Nutritionally balanced stevia rebaudiana compound fertilizer

Abstract

The invention discloses a nutritionally balanced stevia rebaudiana compound fertilizer comprising the raw materials in parts by weight: 8-16 parts of a fermented corncob powder, 6-14 parts of montmorillonite, 8-16 parts of a traditional Chinese medicine residue, 4-10 parts of composted chicken manure, 20-40 parts of a fermented peanut shell powder, 30-50 parts of rice bran meal, 10-20 parts of flax fiber composite clay, 2-4 parts of expanded perlite, 2-4 parts of a sepiolite powder, 4-8 parts of fruit shell activated carbon, 4-8 parts of humate, 0.8-1.6 parts of ferrous sulfate, 0.6-1.6 parts of zinc sulfate, 1.5-2.5 parts of boric acid, 1-1.8 parts of ammonium molybdate, 4-12 parts of a magnesium potassium sulfate fertilizer, 10-20 parts of monoammonium phosphate, 30-40 parts of urea, 16-22 parts of monopotassium phosphate, 8-16 parts of calcium triple superphosphate, 2-4 parts of wood vinegar, and 3-9 parts of carboxymethyl cellulose. The compound fertilizer has the advantage of reasonable proportion of nutrient elements, increases the utilization rate of the fertilizer and reduces the environmental pollution caused by the loss of the fertilizer.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a stevia compound fertilizer with balanced nutrition. Background technique [0002] Stevia is a plant of Compositae, native to the subtropical region of South America. It was successfully introduced in China in 1977 and has been cultivated in more than 20 provinces and cities. Stevia is a perennial herb with a plant height of 1-1.3 meters. Roots are slightly hypertrophic, 50-60, up to 25 cm long. Stevia is a short-day plant with strong sensitivity to light, and the critical day length is 12 hours, so it is cultivated and flowered earlier in low latitude areas. Stevia is not strict on the soil, but it grows well in loose and fertile land with more humus. The soil should be neutral in pH, less than 5.5 or greater than 7.9 are not suitable. Long-term maintenance of water and fertilizer nutrients without loss. With the rapid development of the stevia industry, the planting a...

Problems solved by technology

With the rapid development of the stevia industry, the planting area in Northeast my country is also expanding. At this stage, conventional fertilization methods have the problem of unbalanced nutrient distribution and low nutrient utilization rate, which not only wastes nutrients, but also easily damages rivers and rivers due to runoff. groundwater pollution
