Example Embodiment
[0042] Embodiment 1: The technique of burying paulownia tree seedlings in this embodiment includes the following steps:
[0043] 1), site selection and site preparation
[0044] Choose the nursery land with flat terrain, convenient irrigation and drainage, deep soil layer, fertile soil, and a place where the groundwater level is 1.5-2.0 meters leeward and sunny; after the nursery land is selected, deep ploughing is carried out before autumn and early winter to promote soil weathering and freeze overwintering pests. After thawing in the spring of the second year, conduct shallow ploughing, fine raking, and leveling the land; before shallow ploughing and fine raking, apply 2500kg of decomposed farmyard manure per mu, 25kg of NPK compound fertilizer, 2kg of 3% phoxim granules, and sulfurous acid Iron 10kg;
[0045] 2), select seed roots
[0046] The seed roots used for raising seedlings should be two-year-old seedling roots, with a root length of 12 cm and a bulk thickness of 1.5-2.5 cm...
Example Embodiment
[0079] Embodiment two:
[0080] The technique of burying the roots of the paulownia tree in this embodiment includes the following steps:
[0081] 1), site selection and site preparation
[0082] Choose a place where the nursery land is flat, convenient for irrigation and drainage, deep soil, fertile soil, and the groundwater level is 1.8 meters away from the sun; after the nursery land is selected, deep ploughing is carried out in autumn and early winter to promote soil weathering and freeze overwintering pests. Second After thawing in spring in the spring, carry out shallow ploughing, fine raking, and leveling the land; before shallow ploughing and fine raking, apply 3200kg of decomposed farmyard manure per mu, 35kg of NPK compound fertilizer, 2.5kg of 3% phoxim granules, and ferrous sulfate 12kg;
[0083] 2), select seed roots
[0084] The seed roots used for raising seedlings are selected as 2-year-old seedling roots, with a length of 16 cm and a thickness of 2 cm;
[0085] 3) Seed...
Example Embodiment
[0117] Embodiment three:
[0118] The technique of burying the seedlings of paulownia trees includes the following steps:
[0119] 1), site selection and site preparation
[0120] Choose the nursery land with flat terrain, convenient irrigation and drainage, deep soil layer, fertile soil, and a place where the groundwater level is 1.5-2.0 meters leeward and sunny; after the nursery land is selected, deep ploughing is carried out before autumn and early winter to promote soil weathering and freeze overwintering pests. After thawing in the spring of the second year, conduct shallow ploughing, fine raking, and leveling the land; before shallow ploughing and fine raking, apply 4,500 kg of decomposed farmyard manure, 45 kg of nitrogen, phosphorus and potassium compound fertilizer, 3 kg of 3% phoxim granules, and sulfurous acid per mu. Iron 15kg;
[0121] 2), select seed roots
[0122] The seed roots used for seedling cultivation should be 2-year-old seedling roots, with a length of 20 cm a...
