Abstract

The invention specifically relates to a fertilizer for Stevia rebaudiana, belonging to the technical field of agricultural plantation. The fertilizer comprises, by weight, 200 to 300 parts of urea, 10 to 20 parts of zinc sulfate, 20 to 30 parts of potassium phosphate, 10 to 20 parts of apple pomace, 5 to 15 parts of dried chicken manure, 30 to 40 parts of vinasse, 10 to 20 parts of cassava residues, 5 to 15 parts of plant ash, 10 to 20 parts of shell powder and 5 to 15 parts of silkworm excrement. According to the invention, nutrient elements are reasonably proportioned; after application of the fertilizer, nutritional demands of Stevia rebaudiana are met, the utilization rate of the fertilizer is increased, environmental pollution caused by loss of the fertilizer is alleviated, and sustainable development of an agricultural ecological system is benefited; and the fertilizer has high economic benefits and promotion value and exerts long-acting and stable effect.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a fertilizer for stevia. 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] However, the conventional fertilization method at this stage has the problem of unbalanced nutrient distribution, which not only causes waste of nitrogen and phosphorus fertilizers, but also easily pollutes rivers and groundwater due to runoff. must do. The invention rationally matches the ratio of nutrient elements, and after application, it not only solves the nutritional demand problem of stevia rebaudiana, but also improves the fertilizer utilization rate, reduces environmental pollution caused ...
