Sugar orange planting method and method for preventing the freshness of the sugar orange with leaves in refrigerators

Abstract

The present invention relates to the technology of fruit plant and freshness prevention, in particular to a sugar orange planting method and a method for preventing the freshness of the sugar orange with leaves in refrigerators. The sugar orange planting method is that: accelerant is splashed at once in sugar orange anthesis; inhibitors are splashed in a small fruit period; calcium and potash fertilizers are importantly supplemented in a middle fruit period; organic fertilizers are used in a maturation period. When sugar oranges are picked, two to three leaves of every sugar fruit are reserved. After the sugar oranges are graded, freshness prevention agents are used for marinating, and cytokinin and calcium chloride are added in the solution of the freshness prevention agents. The method for preventing the freshness of the sugar orange with leaves in refrigerators is that: potassium permanganate is put into the refrigerators as reducing agents; sodium hydroxide is put into the refrigerators as sorbents; and constant temperature is controlled at 4 DEG C to 5 DEG C, and humidity is 90 to 95% by applying an air-adjusting type. The freshness prevention period of the present invention is long for 120 to 150 days, and the shelf time is long for 15 days. Fruit leaves are green, and are not easy to fall off. The rotten fruit rate is low, and is only 3 to 5%. However, the hardness, color and local flavor of the sugar oranges are not changed, and the sugar oranges are favorable to transport in a long way and stagger peak sale busy seasons. The present invention is suitable for planting peasants and farms in sugar orange production places, and takes a firm foundation for the north transportation and export of the sugar oranges in a large scale.

Description

Technical field: [0001] The invention relates to fruit planting and fresh-keeping techniques, in particular to a method for planting tangerines and keeping fresh with leaves in a cold storage. technical background: [0002] Sand Tangerine or Rock Tangerine is the top grade of citrus. It is a unique and main planted fruit in South China. The fruit has high sugar content, rich nutrition and unique flavor. It is popular as a rare fruit in domestic and foreign fruit markets. People love it, so the price is high. However, the sugar tangerine has a concentrated ripening period, thin peel and high sugar content. It is easy to rot and deteriorate after picking. It can only be stored for 3-6 days at room temperature. It has a short time to market and is difficult to transport and market. Adjustment, the value of the commodity is also easy to lose, so the storage and preservation of shatangju has huge business opportunities. [0003] At present, there are many fresh-keeping technolog...

Problems solved by technology

Practice has proved that the above-mentioned fresh-keeping technology is effective for most fruits, but it has little effect on Shatangju. The difficulty of keeping fresh is second only to lychee, so the fresh keeping period is short and it is difficult to form business opportunities, so another way must be found
