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 the production of flue-cured tobacco. For example, Chinese patent CN200810069035.5 discloses a cultivation technique for flue-cured tobacco with concave double ridges and plastic film covering during the whole growth period. The function is to collect water, keep water and solve the seasonal drought in the tobacco field, but the current ridging machine cannot be used to rid the ridges, and manual ridges must be used to increase the workload of tobacco farmers; T...

Embodiment 1

[0035] Example 1 A method for rapid fertilization aimed at newly finishing yellow soil tobacco fields, the steps of which are as follows:

[0036] (1) Basic application of farmyard manure: evenly spread farmyard manure in the newly sorted tobacco field, and the amount of spreading is 300 kg / 666.7m 2 , and use a rotary tiller to plow into the 0-20 cm plow layer.

[0037] Described farmyard manure is made by following steps:

[0038] Prepare the following raw materials in parts by weight: 300 parts of manure without tobacco plant residues, 100 parts of corn or sweet potato straw, 50 parts of tobacco soil, 20 parts of bentonite, 10 parts of calcium magnesium phosphate fertilizer, 100 parts of rice husk biochar, humic acid 50 parts of ammonium, broad-spectrum insecticide-0.2 part of emamectin benzoate, 5 parts of bacterial material, 1 part of borax, 2 parts of zinc sulfate and 2 parts of magnesium sulfate; Described calcium magnesium phosphate fertilizer consists of the follo...

[0050] Example 2 A method for rapid fertilization aimed at newly finishing yellow soil tobacco fields, the steps of which are as follows:

[0051] (1) Basic application of farmyard manure: evenly spread farmyard manure in the newly arranged tobacco field, and the amount of spreading is 500 kg / 666.7m 2 , and use a rotary tiller to plow into the 0-20 cm plow layer;

[0052] (2) Ridging: After 30 days of overturning and pressing of the farmyard manure base, the strips of tobacco N, P 2 o 5 、K 2 The amount of compound fertilizer with O nutrient ratio of 8-12-25 is 55 kg / 666.7m 2 , followed by ridges on the basis of strip-applied compound fertilizers, changing the tradition of tobacco farmers ridges at equal intervals of 1.1 meters, and setting up alternate layouts of wide and narrow ridges, with a row spacing of 120 cm for wide ridges and 100 cm for narrow ridges. The bottom of the ridge is 60cm wide and 30cm high, and the ridge is completed by laying plastic film on the rid...

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...
