Ukulinywa kwezithole kusoloko kuyeyona nto iphambili kulawulo lokulinywa kwemifuno. Imifuno ineziphene ezininzi ekulinyweni kwezithole, ezinje ngemilinganiselo ephantsi yezithole ezomeleleyo kunye nezithole ezifanayo, kwaye iitreyi zembewu zinokulungisa ezi ntsilelo. Masifunde ngeendlela zobugcisa zokutyala imifuno kwiitreyi zezithole.
1. Ukukhethwa kweetreyi zembewu
Ubungakanani betreyi yembewu yi-54 * 28cm, kwaye iinkcukacha ezisetyenziswa ngokuqhelekileyo yimingxuma engama-32, imingxuma engama-72, imingxuma eyi-105, imingxuma eyi-128, imingxuma engama-288, njl. Kwizithole ezinkulu, khetha iitreyi zembewu ezinemingxuma embalwa, kwaye kwizithole ezincinci, khetha iitreyi zembewu ezinemingxuma emininzi. Umzekelo: kwizithole ze-tomato ezinama-6-7 amaqabunga okwenyaniso, khetha imingxuma engama-72, kunye neetamatato ezinamacembe angama-4-5 okwenyaniso, khetha imingxuma eyi-105 okanye eyi-128.
2. Ukubulala iintsholongwane kwitreyi yembewu
Ngaphandle kweetreyi ezintsha ezisetyenzisiweyo okokuqala, iitreyi ezindala kufuneka zibulawe iintsholongwane phambi kokulinywa kwezithole ukunqanda ukusasazeka kwezifo ngetreyi zenursery. Kukho iindlela ezininzi zokubulala iintsholongwane. Enye kukumanzisa itreyi yezithole ngesisombululo se-0.1% ukuya kwi-0.5% ye-potassium permanganate ngaphezulu kweeyure ezi-4; okwesibini kukutshiza i-tray yesithombo nge-1% ukuya kwi-2% yesisombululo se-formalin, kwaye emva koko uyigqume ngefilimu yeplastiki kwaye uyitshise iiyure ezingama-24; eyesithathu kukuyifunxa nge-10% yomgubo owenziwe ngebleach kangangemizuzu eyi-10 ukuya kwengama-20, emva koko uhlambe itreyi yezithole ngamanzi acocekileyo ukuze uyisebenzise.
3. Ixesha lokuhlwayela
Ukumiselwa kwexesha lokuhlwayela ngokuqhelekileyo kusekelwe kwimiba emithathu yenjongo yokulima (ukuvuthwa kwangethuba okanye ukwindla okwandisiweyo), indlela yokulima (ukulima kwindawo okanye ukulima umhlaba) kunye neemfuno zobushushu bokukhula kwemifuno. Ngokuqhelekileyo, ukuhlwayela kwenziwa malunga nenyanga enye ngaphambi kokutshintshwa kwezithole zemifuno.
4. Ukulungiswa komhlaba wezondlo
Umhlaba wezondlo ungathengwa njenge-seedling substrate esele yenziwe, okanye unokulungiswa ngokwakho ngokwendlela yepeat: vermiculite: perlite = 2:1:1. Xuba i-200g ye-50% ye-carbendazim yomgubo omanzi kwi-cubic meter nganye yomhlaba wesondlo sokubulala iintsholongwane kunye nokuvalwa. Ukudibanisa i-2.5kg yesichumiso se-phosphorus ephezulu kwi-cubic meter nganye yomhlaba wesondlo kuya kunceda ukuhluma kunye nokomeleza izithole.
5. Ukuhlwayela
Yongeza amanzi kumhlaba wezondlo kwaye ushukumise de ufume, uze ubeke i-substrate emanzi kwitreyi kwaye uyigudise ngentonga ende yomthi. I-substrate efakelweyo kufuneka icinezelwe ukuze kube lula ukubeka imbewu. Ubunzulu boxinzelelo lomngxuma yi-0.5-1cm. Faka imbewu egqunyiweyo emingxunyeni ngesandla, imbewu enye ngomngxuma. Gquma ngomhlaba owomileyo wezondlo, emva koko sebenzisa i-scraper ukukrazula ukusuka kwelinye icala le-tray yomngxuma ukuya kwelinye icala, susa umhlaba ogqithisiweyo wezondlo, kwaye wenze umgangatho kunye netreyi yomngxuma. Emva kokuhlwayela, itreyi yomngxuma kufuneka inkcenkceshelwe kwangethuba. Ukuhlola okubonakalayo kukubona amathontsi amanzi emazantsi etreyi yomngxuma.
6. Ulawulo emva kokuhlwayela
Imbewu ifuna ubushushu obuphezulu kunye nokufuma ngexesha lokuntshula. Ubushushu bugcinwa ku 32 ~ 35 ℃, kunye ne 18 ~ 20 ℃ ebusuku. Akukho kunkcenkceshelwa phambi kokuntshula. Emva kokuntshula kumagqabi okwenyaniso, ukunkcenkceshela kufuneka kwandiswe kwangexesha ngokuhambelana nokufuma komhlaba webhedi yembewu, ukutshintshwa phakathi komileyo nokumanzi, kwaye ukunkcenkceshela nganye kufuneka kunkcenkceshelwe kakuhle. Ukuba iqondo lobushushu kwi-greenhouse lidlula i-35℃, kufuneka kuqhutyelwe kungena umoya ukupholisa i-greenhouse, kwaye ifilimu yomhlaba kufuneka isuswe kwangethuba ukunqanda ukutshiswa kwezithole.
Iitreyi zezithole zemifuno zinokuvelisa ngokufanelekileyo izithole ezomeleleyo, ziphucule umgangatho wezithole zemifuno, kwaye zandise inzuzo yezoqoqosho yokutyala imifuno. I-Xi'an Yubo ibonelela ngoluhlu olupheleleyo lweetreyi zembewu ukunika ukhetho oluninzi malunga nokutyala kwakho imifuno
