A planting method for reducing spinach nitrate content

Abstract

The invention belongs to the technical field of planting of spinach, in particular to a planting method capable of reducing content of nitrate in spinach. The planting method specifically comprises the following steps of (1) treating of spinach seeds before seeding; (2) field management after seeding. The planting method has the advantages that before seeding, the spinach seeds are sequentially impregnated by a boric acid water solution and a citric acid-chelating copper water solution, so that the activity of reductase in nitric acid is effectively improved, the nitrogen assimilation is enhanced, the accumulation of nitrate in the growth process of spinach is inhibited, the absorbing ability on nutrients is effectively enhanced, and the green and health growth of the spinach is promoted;after seeding, a fertilizer solution is applied to the root for two times, and a magnesium sulfate water solution is sprayed, so that the growth of the spinach is promoted, the synthesis of protein and vitamin C is promoted, the certain thinning function on the nitrate in a human body is realized, the nitrate nitrogen is promoted to transfer from liquid bubble into cytoplasm and reduce, the activity of nitrifying bacteria is inhibited, the content of amino acid is increased, the protein is synthesized, the content of nitrate in the spinach is reduced, and the safety and nutrient quality in useare improved.

Description

Background technique [0002] Spinach is sweet in taste, cool in nature, sweet and mellow, tender and delicious, enters the large intestine and stomach meridian, can nourish blood and stop bleeding, benefit the five internal organs, unblock the stomach, regulate Qi, activate blood vessels, quench thirst and moisten intestines, restrain yin and moisten dryness, nourish yin and calm the liver , help digestion; mainly treat high blood pressure, headache, dizziness, hot red eyes, diabetes, constipation, indigestion, bruises, epistaxis, blood in the stool, scurvy, stagnant stool, spinach is rich in carotene, vitamin C, calcium, phosphorus, and a certain amount of beneficial ingredients such as iron, chromium, potassium, and vitamin E can provide the human body with various nutrients and enhance physical fitness. ...

AI Technical Summary

Problems solved by technology

[0003] Nitrate nitrogen is one of the main sources of nitrogen absorbed by plants. It exists widely in the environment in the form of nitrate. Spinach is a plant that easily accumulates nitrate. Nitrate has no direct toxic effect on the human body, but after entering the human body, It will be reduced to nitrite under the action of microorganisms. Nitrite is a toxic substance that can quickly enter the blood of the human body and oxidize the low iron in hemoglobin to high iron, making it form methemoglobin that cannot transport oxygen, thus affecting oxygen. Nitrite can also react with various amines in other foods ingested by the human body to form strong carcinogens - nitrosamines, which have been found in more than 120 kinds of nitrosamines. Among the amine compounds, 75% of nitrosamines are confirmed to be carcinogenic; therefore, inventing a planting method that can effectively inhibit the accumulation of nitrate in spinach can effectively improve its food safety and nutritional quality
