Embodiment 1

[0017] A method for preparing liquid stevia functional fertilizer: the stems and roots of stevia are fully absorbed, and the weight ratio of the stems, roots and water after fully absorbing water is 20:80; the stems of stevia after fully absorbing water The roots are placed in a fermentation tank and fermented at a temperature of 40°C-50°C for 10-30 days, and the fermented liquid obtained is the stevia functional fertilizer.

Embodiment 2

[0019] A method for preparing liquid stevia functional fertilizer: fully absorb water from the stem and root of stevia, and the weight ratio of the stem and root to water after fully absorbing the water is 15:85; the stevia stem after fully absorbing the water The roots are placed in a fermentation tank and fermented at a temperature of 40°C-50°C for 10-30 days, and the fermented liquid obtained is the stevia functional fertilizer.

Embodiment 3

[0021] A method for preparing liquid stevia functional fertilizer. Stevia stems and roots fully absorb water, and the weight ratio of stevia stems, roots and water after fully absorbing water is 40:60; the stevia stems after fully absorbing water The roots are placed in a fermentation tank and fermented at a temperature of 40°C-50°C for 10-30 days, and the fermented liquid obtained is the stevia functional fertilizer.

[0022] The liquid stevia functional fertilizer of the present invention can be used for foliar spraying, and can increase the sugar content of fruits, improve quality, promote early maturity, and promote coloring. If the stevia functional liquid fertilizer is used for root irrigation or flushing, it can promote rooting, increase yield, inhibit root-knot nematodes, and inhibit soil-borne diseases.

Abstract

The invention relates to a method for preparing liquid stevia rebaudiana functional fertilizer, which is characterized by the following steps: stevia rebaudiana stem and root fully adsorb water, and after full water absorption, the weight ratio between the dry stevia rebaudiana stem and root and water is (15-40):(60-85); and the stevia rebaudiana stem and root after full water absorption are placed in a fermenting tank for fermentation for 10 to 30 days under the temperature ranging from 40 DEG C to 50 DEG C, and the obtained fermentation liquid is the liquid stevia rebaudiana functional fertilizer. The fertilizer can effectively restrain the incidence and the spreading of Meloidogyne, as well as the incidence of soil-borne diseases and improve plant quality. By adopting the fertilizer, without adding any chemical residues in soil, insect pests and diseases can be restrained and the soil quality can be improved at the same time through adopting pure organic fertilizer.

Description

Technical field [0001] The invention relates to the field of agricultural production, in particular to a method for preparing crop fertilizer. Background technique [0002] The role of stevia has been generally recognized internationally: the specific functions are as follows: 1) Stevia can provide sufficient organic nutrition for the emergence of seeds, making the seedlings strong and growing well. 2) Stevia can promote the root development of seedlings, which is beneficial to future transplanting management. 3) Stevia chrysanthemum and stem powder can effectively inhibit root knot nematodes. 4) Stevia chrysanthemum and stem powder can inhibit root rot and fusarium wilt. 5) Stevia stems are by-products of stevia production, and currently only discarded as waste, and the cost is low. [0003] The planting area of ​​stevia is also expanding, and the supply exceeds demand. Stevia products are widely used in medicine and food additive industries. At present, the main application ...
