Seedling growing belt and seedling growing method for stevia rebaudiana

Abstract

The invention provides a seedling growing belt and a seedling growing method for stevia rebaudiana. A paper strip is soaked in a prepared vegetable gum solution, taken out and aired to 30% humidity, so that the seedling growing belt is obtained. The seedling growing method comprises the steps of shearing cutting slips from stock plants which grow robustly; placing taken-out seedlings between the two seedling growing belts, and adjusting the spacing between the seedlings according to the seedling growing density requirement; and integrally cutting the seedling growing belts and the seedlings ina seedling growing tray paved with soil in rows, watering enough water, and performing seedling growing management in the later period. According to the seedling growing method, seedling separation and seedling arrangement in the seedling growing link are completed outside the seedling growing tray, the seedling growing quality and working efficiency of the seedling growing tray can be greatly improved, and meanwhile, conditions are created for mechanical transplanting.

Description

technical field [0001] The invention relates to a stevia seedling raising belt and a seedling raising method, belonging to the technical field of agriculture. Background technique [0002] Stevia is a perennial herb of Compositae. The leaves contain inulin, which is 150 to 300 times sweeter than sucrose, and only 1 / 300 of the calories contained in sucrose. It is the sweetest natural sugar known so far. It is known as the "King of Plant Sugar" in the world. Because of its high safety and no side effects, it has become the "third sugar source" in China after sucrose and beet sugar. At present, stevia products are widely used in food, medicine, daily chemical industry and other industries. [0003] In recent years, due to the improvement of consumers' awareness of pure natural food, the demand for stevia sugar has increased from 4000t in 2010 to 6800t in 2018, increasing at a compound rate of 20.0% every year, and the planting area of ​​stevia is also increasing year by year....

AI Technical Summary

Problems solved by technology

However, the cutting seedling breeding technology is not easy to master, and the links are trivial and complicated. At the same time, there is no suitable cutting machine, and the seedlings are raised by manual cuttings. The quality of the seedlings is poor and the labor cost is high.

[0004] Due to the high density of Stevia rebaudiana cuttings and the soft substrate, the seedlings are not fixed firmly in the soil during traditional artificial cutting seedlings. At the same time, when continuous artificial cutting seedlings are operated, operations in a small space are likely to cause the previously cut seedlings to be dragged and moved. , resulting in poor seedling uniformity and inconsistent soil depth, which further led to a significant increase in the rate of seedling picking and seedling injury in mechanical transplanting
