Problems solved by technology

[0004] However, there are also some problems in the existing floating seedling cultivation: first, the amount of floating seedling substrate is large, the cost is high, and it cannot be reused; the second is that the main component of the substrate is peat, and a large amount of natural resources such as peat are consumed every year. The damage to the ecological environment has been caused; the third is that peat resources are limited, and the price of substrates continues to rise, which is generally unbearable for tobacco farmers and the cost of cultivation is high

Abstract

The invention relates to a float seedling breeding master disc made of polystyrene foam plastics. The float seedling breeding master disc is 3.2-3.5cm in thickness. At least two conical through holes are distributed in the float seedling breeding master disc. The bottom diameter of each through hole is 0.3-0.5cm, and the top diameter thereof is 1.5-1.7cm. The distance between every two conical through holes is 2.2cm. The invention further relates to a float seedling breeding device and a tobacco seedling breeding method. The float seedling breeding master disc has the advantages that the float seedling breeding master disc is thin and the conical through holes are small in diameter; when the float seedling breeding master disc is used, substrate use amount is low and substrate utilization rate is high, and cost is lowered correspondingly.

Description

technical field [0001] The invention relates to the field of floating seedling cultivation, in particular to a floating seedling raising mother tray, a floating seedling raising device and a method for cultivating tobacco seedlings. Background technique [0002] Floating seedlings, also known as floating planting, is a method that floats foam trays with light seedling substrates on the water surface, seeds are sown in the substrates, seedlings take root and grow in the seedling substrates, and can absorb water from the substrates and water beds. and nutrient raising methods. Floating seedlings can cultivate disease-free seedlings of the right age and stems. Compared with traditional seedling cultivation methods, it has the advantages of reducing labor for transplanting, saving land for seedling cultivation, facilitating tobacco seedling management, conducive to cultivating strong seedlings, and improving seedling success rate. Floating seedlings is an agricultural planting ...
