Embodiment 1

[0026] After uniformly mixing 15 parts of EDTA and 25 parts of jasmonic acid calculated in parts by weight in the C component, they were dissolved in water to obtain the C component mixed solution, and the C component mixed solution was sprayed on the leaf surface of the tobacco plant in the mid-term growth period, every Each time consumption is 50kg per mu; Spray the mixed solution of B component after interval 3 days, each consumption is 50kg per mu, and described B component mixed solution is 2 parts of cobalt chloride, calcium chloride 100 parts by weight. 1 part and 3 parts of mannitol are uniformly mixed and dissolved in water to obtain a mixed solution; the mixed solution of the A component is sprayed for the first time after an interval of 3 days, and the mixed solution of the A component is sprayed for the second time after an interval of 10 days. Solution, each dosage is 70kg per mu, and the mixed solution of the A component is the mixed solution obtained by dissolvin...

Embodiment 2

[0028] 10 parts by weight of EDTA and 30 parts of jasmonic acid in component C are uniformly mixed and dissolved in water to obtain a mixed solution of component C, and the mixed solution of component C is sprayed on the leaves of tobacco plants in the middle and late stages of vigorous growth. The dosage is 40kg per mu; after 2 days, the mixed solution of component B is sprayed, and the dosage is 60kg per mu. The mixed solution of component B is 3 parts of cobalt chloride and 50 parts of calcium chloride in parts by weight. and 5 parts of mannitol are uniformly mixed and dissolved in water to obtain a mixed solution; the mixed solution of the A component is sprayed for the first time after an interval of 5 days, and the mixed solution of the A component is sprayed for the second time after an interval of 8 days. Solution, each dosage is 100kg per mu, and the mixed solution of the A component is the mixed solution obtained by dissolving in water after uniformly mixing 1 part of...

Embodiment 3

[0030] After uniformly mixing 20 parts of EDTA and 20 parts of jasmonic acid calculated in parts by weight in the C component, they were dissolved in water to obtain the C component mixed solution, and the C component mixed solution was sprayed on the leaf surface of the tobacco plant in the mid-term growth period, every The dosage is 80kg per mu; after 5 days, the mixed solution of component B is sprayed, and the dosage is 30kg per mu. The mixed solution of component B is 0.5 parts of cobalt chloride and 150 parts of calcium chloride in parts by weight. 1 part and 2 parts of mannitol are uniformly mixed and dissolved in water to obtain a mixed solution; the mixed solution of the A component is sprayed for the first time after an interval of 2 days, and the mixed solution of the A component is sprayed for the second time after an interval of 15 days. Solution, each dosage is 30kg per mu, and the mixed solution of the A component is a mixed solution obtained by dissolving in wat...

Abstract

The invention belongs to the field of tobacco cultivation, and particularly relates to a regulating agent which at least comprises a component A, a component B and a component C. The component A comprises, by weight, 1-10 parts of polyamine, 1-10 parts of sodium nitroprusside and 2-5 parts of sodium sulfite. The component B comprises, by weight, 0.5-3 parts of cobalt chloride, 50-150 parts of calcium chloride and 2-5 parts of mannitol. The component C comprises, by weight, 10-20 parts of EDTA (ethylene diamine tetraacetic acid) and 20-30 parts of jasmonic acid. The component A, the component B and the component C are separately used. Experimental researches show that the regulating agent is sprayed to tobaccos, early aging, albinism, burn and brown spots of the tobaccos in the field are obviously relieved, physiology and quality indexes are remarkably improved, use effects are remarkable, forced mature caused by high temperature of flue-cured tobacco can be effectively prevented, and tobacco quality is improved.

Description

technical field [0001] The invention relates to the field of tobacco cultivation, in particular to the application of a regulating agent. Background technique [0002] Tobacco is a plant that is very sensitive to changes in environmental conditions. Ecological factors have a greater impact on the yield and quality of tobacco leaves. Among them, climate factors are the main ecological factors that create high-quality and characteristic tobacco leaves. Studies have shown that compared with foreign high-quality tobacco leaf production areas, the meteorological conditions of flue-cured tobacco in my country during the field growth period are mainly manifested in: relatively insufficient sunshine; relatively low temperature in the early stage, and relatively high temperature in the later stage. This phenomenon is particularly prominent in the central and southern smoking areas of my country. [0003] The Nanling Mountains are an important climate boundary between Central China a...
