However, the inventors have found that because the fertilizer is in contact with the seeds or is relatively close to the seeds, once it is improperly applied, it will cause burnt seedlings, rotten seeds and lack of seedlings. Add less fertilizer

Embodiment 1

[0049] (1) Select the mainstream varieties of Hongyue, Tongdelai, Heitian Wucun, Leikende, Hongyu, Royal Red and Mendel carrot seeds as experimental materials.

[0050] (2) Put the carrot seeds into the cold plasma seed treatment equipment, and carry out non-ionizing radiation treatment on the carrot seeds for 8-20s under the treatment power of 1-300W.

[0051] (3) The germination rate test was carried out on the treated carrot seeds.

[0052] Compared with the same batch of carrot seeds that have not undergone any treatment and are selected in step 1, the germination index and vigor index of the treated carrot seeds are improved. The calculation formulas of germination index and vigor index are as follows:

[0053] Germination rate (GR2)=n / N*100% In the formula, n is the number of germinations in 14 days, and N is the total number of seeds.

[0054] Vitality index (VI)=GI*S, in the formula, GI is the germination index (GI=∑Gt / Dt, and in the formula, Gt is the number of seed...

Embodiment 2

[0062] (1) Select the mainstream varieties of Hongyue, Tongdelai, Heitian Wucun, Leikende, Hongyu, Royal Red and Mendel carrot seeds as experimental materials.

[0063] (2) Put the carrot seeds into the cold plasma seed treatment equipment, and use the processing power of 130W to treat the carrot seeds with non-ionizing radiation for 16s.

[0064] (3) The processed carrot seeds are vacuum-packed, and a third party is entrusted to conduct professional colony detection.

[0065] With the corresponding same batch of carrot seeds that have not been processed and selected in step 1 as a control, the effect of cold plasma treatment on the total number of carrot seed colonies is shown in Table 2:

[0066] Table 2: The effect of cold plasma treatment on the total number of colonies of carrot seeds

[0067]

[0068] Note: ① Detection limit: 10CFU / g

[0069] As can be seen from Table 2, the total number of colonies of carrot seeds of different varieties treated with cold plasma is ...

Embodiment 3

[0071] The treatment method (1), (2) is the same as in Example 2, the difference is that after the treatment, the carrot seeds are pelletized, and for no contact with fungicides, the pelletized powder is added with fulvic acid organic bacterial fertilizer according to the proportion of 0.5%. .

[0072] ① The effects of cold plasma treatment and pelletized carrot seed field emergence and seed consumption are shown in Table 3:

[0073] Table 3: Field emergence and seed consumption of pelleted carrot seeds

[0074]

[0075] It can be seen from Table 3 that compared with the control, the pelleted carrot seeds can increase the field emergence rate, and the field emergence rate of the pelleted carrots increases by 5.47-8.05%, and the highest field emergence rate is 8.05% for Kuroda Gosun ;With a treatment power of 130W and a treatment time of 16s, after cold plasma treatment and pelletization, the seedling emergence rate in the field increased by 10.78-15.68%, and the highest pe...

Abstract

The invention provides a seed treatment method for increasing the carrot root swelling speed and application of the seed treatment method, and belongs to the technical field of agricultural quality improvement. According to the seed treatment method, carrot seeds are treated through a cold plasma technology to obtain sterile healthy seeds with the increased germination rate, the carrot seeds withthe increased root swelling speed are obtained through pelleting treatment, and the defects that existing carrots are low in germination rate, fleshy roots are prone to forking and the like are overcome. According to the method and process operation provided by the invention, the germination rate of the carrots is increased, no bactericidal agent is needed for pelleting, the cost is reduced, and the environment is optimized; fulvic acid organic bacterial manure is used as pelleting powder for pelleting treatment, and a microenvironment more suitable for growth of the carrots is obtained; and meanwhile, the pelleting treatment and the cold plasma non-ionizing radiation effect have a synergistic effect, the treated carrots emerge uniformly in a field, fleshy root bifurcations are reduced, and the commodity rate is increased, so that the method has good practical popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of agricultural quality improvement, and in particular relates to a seed treatment method for improving the root swelling speed of carrots and an application thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Carrot (Daucus carota L.var.sativa Hoffm.), also known as red radish or radish, is a variety of wild carrot (Daucus carota L.var.carota), which has a low germination rate due to the formation and structure of carrot seeds , generally only 60%-70%, and the germination is not neat, so the early growth of the group is often uneven. The harvested seeds can generally only be used in the autumn sowi...
