Background technology
Hybrid cymbidium is the representative species of cattleya, be people to from originating in the grow nonparasitically upon another plant general designation of the kind that cultivates kind of the filial generation of the geographic Cymbidium Da Hua of tropical and subtropical zone type, have advantages such as plant is strong, Hua Dahua is many, pattern is gorgeous, and the florescence is lasting, the laudatory title of " king of cattleya " is arranged.Both suitable potted plant decoration, but also cut-flower is viewed and admired, and far sees rough, the bold and unconstrained magnificence of colored appearance, closely see that spire is whirling, slim and graceful existing cattleya gorgeous and luxurious, have the colourful of state orchid and grace again, well received at home.
The hybrid cymbidium cultivation time is longer, is generally 3-4, according to growth period, season and upgrowth situation, need the quantity and the concentration of change fertilizer, and solid fertilizer is difficult for regulating concentration and consumption, has many deficiencies in the cultivation of hybrid cymbidium.
Summary of the invention
The objective of the invention is to provides a kind of nutritive medium that is applicable to the hybrid cymbidium cultivation at above-mentioned deficiency.
Hybrid cymbidium nutritive medium of the present invention contains for every liter: nitrogen N 100~300mg, phosphorus P31~124mg, potassium K 117~274mg, calcium Ca 60~80mg, magnesium Mg 24~26mg, iron Fe 2.200~2.873mg, boron 0.409~0.509mg, manganese Mn 0.412~0.523mg, zinc Zn 0.042~0.052mg, copper Cu 0.010~0.019mg, molybdenum Mo 0.010~0.013mg.
Preferably, every liter of nutritive medium contains: N 200mg, phosphorus P 62mg, potassium K 274mg, calcium Ca 80mg, magnesium Mg 24mg, iron 2.873mg, boron 0.509mg, manganese 0.523mg, zinc 0.052mg, copper 0.019mg, molybdenum 0.013mg.
And, above-mentioned nutritive medium can be diluted or concentrate, obtain the nutritive medium of different concns.
Among the present invention, described N can use urea, ammonium nitrate or other nitrogenous fertilizer preparations; Described iron can be used FeSO
4And Na
2-EDTA preparation, also available Na
2Fe-EDTA, preparations such as Fe-DTPA.
Hybrid cymbidium nutritive medium of the present invention is used for hybrid cymbidium and can makes the hybrid cymbidium speed of growth faster than traditional fertilizer, and it is more healthy and stronger to grow, and can reduce disease and pest.
