Embodiment 1

[0025] A tobacco nutrient soil consisting of raw materials of the following qualities:

[0026] Field soil 500kg, tobacco-specific compound fertilizer 2.5kg, calcium magnesium phosphate fertilizer 15kg, decomposed vegetable dry cake 10kg, dolomite powder 25kg, ammonium molybdate 50g; the mass ratio of nitrogen, phosphorus pentoxide and potassium oxide in the tobacco-specific compound fertilizer is 8 :6:20, the sum of the mass content of nitrogen, phosphorus and potassium is 45%, wherein the effective mass content of phosphorus pentoxide in calcium magnesium phosphate fertilizer is 18%, the effective mass content of calcium oxide is 45%, and the effective mass content of magnesium oxide The mass content is 12%.

[0027] The present embodiment also provides the preparation method of above-mentioned tobacco nutrient soil, and concrete steps are:

[0028] S1. Take the field soil where the previous crops are non-Solanaceae crops, dry, arrange, and remove plant residues and polluta...

Embodiment 2

[0034] A kind of tobacco nutrient soil, is made up of the raw material of following quality:

[0035] Field soil 500kg, tobacco compound fertilizer 2.5kg, calcium magnesium phosphate fertilizer 15kg, decomposed vegetable withered cake 10kg, dolomite powder 50kg, ammonium molybdate 50g; Wherein the mass ratio of nitrogen, phosphorus pentoxide and potassium oxide in the special compound fertilizer for tobacco is 12: 10:20, the sum of the mass content of nitrogen, phosphorus and potassium is 50%, wherein the effective mass content of phosphorus pentoxide in calcium magnesium phosphate fertilizer is 20%, the effective mass content of calcium oxide is 48%, and the effective mass content of magnesium oxide The content is 15%.

[0036] The preparation method of this example is the same as that of Example 1, except that the moisture content of the soil after mixing in S3 is 60%, and the compost retting and fermentation at room temperature is carried out for 20 days in S4.

Embodiment 3

[0038] A kind of tobacco nutrient soil, is made up of the raw material of following quality:

[0039] Field soil 500kg, tobacco compound fertilizer 5kg, calcium magnesium phosphate fertilizer 15kg, decomposed vegetable dry cake 10kg, dolomite powder 50kg, ammonium molybdate 50g; the mass ratio of nitrogen, phosphorus pentoxide and potassium oxide in the tobacco special compound fertilizer is 10:8 : 20, the sum of the mass content of nitrogen, phosphorus and potassium is 48%, wherein the effective mass content of phosphorus pentoxide in the calcium magnesium phosphate fertilizer is 18%, the effective mass content of calcium oxide is 45%, and the effective mass content of magnesium oxide 12%.

[0040] The preparation method of this example is the same as that of Example 1, except that the water content of the soil after mixing in S3 is 70%, and the composting and retting fermentation at room temperature is carried out for 25 days in S4.

Abstract

The invention provides tobacco nutrient soil and a preparation method thereof. The soil is prepared from the following raw materials in parts by mass: 500 parts of field soil, 2.5 parts of tobacco compound fertilizer, 15 parts of calcium magnesium phosphate fertilizer, 10 parts of decomposed rapeseed dreg cake, 25 parts of dolomite powder and 0.05 parts of ammonium molybdate. The preparation method of the tobacco nutrient soil comprises the following steps: crushing and sieving the field soil, mixing and uniformly stirring the field soil with the tobacco compound fertilizer, the calcium magnesium phosphate fertilizer, the decomposed rapeseed dreg cake and the dolomite powder, adjusting the water content of the mixed soil to 60%-70%, and performing pile fermentation for 20-30 days to obtainthe tobacco nutrient soil. The tobacco nutrient soil is prepared by fermentation, soil disinfection is not required, and the problems that existing nutrient soil needs methyl bromide fumigated disinfection and the disinfection process is complex and harmful are effectively solved; moreover, the fermentation process is simple to operate and easy to implement, the problem of poor use effect causedby individual preparation by tobacco farmers is effectively solved by means of the tobacco nutrient soil, and higher practical significance is achieved.

Description

technical field [0001] The invention relates to the technical field of tobacco cultivation, in particular to a tobacco nutrient soil and a preparation method thereof. Background technique [0002] Tobacco seedlings use a relatively large amount of humus soil. At present, the production mainly uses humus soil (mountain soil) from broad-leaved forests. About 0.086m2 of mountain soil is needed to supply one mu of flue-cured tobacco seedlings 3 . Generally, the thickness of the mountain skin is about 2.5cm, and it takes 20 to 30 years to form. The water absorption capacity of mountain soil can reach 2 to 4 times of its own weight, and its function can reduce surface runoff. The consequence of clogging the mountain's skin and soil is that the water storage capacity of the mountain body is reduced. If things go on like this, the surface runoff will increase, which will inevitably lead to soil erosion and ecological imbalance. At present, peat soil is also used to raise seedlin...
