Kusamalira udzu - malangizo oti mbewu za udzu zimere mwachangu

Pali njira ziwiri zokulirambewu za udzu:

1. Kumera kwa kutentha kwambiri, komwe kumagwiritsidwa ntchito kutentha kukakhala kochepa, kumatha kuwonjezera nthawi yobzala ndi masiku 10 mpaka 15.

2. Kumera kwa kutentha kwabwinobwino, komwe kumagwiritsidwa ntchito nthawi yanthawi yobzala, kungathandizenso kumera bwino ndikuchepetsa ntchito yosamalira mbande.

Mbeu zikamera, zimamera mwachangu ndipo zimakhala zabwino. Chifukwa cha kuchuluka kwa kumera, kuchuluka kwa kubzala mbewu kumatha kuchepetsedwa ndi 20-25%. Nthawi yomweyo, chifukwa cha nthawi yochepa yomera, ntchito yothirira mbande imachepa.

Malo ogwirira ntchito yomera

1. Zilowetseni mbewu zouma m'madzi kwa ola limodzi kapena awiri poyamba. Mbewu za udzu wa nyengo yozizira zitha kunyowa m'madzi ozizira kapena madzi ofunda pang'ono.

2. Mbewu zikachotsedwa, ziyenera kusakanizidwa ndi mchenga woyera wa mumtsinje wopanda zinyalala pa chiŵerengero cha kuchulukitsa kuwirikiza 20 kuchuluka kwa mbewu, ndikuzisakaniza mofanana. Mukagwira mbewu m'dzanja, ndibwino kuti madzi asalowe pakati pa zala (chiŵerengero cha mchenga wa mumtsinje chingakhale chocheperapo kapena chocheperapo, chochuluka chingathandize kubzala.

3. Pa nthawi yanthawi zonsenthawi yobzala, njira yomera ya kutentha kwabwinobwino imagwiritsidwa ntchito nthawi zambiri. Mbewu zosakanikirana ndi mchenga zimaunjikidwa pansi wamba kapena kuphimbidwa ndi mulch kuti zizikhala zofunda komanso zonyowa, zomwe zingathandizenso kuti zimere msanga.

4. Kutentha kukakhala kochepa, njira yokulira kutentha kwambiri imagwiritsidwa ntchito. Nthawi zambiri, mbewu zosakanikirana ndi mchenga zimayikidwa m'zidebe monga matumba a njoka ndi mabokosi amatabwa malinga ndi malo obzalamo a 100 sikweya mita, ndikuziyika mu greenhouse kuti zimere. Kutentha ndi nthawi yobzala zimasiyana malinga ndi mtundu wa udzu. Udzu wa nyengo yozizira uyenera kulamulidwa pa kutentha pafupifupi 28℃ ndipo nthawi zambiri uyenera kuyikidwa mumndandanda kwa masiku awiri kapena atatu.

5. Pa nthawi yomera ndi kubzala m'mizere, mphukira ziyenera kufufuzidwa kawiri patsiku. Ngati mbewu zina zapezeka kuti zili ndi "nsonga zoyera", ziyenera kufesedwa mwachangu. Kawirikawiri, mbewu za udzu za nyengo yozizira zimatha kuikidwa m'mizere kwa masiku atatu. Kaya ndi "zoyera" kapena ayi, ziyenera kufesedwa mwachangu kuti mbewu zisafe ndi nkhungu.

Kufesa

1. Mbewu zonyowa zomwe zamera ziyenera kufesedwa pamalo onyowa. Pambuyo pa mame am'mawa ndi madzulo ndi kuwala kwa dzuwa, zimamera mwachangu. Ngati mbewu zonyowa zomwe zamera zafesedwa pamalo ouma, kuchuluka kwa kumera kudzachepa chifukwa cha dzuwa ndi mphepo, choncho ndi bwino kufesa nthawi yamvula.

2. Malo obzala mbewu omwe alimidwa mozama komanso molinganizidwa bwino ayenera kuthiriridwa mozama theka la tsiku kapena tsiku limodzi musanabzale. Dothi lonyowa liyenera kukhala lopitirira 20 cm. Mwanjira imeneyi, mbewu zonyowa zimatha kumera patatha masiku angapo mutabzale. Chifukwa nthaka yomwe ili m'malo obzala mbewu ndi yonyowa, nthawi zambiri sikofunikira kuthira madzi mutabzale.

Njira yobzala mbewu zonyowa mutamera

1. N'zovuta kwambiri kubzala, kubzala ndi kuphimba nthaka pamalo akuluakulu. Kawirikawiri, malo obzala mbewu amagawidwa m'magawo 10.00 square meters ndi gawo lobzala, ndipo limagawidwanso m'magawo 100 square meters pobzala kuti zisasowe ndi kubwerezabwereza.

2. Mbewu za udzu ndi zazing'ono, kotero nthaka yonyowa imatha "kukokedwa" pang'onopang'ono ndi rake lokhala ndi mano ochepa musanabzale. Mbewu zikabzalidwa, mbewu zimatha kukokedwa ndi rake lokhala ndi mano ochepa kuti zigwere mu tinthu ta nthaka. Kapena, mbewu zomwe zabzalidwa pamwamba zitha kugwetsedwa mu mipata pakati pa tinthu ta nthaka pogwiritsa ntchito tsache la nsungwi kuti zikanikizire nthaka, kuti tinthu ta nthaka ndi mbewu zigwirizane kwambiri. Pambuyo pofufuza kambiri, mbewu zambiri zimatha kugwera mu mipata pakati pa nthaka pogwiritsa ntchito njira "zokokera pansi" ndi "zomenya pansi" zokokera ma rake kapena ma broom a nsungwi, zomwe zimagwira ntchito yophimba.
