Example Embodiment
[0029] Example 1: Use a degradable bowl made of straw, the height of the bowl is 150mm, the diameter of the mouth is 170mm, a row of holes with a diameter of 3mm and an interval of 60mm are made at one-third of the height of the bowl, and a 50mm hole is made at the center of the cover. Hole, fill 30 mesh zeolite in one-third of the height of the pot body, fill the zeolite with a 1:2 mixture of compost and local soil, sow Caragana seeds, fill the nutrient pot, and water it. The test results show that compared with the control (local desertified soil), the water content is increased by 13%, and the survival rate is increased by 12%.
Example Embodiment
[0030] Example 2: Use a degradable bowl made of degradable resin, the height of the bowl is 200mm, the diameter of the mouth is 220mm, a row of holes with a diameter of 3mm and an interval of 60mm are made at one-third of the height of the bowl, and a row of holes is made at the center of the cover. A 50mm hole is filled with 20 mesh peat in one-third of the height of the bowl, and the peat is filled with a 1:4 mixture of compost and local soil. After sowing the astragalus seeds to fill the nutrient bowl, water it. The test results show that compared with the control (local desertified soil), the water content is increased by 6%, and the survival rate is increased by 13%.
Example Embodiment
[0031] Example 3: Degradable bowl made of biodegradable resin, the height of the bowl is 150mm, the diameter of the mouth is 170mm, a row of holes with a diameter of 3mm and an interval of 60mm are made at one-third of the height of the bowl, and a row of holes is made at the center of the cover. Fill a 50mm hole with 80 mesh vermiculite in one-third of the height of the pot body. Fill the vermiculite with a 1:6 mixture of compost and local soil. After sowing Caragana seeds, fill the nutrient pot and water it. The test results show that compared with the control (local desertified soil), the water content is increased by 4.5%, and the survival rate is increased by 9%.
