Problems solved by technology

Flue-cured tobacco is an economic crop that pays equal attention to both yield and quality, especially quality. In the current production of flue-cured tobacco in Yuxi, farmers blindly pursue yield and apply nitrogen fertilizers. This not only fails to make full use of the nutrient supply capacity of the soil itself, but also causes a large amount of nutrients to be applied to fertilizers. Loss, causing varying degrees of pollution to water, soil and the atmosphere, but excessive fertilizer input did not improve the quality of tobacco leaves

Embodiment 1

[0012] Embodiment 1: adopt the formula of the present invention to carry out test

[0013] The formula of base fertilizer in this implementation is: N-P 2 O 5 -K 2 O 14-8-24

[0014] The compounding method of the base fertilizer is: 24 parts of urea, 19.2 parts of diammonium phosphate, 45 parts of potassium sulfate, 0.6 parts of anhydrous borax, 1.2 parts of magnesium sulfate, 0.7 parts of zinc sulfate, 7.3 parts of potassium humate, and 2 parts of chitin; The above components are added to the diammonium phosphate process device and fully mixed to obtain the compound fertilizer of this formula.

[0015] 1 mu of experimental land was selected, and the main local variety Yun 97 was selected as the experimental variety. Before transplanting tobacco seedlings, apply 20kg / mu of base fertilizer (mixed pond); tobacco special fertilizer (12-4-31) is applied in 10 days after transplanting and cultivating soil mixed with water, and the application amount is 5kg / Mu, 10kg / mu.

Embodiment 2

[0016] Embodiment 2: adopt the formula of the present invention to carry out test

[0017] The formula of base fertilizer in this implementation is: N-P 2 O 5 -K 2 O 14-10-22

[0018] The method of formulating the base fertilizer is: 22.6 parts of urea, 24 parts of diammonium phosphate, 42 parts of potassium sulfate, 0.6 parts of anhydrous borax, 1.2 parts of magnesium sulfate, 0.7 parts of zinc sulfate, 7.3 parts of potassium humate, and 2 parts of chitin; The above components are added to the diammonium phosphate process device and fully mixed to obtain the compound fertilizer of this formula.

[0019] 1 mu of experimental land was selected, and the main local variety Yun 97 was selected as the experimental variety. Before transplanting tobacco seedlings, apply 20kg / mu of base fertilizer (mixed pond); tobacco special fertilizer (12-4-31) is applied in 10 days after transplanting and cultivating soil mixed with water, and the application amount is 5kg / Mu, 10kg / mu.

Abstract

The invention provides a base fertilizer formula special for Yunnan flue-cured tobacco production, which comprises the following components in parts by mass: 21-25 parts of urea, 19-24 parts of diammonium phosphate, 42-48 parts of potassium sulfate, 0.5-1 part of anhydrous borax, 1-2 parts of magnesium sulfate, 0.5-1 part of zinc sulfate, 7-10 parts of potassium humate and 0.5-1 part of soil conditioner, wherein the ratio of N-P2O5-K2O in the base fertilizer is (13-16): (6-8): (24-28), the content of nitrate nitrogen is 46.3%-51.8%, the content of water-soluble phosphorus is 87.3%-91.2%, the content of humic acid is greater than or equal to 4%, the content of a soil conditioner and magnesium is greater than or equal to 2%, boron is greater than or equal to 1%, and zinc is greater than 1%.According to the base fertilizer formula, one-time topdressing can be reduced in actual production, the flue-cured tobacco resistance is improved, the dosage and the pesticide use frequency are reduced, and labor and time are saved. The invention further provides a fertilizer preparation method of the base fertilizer formula.

Description

technical field [0001] The invention relates to a fertilizer for tobacco planting, in particular to a formula, a preparation method and a fertilizer compounding method for a special base fertilizer for the production of Yunyan flue-cured tobacco. Background technique [0002] Yuxi is located in the central part of Yunnan Province, with geographical coordinates ranging from 23°19' to 24°53'N and 101°16' to 103°9'E. With unique geographical and climatic resources, it is an important tobacco area in Yunnan Province and the largest high-quality raw material of Hongta Group. core base. The development of Yuxi Tobacco directly affects the development of Hongta Group's high-end cigarette brands. Therefore, it is of great significance to carry out research on the production of green and ecological high-quality tobacco leaves in Yuxi Tobacco Area to improve the quality and safety of tobacco leaves in order to maintain the sustainable and healthy development of tobacco production in Y...
