Problems solved by technology

[0003] Due to the small size of Stevia rebaudiana seeds, the dry grain weight is only 0.25-0.4 grams, and there are few stored nutrients. During the early spring seedling cultivation of Stevia rebaudiana, due to the large temperature changes, Stevia rebaudiana seeds are extremely vulnerable to low temperature, chilling damage, high temperature, etc. during the germination process. Affected by adversity, it is easy to lose growth ability during germination

Abstract

The invention belongs to the technical field of agricultural planting, and particularly relates to a stevia rebaudiana seed cold-resistant agent, comprising the following components in parts by weight: 4-12 parts of paclobutrazol, 8-20 parts of chitosan, 10-16 parts of humic acid, 4-6 parts of nitric acid, 10-20 parts of rapeseed oil, 6-10 parts of a compound emulsifier, 6-10 parts of a compound antifreeze and 600-800 parts of distilled water. The stevia rebaudiana seed cold-resistant agent provided by the invention has the following beneficial effects: after seed soaking treatment with the paclobutrazol, chitosan, humic acid, nitric acid, rapeseed oil, compound emulsifier and compound antifreeze, the resistance and growing ability of stevia rebaudiana seeds under a cold environment are obviously improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a cold-resistant agent for stevia rebaudiana seeds. Background technique [0002] Stevia is an herb of Compositae, native to Paraguay. It was successfully introduced and cultivated in my country in the early 1980s. The sweetness of steviol glycosides in its leaves is more than 300 times that of sucrose. It is known as the most valuable and promising new healthy sugar. source. [0003] Due to the small size of Stevia rebaudiana seeds, the dry grain weight is only 0.25-0.4 grams, and there are few stored nutrients. During the stevia seedling cultivation process in early spring, due to the large temperature changes, Stevia rebaudiana seeds are extremely vulnerable to low temperature, chilling damage, high temperature, etc. during the germination process. Under the influence of adversity, it is easy to lose the growth ability during the germination process. ...
