Method for controlling quantity of flue-cured tobacco fertilization in mountain tobacco area

Abstract

The invention provides a mountain tobacco area flue-cured tobacco fertilization quantity control method which comprises the following steps: acquiring tobacco field distribution conditions, and collecting soil samples of a tobacco field soil cultivation area; using quantity data of different types of fertilizers in the tobacco field distribution area is collected, the using amount of N, P and K is calculated, and fertilization data is obtained; current-year flue-cured tobacco sales economic character data in different areas are acquired through flue-cured tobacco purchasing system data; the method comprises the following steps: sampling and collecting a soil sample in a tobacco field, and carrying out quantitative analysis on six indexes of pH value, organic matters, total nitrogen, alkali-hydrolyzable nitrogen, available phosphorus and quick-acting potassium in the sample to form soil nutrient and nutritional ingredient data; a database is established based on soil nutrient and nutritional ingredient data, fertilization data and tobacco economic character data, and a fertilization amount formula is fitted through the database. By analyzing nutritional ingredients and physical and chemical properties of different land parcels and aiming at the land parcels in different areas, a fertilization quantity control model is constructed, and an effective means of fertilization differentiation management is established.

Description

technical field [0001] The invention relates to the technical field of flue-cured tobacco fertilization, in particular to a method for controlling the quantity of flue-cured tobacco fertilization in mountain tobacco areas. Background technique [0002] In the traditional field management process of flue-cured tobacco, combined with the growth and physiological characteristics of flue-cured tobacco, different methods are used to apply corresponding types of fertilizers according to a certain amount in different periods to meet the field fertilizer demand of flue-cured tobacco, realize the matching between the physiological growth of flue-cured tobacco and the industrial availability of flue-cured tobacco, and complete the field industrial maturity. , to protect the economic value of flue-cured tobacco. [0003] In actual planting, there are scattered tobacco fields with large altitude spans, large differences in tobacco field types, and certain differences in soil texture, nu...
