Special slow-controlled-release fertilizer for strawberry and preparation method of the special slow-controlled-release fertilizer

Abstract

The invention discloses special slow-controlled-release fertilizer for strawberry and a preparation method of the special slow-controlled-release fertilizer. The special slow-controlled-release fertilizer is prepared from the following raw materials in parts by weight: 25 to 30 parts of nitrogen fertilizer, 15 to 22 parts of phosphorus fertilizer, 14 to 21 parts of potassium fertilizer, 20 to 25 parts of decomposed organic active fertilizer, 5 to 8 parts of fructus amomi rotundus, 3 to 5 parts of radix aucklandiae, 3 to 5 parts of humic acid, 3 to 6 parts of polymeric amino acid, 2.5 to 5 parts of medium trace elements, 1 to 2 parts of sterilizing agent, and 1 to 3 parts of coating agent. By compounding the humic acid and the polymeric amino acid, the special slow-controlled-release fertilizer has good effect for improving the soil; by matching the nitrogen, phosphorus and potassium as well as medium trace elements, nutrition of crops can be supplemented, and the soil can be activated; the fertilizer can effectively improve the quality of the strawberry, and strawberry is ensured to grow well; and the preparation method provided by the invention is simple and convenient, low in cost, wide in source of raw materials, and capable of being widely produced and used; and the fertilizer is coated by utilizing an advanced coating technology, so that the loss of the fertilizer can be reduced, and the utilization rate of the fertilizer is increased.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a special slow and controlled release fertilizer for strawberries and a preparation method thereof. Background technique [0002] Strawberry (scientific name: Fragaria × ananassa Duch.), perennial herb, 10-40 cm high. Stems lower than leaves or nearly equal, densely spread. Yellow pilose. Leaves three out, leaflets with short stalks, thicker in texture, obovate or diamond-shaped, dark green above, almost glabrous, pale green below, sparsely hairy, denser along the veins; petioles are densely covered with yellow pilose. Cymes, with a short-stalked leaflet under the inflorescence; flowers bisexual; sepals ovate, slightly longer than epicalae; petals white, nearly round or obovate-elliptic. The aggregated fruit is large, and the persistent sepals are erect, close to the fruit; the tip of the achene is ovate and smooth. The flowering period is April-May, and the fr...
