Description

Technical Field

[0001] The utility model belongs to the field of tobacco planting equipment, and specifically relates to a tobacco seedling raising shed for preventing seedlings from burning. Background Art

[0002] Tobacco is a plant of the genus Nicotiana in the Solanaceae family. It is an annual or limited perennial herb, covered with glandular hairs throughout; the root is sturdy. The stem is 0.7-2 meters high, and the base is slightly lignified. The leaves are oblong-lanceolate, lanceolate, oblong or ovate, with a gradually pointed apex and a gradually narrowed base until the stem becomes ear-shaped and semi-amplexicaulous. The inflorescence is terminal, conical, and multi-flowered; the pedicel is 5-20 mm long. The capsule is ovate or oblong, about the same length as the persistent calyx. The seeds are round or broadly oblong, about 0.5 mm in diameter, and brown. It blooms and bears fruit in summer and autumn.

[0003] During the tobacco floating seedling cultivation process, root rot often occurs before the tobacco seedlings are transplanted. About 50 days after the one-stage seedling tray cultivation or about 10 days after the two-stage seedling throwing cultivation, root rot often occurs, affecting the survival rate of the tobacco seedlings after transplanting and the co-infection of other diseases, resulting in a high rate of seedling abandonment, causing economic losses to the seedling owners and tobacco farmers. In addition to the root rot that often occurs before the tobacco seedlings are transplanted, tobacco seedlings may also burn. Because the seedling environment temperature is too high, after the culture solution is left for a period of time, fertilizer will precipitate on the surface of the culture soil on the seedling bed, resulting in excessive concentration on the surface of the culture soil, causing seedling burn. Tobacco seedlings are generally carried out in seedling sheds. Therefore, it is very necessary to design and produce a seedling shed that can reduce the internal temperature of the seedling shed.

[0004] The utility model patent with the patent number of 202322709308.0 discloses a tobacco seedling shed, which includes a closed seedling shed body and a work shed. The seedling shed body is provided with a shed door that can be opened and closed. The work shed is provided with a shoe disinfection pool, which is located at the inner edge of the work shed and correspondingly arranged at the entrance of the shed door. The work shed is constructed by embedded pipes, support pipes, arch rods, crossbeams, tie rods and rainproof tarpaulins. The embedded pipes are fixed on the flat ground, the support pipes are sleeved on the embedded pipes, the arch rods are fixedly connected above the support pipes, the crossbeams are fixedly connected between the arch rods, the tie rods are fixedly connected to the arch rods, and the rainproof tarpaulins are covered above the tie rods. The above technical scheme can not only provide sunshade and rainproof, but also standardize management, reduce the shedding of seedling substrates, and better ensure the effect and work efficiency of seedling cultivation. However, the seedling shed is not provided with cooling equipment. When the temperature in the seedling shed is too high, the seedlings may be burned. Utility Model Content
