Description

Technical Field

[0001] The invention relates to the technical field of tobacco planting, in particular to an irrigation device for a tobacco seedling greenhouse. Background Art

[0002] Tobacco is an annual herb of the genus Nicotiana in the family Solanaceae. The leaves are oblong-lanceolate, lanceolate, oblong or ovate, gradually pointed at the apex, narrowed at the base to become ear-shaped and semi-amplexicaulous, with inconspicuous petioles or wing-shaped; the inflorescence is conical, the calyx is tubular or tubular-bell-shaped, the lobes are triangular-lanceolate, the corolla is funnel-shaped, light yellow, light green, red or pink, with yellow at the base; the capsule is ovoid or elliptical, almost as long as the persistent calyx; the seeds are round or broadly oblong, brown; the flowering and fruiting period is summer and autumn.

[0003] Tobacco is grown in greenhouses during the seedling stage, and most of them adopt a floating seedling method. Floating seedling irrigation is an innovative seedling method that combines soilless cultivation technology. It uses special foam plug trays to allow plants to grow on the water surface, and at the same time supplies the plants with the water and nutrients they need through hydroponic solution. However, since the foam plug trays are usually in a non-fixed floating state in the pool, and the nutrients in the water in the pool are easily precipitated at the bottom of the pool after being left stationary for a long time, it is difficult for the roots of the seedlings to absorb nutrients in the water, thereby affecting the growth rate and quality of the tobacco seedlings. Therefore, in view of the above-mentioned deficiencies, the present invention makes the following improvements. Summary of the invention
