Assembled tobacco seedling culturing system

Abstract

The invention discloses an assembled tobacco seedling culturing device and relates to an assembled tobacco seedling culturing system. The assembled tobacco seedling culturing system is formed by a plurality of seedling culturing cylinders, assembling parts and seedling culturing ground substances, wherein each seedling culturing cylinder is a closed cylinder formed by a cylinder side, a cylinder cover and a cylinder bottom. Each seedling culturing cylinder is filled with the seedling culturing ground substances. The seedling culturing cylinders are connected through the assembling parts to form a mutually-connected seedling culturing cylinder group as a seedling culturing operating unit. The assembled tobacco seedling culturing system has the following advantages: (1) the assembled tobacco seedling culturing system remarkably decreases seedling culturing procedures and has obvious effects of reducing working time and lowering cost; (2) the assembled tobacco seedling culturing system provides good growing space for root systems of tobacco seedlings, so the root systems of the cultured tobacco seedlings are more thriving and the drought resistance ability of the tobacco seedlings is stronger; (3) the strong tobacco seedlings can be cultured on the basis of the thriving root systems of the tobacco seedlings in the seedling culturing cylinders; (4) the seedling culturing process is easy to manage; (5) the tobacco seedlings in each seedling culturing cylinder are transplanted separately, the root systems of the tobacco seedlings will not be damaged in the process of lifting the seedlings, and the revival time of the tobacco seedlings can be shortened after the seedlings are transplanted so as to accelerate early and fast growing of the tobacco seedlings. The assembled tobacco seedling culturing system is suitable for tobacco cultivation.

Description

technical field [0001] The present invention relates to the cultivation of tobacco, in particular to the cultivation of tobacco seedlings. Background technique [0002] At present, flue-cured tobacco seedlings are mostly raised by floating seedlings. In the process of use, it is necessary to purchase floating trays and seedling substrates first, then use agricultural film and hollow bricks to make seedling pools, fill the floating tray substrates with machines or manually, and then sow seeds. Seedlings are raised in deep water seedling ponds. This seedling raising method has the following problems: First, the cost of seedling raising is high, and the cost is mainly generated in the purchase of seedling raising floating trays, seedling raising substrates, agricultural film and hollow bricks, etc. In addition, the labor cost of seedling raising is relatively high; There are many processes such as seedling preparation, seedbed making, traying, sowing, seedling shed making, et...

AI Technical Summary

Problems solved by technology

This seedling raising method has the following problems: First, the cost of seedling raising is high, and the cost is mainly generated in the purchase of seedling raising floating trays, seedling raising substrates, agricultural film and hollow bricks, etc. In addition, the labor cost of seedling raising is relatively high; Seedling preparation, seedbed making, traying, sowing, seedling shed making and many other processes, the seedling efficiency is low

The third is that although the tobacco seedlings cultivated by floating seedlings have many root systems, most of them are invalid roots, which have poor drought resistance and transplanting performance, and the time for seedlings to return after transplanting is long; the fourth is that the tobacco seedlings cultivated are difficult to grow into strong seedlings; More, in arid areas, the source of water for seedlings limits the development of seedlings; Sixth, the production of seedling ponds is relatively high, and the bottom level of the box must be guaranteed
