Embodiment 1

[0027] For soil with low fertility (about 37 mg / kg of soil alkaline nitrogen, about 7 mg / kg of soil available phosphorus, and about 55 mg / kg of soil available potassium), a ratio of 14:11:22 of nitrogen, phosphorus, and potassium can be used. The recommended application rate is 100kg / 667m 2 . The percentage by weight of each component of this special fertilizer for burley tobacco is:

[0028] Ammonium nitrate: 29%, diammonium phosphate: 24%, potassium sulfate 44%, magnesium sulfate 3%, add 3% filler.

[0029] The preparation method of special fertilizer for burley tobacco in this embodiment is made by drum steam granulation process, that is, each component is pre-crushed separately, then stirred and mixed, and then crushed into powder, and the mixed components are drum-made The granulation process and conditions are as follows: add an appropriate amount of steam to the drum, and it is advisable to start the agglomeration of the powders of the mixed elemental fertilizers. The...

Embodiment 2

[0031] For moderately fertile soil (86 mg / kg of soil alkaline nitrogen, 14 mg / kg of soil available phosphorus, and 115 mg / kg of soil available potassium), the ratio of 13:10:22 of nitrogen, phosphorus, and potassium can be used. The recommended application rate is 85kg / 667m 2 . The percentage by weight of each component of this special fertilizer for burley tobacco is:

[0032] The preparation method of the special fertilizer for Burley tobacco of this example is the same as in Example 1.

[0033] Ammonium nitrate: 27.12%, diammonium phosphate: 22.22%, potassium sulfate 44%, magnesium sulfate 6.66%, add 2% filler.

Embodiment 3

[0035] For high-fertility soil (soil alkaline nitrogen 137mg / kg, soil available phosphorus 31mg / kg, soil available potassium 165 mg / kg), the ratio of nitrogen, phosphorus and potassium 13:9:20 can be used. Recommended application rate 70kg / 667m 2 . The percentage by weight of each component of this special fertilizer for burley tobacco is:

[0036] Ammonium nitrate: 28.23%, diammonium phosphate: 20%, potassium sulfate 40%, magnesium sulfate 11.77%, add 3% filler.

[0037] The preparation method of the special fertilizer for Burley tobacco of this example is the same as in Example 1.

[0038] The special compound fertilizer for burley tobacco can also be made by ordinary mixing of various components, or it can be made by a general spraying granulation process.

[0039]The tested variety Dabai No. 1, the soil is paddy soil, and the harvesting method is half cutting. In order to test the fertilizer effect corresponding to the relationship of soil fertility, a pair of proporti...

Abstract

The invention discloses a compound fertilizer special for producing burley tobacco, which comprises simple substance fertilizers such as ammonium nitrate, diammonium phosphate, potassium sulfate and magnesium sulfate. The compound fertilizer special for the burley tobacco has the advantages that: the premature of the burley tobacco can be obviously promoted, nutrition is more balanced, the compound fertilizer is easily absorbed by the burley tobacco, tobacco leaves are better matured and more regular and consistent, harvest time can be shortened, chemical components in the tobacco leaves are high in harmony, and the like.

Description

technical field [0001] The invention relates to a compound fertilizer applied as a base fertilizer, in particular to a special compound fertilizer used for the production of burley tobacco. Background technique [0002] During the growth and cultivation of Burley tobacco, compound fertilizers are required, and the main nutrients of compound fertilizers used as base fertilizers are nitrogen, phosphorus and potassium. Compared with flue-cured tobacco, burley tobacco requires a large amount of fertilizer. In the traditional planting mode, due to the lack of scientific guidance, tobacco farmers use excessive nitrogen fertilizer in the base fertilizer in pursuit of high yield, ignoring the combined application of other nutrients, so that the nitrogen in the tobacco field , phosphorus, and potassium nutrient content imbalance, which will not only cause the chemical composition in the tobacco leaves to be uncoordinated, especially the high nicotine content and low nitrogen-alkaline...
