Description

Technical Field

[0001] The invention relates to the technical field of plant cultivation, in particular to a heat-insulating germination substrate and a germination method thereof. Background Art

[0002] Direct seeding refers to the act of sowing dry seeds directly into the soil without artificial germination and seedling raising, so that the seeds germinate in the soil, thereby reducing the number of transplanting steps. However, the conditions required for seed germination are relatively harsh. Low or high temperature, low or high humidity, will all lead to the situation where the seeds do not germinate. Direct seeding makes it difficult to regulate soil conditions, making it impossible to predict the germination of seeds. In addition, transplanting seeds after germination can screen strong seedlings and remove unqualified seedlings, and the planting density can be controlled during planting, thereby reducing seed waste. Therefore, direct seeding of seedlings is currently the most commonly used method for plant cultivation.

[0003] Germination, namely providing the most ideal germination environment for seeds, allowing seeds to sprout as soon as possible, and making seedlings more robust. At present, germination is usually to place seeds in a germination matrix, and then place the matrix and seeds together indoors, and promote seed germination by artificially controlling the temperature and humidity of the external environment. However, the seeds are directly in contact with the germination matrix, and it is difficult to effectively ensure the temperature and humidity in the germination matrix by regulating the temperature of the external environment, and this method is complex to manage and consumes a lot of energy, which undoubtedly increases the planting cost. Therefore, it is urgent to provide a germination matrix and germination method that are simple to manage, have low energy consumption, are low in cost, and have a fast germination speed. Summary of the invention

[0087] Example 3

[0088] Bacillus licheniformis, Acetobacter acetobacter, Aspergillus oryzae, Trichoderma reesei, and yeast were mixed in a ratio of 3:3:2:2:3 to prepare a culture medium with a viable count of 80.0 × 10 8 The compound bacterial agent is dissolved in water to prepare a 12% concentration of decomposing bacterial liquid.

[0090] Comparative Example 1

[0091] Based on Example 1, this comparative example explored the bacterial species in the composite bacterial agent, the concentration of the decomposed bacterial solution, and the types of leaves. Among them, the bacterial agent formula is as shown in Table 1, set as Group 1, 2, and 3; the concentration of the decomposed bacterial solution is adjusted to 20%, set as Group 4; the locust leaves are replaced with pine needles, set as Group 5. Other operations are the same as Example 1.

[0092] Table 1 Compound bacterial agent strain formula

[0093] Group 1 Group 2 Group 3 Bacillus licheniformis - 2 2 Bacillus subtilis 2 - - Acetobacter 2 - 2 Lactic acid bacteria - 2 - Aspergillus oryzae 1 1 - Aspergillus niger - - 1 Trichoderma reesei 1 1 1 Yeast 2 2 2

[0094] Test Example 1

[0095] The performance of the germination substrate prepared by the above Examples 1 to 3 and Groups 1 to 5 in Comparative Example 1 was investigated using the germination time of Polygonatum cyrtonema seeds and the germination rate after one week of germination as indicators. The specific process is as follows:

[0096] (1) In October, harvest plump, yellow-skinned Polygonatum sibiricum fruits, bag them, and seal the bags. After the flesh undergoes anaerobic respiration, heats up, and rots, soak them in water to separate the seeds and the flesh / juice. Ensure that the flesh on the seed surface is completely washed off, and dry the surface moisture.

[0097] (2) Take 98% fludioxonil, mix them in a ratio of 10 μl fludioxonil: 5 kg water, then add gibberellin to make the concentration of gibberellin 150 mg / ml, and obtain a mixed solution. Soak the polygonatum seeds dried in step (1) in the mixed solution for 40 minutes, and then coat the seed epidermis with a layer of carbendazim powder in a ratio of 100 g carbendazim powder: 10 kg seeds. Carbendazim and gibberellin have a dormancy-breaking effect on polygonatum seeds and can shorten the germination period of seeds.

[0098] (3) The seeds treated in step (2) are mixed with the germination substrates prepared above in a mass ratio of 1:4 to obtain a seed mixture.

