Ungakhetha kanjani i-plastic seedling tray efanelekile?

Lapho ukhetha inombolo efanele yezimbobo kuthreyi yepulasitiki ukuze ukhule izitshalo, udinga ukunaka lezi zinto ezilandelayo:

1. Izinhlobo zezitshalo: Izitshalo ezahlukene zinezidingo ezihlukene zenani lezimbobo ethreyini lezithombo. Isibonelo, amakhabe nama-eggplant afaneleka kuma-disc anezimbobo ezingama-50, kanti ubhontshisi, ama-eggplant, amahlumela aseBrussels, utamatisi wasebusika kanye nentwasahlobo afaneleka kuma-discs angama-72-hole.
2. Usayizi wezithombo: Izitshalo ezindala zidinga indawo eyengeziwe kanye ne-substrate ukusekela ukukhula kwezimpande, ngakho-ke zingase zidinge amathreyi ezithombo anezimbobo ezimbalwa. Ngokuphambene, izitshalo ezineminyaka emincane yezithombo zingasebenzisa amathreyi ezithombo anenani eliphakeme lezimbobo.
3. Isikhathi sezithombo: Izidingo zezithombo zihlukile ebusika, entwasahlobo nasehlobo nasekwindla. Izithombo zasebusika nezasentwasahlobo ngokuvamile zidinga iminyaka ende yezithombo, izithombo ezinkulu, futhi zingavunwa ngokushesha ngangokunokwenzeka ngemva kokutshala; Izithombo zasehlobo nezasekwindla zidinga izithombo ezincane, ezinomfutho wempande ophezulu, okuvumela ukubambezela izithombo ngemva kokutshala.
4. Izindlela zokukhulisa izithombo: Izindlela ezihlukene zokukhulisa izithombo, njengezithombo zethreyi lembobo, izithombo ezintantayo, izithombo ze-tidal, njll., zinezimbobo ezihlukene zokukhetha amathreyi emigodi. Isibonelo, amathreyi e-polystyrene foam angasetshenziselwa izithombo ezintantayo, kuyilapho amathreyi e-polystyrene esetshenziswa kakhulu ekukhuliseni amathreyi emigodi.
5. Ukukhethwa kwe-substrate: I-substrate kufanele ibe nezici zokuthungwa okuxekethile, ukugcinwa kwamanzi okuhle nomanyolo, kanye nezinto eziphilayo ezinothile. Ama-substrates avamile afana nomhlabathi we-peaty kanye ne-vermiculite akhiwe ngesilinganiso se-2: 1, noma i-peat, i-vermiculite ne-perlite akhiwe ngesilinganiso se-3: 1: 1.
6. Impahla yethreyi lezithombo kanye nosayizi: Impahla yethreyi lezithombo ngokuvamile i-polystyrene foam, i-polystyrene, i-polyvinyl chloride ne-polypropylene. Ubukhulu be-disc ye-cavity ejwayelekile ngu-540mm×280mm, futhi inani lemigodi liphakathi kuka-18 no-512. Ukwakheka kwembobo yethreyi yezithombo ngokuyinhloko kuyindilinga futhi iyisikwele, futhi i-substrate equkethwe emgodini oyisikwele ngokuvamile ingaphezu kuka-30% ngaphezu kwembobo eyindilinga, futhi ukusatshalaliswa kwamanzi kufana kakhulu, futhi uhlelo lwezimpande luthuthuke ngokugcwele.
7. Izindleko zomnotho nokusebenza kahle kokukhiqiza: Ngaphansi kwesisekelo sokungathinti izinga lezithombo, kufanele sizame ukukhetha ithreyi lembobo elinezimbobo ezengeziwe ukuze sithuthukise izinga lokuphumayo endaweni ngayinye.
Uma ucabangela lezi zici ezingenhla, ukukhetha ithreyi lezithombo zepulasitiki elinenani elifanele lemigodi kungaqinisekisa ukukhula okunempilo kwezitshalo futhi kuthuthukise ukusebenza kahle kanye nekhwalithi yezithombo.
