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...
