Nkhani - Momwe Mungakulire Letesi mu Wowonjezera Wowonjezera kutentha M'nyengo yozizira Ndondomeko ya Tsatanetsatane

Kodi mumalakalaka letesi watsopano m'miyezi yozizira? Osadandaula! Kukula letesi mu wowonjezera kutentha kungakhale kopindulitsa komanso kokoma. Tsatirani malangizowa kuti mukhale katswiri wolima letesi m'nyengo yozizira.

Kukonzekera Dothi Lobzala Wowonjezera Wowonjezera Mzinja

Nthaka ndiye maziko a kukula kwa letesi wathanzi. Sankhani dothi lotayirira, lachonde lamchenga kapena dongo lotayirira. Dothi lamtundu uwu limakhala ndi mpweya wabwino, zomwe zimapangitsa kuti mizu ya letesi ipume momasuka komanso kupewa kutsika kwamadzi. Onjezani ma kilogalamu 3,000-5,000 a feteleza wovunda bwino ndi ma kilogalamu 30-40 a fetereza wapawiri pa ekala. Sakanizani feteleza bwino m'nthaka polima mpaka 30 centimita. Izi zimatsimikizira kuti letesi amapeza zakudya zonse zomwe amafunikira kuyambira pachiyambi. Kuti nthaka yanu ikhale yathanzi komanso yopanda tizilombo, sakanizani ndi 50% thiophanate-methyl ndi mancozeb. Gawo ili lipanga malo oyera komanso athanzi kuti letesi yanu ikule.

Kuwonjezera Insulation Yowonjezera ku Greenhouse M'nyengo yozizira

Kutentha kwa wowonjezera kutentha ndikofunikira m'nyengo yozizira. Kuonjezera magawo owonjezera a insulation kungapangitse kusiyana kwakukulu. Kuonjezera makulidwe a chivundikiro cha wowonjezera kutentha kwanu mpaka 5 centimita kumatha kukweza kutentha mkati ndi 3-5 digiri Celsius. Zili ngati kupatsa wowonjezera kutentha wanu bulangeti wandiweyani, wofewa kuti musamazizira. Mukhozanso kuyika makatani otsekemera amitundu iwiri m'mbali ndi pamwamba pa wowonjezera kutentha. Izi zitha kuwonjezera kutentha ndi madigiri 5 Celsius. Kupachika filimu yowunikira kumbuyo kwa khoma ndikusuntha kwina kwanzeru. Imawonetsa kuwala kubwerera mu wowonjezera kutentha, kuonjezera kuwala ndi kutentha. Kwa masiku ozizira kwambiri, ganizirani kugwiritsa ntchito zitsulo zotenthetsera, zotenthetsera kutentha, kapena ng'anjo zotentha zamoto. Zipangizozi zimatha kusintha kutentha, kuonetsetsa kuti wowonjezera kutentha wanu amakhala wotentha komanso wangwiro pakukula kwa letesi.

pH ndi EC Level Monitoring ya Hydroponic Lettuce mu Zima

Ngati mukukula letesi pa hydroponically, kuyang'anitsitsa pH ndi EC ya yankho lanu lazakudya ndikofunikira. Letesi amakonda mulingo wa pH pakati pa 5.8 ndi 6.6, wokhala ndi 6.0 mpaka 6.3. Ngati pH ili pamwamba kwambiri, onjezerani ferrous sulfate kapena monopotassium phosphate. Ngati ndi otsika kwambiri, madzi a mandimu amatha kuchita chinyengo. Yang'anani pH mlungu uliwonse ndi mizere yoyesera kapena pH mita ndikusintha ngati pakufunika. Mulingo wa EC, womwe umayesa kuchuluka kwa michere, uyenera kukhala pakati pa 0.683 ndi 1.940. Kwa letesi wamng'ono, khalani ndi mlingo wa EC wa 0.8 mpaka 1.0. Zomera zikamakula, mutha kuziwonjezera mpaka 1.5 mpaka 1.8. Sinthani EC powonjezera mchere wokhazikika kapena kuchepetsa yankho lomwe lilipo. Izi zimawonetsetsa kuti letesi wanu amapeza zakudya zoyenera pagawo lililonse la kukula.

Kuzindikira ndi Kuchiza Tizilombo toyambitsa matenda mu Greenhouse Letesi M'nyengo yozizira

Kuchuluka kwa chinyezi m'nyumba zobiriwira kungapangitse letesi kuti atengeke ku matenda. Yang'anirani zinthu zomwe zimafala monga downy mildew, zomwe zimayambitsa nkhungu zoyera pansi pa masamba ndi chikasu; zowola zofewa, zomwe zimatsogolera kumadzi amadzimadzi, onunkhira; ndi imvi nkhungu, amene amapanga imvi nkhungu pa masamba ndi maluwa. Pofuna kupewa mavutowa, sungani kutentha kwa wowonjezera kutentha pakati pa 15-20 digiri Celsius ndi chinyezi pa 60% -70%. Ngati muwona zizindikiro za matenda, samalirani zomera ndi 75% chlorothalonil wosungunuka nthawi 600-800 kapena 58% metalaxyl-manganese zinc. Uza mbewuzo kwa masiku 7-10 aliwonse kwa 2-3 ntchito kuti tizilombo toyambitsa matenda tisasokonezeke ndi letesi wanu wathanzi.

Kulima letesi mu wowonjezera kutentha m'nyengo yozizira ndi njira yabwino yosangalalira ndi zokolola zatsopano komanso kusangalala ndi dimba. Tsatirani izi, ndipo mukolola letesi watsopano ngakhale m'miyezi yozizira kwambiri.
