Problems solved by technology

At present, in the traditional planting mode, due to the lack of scientific guidance, the tobacco farmers have unreasonable fertilizer types and nutrient distribution ratios in production. Some farmers still use urea on flue-cured tobacco, excessive nitrogen application, and insufficient potassium application. Wait
Tobacco farmers use chemical fertilizers blindly, and the unreasonable nutrient ratio not only reduces the utilization rate of fertilizers, increases fertilizer costs, but also adversely affects the yield and quality of tobacco leaves. What is more serious is that excessive chemical fertilizers have adverse consequences on the environment
It is understood that tobacco companies around the world have special nitrogen, phosphorus and potassium compound fertilizers for flue-cured tobacco, but there is no specific nitrogen, phosphorus and potassium compound fertilizer for flue-cured tobacco variety NC102

Embodiment 1

[0020] The preparation method of the special compound fertilizer for flue-cured tobacco variety NC102: it is made by drum steam granulation process, that is, 11 parts of ammonium nitrate, 13 parts of diammonium phosphate, 38 parts of potassium sulfate and 38 parts of diatomaceous earth are pre-crushed respectively, and then Stir and mix, then break into powder, and drum granulate the mixed components. The granulation process and conditions are as follows: steam is added to the drum, and it is advisable to start agglomeration of the mixed elemental fertilizer powder, which will be roughly The agglomerated powder is fed into the drying kiln for drying through the belt, and the inlet temperature of the drying kiln is controlled at 140°C. The powder is further granulated and dried in the drying kiln, cooled by the cooling kiln, and the finished product is packed after passing through a 5-mesh sieve. Bags, oversized or undersized granules are returned for further re-granulation. Th...

Abstract

The invention belongs to the technical field of agriculture, and discloses a compound fertilizer special for a flue-cured tobacco variety NC102. In the compound fertilizer, the weight ratio of nitrogen to phosphorus to potassium is (6-7):(6-7):(18.5-20.5), nitrogen comes from ammonium nitrate, phosphorus comes from diammonium phosphate, and potassium comes from potassium sulphate. The compound fertilizer is specifically prepared from 12 parts of ammonium nitrate, 14 parts of diammonium phosphate and 39 parts of potassium sulphate. The compound fertilizer can enhance the disease resistance of plants, improve the yield and quality of flue-cured tobaccos and be applied to batch planting of the flue-cured tobacco variety NC102.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a special compound fertilizer for flue-cured tobacco variety NC102. Background technique [0002] The flue-cured tobacco variety NC102 passed the US regional minimum standard program test in 2001, passed the North Carolina official variety test from 2002 to 2004, and was recommended by the North Carolina official test planting in 2004. The F1 generation hybrid registered by F.W.Richard Seed Company of the United States, distributed by Goldleafseed Company of the United States, was introduced to Yunnan Province by Yunnan China Tobacco Industry Company and Yunnan Tobacco Company for trial planting in 2006 and was successfully planted. The yield per mu of flue-cured tobacco variety NC102 is about 145kg. [0003] In recent years, with the rapid development of flue-cured tobacco production, some problems have become increasingly prominent, such as low scale, single va...
