Embodiment 1

[0015] Multivariate fertilizer for tobacco: by weight, 12.6 parts of urea, 9.8 parts of diamine phosphate, 39.8 parts of potassium sulfate, 18.0 parts of bone meal, 6.8 parts of humic acid, 1.8 parts of rare earth, 1.7 parts of magnesium and 1.8 parts of sulfur and trace elements The elements boron 0.2 part, iron 0.2 part, zinc 0.2 part, manganese 0.1 part, copper 0.25 part and molybdenum 0.25 part. Wherein the calcium of multivariate tobacco special fertilizer exists in bone meal, and its calcium content is usually 25-30%.

[0016] Preparation method: by weight, 12.6 parts of urea, 9.8 parts of diamine phosphate, 39.8 parts of potassium sulfate, 1.7 parts of magnesium and 1.8 parts of sulfur, 0.2 parts of boron, 0.2 parts of iron, 0.2 parts of zinc and 0.1 parts of manganese 0.25 parts of copper and 0.25 parts of molybdenum are mixed and crushed to 30 meshes, then mixed with 6.8 parts of humic acid, 8 parts of rare earths crushed to 30 meshes and 18.0 parts of acidified bone ...

Embodiment 2

[0020] The difference from Example 1 is:

[0021] Multivariate fertilizer for tobacco: by weight, 13 parts of urea, 10.2 parts of diamine phosphate, 40.2 parts of potassium sulfate, 22.0 parts of bone meal, 7.2 parts of humic acid, 2.2 parts of rare earth, 1.7 parts of magnesium and 2 parts of sulfur and trace elements The elements boron 0.1 part, iron 0.1 part, zinc 0.1 part, manganese 0.1 part, copper 0.25 part and molybdenum 0.25 part.

[0022] Preparation method: in parts by weight, 13 parts of urea, 10.2 parts of diamine phosphate, 40.2 parts of potassium sulfate, 3.7 parts of medium elements of magnesium and sulfur, and 0.9 parts of trace elements of boron, iron, zinc, manganese, copper and molybdenum After mixing, grind to 40 meshes, mix with 7.2 parts of humic acid, 2.2 parts of crushed 40 meshes of rare earth and 22 parts of acidified bone meal, and then granulate by traditional method.

[0023] The humic acid is obtained by pulverizing the lignite into 40 meshes, ad...

Embodiment 3

[0026] The difference from Example 1 is:

[0027] Multivariate fertilizer for tobacco: by weight, 12.8 parts of urea, 10 parts of diamine phosphate, 40 parts of potassium sulfate, 20 parts of bone meal, 7 parts of humic acid, 2 parts of rare earth, 2.1 parts of middle element magnesium and 1.8 parts of sulfur and Trace elements boron 0.1 part, iron 0.1 part, zinc 0.1 part, manganese 0.1 part, copper 0.2 part and molybdenum 0.2 part.

[0028] Preparation method: in parts by weight, 12.8 parts of urea, 10 parts of diamine phosphate, 40 parts of potassium sulfate, 3.9 parts of medium elements and 0.8 parts of trace elements are mixed and pulverized to 35 meshes, then mixed with 7 parts of humic acid and crushed for 35 Mix 2 parts of target rare earth with 20 parts of acidified bone powder and granulate by traditional method.

[0029] The humic acid is obtained by pulverizing lignite into 35 meshes, adding ammonium water with a mass content of 13%, and mixing them, then stacking ...

Abstract

The invention relates to a technique of a fertilizer for cultivating a cured tobacco, in particular to a fertilizer special for a multi-element tobacco and a preparation method thereof. The special fertilizer comprises the following components in portion by weight: 12.6 to 13.0 portions of urea, 9.8 to 10.2 portions of diamine phosphate, 39.8 to 40.2 portions of potassium sulfate, 18.0 to 22.0 portions of bone powder, 6.8 to 7.2 portions of humic acid, 1.8 to 2.2 portions of rare earth, 3.5 to 3.9 portions of medium element, and 0.8 to 1.2 portions of microelement. The fertilizer special for the multi-element tobacco uses the rear earth and the humic acid as main bodies, belongs to nutrient fertilizers, and can greatly improve the integral level of a tobacco field, improve the yield and the quality of crops, stimulate the growth of the crops, improve the disease resistance of the crops, prolong the release cycle of the fertilizer, reduce the fertilizer loss, improve the stress resistance of the crops, and provide a large amount of organic matters for soil to play a role of improving the soil.

Description

technical field [0001] The invention relates to the technology of fertilizer for flue-cured tobacco cultivation, in particular to a special multi-component fertilizer for tobacco and a preparation method thereof. Background technique [0002] With the development of agricultural production, the tobacco industry has more and more requirements for fertilizers, and the requirements for the quality of fertilizers are getting higher and higher. Single storage of chemical fertilizers can increase agricultural production, but long-term use can cause soil compaction, severely damage the soil aggregate structure, and obviously reduce the quality of crop products, and more importantly, seriously pollute the ecological environment. The Japanese government has made it clear that it will greatly reduce the production and use of chemical fertilizers. The Beijing Municipal Government has decided to thoroughly clean up Beijing's agricultural pollution starting in 2001. At the same time, a...
