Problems solved by technology

[0003] Stevia mostly uses asexual cutting seedlings to propagate seedlings. Stevia cutting seedlings are an effective way to maintain the purity of stevia varieties, prevent degradation and expand seedling breeding. However, in the stevia seedling stage, stevia seedlings are relatively fragile and susceptible to The threat of pests and diseases leads to the death of stevia seedlings due to rotten roots and diseases, which reduces the survival rate of stevia seedlings

Abstract

The invention provides a stevia rebaudiana cutting nursery substrate. The nursery substrate is composed of an upper layer substrate and a lower layer substrate. The lower layer substrate is prepared from, by weight, 50-60 parts of silver sand, 20-30 parts of yellow soil, 10-12 parts of composted farmyard manure, 6-8 parts of rice hulls, 6-8 parts of kieselguhr, 2-4 parts of chinaberry, 2-4 parts of bark of ash and 1-3 parts of fructus cnidii. The upper layer substrate is prepared from, by weight, 40-50 parts of silver sand, 25-35 parts of yellow soil, 15-20 parts of wormcast and 5-7 parts of kaolin. The thickness of the lower layer substrate is 10-15 cm, and the thickness of the upper layer substrate is 3-4 cm. The stevia rebaudiana cutting nursery substrate contains abundant nutrients, layering treatment is adopted, and the requirement for growth of stevia rebaudiana seedlings is met; meanwhile, Chinese herbal medicinal ingredients are added additionally, growth of bacteria at the roots of stevia rebaudiana seedlings is prevented, and rotten seedling roots are effectively avoided, and the seedling survival rate is increased.

Description

technical field [0001] The invention relates to the technical field of stevia planting, in particular to a stevia cutting seedling raising substrate. Background technique [0002] Stevia is a perennial herb of the genus Stevia in the Asteraceae family. The whole Stevia plant contains sugar, and the sweetness of the leaves is the highest, containing about 14% glycosides. The glycosides of the branches are equivalent to half of the leaves. Stevia leaves can be used as sugar after drying and crushing, or through ethanol precipitation Obtain stevioside, the sweetness is equivalent to 250-300 times that of white sugar, and the calories are only 1 / 300 of white sugar. Not only that, stevioside has no toxic side effects, no carcinogens, safe to eat, regular consumption can prevent high blood pressure , diabetes, obesity, heart disease, dental caries and other diseases, it is an ideal sweetener to replace sucrose. At present, it has been widely used in food, beverage, medicine, dai...
