Description

Technical Field

[0001] The invention relates to the technical field of ecological restoration and afforestation, and in particular to a bulb preparation process and a sowing method for ecological restoration. Background Art

[0002] Land degradation, especially in arid and semi-arid regions, poses a major challenge to ecological restoration. Harsh conditions in these regions, such as low rainfall, poor soil quality, and high temperatures, severely hamper the restoration of natural vegetation. Traditional afforestation and planting methods often fail to achieve the desired results, with low germination success and survival rates. It is therefore imperative to develop a seeding method that can improve the germination success and survival rate of plants in land degraded environments in arid and semi-arid regions. Summary of the invention

[0033] A bulb sowing method for ecological restoration, specifically: planting the bulbs prepared in this embodiment in the soil by inserting, controlling the inserting depth to 30 cm, and the inserting row spacing and plant spacing to 2m×2m.

[0034] Test Example 1 According to the bulb preparation process and sowing method in Examples 1-12, sowing was carried out in the same area with an annual rainfall of less than 400 mm. The number of bulbs used in sowing was 200. The total number of germinated bulbs at 1d, 2d, 3d, 4d, 5d, 6d, 9d, 12d, and 15d after sowing was counted, the germination rate of the bulbs 15d after sowing was calculated, and the survival rate of the bulbs 30d after sowing was counted. The statistical results are as follows:

[0035] Comparing the results of Example 1 with those of Examples 7-9, the germination rate and survival rate of Example 9 were the best, and comparing the results of Example 4 with those of Examples 10-12, the germination rate and survival rate of Example 12 were the best. This shows that the germination rate and survival rate of wet-frozen bulbs were the best. After analysis, the reasons are as follows: 1. Frozen bulbs can gradually release water when thawed, providing a certain source of water for seeds. Once the frozen bulbs are planted by air or inserted into the soil, they begin to thaw, and the water in the bulbs is slowly released into the seeds, ensuring that the seeds have enough water to germinate even in extremely dry conditions; 2. The protective shell of the wet frozen bulbs will gradually decompose, allowing the seedlings to obtain the nutrients stored in the bulbs. This slow decomposition process ensures that the seeds in the bulbs are provided with continuous nutritional support in the early stages of growth, even in nutrient-poor soils; 3. After freezing treatment, the metabolic rate of seeds is slowed down to a certain extent, thereby extending the shelf life of seeds. In contrast, wet bulbs stored in a humid environment are more susceptible to microorganisms, causing seeds to rot or mold, thus affecting bulb germination; 4. After freezing, the water inside the bulb forms an ice crystal structure, which enhances the physical strength of the bulb. This makes the wet-frozen bulb less likely to break when dropped from a high altitude, thus increasing the success rate of aerial seeding. 5. After freezing treatment, the seeds can enter a dormant state. After sowing, the bulbs will gradually break dormancy and begin to germinate. Therefore, freezing treatment plays a role in regulating the physiological state of seeds, which helps the seeds to better adapt to the environment and germinate after sowing; 6. After freezing treatment, the appropriate humidity is preserved. The wet-frozen bulbs are easier to absorb water and nutrients after sowing, which is beneficial to seed germination. Once the seedlings grow stably, they can obtain moisture from the surrounding soil, thereby increasing their chances of long-term survival.

[0036] In addition, it can be seen from the above data that if nutrients are not added, although there will be a certain impact, the impact is not significant because the matrix, minerals and organic matter can provide some nutrients.

[0037] Unless otherwise specified, all percentages used in the present invention are by mass.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
