Abstract

The invention belongs to the technical field of plant nutrient liquid and particularly discloses nutrient solution capable of improving low-temperature resistance of tomatoes as well as a preparationmethod and application thereof. The nutrient liquid comprises urea, potassium nitrate, nitric acid tetrahydrate, monopotassium phosphate, magnesium sulfate heptahydrate, ammonium molybdate tetrahydrate, chelated iron, boric acid, manganese sulfate monohydrate, zinc sulfate heptahydrate, copper sulfate pentahydrate, 5-aminolevulinic acid and the like. The nutrient liquid is applied to blooming andfruiting periods of the tomatoes and can completely meet the nutrients needed in the growing process of the tomatoes; and the formula and the use amount of the nutrient liquid are adjusted according to different nutrient demanded quantity and demanded varieties in different growing periods of the tomatoes, so that the low-temperature resistance of the tomatoes can be improved significantly, the content of effective nutritional substances of the tomatoes is increased and the quality of the tomatoes is improved.

Description

technical field [0001] The invention belongs to the technical field of plant nutrient solution, and in particular relates to a nutrient solution capable of improving low-temperature resistance of tomatoes, a preparation method and application thereof. Background technique [0002] Tomato belongs to Solanaceae tomato genus, is a warm-loving vegetable crop, tomato fruit is rich in nutrition, rich in vitamins and carotene, has excellent health care effect, and is favored by consumers. In recent years, due to consumer and market demand, it has been widely used in off-season facility cultivation. In facility cultivation, because the soil is often in a state of no rainwater leaching, high temperature, high humidity, and high evaporation, and the crops in the facility are often cropped continuously, the facility soil produces secondary salinization, nutrient imbalance, compaction and acidification, and microbial flora. Imbalance and continuous cropping obstacles and many other pro...
