input plot parameters with a stylus; this type of PDA has its own internal hard disk as a storage device, and non-plot parameters are stored in it through SQL Sever database files; CPU is a computing control device, and the computing program is through the Pocket PC system Under the C language development, stored in the hard disk, and through the CPU to control the operation of the program.

[0084] The farmer inputs the plot parameters through the input device, and the operation control device uses the calculation program to call the relevant non-plot parameters of the area according to the input plot parameters, and calculate the nutrient bala...

Abstract

An intelligent tool for guiding the scientific application of fertilizer is composed of an input device for recording the different parameters for different field blocks in a field area, a storage unit for storing the operating program and the parameters independent to the field blocks in a field area, an operating and controlling unit for calculating the balanced values of N, P and K in unit area and determining the recommended values of N, P and K nutrients and an output device for outputting said recommended values.

Description

Technical field: [0001] The invention relates to a calculating device, in particular to a calculating tool for calculating scientific fertilization amount by inputting certain parameters. [0002] The device of the present invention adopts "a method for recommending the amount of fertilizer applied to crops" filed by the applicant on the same day. Background technique: [0003] At present, the main methods recommended for crop fertilizer application are: [0004] 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. [0005] 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 cor...
