Abstract

The invention discloses a fertilizer capable of controlling the damping-off of stevia rebaudiana, and relates to the technical field of stevia rebaudiana plantation. The fertilizer comprises the following components in parts by weight: 150 to 200 parts of plant ash, 100 to 120 parts of urea, 100 to 120 parts of cotton seed shell and rapeseed shell, 70 to 90 parts of straw, 70 to 90 parts of tea dregs, 60 to 70 parts of cowpea vine, 20 to 40 parts of fish bone, 30 to 40 parts of sheep manure, 70 to 90 parts of nutritional liquid, 50 to 60 parts of Chinese herbal additive, and 50 to 60 parts of bactericide. The fertilizer can supply elements required for the growth of stevia rebaudiana and can also prevent and treat damping-off of stevia rebaudiana.

Description

technical field [0001] The invention relates to the technical field of stevia planting, in particular to a fertilizer capable of preventing and treating stevia blight. Background technique [0002] Blight is the main disease of Stevia rebaudiana seedling stage. It is a disease caused by a variety of fungi in the rhizome, also known as stem rot, damping-off, blackfoot and so on. The harmful fungi are mainly Rhizoctonia and Fusarium. Seed seedlings showed damping-off at the seedling stage. The disease occurs about 30 days after sowing, when the stevia seedlings grow to a height of about 1 cm from the ground. In the early stage, light yellow water-soaked spots appeared at the base of the roots, and the spots expanded rapidly. After surrounding the roots, the seedlings fell from the sick parts, and the upper branches and leaves were still green. After 2 to 3 days, the lesions will become shriveled and thinner, and the upper part will become wilted and die. If this disease is...
