Problems solved by technology

According to estimates, the utilization rate of nitrogen fertilizer in my country is low, about 30%-35%, and most of it enters the water body and the atmosphere through volatilization, leaching, runoff, etc., which not only wastes energy, but also causes nitrate in soil and water. Accumulation of harmful substances such as polluting the environment
In addition, the existing nitrogen fertilizers have relatively simple nutrition. Although they can promote plant growth, they cannot meet the requirements for zinc deficiency and stress resistance of crops, and long-term application will easily lead to soil compaction and deterioration of the soil environment.

Abstract

The invention provides a method for preparing a flos hibisci slow-release fertilizer; the method comprises the steps: firstly, drying and crushing straw, and carrying out high temperature carbonization of the crushed straw to obtain a carbonized material; then drying and sieving fishpond sludge, to obtain a sludge powder; then mixing the carbonized material, the sludge powder, potassium phosphate, sodium nitrate, potassium bicarbonate, a hydroxypropyl methylcellulose aqueous solution and absolute ethyl alcohol and granulating, and finally drying the obtained granular fertilizer, to obtain the slow-release fertilizer. The slow-release fertilizer not only can increase the flowering amount in a flowering period, prolongs the flowering period, also can reduce the incidence rate of flower plants and has good use effect.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a preparation method of hibiscus flower slow-release fertilizers. Background technique [0002] Hibiscus flower, is a common garden shrub flower species, Malvaceae Hibiscus (Hibiscus syriacus L), alias white hibiscus flower, palm tree flower, big bowl flower, fence flower, Qingming fence, rice flower, chicken flower, pig flower Oil flowers bloom in the morning and fall in the evening. The hibiscus flower is bright in color and is an excellent plant for free-style flower hedges. It is suitable for planting on both sides of roads, parks, courtyards, etc., and can be planted alone, in rows or in patches. In addition, hibiscus flowers can be used as medicine and edible. [0003] At present, nitrogen fertilizer is the most widely used fertilizer, and nitrogen fertilizer products mainly include urea, ammonium chloride, ammonium sulfate, ammonium bicarbonate, ammonium ...
