Problems solved by technology

At present, the preparation method of nutrient solution on the market is to mix various inorganic quick-acting water-soluble nutrients, add water to dissolve and dilute, and the plant nutrient solution obtained in this way has obvious defects in nutritional balance and absorption utilization rate.
At the same time, there is no better nutrient solution to improve the ability of plants to resist low temperature and freezing damage.

Abstract

The invention discloses a plant frost damage-preventing nutritional solution and a preparation method thereof. The plant frost damage-preventing nutritional solution is prepared from the following components in parts by weight: 105 to 140 parts of sodium hydroxide water solution, 340 to 380 parts of plant seed meal, 256 to 294 parts of peat, 45 to 72 parts of potassium hydroxide, 163 to 184 parts of hydrobromic acid, 17 to 52 parts of trace element additive, 190 to 217 parts of alcohol, 75 to 95 parts of rosin, 63 to 84 parts of gibberellin and 45 to 80 parts of brassinolide. The plant frost damage-preventing nutritional solution has the advantages that after the nutritional solution is sprayed and applied to a plant in the end of autumn, winter and early spring, the plant can normally grow, the crop output is increased, the production cost is reduced, and the labor intensity of workers is decreased; the photosynthesis time of the plant is prolonged, organic agriculture products and pollution-free products can be produced, and the application prospect is wide in the fields of agriculture, forestry and the like.

Description

technical field [0001] The invention relates to the technical field of nutrient solutions, in particular to a nutrient solution for preventing freezing damage of plants and a preparation method thereof. Background technique [0002] Nutrient solution is a functional liquid with less impurities and multiple nutrients. It plays an important role in plant nutrition supplement and soilless cultivation. Because of its high nutrient content and low dosage, it is widely used in daily life and agricultural production. There are tons of uses. At present, the preparation method of nutrient solution on the market is to mix various inorganic quick-acting water-soluble nutrients, add water to dissolve and dilute, and the plant nutrient solution obtained in this way has obvious defects in nutritional balance and absorption utilization rate. Simultaneously, there is no better nutrient solution to improve the low temperature resistance and freezing damage ability of plants. Contents of t...
