Description
Technical field
The invention belongs to the flower fertilizer technical field, especially belong to ornamental pine apple class flowers applied dedicated fertilizer in producing cultivation and indoor maintenance.
Background technology
Flowers are luxury goodss, and are higher to quality requirements, and produce to go up owing to fertilizer is selected reasons such as improper for use, often cause the shortage or the surplus of some nutritive element, thereby cause phenomenons such as poor growth, leaf look not good, deformity, have a strong impact on quality product.The general name that ornamental pine apple is the many warbler brother classes (sword class) that are used to view and admire of Bromelia family, hold up pineapple kinds such as a day class (star class) and powder pineapple class, wherein warbler brother class and guzmania ananas sativus ornamental value are the highest, cultivation amount maximum, the cultivation difficulty is also big, high especially to the fertilizer requirement, so the present invention is also to solve warbler brother class and to hold up day dedicated fertilizer of class ornamental pine apple.These class flowers originate in tropical rain forest, grow nonparasitically upon another plant mostly and stick in tree, are absorbed by the palea in the leaf cup and grow by the dead twigs and withered leaves that drops on Ye Beizhong and the septic nutrient of insect corpse, under such habitat, have formed its specific demand to fertilizer for a long time.Ornamental pine apple absorbs the organ of fertilizer based on the leaf cup, and leaf and root system are inferior, so fertilising is to execute in the leaf cup; Fertilizer then must be full water-soluble, otherwise its remaining salt branch progressively accumulation on leaf cup perisporium (can not as in the soil residual easily by the irrigation water leaching loss), and then influence the absorption of palea to fertilizer; Fertilising concentration can not be too high; Especially each fertilizer element comprises that the proportioning of micro-Cu, Zn, B etc. is wanted rationally, otherwise can cause element accumulation and poison, and therefore, the fertilizer that all kinds of in the past crop routines are used all should not be used in the cultivation of ornamental pine apple.On the present domestic fertilizer market, also do not have home-made to be used for the dedicated fertilizer of ornamental pine apple, have only the U.S. to produce " flower is No. 9 fertilizer the more " (pineapple is special-purpose fertile) supply is arranged, but it costs an arm and a leg on the one hand, on the other hand its N that marks, P
2O
5, K
2The O proportioning is 20: 10: 20, and the producer finds its N, P after long-term trying out
2O
5Higher and the K of content
2O content is on the low side, causes the pineapple plant to look tenderer, and the flower forcing success ratio is not high, the floral organ tissue development is unhealthy and strong, and pattern is relatively poor, goes up when using so produce, generally also need join and execute other potash fertilizer, overcome the few defective of the many potassium of its nitrogen, bring inconvenience to user like this to adjust.In addition, only listed on U.S.'s " flower the more No. 9 fertilizer " detail file should special use fertilizer N, P
2O
5, K
2The O ratio is 20: 10: 20, and does not have the concrete material name and the content of each macroelement simple substance fertilizer when preparing, also the concrete material name and the content of unlisted each trace element; Simultaneously, " flower is No. 9 fertilizer the more " can be found from its prescription, be only applicable to vegetative growth phase, and also inapplicable reproductive stage is used, thus require the user in using, when ornamental pine apple enters flower forcing during the phase, must stop to use 2 months, that yes is disadvantageous to the floral organ quality that improves ornamental pine apple for this.
Summary of the invention
The present invention seeks at weak point with the upper inlet dedicated fertilizer for ornamental pineapple, propose a kind ofly can effectively promote nourishing and growing and promoting its reproductive growth of ornamental pine apple, full water-soluble, no salinity accumulation in pineapple plant water tumbler and potting media, each element reasonable ratio, plant safety, moderate cost, dedicated fertilizer for ornamental pineapple easy to use.
