Description

technical field [0001] The invention belongs to the technical field of flower fertilizers, in particular to special fertilizers used in production cultivation and indoor maintenance of ornamental pineapple flowers. Background technique [0002] Flowers are high-end consumer goods with high quality requirements, but due to improper selection of fertilizers and other reasons in production, it often leads to the lack or excess of certain nutritional elements, resulting in poor growth, poor leaf color, deformity, etc., seriously affecting product quality . Ornamental pineapple is the general term for many pineapple varieties such as Yingge (sword), Qingtian (star) and pink pineapple that are used for viewing in Bromeliaceae. Among them, Yingge and Qingtian have the highest ornamental value and the cultivation volume The biggest, the cultivation difficulty is also big, especially high to fertilizer requirement, so the present invention is also based on solving the special-purpos...

Problems solved by technology

Ornamental pineapples mainly absorb fertilizer from the leaf cup, followed by the leaves and roots, so fertilization is mainly applied in the leaf cup; the fertilizer must be fully water-soluble, otherwise the residual salt will gradually spread on the surrounding walls of the leaf cup. Accumulation (not like the residues in the soil that are easily leached by irrigation water), which will affect the absorption of fertilizer by the scales; the concentration of fertilization should not be too high; especially the ratio of various fertilizer elements, including trace elements Cu, Zn, B, etc. Reasonable, otherwise it will cause element accumulation and poisoning. Therefore, the fertilizers that were routinely applied to various crops in the past are not suitable for the cultivation of ornamental pineapples.

At present, in the domestic fertilizer market, there is no domestically produced special fertilizer for ornamental pineapples. Only the "Huaduoduo No. 9 fertilizer" (special fertilizer for pineapple) produced in the United States is available, but on the one hand, it is expensive, and on the other hand, it is labeled N.P 2 o 5 、K 2 The ratio of O is 20:10:20. After a long-term trial, the producer has found that its N, P 2 o 5 High content and K 2 The low O content leads to tender pineapple plants, low success rate of flower promotion, poor flower organ development, and poor flower color. Therefore, when applied in production, it is generally necessary to apply other potassium fertilizers to adjust and overcome its nitrogen content. The defect of more potassium and less, which brings a lot of inconvenience to the user

In addition, the "Huaduoduo No. 9 Fertilizer" in the United States only lists the N and P of this special fertilizer. 2 o 5 、K 2 The ratio of O is 20:10:20, and there is no specific raw material name and content of each macroelement elemental fertilizer when preparing it, nor is the specific raw material name and content of each trace element listed; at the same time, "Hua Duoduo No. It can be found in the formula that it is only suitable for the vegetative growth period, but not for the reproductive growth period. Therefore, users are required to stop applying it for 2 months when the ornamental pineapple enters the flowering period. quality is of course a disadvantage