[0099] (4) Use a fiber blanket as a base, and use the leaves soaked in the fermentation liquid of the corresponding group to spread on the fiber blanket with a thickness of 12 cm, wrap it around with fiber blanket, and then lay a layer of plastic mesh with a pore size of 100 mesh to make a germination bed. Spread the seed mixture evenly on the plastic mesh of the germination bed with a thickness of 10 cm, cover the seeds with a plastic mesh with a pore size of 100 mesh, and then cover it with a 12 cm thick layer of leaves soaked in the fermentation liquid of the corresponding group. After this treatment, the upper and lower layers of leaves of the seed mixture ferment and generate heat, which can ensure the temperature for seed germination. Then wait for germination.

[0100] The germination time of each group and the germination rate after one week of germination were counted, and the results are shown in Table 2. Among them, the germination substrate of Example 1 was used to treat the Polygonatum cyrtonema seeds. The germination state of the seeds after one week of germination was as follows Figure 1 shown.

[0101] Table 2 Germination time and germination rate of each group after one week of germination

[0102] Group Germination time Germination rate Example 1 35 days 96.5％ Example 2 37 days 95.7％ Example 3 38 days 95.9％ Group 1 45 days 78.3％ Group 2 49 days 72.1％ Group 3 44 days 82.4％ Group 4 41 days 45.7％ Group 5 50 days 82.5％

[0103] As can be seen from Table 2, the germination matrix of Examples 1 to 3 can significantly shorten the germination time of Polygonatum sibiricum seeds and improve the germination rate. After Group 1 replaced Bacillus licheniformis, Group 2 replaced Acetobacter, and Group 3 replaced Aspergillus oryzae, the germination time of Polygonatum sibiricum seeds was significantly prolonged, and the germination rate was reduced. After Group 4 increased the concentration of the decomposed bacteria solution, the germination time was not significantly different from that of Examples 1 to 3, but its germination rate was significantly reduced. Subsequent testing showed that the temperature of the germination bed reached 42.3°C during the germination process. It is speculated that Group 4 had a lower germination rate due to the high germination temperature. After Group 5 replaced Sophora japonica leaves, the germination time was prolonged and the germination rate was reduced compared with Examples 1 to 3. It shows that the germination matrix of Examples 1 to 3 of the present invention can significantly shorten the germination time of Polygonatum sibiricum seeds and improve the germination rate.

[0104] Test Example 2

[0105] This test example explored the germination method of Polygonatum cyrtonema seeds. Polygonatum cyrtonema seeds treated according to steps (1) to (3) of Test Example 1 were sown outdoors, forming Group 7; Polygonatum cyrtonema seeds treated according to steps (1) to (2) of Test Example 1 were sown outdoors, forming Group 8. The germination time and germination rate of each group after one week of germination were counted, and the results are shown in Table 3. Among them, the germination status of seeds in Group 8 after one week of germination is as follows Figure 2 shown.

[0106] Table 3 Germination time and germination rate of each group after one week of germination

[0107] Group Germination time Germination rate Example 1 35 days 96.5％ Group 7 52 days 87.7％ Group 8 60 days 52.4％

[0108] As can be seen from Table 3, by using the germination matrix and germination method of the present invention, the germination time is 35 days and the germination rate is 96.5%; by only using the germination matrix of the present invention and direct sowing Polygonatum cyrtonema seeds outdoors, the germination time is 52 days and the germination rate is 87.7%; while by directly direct sowing Polygonatum cyrtonema seeds outdoors, the germination time reaches 60 days and the germination rate is only 52.4%. This shows that compared with direct sowing Polygonatum cyrtonema seeds outdoors, the germination matrix of the present invention combined with the germination method of the present invention can greatly shorten the germination time and improve the germination rate. Using only the germination matrix of the present invention can also significantly shorten the germination time and improve the germination rate. In addition, from Figure 1 and Figure 2 It can be seen that the germination matrix of the present invention combined with the germination method of the present invention can significantly enhance the vigor of seed buds than that of seed buds directly sown outdoors.

[0109] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
