Long-distance transportation method for stevia rebaudiana seedlings

Abstract

The invention relates to the technical field of agricultural planting, in particular to a long-distance transportation method for stevia rebaudiana seedlings. The method comprises the following steps of 1, weighing perlite, wood bits, wheat bran, furnace slag, lime, excrement, walnut shells and stevia rebaudiana powder separately, conducting pulverization, mixing the materials to be uniform, and adding a proper amount of water, so that a culture medium is obtained; 2, preparing the stevia rebaudiana seedlings; 3, uniformly laying the culture medium in culture box bodies in a scattering manner, and uniformly arraying the seedlings on the culture medium, wherein the seedlings are distributed in rows, the row spacing is 5-10 cm, and the distance between every two adjacent seedlings in each row is 1-3 cm; 4, mounting the culture box bodies where the seedlings are arrayed onto a transportation vehicle in an ordered manner; and 5, randomly checking the condition of the seedlings in the box bodies every 3-4 hours in the transportation process. By means of the long-distance transportation method for the stevia rebaudiana seedlings, the survival rate, after long-distance transportation is completed, of the stevia rebaudiana seedlings is greatly increased, and expanding of the stevia rebaudiana planting area and application and popularization of new varieties are guaranteed.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for long-distance transportation of stevia seedlings. Background technique [0002] Stevia is a perennial herbaceous plant of Compositae, native to subtropical South America. The roots, stems and leaves of Stevia rebaudiana contain steviol glycosides. Stevioside has the characteristics of high sweetness (200-300 times that of sucrose), low calorie (only 1 / 300 of sucrose), and can increase blood sugar, lower blood pressure, and promote metabolism. Heart disease, dental caries, etc. have a certain auxiliary effect, so it has increasingly attracted people's attention and attention, and has become the "third sugar source" after sucrose and synthetic sugar. [0003] With the rapid development of the stevia industry, stevia has been gradually introduced and planted across the country. Dongtai City is the largest breeding base of high-quality stevia seedlings i...

AI Technical Summary

Problems solved by technology

Dongtai City is the largest breeding base of high-quality stevia seedlings in the country, and it is also an important place for exporting stevia seedlings. It transports about 2 billion stevia seedlings to all parts of the country every year. However, a large number of rotten plants often occur during the transportation Seedlings, dead seedlings, the most serious survival rate after transplanting is only about 30%, which not only caused great economic losses to the seller, but also led to the failure of the buyer's production plan

In the local area, stevia is mainly asexually propagated by cutting young stems. In most areas, the main planting method is to purchase stevia seedlings for transplanting. The quality of stevia seedlings after a long period of long-distance transportation directly affects the sweet The survival rate and planting area of ​​chrysanthemum seedlings ultimately affect planting benefits
