Mbande za sitiroberi ndi kubzala zimafunikira magawo omwe ali ndi zinthu zabwino zosungira madzi, monga ubweya wa miyala ndi chinangwa cha kokonati.
Mu siteji ya nazale, kutentha kwa kumera ndi 20-25.
Strawberries amakonda kuwala kochuluka, makamaka kuposa theka la tsiku.Malo a mpweya wabwino.
Strawberries salekerera chilala, mawanga a bulauni amawonekera pamasamba akawuma, zomwe zidzakhudzanso chipatsocho.Choncho, madzi okwanira amafunika.Ikani feteleza wamadzi kamodzi pa milungu iwiri iliyonse, ndipo chiŵerengero cha nayitrogeni, phosphorous, ndi potaziyamu ndi 5:10:5.
Chifukwa chake, kulima strawberries mu wowonjezera kutentha kumatha kuthana ndi mavutowa bwino.
1. Malangizo ena olima strawberries mu wowonjezera kutentha
Kuthirira ndi kuthirira kungathe kubweretsa phindu lalikulu kwa sitiroberi mu wowonjezera kutentha.
Kusiyanitsa kwa maluwa kumafuna kutentha kochepa komanso masana ochepa.Ukonde wa sunshade ukhoza kuphimbidwa kunja kwa wowonjezera kutentha.Pangani zinthu zamasiku ochepa komanso kutentha kochepa.Limbikitsani kusiyanitsa kwa apical inflorescence ndi axillary inflorescence.
Ntchito yotulutsa mpweya wabwino.Chinyezi cha nthaka pakukula kwa mbande za sitiroberi chiyenera kukhala 70% -80%.Chinyezi mu anakhetsa ayenera kukhala 60% -70%.Choncho, pamene kutentha kwa shedi kupitirira 30 ° C, mpweya wabwino uyenera kuchitika.Ntchito ina ya mpweya wowonjezera kutentha ndikupewa sitiroberi powdery mildew.
2. Kuletsa matenda
2.1.Matenda a mawanga a masamba
Matenda a mawanga a masamba: Amadziwikanso kuti matenda a diso la nyoka, amawononga makamaka masamba, ma petioles, tsinde la zipatso, tsinde lanthete ndi njere.Mawanga ofiirira amapangidwa pamasamba, omwe amakula mpaka kupanga zotupa zozungulira kapena zozungulira, zokhala ndi m'mphepete zofiirira-zofiirira, zotuwa pakati, zozungulira pang'ono, zomwe zimapangitsa kuti chilonda chonsecho chiwoneke ngati maso a njoka, ndipo palibe chakuda chaching'ono. particles amapangidwa pa chotupa.
Njira zowongolera: chotsani masamba odwala munthawi yake ndi masamba akale.Gwiritsani ntchito 70% ya ufa wa chlorothalonil wonyowa nthawi 500 mpaka 700 wamadzimadzi atangoyamba kumene matenda, ndi kupoperani pakatha masiku khumi.Kapena gwiritsani ntchito 70% ufa wonyowa wa mancozeb ndikupopera magalamu 200 amadzi ndi ma kilogalamu 75 pa mu.
2.2.Ufa nkhungu
Powdery mildew: Imawononga makamaka masamba, komanso imakhudza maluwa, zipatso, tsinde la zipatso ndi petioles.Mipukutu yamasamba imakhala ngati kapu.Maluwa osweka ndi ma petals ndi ofiirira-ofiira, osatha kuphuka kapena kuphuka kwathunthu, chipatsocho sichimakulitsidwa, koma chotalikirana;chipatso chaching'ono chimataya kuwala ndipo chimakhala cholimba.Ngati sitiroberi yomwe yatsala pang'ono kukhwima iwonongeka, idzataya phindu lake lamalonda.
Njira zowongolera: yang'anani kupopera mbewu mankhwalawa Baume 0,3% laimu wosakaniza wa sulfure mkati ndi kuzungulira chomera chapakati cha matenda.Pambuyo kukolola, dimba lonse limadula masamba, kupoperani 70% thiophanate-methyl nthawi 1000, 50% Teflon nthawi 800, 30% Teflon nthawi 5000, ndi zina zotero.
2.3.Gray nkhungu
Gray nkhungu: Ndilo matenda aakulu pambuyo pa maluwa, omwe amatha kukhudza maluwa, masamba, zipatso ndi masamba.Brown mawanga aumbike pa zipatso mu kutupa siteji ndipo pang`onopang`ono kuwonjezera.Kwambiri imvi nkhungu imapangitsa chipatso kukhala chofewa komanso chowola, chomwe chimakhudza kwambiri zokolola.
Njira zowongolera: utsi 25% carbendazim ufa wonyowa nthawi 300 zamadzimadzi, 50% gramendazim wonyowa ufa 800 nthawi zamadzimadzi, 50% baganin 500-700 nthawi zamadzimadzi, ndi zina zambiri.Kuwola kwa mizu: Kuyambira m'munsi mwa tsamba, tsamba la m'mphepete mwake limakhala lofiirira, pang'onopang'ono kufota mmwamba, ngakhale kufota.Pakati pa zipilalazo zinayamba kukhala zofiirira ndi zowola, ndipo zipilala zapakati pa mizu zinali zofiira.Njira zowongolera: Musanasinthire strawberries, gwiritsani ntchito njira ya 40% katsitsumzukwa wobiriwira nthawi 600, kuthira m'mphepete, ndikuphimba nthaka ndikuyika bwino kuti muphe majeremusi m'nthaka, kuchepetsa mizu ya majeremusi akumunda. , ndi kuchepetsa mwayi wotenga matenda.
AX high tunnel wowonjezera kutentha
Mu mndandanda wa AXgreenhouse mkulu ngalande wowonjezera kutentha.The shading dongosolo, mpweya mpweya, dongosolo ulimi wothirira, sprinkler dongosolo, etc. akhoza mwanzeru kulamulira wowonjezera kutentha, kupanga linanena bungwe chandamale.
Tili ndi mpweya wozungulira wozungulira mumsewu wowonjezera kutentha, magetsi ndi njira zamanja zilipo.
Makina opopera amatha kukwaniritsa ntchito zingapo zamoisturizing ndi kupopera mbewu mankhwalawa.Malizitsani ntchito mu wowonjezera kutentha nthawi imodzi
