AI Technical Summary

Problems solved by technology

The climate is dry in spring, and most of the fibrous roots of bare-root seedlings will dry up and lose water after being placed under natural conditions for a few hours. The risk of dead seedlings is greatly increased, and the survival rate of transplanting is generally less than 40%.
However, most of the researchers' studies on how to improve the survival rate of stevia transplanting focus on soil texture, seedling quality, basal fertilizer application, climatic conditions, etc., and there are very few discussions on transplanting techniques.

Abstract

The invention discloses a coating agent for improving the transplanting survival rate of stevia rebaudiana. The coating agent for improving the transplanting survival rate of stevia rebaudiana is prepared from the following materials including, by weight part, 1500-2000 parts of attapulgite powder, 1500-2000 parts of clay powder, 1-2 parts of bactericides, 5-7 parts of monopotassium phosphate, 25-35 parts of white granulated sugar, 25-35 parts of rice vinegar, 1500-2000 parts of willow twigs and 3000-4000 parts of water. The invention also discloses a preparation method of the coating agent for improving the transplanting survival rate of stevia rebaudiana and a specific application method of the coating agent during stevia rebaudiana transplanting. When applied to transplanting stevia rebaudiana, the coating agent and the application method of the coating agent can significantly improve the transplanting survival rate and the yield of stevia rebaudiana.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation seedling treatment, and more specifically relates to a coating agent for improving the transplanting survival rate of stevia rebaudiana and its preparation method and application. Background technique [0002] Stevia is native to subtropical regions of South America and is a perennial herb of the genus Stevia in the family Asteraceae. Stevioside extracted from stevia rebaudiana is a natural, high-sweet, low-calorie, new green health-care sweetener. It is an ideal substitute for sucrose and beet sugar and is widely used in food, beverage and other industries. In addition, steviol glycosides have outstanding effects in anti-cancer, reducing blood sugar concentration in type 2 diabetes and controlling high blood pressure. Therefore, stevia has extremely considerable economic benefits and social value. [0003] With the increasing demand of stevia, its planting area is also expandin...
