Problems solved by technology

[0007] The disadvantage of this composition is that it requires a large amount (80g-3kg per 1 ha) of expensive (50,000-75,000 US dollars per 1kg) 5-aminolevulinic acid, which increases the price of the composition itself and is economically unsuitable
This composition has another disadvantage
5-Aminolevulinic acid is a herbicide which, under certain conditions, may, under certain conditions, risk retarding the growth of cultivated plants to which it is applied

example 1

[0108] For lettuce grown indoors, the effect of the composition to increase the activity of nitrate reductase contained in lettuce leaves was shown.

[0109] The components (wt%) of the composition (part 1) are: chitosan-20 with a molecular weight of 50kDa, nitrate reductase active substance-27, chlorophyll synthesis-promoting substance-31, organic acid-20, and surfactant-2.

[0110] The components (wt%) of the composition (part 2) are: chitosan-15 with a molecular weight of 170kDa, nitrate reductase active substance-25, chlorophyll synthesis promoting substance-34, organic acid-25, and surfactant-1.

[0111] Table 1 shows the data related to use case 1. As shown by the data, nitrate reductase activity was consistently higher than the control over a 7 day period after the lettuce was sprayed with the composition.

Abstract

A composition for reducing the content of nitrate in a cultivation plant, characterized in that the composition comprises chitosan, an organic acid, a nitrate reductase activator, and a chlorophyll synthesis promoter, in the following mass ratio (%): chitosan 15 to 25 organic acid 15 to 25 nitrate reductase activator 25 to 30 chlorophyll synthesis promoter 29 to 35.

Description

technical field [0001] The present invention relates to a technique for reducing the nitrate content in vegetables, fodder and other crops by using biologically active substances that do not substantially damage the environment in the field of agriculture, especially in the field of cultivated plant production, thereby Improve the quality of crop products. Background technique [0002] As we all know, nitrates contained in food may cause damage to human health, reduce the hemoglobin content in the blood, etc., and cause many metabolic disorders. Nitrogen in this nitrate state is considered to be a causative substance that promotes the formation of mutagenic and carcinogenic nitrosoamines in vivo. [0003] For this reason, people have been looking for ways to reduce the nitrate content of cultivated plant products, especially vegetables that are eaten without heating, and cultivated plants for livestock feed that may be mixed with nitrate in milk and other livestock products...
