Embodiment 1

[0027] A fresh-keeping method for agricultural products, comprising the following steps:

[0028] Step 1: During the cultivation process of agrochemical products, calcium salts are sprayed from the mature stage. The calcium salts are nitrates. The spraying method is to spray nitrates once every week. The nitrate concentration is 0.5%. 1 liter / tree;

[0029] Step 2: The agricultural products are covered with transparent paper bags during the ripening period, and the bags are removed 9 days before the harvesting period. The transparent paper is ordinary white thin paper with good light transmission;

[0030] Step 3: picking agricultural products and cleaning them;

[0031] Step 4: Under anaerobic conditions, carry out ultraviolet sterilization on agricultural products;

[0032] Step 5: Cleaning the agricultural products again, spraying fresh-keeping liquid on the surface of the agricultural products, the amount of the fresh-keeping liquid accounts for 1% of the weight of the a...

Embodiment 2

[0044] A fresh-keeping method for agricultural products, comprising the following steps:

[0045] Step 1: During the cultivation process of agrochemical products, calcium salts are sprayed from the mature stage. The calcium salts are nitrates. The spraying method is to spray nitrates once every 2 weeks. The nitrate concentration is 1.5%. 2.5 liters / tree;

[0046] Step 2: The agricultural products are covered with transparent paper bags during the ripening period, and the bags are removed 12 days before the harvesting period. The transparent paper is sulfuric acid paper with good light transmission;

[0047] Step 3: picking agricultural products and cleaning them;

[0048] Step 4: Under anaerobic conditions, carry out ultraviolet sterilization on agricultural products;

[0049] Step 5: Cleaning the agricultural products again, spraying fresh-keeping liquid on the surface of the agricultural products, the consumption of the fresh-keeping liquid accounts for 5% of the weight of...

Embodiment 3

[0060] Embodiment 3: a kind of fresh-keeping method of agricultural product, comprises the following steps:

[0061] Step 1: The agrochemical products are sprayed with calcium salt from the mature stage during the cultivation process. The calcium salt is nitrate. The spraying method is to spray nitrate once every 2 weeks. The nitrate concentration is 1.0%. 2.0 liters / tree;

[0062] Step 2: The agricultural products are covered with transparent paper bags during the ripening period, and the bags are removed 11 days before the harvesting period. The transparent paper is ordinary white thin paper with good light transmission;

[0063] Step 3: picking agricultural products and cleaning them;

[0064] Step 4: Under anaerobic conditions, carry out ultraviolet sterilization on agricultural products;

[0065] Step 5: Cleaning the agricultural products again, spraying fresh-keeping liquid on the surface of the agricultural products, the consumption of the fresh-keeping liquid account...

Abstract

The invention discloses an agricultural product freshness preservation method and relates to the technical field of agricultural product freshness preservation. In the cultivation process, from the maturation period, calcium salt is sprayed to agricultural products, the calcium salt is nitrate, a spraying method is that the nitrate is sprayed once every 1-2 weeks, the concentration of the nitrate is 0.5%-1.5%, and 1-2.5 L of the nitrate is sprayed to each plant; in the maturation period, the agricultural products are bagged with transparent paper bags, or a light reflection film is paved; the bags are removed 9-12 days before the harvesting period, and the transparent paper is common white thin paper with good light transmission performance or vegetable parchment. By means of the technical scheme, the production efficiency is high, and the freshness preservation steps are reasonable; by means of the method for agricultural product freshness preservation, the phenomenon that the agricultural products have black hearts or rot can be effectively avoided, the water losing speed of the agricultural products can be remarkably reduced, and the freshness preservation effect is ideal.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of agricultural products, in particular to a fresh-keeping method of agricultural products. Background technique [0002] The storage and preservation technology of fresh and live agricultural products is to provide the storage environment and conditions artificially to achieve the lowest metabolic level of the products without causing physiological disorders, so as to achieve the purpose of prolonging the life of the products. The industry has introduced fresh agricultural product preservation technology using the stable temperature range (ice temperature) above the freezing point of products below 0°C. This technology has the potential to extend the storage period and reduce storage diseases for products that are not sensitive to chilling damage and have a lower freezing point temperature. effect. However, for large-scale commercial cold storage, it is impossible to achieve temperature co...
