Fruit anti-cracking nutritional agent and preparation method thereof

Abstract

The invention discloses a fruit anti-cracking nutritional agent and a preparation method thereof. The fruit anti-cracking nutritional agent comprises the following raw materials in part by weight: 5 to 15 parts of sodium carboxymethylcellulose, 3 to 7 parts of calcium, 1 to 5 parts of ethylene glycol, 0.01 to 0.9 part of plant growth regulator and 10 to 20 parts of water. The preparation method comprises the following steps of: (1) dissolving the sodium carboxymethylcellulose with the water so as to obtain sodium carboxymethylcellulose aqueous solution; (2) adding the calcium into the sodium carboxymethylcellulose aqueous solution and heating to the temperature of between 40 and 50 DEG C; and (3) adding the ethylene glycol into the solution obtained in the step (2), stirring at the temperature of between 40 and 50 DEG C for 30 to 40 minutes, lowering the temperature to the normal temperature, adding the plant growth regulator and stirring uniformly so as to obtain the fruit anti-cracking nutritional agent. The medicinal agent forms a film after being applied by spraying, is difficultly dissolved in the water for the second time after being dried, has a controllable thickness and can effectively lower fruit cracking rate by about 10 percent.

Description

technical field [0001] The invention relates to an anti-cracking nutrient for fruit, in particular to an anti-cracking nutrient for fruit and a preparation method thereof. Background technique [0002] Fruit cracking is a physiological disease. The starting point of fruit cracking is generally the sunny side of the fruit surface and the part that is first colored. This is related to the fact that after the fruit skin is exposed to direct sunlight, there are small sunburn marks, which reduce the toughness of the skin. Regarding the mechanism of jujube fruit cracking, domestic scholars believe through a large number of studies that: the precipitation of the fruit entering the white ripening period and the lack of calcium in mineral nutrition will have an impact on this physiological disorder. Under the same management conditions, the fruits of jujube trees with high calcium content generally have a lower fruit cracking rate, which is due to the combination of calcium and pecti...

AI Technical Summary

Problems solved by technology

Among them, variety improvement and rain-shelter cultivation are very effective, but it is impossible to implement them on all jujube trees. This is because the cost of rain-shelter cultivation is high, and variety improvement is difficult to promote in a large area due to the age of the tree and the planting mode of each family; Calcium spraying and organic fertilizer application are effective, but not ideal

For large fruit (such as apples), the fruit can be protected by bagging early to avoid the stimulation of rain and strong light on the epidermal cells. This management measure is very effective in preventing fruit cracking, but due to the growth characteristics of jujube trees, It is difficult to implement bagging on jujube fruit
