A Quick Method of Fertilizing the Yellow Soil Tobacco Field

Abstract

The invention belongs to the technical field of soil improvement, and particularly relates to a rapid fertilization method for a newly-prepared yellow soil tobacco field. Through the steps of basal application and improvement of farm manure, alternate layout arrangement of wide ridges and narrow ridges, combination of the narrow ridges and the wide ridges to conduct organic fertilizer fertilization, green manure fertilization, straw mulching fertilization and the like, a technology which is low in cost and easy to control is provided, agricultural application and ripening fertilization of yellow soil are organically combined together, normal production of farmers is not affected, the farmers can learn and understand the technology easily, operation is convenient, and land utilization and maintaining are truly and organically unified. By the adoption of the method, soil ripening fertilization work can be completed in three years altogether, the production operation of tobacco growers can be conducted continuously, and certain economic incomes of the tobacco growers can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a rapid fertilization method for freshly finishing yellow soil tobacco fields. Background technique [0002] Yellow soil is a zonal soil formed under humid subtropical climate and bioclimatic conditions. The soil texture is mostly loamy, with good permeability and fertilizer supply. It is suitable for planting flue-cured tobacco. The distribution area of ​​yellow soil in tobacco-growing areas in my country is 15 million hectares. Mainly distributed in Sichuan, Guizhou and other provinces, it is the main tobacco-growing soil type in southern mountainous areas. However, its topography is complex, the fields are fragmented, the slope is large, and the cultivated land is relatively scattered. In some rocky desertification areas, the proportion of rocks in the cultivated land is relatively large, the cultivated land is relatively scattered, and the continuous plant...

Problems solved by technology

The soil fertility and quality of the newly adjusted tobacco fields are poor, with low organic matter and C / N value, lack of available nutrients such as phosphorus and potassium in the soil, reduced soil microbial activity, thin soil layer, soil aggregate structure, poor water and fertilizer retention, and poor drought resistance. , the soil fertility and productivity of the new tobacco fields are extremely low, which greatly affects the yield and quality of tobacco

[0004] There are many cultivation measures and methods in flue-cured tobacco production, such as Chinese patent CN200810069035.5 discloses a kind of flue-cured tobacco concave-shaped double ridge full growth period plastic film covering cultivation technology, the main functions are water collection, water retention and solving seasonal drought in tobacco field, but The current ridging machine cannot be used to raise the ridges, and manual ridges must be used to increase the workload of the tobacco farmers; Chinese patent CN200910102852.0 discloses a method for the dislocation cultivation of flue-cured tobacco in one ridge and two rows, which is mainly aimed at improving the quality of tobacco leaves and highlighting the characteristics of tobacco leaf divisions. Make full use of the land resources in the tobacco area without improving the soil; Chinese patent CN101897252B discloses a method for rapid thickening and maturation of purple newly improved soil in the Three Gorges reservoir area. At the same time, the improvement of flue-cured tobacco fertilization needs to take into account the quality of tobacco leaves. Tobacco field fertilization requires excessive nutrient input. Excessive nutrient input leads to green and late maturity of tobacco leaves, difficulty in curing and poor quality of tobacco leaves. Tobacco field improvement especially needs to take into account both soil fertilization and Synergistic improvement of tobacco leaf production and quality
