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

Plantation of granulated sugar tangerine and freezer band leaf preservation method

Technical field:

The present invention relates to fruit plantation and preservation technique, particularly a kind of granulated sugar tangerine plantation and freezer band leaf preservation method.

Technical background:

Granulated sugar tangerine or rock sugar tangerine are the top grade of Citrus, be the peculiar and main fruit of planting of China South China, it is high that fruit contains sugar part, nutritious, unique flavor, at home and abroad be loved by the people as a kind of rare fruit on the fruit market, so price is also higher, but the granulated sugar tangerine maturing stage is concentrated, and pericarp is thin, sugar part is high, very easily rot after the harvesting, only can preserve 3-6 days under the normal temperature, Time To Market is short, is difficult to long-distance transport and market regulation, the value of commodity also is easy to forfeiture, so huge business opportunity is contained in the preservation and freshness of granulated sugar tangerine.

The preservation technique of present fruit has multiple, and the one, drug immersion is fresh-keeping, promptly soaks to suppress the disease of microorganism with the fresh-keeping liquid that contains preservative; The 2nd, use the sulphur dioxide sootiness, be the disease that suppresses microorganism equally; The 3rd, preservation by low temperature makes fruit be under the hibernation-like state and delays to rot, and also can also use or dual-purpose by multiple preservation technique, but all is just to do fresh-keeping processing behind the fruit picking.Facts have proved, above-mentioned preservation technique is effective to most fruit, but the granulated sugar tangerine is produced little effect, reason is that granulated sugar tangerine pericarp is thin, sugar is part high, moisture content is many, fruit is soft, metabolism is vigorous, very easily rotten, its fresh-keeping difficulty is only second to lichee, so freshness date is short, is difficult to form business opportunity, so must find a new way.

Summary of the invention:

The objective of the invention is to overcome the short drawback of above-mentioned granulated sugar tangerine freshness date, promptly implement the plantation of granulated sugar tangerine and the freezer band leaf preservation method of fresh-keeping measure since the florescence, make every effort to prolong storage period to greatest extent and provide a kind of.

Of the present invention kind of method for planting is: promptly spray promoter flowering stage the granulated sugar tangerine; The fruitlet phase is sprayed inhibitor; Middle fruit phase emphasis replenishes calcium, potash fertilizer; The maturing stage application of organic fertilizers, every fruit stays leaf 2-3 sheet during harvesting, and clip need be put down, and soaks with antistaling agent after the sorting, is added with the basic element of cell division and calcium chloride in the antistaling agent soak, and vanning sign indicating number frame is gone into the freezer precooling then.The preservation method of freezer is: the built-in potassium permanganate of freezer is made reductant, sodium hydroxide is made adsorbent, adopts the controlled atmosphere mode, and thermostatic control is 90-95% at 4-5 ℃, humidity.

Traditional preservation method is just to come into effect medicine and freezer is fresh-keeping after the granulated sugar tangerine is plucked, and the present invention promptly implements fresh-keeping measure since the florescence, and be the band leaf carry out antistaling agent and freezer fresh-keeping, compare between the two, effect is completely different: general freezer is fresh-keeping, and the fruit leaf comes off, freshness date 50-80 days, put on the shelf only 3 days time, rotten rapidly after the outbound, decayed fruit rate height.Band leaf of the present invention is fresh-keeping, and freshness date reaches 120-150 days, puts on the shelf for up to 15 days, and the decayed fruit rate is low, only is 5%, and the hardness of fruit, color and luster, local flavor are constant.Because long fresh-keeping period, be beneficial to long-distance traffic and stagger the peak busy season, and the fruit leaf is dark green is as good as with just plucking, can improve feeling of freshness, and increase economic efficiency.Promote the use of on plantation peasant household, the farm in the suitable granulated sugar tangerine place of production of the present invention, is extensive granulated sugar tangerine north fortune and for export taking a firm foundation.

Embodiment:

Of the present invention kind of method for planting is: promptly implement fresh-keeping measure flowering stage the granulated sugar tangerine, can spray commercially available promoter hormone, promote the bud growth.The fruitlet phase is then sprayed commercially available inhibitor hormone, suppresses the summer shoot growth, and its effect is to protect output.Middle really phase foliage spray calcareous fertilisers, the root potassium application promotes the pericarp growth, makes fruit strong, reduces the mechanical damage because of plucking, casing, cause when transporting.Maturing stage application of organic fertilizers, prescribing adequate nutrition can promote that branches and leaves are luxuriant, increase sugar and upgrade, and guarantee fruit original lovely luster after harvesting, can make the picking period postpone the corresponding freshness date that prolonged 10-20 days.Blue or green bright abundant with fruit in season leaf nutrient foot, pluck fresh-keeping laying foundation for staying leaf.Every fruit must stay leaf 2-3 sheet during harvesting, and clip need be put down, and to reduce mechanical damage, also can reduce mechanical damage with the topped of fruit in season leaf.Use iprodione, the bright amine, 2 of amidine after the fruit sorting, conventional antistaling agent such as 4-D soaks, but the antistaling agent soak need add the basic element of cell division and calcium chloride, its effect is sterilization and anticorrosion, delay senility, reduce the generation of pernicious gases such as ethene, the corresponding freshness date that prolonged, soak time 0.5-2 minute, pull out and dry a back vanning sign indicating number frame and go into the rapid precooling of freezer.The preservation method of freezer is:, the built-in potassium permanganate of freezer is made reductant, sodium hydroxide is made adsorbent, prevent pernicious gas, mould vicious circles such as ethene, adopt controlled atmosphere mode combustion gas simultaneously, thermostatic control is 90-95% at 4-5 ℃, humidity, the decayed fruit rate only is 3-5% in 20 days, needs this moment the letter sorting decayed fruit to prevent that mould from stretching, and the decayed fruit rate is lower than 1% after 20 days.After said method is handled, granulated sugar tangerine freshness date was 120 days-150 days, going out the selling time of putting on the shelf behind the stock was 15 days, the hardness of fruit in the freshness date, color and luster, local flavor are constant, the fruit leaf does not come off, still keep dark green feeling of freshness, be as good as during with firm harvesting, to support leaf, Ye Yangguo, chlorophyll closely related to air cleaning with fruit for this.In the experiment, all outsourcing band leaf granulated sugar tangerines are put in storage fresh-keeping simultaneously, and fruit leaf is all withered comes off for it, and decayed fruit rate height, freshness date are short, and this and granulated sugar tangerine kind method for planting are closely related.
