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

Embodiment 1

[0043] 1. take by weighing the sodium carboxymethyl cellulose of 10 weight parts, be dissolved in the water of 15 weight parts, obtain the sodium carboxymethyl cellulose aqueous solution;

[0044] 2. Add 5 parts by weight of amino acid chelated calcium to the sodium carboxymethylcellulose aqueous solution described in step 1., and heat to 40-50° C.;

[0045] ③Then add 3 parts by weight of ethylene glycol to the solution in step ②, stir at 40-50°C for 30-40min, and then place it at room temperature.

[0046] The control effect of this embodiment on fruit cracking was tested on jujube trees. See comparative test 3.

[0047] The function of each ingredient is explained as follows:

[0048] Amino acid chelated calcium: Amino acid chelated calcium is a new type of organic calcium supplement, which can be directly absorbed by plants after spraying. Calcium is an important structural component in the cell wall. It combines with pectin to form calcium pectate, which increases the T...

Embodiment 4

[0061] 1. take by weighing the sodium carboxymethyl cellulose of 10 weight parts, be dissolved in the water of 15 weight parts, obtain the sodium carboxymethyl cellulose aqueous solution;

[0062] 2. Add 5 parts by weight of amino acid chelated calcium to the sodium carboxymethylcellulose aqueous solution described in step 1., and heat to 40-50° C.;

[0063] ③Then add 3 parts by weight of ethylene glycol to the solution in step ②, stir at 40-50°C for 30-40min, and then place it at room temperature;

[0064] ④ Add 0.5 parts by weight of brassinolide to the solution in step ③ and stir evenly to obtain the anti-cracking nutrient for fruit.

[0065] During the test, it was found that the agent made of sodium carboxymethylcellulose, ethylene glycol and amino acid chelated calcium was applied in large-scale production. Although the anti-cracking effect was very good, it was affected by the protective film formed after spraying. , the rate of absorption of calcium ions by the fruit ...

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...
