Description
Technical Field
The invention relates to the technical field of vegetable chemical control, in particular to a seed production method of non-heading Chinese cabbages.
Background
The non-heading Chinese cabbage is a brassica plant of the cruciferae, commonly called as a green vegetable, is one of important green leaf vegetables in China, is used as an important economic crop, and is widely planted in the world. The non-heading Chinese cabbage has long pod bearing, more pods, full seeds and short growth cycle, and is a popular main vegetable which is favored by people in south China all the year round.
The boric fertilizer is a trace nutrient element necessary for plants, and is mainly absorbed by the plants in the form of boric acid molecules. Proper boron content in the plant body can improve the organic matter supply of each organ of the crop, ensure the normal growth of the crop and improve the maturing rate and the fruit setting rate. This element is involved in the structure and function of cell walls and membranes; thus, it is involved in many ion, metabolite and hormone transport reactions.
Methyl jasmonate (MeJA), a possible airborne signaling molecule, plays an important role in mediating plant-internal and plant-to-plant regulatory defense responses. Exogenous methyl jasmonate can increase the expression levels of some key regulatory genes, thereby improving the yield and quality of breeding.
However, the non-heading Chinese cabbage is commercialized in the seed production process, and has a series of production and application problems of low seed yield, low germination rate, weak germination vigor and the like, so that the seed production progress of the non-heading Chinese cabbage is influenced. In order to enhance the seed production yield and the seed production quality of the non-heading Chinese cabbage and improve the production benefit and the economic benefit, the invention develops a new technology for improving the seed production quality by simultaneously applying methyl jasmonate and boric fertilizer, and lays a foundation for later-stage breeding and improvement of the seed germination rate.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides a method for improving the seed production quality of non-heading Chinese cabbages, and aims to solve the technical problem that the quality of non-heading Chinese cabbages seeds is improved by combining methyl jasmonate and a boron fertilizer in the prior art.
The invention is realized by the following technical scheme:
the invention provides a method for improving seed production quality of non-heading Chinese cabbage, which comprises the following steps: and spraying a mixed solution consisting of 25 mu mol/L MeJA and 0.3% of boron fertilizer in the bud period of the non-heading Chinese cabbage.
Further, the method specifically comprises the following steps: sowing non-heading Chinese cabbage seeds in a seedling tray, transplanting the seedlings to a field for field planting when the seedlings grow to 6-7 true leaves, carrying out conventional management in the field, and spraying the mixed solution in the bud stage.
Further, the spraying position of the mixed solution is specifically the back of the leaf surface until the mixed solution is sprayed on the surface and drips.
Further, the frequency of spraying the mixed liquid is two times, and the interval time is 36 h.
Compared with the prior art, the invention has the following advantages:
1. the invention has simple operation and convenient implementation;
2. during budding, methyl jasmonate is sprayed to promote pod bearing;
3. the methyl jasmonate and the boric fertilizer are mixed and sprayed, so that the growth vigor of plants is obviously improved, and the breeding quality is greatly improved;
4. the methyl jasmonate and the boron fertilizer belong to environment-friendly reagents, have no pollution to the environment and are convenient to use.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments of the present invention, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
Sowing the seeds of the non-heading Chinese cabbage WS-1 in a seedling cultivation hole tray, and transplanting the seedlings of the non-heading Chinese cabbage to a field for field planting when the seedlings grow to 6-7 true leaves, wherein conventional management is carried out in the period. Respectively spraying 0 mu mol/L, 15 mu mol/L, 25 mu mol/L, 35 mu mol/L MeJA, 0.20%, 0.30%, 0.40% boron fertilizer, 15 mu mol/L + 0.2%, 15 mu mol/L + 0.3%, 15 mu mol/L + 0.4%, 25 mu mol/L + 0.2%, 25 mu mol/L + 0.3%, 25 mu mol/L + 0.4%, 35 mu mol/L + 0.2%, 35 mu mol/L + 0.32%, 35 mu mol/L + 0.4% MeJA + boron fertilizer combined liquid on the back of leaf surfaces of non-heading Chinese cabbages in the bud stage, the flower-opening stage and the full-bloom stage, spraying 3 times, treating every 10 plants once, treating 30 plants at each concentration, spraying clear water as a control, and spraying water on the surfaces until water drops on the surfaces. And (3) after the non-heading Chinese cabbages blossom and pod, collecting seeds, fully treating the seeds, storing the seeds in a low-temperature seed storage warehouse, and calculating the thousand seed weight, the germination rate and the germination vigor of the seeds, wherein the experimental results are shown in tables 1-3.
Table 1 shows the influence of different treatments in bud period on the seed production quality of non-heading Chinese cabbage seeds
TABLE 2 influence of different treatments on seed production quality of non-heading Chinese cabbage seeds in flowering period
TABLE 3 influence of different treatments in full-bloom stage on seed production quality of non-heading Chinese cabbage
According to the method, the MeJA + boron fertilizer combined liquid with 25 mu mol/L + 0.3% is sprayed in the bud period, so that the seed quality is obviously improved. The thousand grain weight, the germination rate and the germination vigor of the non-heading Chinese cabbages are improved to different degrees by independently applying MeJA and independently applying boron fertilizer, and the thousand grain weight, the germination rate and the germination vigor of the Chinese cabbages are improved to certain extent by mixedly applying MeJA and the boron fertilizer; in addition, the MeJA + boron fertilizer composite liquid sprayed by 25 mu mol/L + 0.3% in the bud period is improved compared with the MeJA + boron fertilizer composite liquid in the flowering period and the full-bloom period. The seed production quality of the non-heading Chinese cabbage can be effectively improved by spraying the 25+ 0.3% MeJA + boron fertilizer composition liquid in the bud stage.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
