Problems solved by technology

[0003] The application of the existing soil testing and formula fertilization is limited, often due to excessive application of chemical fertilizers, the local soil is severely compacted, the environment is polluted, and the utilization rate of fertilizers is low. Therefore, we design a method of soil testing and formula fertilization

Embodiment Construction

[0017] The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them; based on the embodiments of the present invention, those of ordinary skill in the art All other embodiments obtained under the premise of no creative work belong to the protection scope of the present invention.

[0018] The invention discloses a method for soil testing formula fertilization. The specific steps are as follows: A. Before sampling, the area fertilized by the soil testing formula is divided into a plurality of sampling units, and sufficient sampling should be ensured in each sampling unit area when sampling point, so that it can represent the soil characteristics of the sampling unit. Specifically, sampling is completed through a sampler tool. After sampling, the collected soil is naturally air-dried and stored. During the air-drying process,...

Abstract

The invention discloses a soil testing formulated fertilization method. The method comprises the following steps of before sampling, equally dividing a soil testing formulated fertilization area intoa plurality of sampling units, collecting a soil sample by adopting the units, and carrying out air drying treatment; enabling the collected soil sample to be crushed, rolled and screened, and carrying out pH value, salinity, exchange performance, available nutrient item, organic matter, total nitrogen and calcium carbonate measuring; inputting a sampling information record and measured data valueinformation into a microcomputer, and establishing a database; according to the crop fertilizer demand, the soil fertilizer supply amount and the in-season utilization rate of different fertilizer inthe sampling unit area, selecting the fertilizer ratio and the fertilization amount in the sampling unit area through a nutrient balance method; and determining a fertilization period and the proportion of base fertilizer to additional fertilizer in the total fertilization amount according to the tillage system rule of the sampling unit area. By adopting the technical scheme, the fertilizer can be saved, the soil fertility can be increased, the soil pollution caused by improper fertilization can be reduced, and the soil health can be maintained.

Description

technical field [0001] The invention relates to the technical field of soil testing formula, in particular to a soil testing formula fertilization method. Background technique [0002] Soil testing formula fertilization is based on soil test and fertilizer field test, according to the law of crop fertilizer demand, soil fertilizer supply performance and fertilizer effect, and on the basis of rational application of organic fertilizers, it proposes nitrogen, phosphorus, potassium and medium and trace elements, etc. Fertilizer application amount, fertilization period and application method. In layman's terms, it is scientific application of formula fertilizer under the guidance of relevant basic agricultural theories. The core of soil testing and formula fertilization technology is to adjust and solve the contradiction between crop fertilizer demand and soil fertilizer supply. At the same time, it supplements the nutrient elements required by crops in a targeted manner, real...
