Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of plant seedling technology, more particularly to a water control device for biomass seedling tray seedling technology. BACKGROUND

[0002] Seedling is a method of sowing in the room or greenhouse, and then transplanting seedlings to the field for cultivation after the seedlings grow out, and the seedling method determines the sowing period, sowing quantity, transplanting and market time, and good seedling technology can lay a good foundation for cultivating strong seedlings, enhancing disease resistance and stress tolerance, and high quality and high yield. At present, common seedling methods include traditional seedling methods such as seedling tray and nutrient pot, and the floating seedling method introduced in recent years, wherein the floating seedling method refers to a seedling method in which a foam plug floating in a seedling pool is filled with light seedling substrate, seeds are sown in the substrate, and seedlings grow in the seedling substrate and can absorb water and nutrients from the substrate and the nutrient solution or water in the seedling pool. The floating seedling method has the advantages of reducing the labor for transplanting, saving seedling land, facilitating tobacco seedling management, being conducive to cultivating strong seedlings, and improving the seedling rate.

[0003] However, the conventional floating seedling method has the following technical problems: in the seedling process, the nutrient solution needs to be added to the seedling pool in multiple times, and the water in the seedling pool contains a large amount of unused nutrient solution after the seedling is completed, resulting in a large amount of waste water. The foam seedling tray has the problems of large amount, difficult cleaning and high risk of environmental pollution. In view of the above problems, the team has developed a fully degradable straw biomass seedling tray using fungi and agricultural and forestry by-products as raw materials. This technology can realize the functions of drought resistance, early root growth and resistance improvement in the field, and achieve the goals of pollution reduction and synergistic effect in the seedling link.

[0004] The wet seedling technology combined with the degradable biomass seedling tray requires the substrate to maintain a cycle process of "dry-wet, dry-wet alternation", promote the full growth of lateral roots, and form an integrated structure of plant root system-substrate-biomass seedling tray. After transplanting, the biomass material is directly degraded and converted into organic fertilizer, so that the plant seedlings have strong resistance and early growth after being transplanted to the field. The degradable biomass seedling tray requires the seedbed to be wet in the early stage and dry in the later stage, and the water depth is 1-2 cm in the early stage. In the later stage, the water and nutrients are supplied manually, and the lateral roots are developed without aquatic roots, which truly achieves the standard of strong and good seedlings. However, in the current management process, manual observation and addition of nutrient solution are often required to prevent seedlings from drying out or lacking nutrients, which leads to poor development. However, this method is difficult to accurately control the water level of the seedling pool, and increases the labor cost.

[0005] Therefore, it is necessary to further improve the existing technology. UTILITY MODEL CONTENTS
