Slow release organic compound fertilizer for water arum

Abstract

The invention discloses a slow release organic compound fertilizer for water arum. The slow release organic compound fertilizer is prepared from the following raw materials in parts by weight: 30 to 50 parts of ammonium nitrate, 4 to 12 parts of dipotassium phosphate, 10 to 20 parts of phosphorite powder, 5 to 12 parts of potassium nitrate, 2 to 8 parts of potassium chloride, 1.5 to 2.5 parts of trace elements, 2 to 5 parts of cyclodextrin medical stone compound, 1 to 4 parts of sodium carboxymethyl cellulose, 2 to 6 parts of disproportionated starch, 60 to 70 parts of organic fertilizer, 2 to 6 part of active carbon, 1 to 4 parts of diatomite, 2 to 5 parts of coal ash and 2 to 4 parts of talcum powder. In the slow release organic compound fertilizer for water arum disclosed by the invention, various elements needed by the growth of the water arum are reasonably compounded, so that the slow release organic compound fertilizer has high fertilizer maintenance performance and slow-release performance; after the slow release organic compound fertilizer is applied to a pond for planting the water arum, quick acting components are slowly released to prolong the fertilizer effect, a water body can be purified, and environmental pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to an organic compound fertilizer for slow-release calla taro. Background technique [0002] Calla taro is a perennial aquatic herb with creeping rhizomes, cylindrical, strong, up to 50 cm long, scale leaves lanceolate, acuminate. The upper petiole of the mature stem is cylindrical, and the lower part has a sheath; the sheath is 7-8 cm long; the blade is 6-14 cm long. Inflorescence peduncle 15-30 cm long; spathe green outside, white inside, with pointed 1 cm long, persistent in fruit but not enlarged. Spadix 1.5-3cm long, 1cm thick at flowering stage; infructome subglobose, broadly elliptic, with 5-7mm long stalk. It often grows in patches in shallow waters such as meadows and swamps. Its flowering period is June to July, but during this period, traditional taro planting mostly uses chemical fertilizers, which are not only easy to lose, but also easy to cause root ro...
