Description

Compound composition of palmitic acid and berbamine and application Technical Field The invention relates to the technical field of plant stress physiological regulation and agricultural chemistry, in particular to an exogenous application compound composition composed of fatty acid compounds and amine compounds and application thereof in improving drought resistance of crops and promoting crop growth. Background Most of the existing drought-resistant agents are chemical synthetic substances, and have good effects on single crops, so that the problem of environmental compatibility of the drought-resistant agents still needs to be concerned. Meanwhile, different drought-resistant agents are required to be applied to different crops, and management complexity in actual agricultural production is increased. Therefore, there is a need to develop a composition which is relatively environmentally friendly in terms of ingredients, suitable for use in a variety of crops, and capable of improving drought resistance of crops. Disclosure of Invention To address the problems of the prior art, the present disclosure provides a composition for improving drought resistance and/or promoting growth of crops, the composition comprising palmitic acid and berbamine. In some embodiments, the major components of the composition consist of palmitic acid and berbamine. In some embodiments, the mass ratio of palmitic acid to berberine (6-10): 1, preferably 7.6:1. In some embodiments, the concentration of the palmitic acid is 0.20-1.00 mmol/L and the concentration of the berberine is 0.05-0.20 mmol/L. In some embodiments, the concentration of the palmitic acid is 1.00 mmol/L and the concentration of the berberine is 0.10 mmol/L. In some embodiments, the composition may be used as the primary active ingredient of a fertilizer or plant growth regulator. In some embodiments, the composition is applied by foliar spray during the seedling stage. In some embodiments, the crop is flax, corn, soybean or sorghum. The present disclosure also provides a fertilizer for improving drought resistance and/or promoting growth and development of crops, wherein the active ingredients of the fertilizer comprise palmitic acid and berberine. In some embodiments, the mass ratio of palmitic acid to berberine (6-10): 1, preferably 7.6:1. In some embodiments, the concentration of the palmitic acid is 0.20-1.00 mmol/L and the concentration of the berberine is 0.05-0.20 mmol/L. In some embodiments, the concentration of the palmitic acid is 1.00 mmol/L and the concentration of the berberine is 0.10 mmol/L. In some embodiments, the fertilizer is a foliar fertilizer. In some embodiments, the fertilizer further comprises nitrogen, phosphorus, potassium, and/or trace elements required for plant growth. In some embodiments, the nitrogen may be ammonium nitrate, ammonium bicarbonate, etc., the phosphorus may be superphosphate, monoammonium phosphate, etc., the potassium may be potassium chloride, potassium sulfate, potassium nitrate, etc., and the trace element may be zinc sulfate, ferrous sulfate, etc. In some embodiments, the fertilizer further comprises one or more drought-resistant active substances such as proline, betaine, seaweed extract, amino acids, humic or fulvic acids. In some embodiments, the crop is flax, corn, soybean or sorghum. In addition, the application of the composition or the fertilizer in improving drought resistance of crops and/or promoting growth and development of crops is also provided. In some embodiments, the crop is flax, corn, soybean or sorghum. The present disclosure also provides a method for improving drought resistance and/or promoting growth and development of crops, which is characterized in that the composition or fertilizer disclosed in the present disclosure is applied to crops. In some embodiments, the compositions or fertilizers described in the present disclosure are sprayed through the foliage as soon as the object enters the seedling stage. In some embodiments, the composition or fertilizer application method is 1 spray every 3 days, 10 consecutive sprays, a single spray dose of 0.05-0.20L/m 2 leaf area. In some embodiments, the composition or fertilizer is sprayed at least 10 times in succession. In some embodiments, the single spray dose is 0.10L/m 2 leaf area.
