Ngati mphamvu ya kutentha ndi msinkhu wa mlengalenga imasokonezeka mu wowonjezera kutentha, ndiye kuti nkhaka zowonongeka mosamala zimayambira. Poyambirira kuti adziwe ndikuzindikira matendawa, ndibwino kuti zokolola zikhale zathanzi kwambiri. Kotero tiyeni tiyang'ane pa nkhaka mu wowonjezera kutentha.
Ambiri matenda a nkhaka mu greenhouses
Anthracnose ndi matenda a fungal a nkhaka, omwe amadza chifukwa cha mkulu chinyezi mu wowonjezera kutentha. Matendawa amayamba ndi maonekedwe ofiira ofiira pa masamba ndi masamba, ndiyeno pa zipatso za zilonda zam'mimba ndi pinki. Zipatso zoyipa ziyenera kuwonongedwa mwamsanga, chifukwa sizidzakula kukula.
Zomwe mungachite: Ngati mutapeza zizindikiro zoyamba za matendawa, perekani kamodzi pa sabata ndi yankho la Bordeaux madzi (1%).
Downy mildew ( peronosporosis ) yakhala yowopsa komanso yoopsa matenda a nkhaka mu wowonjezera kutentha. Kaŵirikaŵiri amapezeka kumayambiriro kwa August pambuyo kusintha kwakukulu kutentha, mphamvu condensation pa filimu kapena kuthirira ndi madzi ozizira. Choyamba, mawanga obiriwira amaoneka pamasamba, akuchulukira sabata, ndiye masamba amasanduka bulauni ngati atatentha ndikuuma pambuyo pa masiku awiri kapena atatu.
Njira zoletsa :
- kutha kwa kuthirira ndi kukwera pamwamba kwa masiku 6 mpaka 7;
- kupopera mbewu pambuyo pochepetsa chinyezi ndi kutentha (22-24 ° C) yankho la Topaz (1 buloule pa 10 malita a madzi);
- mpweya wokhala ndi wowonjezera kutentha, osalola kutentha kwake (masana 20-25 ° C, ndi usiku 18-22 ° C);
- Usiku, zomera zimaphimbidwa kuti zikhalebe kutentha.
Mavitamini a zamasamba amapezeka pamene amagwiritsidwa ntchito mu nthaka yotentha yomwe kale idagwiritsidwa ntchito popanga nkhaka, kutentha kwakukulu kwa kutentha ndi kubzala kosafunikira kwa mbande. Mungathe kudziwa kuti masamba a fruiting amayamba kutha, ndipo tsinde pa mizu yake imatembenuza chikasu ndi ming'alu.
Njira zoletsa:
- Mukamabzala, musamameretse mbande ndipo musatsanulire dziko lapansi m'chilimwe;
- Ngati mutapezeka, konzekerani yankho (kuchepetsa supuni 1 ya mkuwa sulphate, 3 tbsp choko kwa 0,5 l madzi) ndi kusungunula gawo lotayika la tsinde ku mizu;
- kuwononga zomera zomwe zakhudzidwa pamodzi ndi nthaka ndi kuwotcha, ndikutsanulira dzenje ndi yankho la mkuwa sulphate.
Komanso, mu nyengo ya kutentha kwambiri mu wowonjezera kutentha, nkhaka ingawononge imvi ndi yoyera (nkhungu) zowola .
Maonekedwe achikale (oyera) a nkhaka - matendawa omwe amawotcherera m'madzi otentha amawoneka ndi mawanga achikasu ndi oyera pa masamba ang'onoang'ono okhala ndi makwinya. Zimatsogolera kukula, kuchepa maluwa komanso mtundu wa zipatso. Mitengo yowonongeka iyenera kuwonongedwa, ndipo ena onse amangiriranso. Pofuna kupewa matendawa, m'pofunika kuti tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda.
Fusariosis wa nkhaka - matendawa amapezeka nthawi zambiri akamakula greenhouses. Zikuwonekera chikasu cha masamba pamene ovary akuwonekera, ndiye mkwapu umafota ndipo mbali ya pansi ya tsaya.
Njira zoletsa :
- kusamba kwa nthaka;
- Mbeu yambewu ndi biopreparation trichodermine (4g / makilogalamu) ndi kufalitsa kwake m'nthaka;
- Kusunga kutentha ndi chinyezi molondola mu wowonjezera kutentha;
- kuthirira madzi otentha (20 ° C).
- chiwonongeko cha baka.
Phytophthora pa nkhaka mu wowonjezera kutentha sizowoneka, zimatha kudziwika ndi maonekedwe a zobiriwira zobiriwira
Pamalo obiriwira pamasamba a nkhaka, matenda monga powdery mildew ndi bulauni (azitona) amawoneka, zomera zofooka, zomwe zingathetsedwe poyeretsa bwino nthaka ndi kutentha komweko pambuyo pa nyengo iliyonse ikukula.
Kusunga microclimate yoyenera mu wowonjezera kutentha ndi kusamala mosamala kudzakuthandizani kupewa matenda aliwonse a nkhaka zanu.
