Embodiment 1

[0027] Prepare an aqueous solution of methyl jasmonate with distilled water, and the concentration of methyl jasmonate is 0.001 μmol.L -1 .

[0028] Dried cabbage seeds suitable for sowing production were soaked in the same methyl jasmonate seed soaking solution as the total volume of seeds at room temperature for 1 day, and then sowed immediately.

[0029] Others are operated according to the conventional cabbage planting method.

[0030] The quality of the Chinese cabbage heart is significantly improved compared with that produced by the common method, the soluble solids and vitamin C content of the Chinese cabbage heart are improved, and the freshness of the Chinese cabbage heart is improved.

Embodiment 2

[0032] Prepare an aqueous solution of methyl jasmonate with ordinary well water, and the concentration of methyl jasmonate is 100 μmol.L -1 .

[0033] Soak the dried cabbage seeds suitable for sowing production at room temperature in a seed soaking solution whose volume is 30 times the total volume of the seeds for 12 hours, and sow within 12 hours.

[0034] Others are operated according to the conventional cabbage planting method.

[0035] The quality of the Chinese cabbage heart is significantly improved compared with that produced by the common method, the soluble solids and vitamin C content of the Chinese cabbage heart are improved, and the freshness of the Chinese cabbage heart is improved.

Embodiment 3

[0037] Prepare an aqueous solution of methyl jasmonate with distilled water, and the concentration of methyl jasmonate is 1000 μmol.L -1 .

[0038] Soak the dried cabbage seeds suitable for sowing production at room temperature in a seed soaking solution whose volume is 30 times the total volume of the seeds, and then sow immediately after 1 minute.

[0039] Others are operated according to the conventional cabbage planting method.

[0040] The quality of the Chinese cabbage heart is significantly improved compared with that produced by the common method, the soluble solids and vitamin C content of the Chinese cabbage heart are improved, and the freshness of the Chinese cabbage heart is improved.

Abstract

The invention discloses application of MeJA on aspects of vegetable preservation. MeJA can be applied before sowing of vegetable seeds for soaking process. The invention also provides a vegetable preservation soaking solution, which is the solution of MeJA, with concentration 0.001 mu mol.L<-1> to 1000 mu mol.L<-1>. In the invention, aqueous solution of MeJA in a very low concentration is used to soak seeds of cabbages, and the seeds are used to sow to produce the cabbages, thereby increasing soluble solids and content of vitamin C of the cabbages, increasing freshness of the cabbages, relieving disease rotting rate of the cabbages after being picked, proloning preserving life of the cabbages. Quality of the vegetable using the technology of the invention is higher than that produced by a common method, thereby relieving long time insect pest in a certain extent, reducing consumption of the pesticide.

Description

technical field [0001] The invention belongs to the technical field of improving the quality and freshness of vegetables in an environment-friendly environment, and in particular relates to a methyl jasmonate seed soaking solution for keeping vegetables fresh and a method for using the same. Background technique [0002] my country is the world's largest vegetable producer. my country is also the country with the largest variety of vegetables and the largest planting area in the world. Distance sales of vegetables (including sales to other provinces and exports) play a pivotal role in promoting the development of the vegetable industry and the development of foreign exchange-earning agriculture. It is also one of the effective measures to solve the "three rural" problems. Among the distance sales of vegetables, export trade is the most developed Potential, the biggest impetus to industrial development. In the current situation of economic globalization, it is difficult to ...
