Fertilization method capable of improving nutritional quality of carrots

Abstract

The invention belongs to the technical field of carrot planting, and particularly relates to a fertilization method capable of improving the nutritional quality of carrots. The method comprises the following specific steps: spraying a nutrient solution to leaf surfaces once separately at the late stage of lotus throne formation and the middle stage of succulent root expansion, wherein the sprayingamount at the late stage of lotus throne formation is 14-15 L / mu, and the spraying amount at the middle stage of succulent root expansion is 19-20 L / mu; and applying a tomato fermentation liquid to roots at the early stage of succulent root expansion, wherein the application amount of the roots is 280-290 L / mu, and the nutrient solution is prepared from the following raw materials: erythritol, copper chloride, iron sulfate, eleocharis polysaccharide, black rice polysaccharide, pueraria flower polysaccharide, mangosteen polysaccharide and water. Through the method, promotion of thickening of leaves, increase of the photosynthesis efficiency, inhibition of occurrence of succulent root diseases and effective promotion of thick growth of succulent roots are achieved, so that the surfaces of the carrots are smooth and straight, the commercial value is increased effectively, the content of carotene, vitamin C and total sugar in the carrots is increased effectively, and the nutritional quality of the carrots is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of carrot planting, in particular to a fertilization method for improving the nutritional quality of carrots. Background technique [0002] Carrots contain plant cellulose, which can promote intestinal peristalsis, remove toxins accumulated in the intestinal tract, and improve constipation; carrots also contain carotene, anthocyanins, vitamin C and other substances, which have strong antioxidant effects and can reduce free Radical damage, remove eye free radicals, protect eyes, improve vision, improve body function, enhance cell activity, improve immunity, protect liver and liver, can remove vascular garbage, soften blood vessels, and have the effect of lowering blood pressure and blood sugar; Carrots are rich in vitamins, especially vitamin A, which is an essential substance for bone growth and can also promote cell growth, so it can supplement the vitamins that the human body lacks; carrots also have the e...

Problems solved by technology

[0003] Tomato is an annual or perennial herbaceous plant belonging to the family Solanaceae. The fruit is rich in nutrients, but the tomato is not easy to store, and it is easy to rot and deteriorate. At present, there is no good related utilization of rotten tomato, which largely leads to resource shortage. Waste, so applying moldy and rotten tomatoes to carrot planting can effectively improve resource utilization and reduce carrot planting costs
