Special fertilizer for potted cottonrose hibiscus and application method

Abstract

The invention provides a special fertilizer for potted cottonrose hibiscus, which comprises the following components in percentage by mass: 31.2-99.7 wt% of an organic fertilizer, 0.1 to 66.1 wt% of apotassium-containing mineral and 0.2-16.5 wt% of a chemical fertilizer mixture; wherein the chemical fertilizer mixture comprises a nitrogen fertilizer, a potassium fertilizer, a phosphate fertilizerand a controlled-release nitrogen fertilizer. The invention also provides an application method of the special fertilizer. Organic matters, the potassium-containing mineral and soil are fully mixed to prepare mixed soil, the mixed soil provides sufficient nutrients for cottonrose hibiscus, and then the chemical fertilizer mixture is applied to the positions 3-5 cm away from the root of the cottonrose hibiscus and 5-10 cm away from the ground surface, so that long-term nutrition is provided for the long-term fertilizer efficiency of the cottonrose hibiscus by adopting the special fertilizer and the application method, soil hardening can be effectively reduced, nutrient requirements of growth of the cottonrose hibiscus can be met, and the flowering phase quality of the cottonrose hibiscus can be improved.

Description

technical field [0001] The invention relates to the technical field of potted plants, in particular to a special fertilizer for potted Hibiscus hibiscus and an application method.

Problems solved by technology

[0003] As a bonsai, the nutritional requirements are relatively high, and fertilization is more difficult. In order to ensure the normal growth and development of the potted hibiscus, especially during the growth process, it is necessary to supplement a large amount of mineral nutrients in a timely and appropriate amount. Such an operation will Increase a series of labor costs and material costs. The existing supplementary macronutrient fertilizers use relatively traditional instant nitrogen fertilizers and potassium fertilizers, which are highly water-soluble. When too much is applied at one time, a considerable part is easy to be lost with water, polluting the environment, and also A waste of resources, in addition, inputting too much instant fertilizer will also cause soil compaction in the potted plant, which is seriously unfavorable to the growth of Hibiscus hibiscus; use organic fertilizer for fertilization, although the organic fertilizer can meet the requirements of certain medium and trace elements, but the macronutrients The content is low, and its strength and release rate cannot meet the growth requirements of Hibiscus hibiscus
