Description

The production method and application of the pretreatment mother liquor of Yangtong cut branches and fresh-keeping

technical field

The invention relates to a production method and application technology of a fresh-keeping mother liquor prepared by cutting off leafy branches of Cleyera japonica Thunb. and performing pretreatment.

Background technique

Due to the needs of flower arrangement, sacrifice and daily life and other activities, Japan consumes a large amount of Yangtong cut branches every year, and the demand is increasing. The annual consumption of cut leaves and branches reaches about 35 billion yen (approximately RMB 5 billion), and my country’s annual exports account for about 65% of Japan’s total annual demand. Therefore, cut branches of Yangtong have a large consumer market in Japan , my country's use of Yangtong production can create greater economic benefits.

For a long time, because the branches of Yangtong are cut from the branches of the same year, generally 1-2 days after harvesting, the leaves begin to wither, yellow and fall off. They are cut and sorted from the mountains in my country, and then transported to Japan after export procedures. Therefore, prolonging the fresh-keeping period of Yangtong cut branches has become the key to earning foreign exchange from the export of Yangtong products. With its natural climate advantages, Zhejiang has become one of the major export provinces of Yangtong, but there are few studies on Yangtong fresh-keeping solution, and in actual production, water is often used for pretreatment. The treatment fluid has certain practical significance.

After searching, there is only a report on the fresh-keeping literature of poplar cut branches in 1998 in the "Research Briefing on Fresh-keeping Technology of Wild Poplar Branches" by the Management Office of Lushan Nature Reserve in Jiangxi. Powder, α-naphthalene acetic acid, and 2, 4-D four plant growth regulators were used as the treatment solution before postharvest storage and transportation. After 24 hours of treatment, indolebutyric acid 200 mg/kg had the best effect, which could prolong the growth of poplar tree. The preservation life is up to 35 days.

Contents of the invention

The technical problem to be solved by the present invention is to provide a production method and application technology of the pretreatment mother liquor for fresh-keeping and fresh-keeping of poplar tree branches.

To solve this technical problem, the following technical solutions are adopted:

The application of the mother liquor prepared by the above-mentioned Yangtong cut branch fresh-keeping pretreatment mother liquor production method is carried out according to the following steps:

(1) Dilution of the mother liquor: Dilute the mother liquor and the dilution water in a ratio of 1:4 to form a fresh-keeping pretreatment liquid for cut branches of Yangtong;

(2) Soaking branches: After the collected branches of Yangtong are gradually obliquely cut, they are bundled into bundles, and the incisions of the cut branches of Yangtong are immersed in the above-mentioned pretreatment solution for 24 hours;

(3) Wrapping with liquid cotton of cut branches of Yangtong: take out Yangtong after soaking for 24 hours, wrap the cuts of cut branches of Yangtong bundle by bundle with absorbent cotton soaked with the fresh-keeping pretreatment liquid of cut branches of Yangtong Afterwards, it was sent to the cold storage for low-temperature storage and transportation, and the pretreatment of poplar branches to keep fresh was completed.

The beneficial effect of the present invention is to provide a kind of practical and effective fresh-keeping pretreatment mother liquor for the poplar cut branches exported to Japan in large quantities, which is 14 days and 10 days longer than the treatment with clear water and 200 mg/kg indole butyric acid fresh-keeping solution respectively It also saves half the cost of indole butyric acid, which opens up a new way to solve the problem of keeping fresh poplar branches with long storage and transportation period; Shipping and packaging costs.

Detailed ways

The present invention will be further described in detail below in conjunction with the examples: first, each raw material and its weight ratio are listed in Table (1) according to 9 examples.

Example 1 (the raw materials and weight distribution ratios of Example 1 in the comparison table (1): first dissolve 0.08 parts of thiadizuron powder with a concentration of 0.1 mol/L NaOH to complete dissolution, and then use a concentration of 0.1 mol/L HCL Adjust the pH to 7 (the weight of NaOH and HCL is negligible due to the low concentration and dosage of NaOH and HCL), and prepare a thidiazuron solution, and then mix it with 80 parts of sucrose, 0.08 parts of ascorbic acid, 0.16 parts of acetylsalicylic acid and 4000 parts of industrial Stir with water to mix well, and serve in barrels. In order to save costs, the sucrose in the above raw materials can be used in food grade, and the others can be used in industrial grades, and analytical grades should be used as little as possible. All the rest of Examples 2-9 can be prepared in the same way as in Example 1 by comparing the raw materials and their weight ratios in the corresponding examples in the table. Wherein preferred with embodiment 4.

Table 1)

The yellowing of leaves often occurs during the transportation of poplar branches. In this method, a new type of high-efficiency plant growth regulator, thiadizuron (N-phenyl-N-1,2,3-thiadiazole-5-urea , English name thidiazuron, abbreviated as TDZ), it has extremely strong biological activity, and its ability to induce plant cell division is more than 1000 times higher than that of general cytokinins. Initially, high-concentration thiadiuron was used as a defoliant in cotton harvesting, and the price was low. In recent years, it has been found that low-concentration has a fresh-keeping effect on ornamental plants, so it should have a certain effect on inhibiting the yellowing of poplar leaves. At present, cutting branches of Yangtong only uses the incision soaked in water combined with low-temperature storage and transportation technology, which cannot solve the problem of leaf yellowing, and the fresh-keeping effect is not ideal.

Among the raw materials, sucrose provides nutrition for the cut branches and leaf cells, regulates cell osmotic pressure, and promotes water absorption; ascorbic acid can reduce the pH value of the fresh-keeping solution, inhibit microbial proliferation, and reduce catheter blockage. Decrease in protein content and maintain the integrity of cell membrane. Acetylsalicylic acid is a fungicide, which has the effect of preventing the reproduction of harmful microorganisms and inhibiting the production of ethylene. Thidiazuron is a new type of high-efficiency plant growth regulator, it can inhibit the degradation of chlorophyll, regulate the growth and development of plants through the action of other plant hormones and physiologically active substances, due to the obvious effect of inhibiting leaf yellowing, Compared with water treatment and 200 mg/kg indole butyric acid preservative solution, the yellowing of Yangtong leaves was delayed for 14 days and 10 days, respectively.
