Abstract

The invention discloses a special fertilizer for tobacco and its preparation method and application. The mass percentage of inorganic components in the slow-release fertilizer is 60-75%; the content of N element in the inorganic components is 8-11%. 2 o 5 The content of element P is 4-9%, and the content of K is 2 The content of K element in O is 14-18%; the phosphate fertilizer is composed of ammonium polyphosphate and monoammonium phosphate with a mass ratio of 1:3-4; the organic component is composed of lignin and ammonium phosphate with a mass ratio of 1:3-6 Composed of decomposed silkworm excrement. In the present invention, decomposed silkworm excrement and lignin in a specific proportion are used as organic components, ammonium polyphosphate and monoammonium phosphate in a specific proportion are used as phosphate fertilizers, and a specific amount of inorganic fertilizer is used, so that the tobacco special fertilizer obtained can be effective in growing tobacco. Promoting the early emergence of slow seedlings and strong seedlings is helpful to appropriately accelerate the growth process, prolong the accumulation time of dry matter, and is conducive to the formation of yield and quality.

Description

technical field

[0001] The invention relates to the technical field of fertilizer application, in particular to a special fertilizer for tobacco and its preparation method and application. Background technique

[0002] Every year, my country's tobacco planting area is stable at more than 10 million mu, and the economic value of tobacco is relatively high; however, there is still a lot of room for improvement in tobacco production in terms of rational use of fertilizers and improvement of tobacco leaf quality.

[0003] At present, the main problems of tobacco production are as follows:

[0004] (1) Excessive emphasis on the use of nitrate nitrogen and potassium input, and both nitrate nitrogen and potassium ions are relatively easy to lose, making fertilizer use efficiency low. At the same time, the excessive input of potassium can easily cause the imbalance of soil nutrients, which is not conducive to the absorption of medium and trace elements by tobacco.

[0005] (2) In ...

Examples

Embodiment 1

[0043] (1) Special fertilizer for tobacco:

[0044] It consists of the following raw materials in parts by mass, 10 parts of urea, 8 parts of monoammonium phosphate, 2 parts of ammonium polyphosphate, 17 parts of potassium sulfate, 14 parts of potassium nitrate, 6 parts of magnesium nitrate hexahydrate, 14 parts of attapulgite, lignin 5 parts, 24 parts of decomposed silkworm excrement.

[0045] Each component is mixed according to the above mass parts, and then granulated by a drum, dried, cooled, and sieved to obtain a finished product.
