Abstract

The invention relates to the fertilizer technical field, and in particular relates to a stevia organic compound fertilizer comprising the following raw materials by weight: 50-60 parts of stevia root stem and rod, 5-7 parts of clay, 10-20 parts of urea, 10-20 parts of ammonium hydrogen phosphate, 6-8 parts of potassium sulfate, 3-5 parts of potassium dihydrogen phosphate, 8-10 parts of polymer water absorbent resin and 20-30 parts of a biological organic fertilizer. The stevia organic compound fertilizer is green, pollution-free, non-toxic, harmless, free of any side effects, anti-drought, water holding, fertilizer maintaining, seedling maintaining, and capable of improving soil, prevents soil hardening, adjusts soil pH value to neutral, do not pollutes the environment, can effectively inhibit the occurrence and spread of root knot nematode, suppresses soil borne diseases, and can improve the quality of crops.

Description

[0001] technical field [0002] The invention relates to the technical field of fertilizers, in particular to a stevia organic compound fertilizer. Background technique [0003] 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. The stem is erect, the base is slightly lignified, and the upper part is soft and densely covered with short hairs. The leaves are opposite or the upper parts of the stems are alternate, draped in shape, with shallow serrations on the edges, short hairs on both sides, and three veins. Inflorescence small, involucre tube-shaped, involucre 5-6 layers, sides equal in length; receptacle flat, bald; corolla base light purple or white, upper part white. Achene linear, slightly flattened, brow...
