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. The unreasonable nutrient distribution not only reduces the fertilizer utilization rate, increases the fertilizer cost, but also adversely

Embodiment 1

[0014] For high-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 40kg / 667m 2 , 7 days after transplanting and 15 days after transplanting, apply potassium nitrate 3kg and 7kg respectively as topdressing for the first time, and apply potassium sulfate 10kg as topdressing for the second time 40 days after transplanting.

[0015] Fertilizer preparation method: It 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-granulated. The granulation process and conditions In order to add an appropriate amount of steam to the drum, it is advisable to start the agglomeration of the mixed elemental fertilizer powder. The roughly agglomerated powder is fed into the drying kiln through the belt for drying...

Embodiment 2

[0017] For medium-fertility fields (the grading standard is the second soil survey), when transplanting, apply fertilizers with a ratio of nitrogen, phosphorus and potassium of 8:10:32 for preparation, and the application rate is 45kg / 667m 2 , 7 days after transplanting and 15 days after transplanting, apply potassium nitrate 3kg and 7kg respectively as topdressing for the first time, and apply potassium sulfate 10kg as topdressing for the second time 40 days after transplanting.

[0018] Fertilizer preparation method: with embodiment one.

Embodiment 3

[0020] 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 50kg / 667m 2 , 7 days after transplanting and 15 days after transplanting, apply potassium nitrate 3kg and 7kg respectively as topdressing for the first time, and apply potassium sulfate 10kg as topdressing for the second time 40 days after transplanting. Fertilizer preparation method: with embodiment one.

Abstract

The invention discloses special compound fertilizer for Zimbabwe flue-cured tobacco KRK26 and a fertilization method thereof. The weight ratio of nitrogen, phosphorus and potassium in the compound fertilizer is (7.5-8.5): (9.5-10.5): (31-33). The compound fertilizer disclosed by the invention has the advantages that the proportion of high-quality Zimbabwe flue-cured tobacco KRK26 can be increased, the length and width of lumbar leaves are improved, and the blackleg resistance is improved.

Description

technical field [0001] The invention belongs to the field of agricultural technology, in particular, the invention relates to a special compound fertilizer for Zimbabwe flue-cured tobacco KRK26 and a fertilization method thereof. Background technique [0002] Flue-cured tobacco KRK26 was issued by the Zimbabwe Tobacco Research Institute (Kutasaga) in 2001. A male sterile hybrid bred by crossing MS k326 and RW (race 1 resistant to angular leaf spot and root-knot nematode). Variety Characteristics: KRK26 is a mid-to-late maturing variety with well-balanced ripening speed and medium to high yield potential. The quality of the leaves produced is good, the mature particles are good, and the lemon-colored tobacco leaves are more than KM10 (released by Kutasaga in 1984) and KE1 (released by Kutasaga in 1968). The variety has a well-developed root system and good drought resistance. KRK26 has good overall performance from the seedling stage to the field stage, with strong growth, ...
