Hihia Hoʻohana o ka ʻOihana Hydroponics ma Brazil

ʻO kahi hui mea kanu hydroponic ma Brazil e ʻike ana i ka pH a me ke alakaʻi ʻana o ka hopena i loko o ka pamu peristaltic e hōʻoia i ka nui o nā mea kemika e pono ai i ka wā o ka ulu ʻana o nā mea kanu i loko o ka pae kūpono. No nā mea kanu hydroponic, ʻo ka pae pH kūpono ma waena o 5.5-6.5, ʻo ka waiwai pH haʻahaʻa loa e hoʻoheheʻe maikaʻi ʻole i nā ion metala i loko o ka hopena meaʻai, e hoʻopilikia ana i ka omo ʻana o nā meaʻai e nā mea kanu; ʻoiai ke kiʻekiʻe loa ka waiwai pH hiki ke hana i nā mea hoʻopaʻa ulu nui o nā mea kanu i loko o ka hopena meaʻai, e hoʻopilikia ana i ka ulu maʻamau o nā mea kanu. ʻO ka pae kaohi conductivity ma waena o 1.5ms/cm a me 2.5ms/cm, i loko o kēia pae, hiki i ka conductivity ke hōʻike i ka nui o nā ions i loko o ka hopena, e hōʻoia i ka ulu maʻamau o nā mea kanu hydroponic. Pono e hoʻoholo ʻia ka pae kaohi conductivity kikoʻī e like me nā ʻano mea kanu like ʻole, nā pae ulu a me nā kūlana kaiapuni. Ma keʻano laulā, no nā mea kanu me ka wā ulu lōʻihi, e like me ka letus, celery etc., ʻoi aku ka kūpono o ka kaohi ʻana i ka conductivity ma waena o 1.5ms/cm a me 2.0ms/cm; no nā mea kanu me ka wā ulu pōkole, e like me ka kāpeti Kina, ka sipinaha, a pēlā aku, ʻoi aku ka kūpono o ke kāohi ʻana i ka conductivity ma waena o 2.0ms/cm a me 2.5ms/cm.

Ke hoʻohana nei i nā huahana:
