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 K326

Embodiment 1

[0021] The preparation method of special compound fertilizer for flue-cured tobacco variety K326: It is made by drum steam granulation process, that is, 14-16 parts of ammonium nitrate, 16-18 parts of diammonium phosphate, 47-49 parts of potassium sulfate and 50 parts of diatoms The soil is pre-crushed separately, then stirred and mixed, and then crushed into powder, and the mixed components are drum-granulated. The granulation process and conditions are as follows: add steam to the drum, and start with the powder of the mixed elemental fertilizer. It is advisable to reunite, and the roughly agglomerated powder is fed into the drying kiln for drying through the belt, and the temperature at the inlet 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 passed through After mesh sieving, the finished product is bagged, and the oversized or undersized particles are returned for further regranula...

Embodiment 2

[0024] The preparation method of the special compound fertilizer of flue-cured tobacco variety K326: same as embodiment one.

[0025] For medium-fertility fields (the grading standard is the second soil survey), when transplanting, apply fertilizers with a ratio of 8:8:24 of nitrogen, phosphorus, and potassium for preparation, and the application rate is 65kg / 667m 2 7 days after transplanting and 15 days after transplanting, apply potassium nitrate 6kg and 13kg respectively as topdressing for the first time, and apply potassium sulfate 19kg as topdressing for the second time 40 days after transplanting.

Embodiment 3

[0027] The preparation method of the special compound fertilizer of flue-cured tobacco variety K326: same as embodiment one.

[0028] For low-fertility fields (the grading standard is the second soil survey), when transplanting, apply fertilizers with a ratio of 8:10:32 of nitrogen, phosphorus, and potassium for preparation, and the application rate is 70kg / 667m 2 7 days after transplanting and 15 days after transplanting, apply potassium nitrate 6kg and 13kg respectively as topdressing for the first time, and apply potassium sulfate 19kg as topdressing for the second time 40 days after transplanting.

Abstract

The invention belongs to the technical field of agriculture, and particularly relates to a special compound fertilizer for flue-cured tobacco variety K326 and application thereof. The special compound fertilizer for flue-cured tobacco variety K326 contains 7.5-8.5% of nitrogen, 7.5-8.5% of phosphorus and 23-25% of potassium. When the compound fertilizer is used for planting the flue-cured tobacco variety K326, the tobacco plant has favorable integral growth vigor and high disease tolerance, and the incidence rate of black shank is lowered by 3.3-6.66%. Various agronomic character values are excellent, and the waist leaf length and width are respectively increased by 13.85-20.97% and 12.5-21.74%. The total nitrogen, nicotine, total sugar, reducing sugar, tobacco potassium, sugar / base ratio and nitrogen / base ratio of the tobacco are respectively within a proper range. The compound fertilizer can effectively enhance the appearance quality of the tobacco, increase the tobacco aroma and potassium content, improve the taste of the tobacco and enhance the yield and quality of the tobacco, and is applicable to batch planting of the flue-cured tobacco variety K326.

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 K326 and its application. Background technique [0002] The flue-cured tobacco variety K326 was bred by the American Northup King Seed Company (Northup King Seed Company) by crossing McNair225 (McNair30×NC95). The promotion variety participated in the national regional test of flue-cured tobacco varieties from 1986 to 1988. In 1989, it was approved as a national promotion variety by the National Tobacco Variety Approval Committee. The yield per mu of flue-cured tobacco variety K326 is 165.51-202.53kg. Raw tobacco is orange-yellow, rich in oil, strong in luster, loose in leaf structure, moderate in identity, main tendon ratio 28.97%; total sugar 26.38%, nicotine 2.01-3%, protein 10.77%, total nitrogen 2.07%, Shimu grams value 2.45, Nitrogen / Alkali 1.03, Sugar / Alkali 13.12; The aroma is good, the aroma i...
