Nutrition regulator special for leaf spraying and preparation method thereof

The invention relates to a special nutrition regulator for spraying leaves and a preparation method thereof. The special nutrition regulator is prepared from the following raw materials in parts by weight: 10-20 parts of monopotassium phosphate, 5-15 parts of compound amino acid raw powder, 1-3 parts of sucrose fatty acid ester, 15-20 parts of rhamnolipid, 8-12 parts of chelated titanium potassium, 2-4 parts of emulsified pressed sesame oil, 50-70 parts of decomposed sesame cake extract and 480-680 parts of clean water. The sprayed tobacco leaf petroleum ether extract is used for synthesizing needed amino acid, lipid, acid and other substances, meanwhile, sprayed phosphorus and potassium nutrients and small molecule active substances promote photosynthesis of leaves and metabolism of secondary substances, synthesis accumulation of dry substances of the leaves and the petroleum ether extract is increased, the yield of the petroleum ether extract is remarkably increased, and the yield of the tobacco leaf is inc
