The invention discloses a composition for improving photosynthetic efficiency. The composition mainly comprises at least one choline salt and sodium bisulfate according to a weight ratio of (50: 1) to (1: 10). The at least one choline salt is selected from choline chloride, choline phosphate, choline sulfate, choline citrate, choline salicylate and choline succinate. Preferably, the choline salt is choline chloride. A weight ratio of the choline salt to sodium bisulfate in the composition is in a range of (20: 1) to (1: 10) and preferably is in a range of (5: 1) to (2: 1). When being directly used for plants, the composition can be diluted until a choline salt concentration is in a range of 40 to 1000mg/L and a sodium bisulfate concentration is in a range of 10 to 800mg/L, and preferably, the composition can be diluted until a choline salt concentration is in a range of 300 to 1000mg/L and a sodium bisulfate concentration is in a range of 50 to 120mg/L.
Description
technical field [0001] The invention relates to an agricultural composition capable of improving photosynthetic efficiency. Background technique [0002] Photosynthesis and photorespiration in plants occur simultaneously. Photosynthesis is the process by which plants use light energy to convert carbon dioxide, water or hydrogen sulfide into carbohydrates and store energy. In contrast, photorespiration is the process of losing energy, consuming oxygen and producing carbon dioxide. If photorespiration occurs in photosynthetic organisms, photorespiration cancels out about 30% of photosynthesis. Therefore, reducing photorespiration is considered to be one of the ways to improve photosynthetic efficiency and yield of crops. Sodium bisulfite is a photorespiration inhibitor, which can effectively inhibit photorespiration. Since the 1980s, there have been many reports in my country on the inhibitory effect of sodium bisulfite on crop photorespiration, the improvement of photosyn...
