Kugwiritsa ntchito mankhwala poletsa tizirombo ndi kuonjezera zokolola pa kulima mbewu zilizonse za masamba nthawi zonse zimasiya zolemba zonse za nthaka ndi zipatso zomwe zimapezeka. Izi mwachibadwa zimakhudza thanzi la anthu omwe amawagwiritsa ntchito, choncho alimi akuyesera kugwiritsa ntchito njira zachilengedwe kapena njira zosatetezera pothetsa zolingazi. Pa izi, njira zosagwiritsidwa ntchito nthawi zina amagwiritsidwa ntchito, mwachitsanzo - boric acid .
Kodi n'zotheka kuwaza tomato ndi boric acid?
Inde, inde, chifukwa chiri mukonzekerayi muli ndi zofunika kuti tomato azitulutsa zipatso zonse - boron. Kugwiritsa ntchito mapulogalamu apamwamba a foliar (kupopera mbewu mankhwalawa) kuti apindule zomera ndi izo zimalimbikitsa kugwirizanitsa mofulumira. Koma mankhwalawa akulimbikitsidwa kokha nthawi zina.
Kodi tomato akhoza kuwaza ndi asidi asidi?
Mitengoyi imathandiza chomeracho kuchotsa zinthu zomwe zimayenera kuti zikhale bwino kuchokera pansi pa nthaka, pambali pake zimalimbikitsa kukula kwa masamba ndi mapangidwe a mazira. Ndicho chifukwa chake tikulimbikitsidwa kuti tiwonjezeko phokoso ndi asidi kangapo pa nyengo:
- maluwa asanakhazikitsidwe;
- nthawi ya maluwa;
- mu nthawi ya fruiting.
Kubwereza kukonza sikungakhalepo kale kuposa masiku 8-10. Ngati, pambuyo pa feteleza yoyamba, zomera zinayamba kuoneka zoipa, ndiye kugwiritsa ntchito mankhwalawa kuyenera kuimitsidwa palimodzi.
Kuwonjezera phindu la boric acid lidzakuthandizira kuchulukitsa chiwerengero cha maluwa, sungani mabulu omwe apangidwa kale pamtunda ndikuletsa kuola zipatso. Zikachitika, kuwonjezeka kwa masamba okoma ndi 20% komanso kusintha kwa kukoma kwawo (kumakhala shuga wambiri) kumatchulidwa.
Komanso, chithandizochi chingathandize kupewa chitukuko cha matenda a phwetekere monga phytophthora. Pachifukwachi, amafunika kuchiritsidwa mu theka lachiwiri la June pa sabata atapopera mankhwalawa ndi mphamvu yochepa ya potaziyamu permanganate , ndipo pambuyo pake ayodini iyenera kugwiritsidwa ntchito.
Kodi ndi bwino bwanji kufalitsa tomato ndi boric acid?
Njirayi ndi yophweka. Choyamba, yankho limapangidwa, ndipo utatha utakhazikika, zomera zimaperedwa pa mlingo umodzi wa lita imodzi pa 10 m & sup2. Chotsatira chake, ziyenera kuti masamba ndi mazira a pa tchire ayenera kuthira bwino.
Malinga ndi cholinga chogwiritsira ntchito, pali njira zingapo zomwe mungakonzekeretse yankho la boric acid kuti musamalire tomato:
- Kusunga mazira. Galamu imodzi ya asidi imasungunuka bwino m'madzi otentha. Zotsatira zake zatsimikizika. Pambuyo pake, onjezerani madzi ozizira, kuti voliyumu yonse ndi 1 lita; 5-10 g wa mankhwala amatsanulira 10 malita a madzi ndi osakaniza.
- Kuti mutetezedwe kumatope a phytoplores. Timatsanulira 1 tsp. boric asidi mu chidebe cha malita 10 a madzi ndikusakaniza mpaka utasungunuka kwathunthu.
Ndikofunika kukonzekera zovala zapamwamba kuti tomato azisamala kwambiri, chifukwa kuchuluka kwa boron kumakhudza zomera. Ngati
Kupopera tomato ndi boric acid kumalimbikitsidwa nthawi yopanda nthawi (m'mawa kapena madzulo) popanda mphepo ndi mvula. Gwiritsani ntchito utsi ndi utsi wabwino.
Kudziwa zomwe zimadetsedwa ndi tomato, kuti muwonjezere mtundu ndi kuchuluka kwa mbeu, kuphatikizapo mankhwala amtundu, mukhoza kupeza masamba ambiri omwe angaperekedwe ngakhale kwa ana.
