In the northern region, some growers will bury a mineral water bottle under the root of the tree when planting saplings, which mainly has the following purposes:
1.Retain moisture: The climate in the north is dry, and soil moisture evaporates quickly. Burying a mineral water bottle at the root of the sapling can slowly release the water in the bottle into the soil, keep the soil moist, and facilitate the growth of the sapling.
2.Provide nutrients: Mineral water bottles can be filled with an appropriate amount of nutrient solution or fertilizer, and as the mineral water bottles slowly dissolve, these nutrients will gradually be released into the soil to provide sufficient nutrients for the saplings.
3.Protect the root system: During the planting process, the root system of the seedling may be damaged. Burying a mineral water bottle at the root can provide a protective layer for the root system of the sapling, reduce the influence of external factors on the root system, and help the growth of the sapling.
4.Improve the survival rate: By burying the mineral water bottle under the root of the tree, it can provide a relatively stable growth environment for the sapling, which is conducive to improving the survival rate of the sapling.
It should be noted that when burying mineral water bottles, the depth and position of the bottles should be appropriate so as not to affect the normal growth of the saplings. At the same time, it is necessary to regularly check the dissolution of mineral water bottles and replenish water and nutrients in time.
