Zimakhala zovuta kufotokozera mbali ya feteleza feteleza mu ulimi ndi ulimi wamaluwa. Nchifukwa chiyani akusowa feteleza feteleza? Kwa mbewu za m'munda, zimagwiritsidwa ntchito kuonjezera zokolola ndi kukana kutentha. Kuwonjezera potaziyamu kumapangitsa kuwonjezeka kwa kukana kwa chilala kwa zomera, zimapangitsa zipatso kukhala zosavuta m'nyengo yozizira. Mu tomato, zomwe zimakhudza kwambiri kusowa kwa potaziyamu, zisamapse ndipo zisakhale zobiriwira za chipatso pafupi ndi phesi.
Kodi feteleza amtundu wotani alipo?
Mavitamini a feteleza amachititsa kuti azisiyana. Kusiyanitsa feteleza wokhudzana ndi chlorini ndipo popanda. Kukhalapo kwa klorini kumasiyana ndi mitundu yosiyanasiyana ya feteleza ndipo kumasiyana mu chiwerengero. Choncho, chlorine yochuluka mu potassium chloride ndi 60%, ndiye potassium sulphate imapitirira 52%, ndipo mankhwala enaake a feteleza potaziyamu ndi 40%.
Popeza klorini ndi mankhwala oopsa ndipo ingakhudze chomeracho, feteleza ndi zowonjezera sizigwiritsidwe ntchito nthawi yamasika. Mtengo uwu wa feteleza umalowetsedwa m'nthaka kumapeto kwa autumn, kotero kuti m'nyengo yozizira klorini imatsukidwa ndi madzi amvula ndipo sawononga zomera. Chlorini imakhudzidwa kwambiri ndi Solanaceae - mbatata, tsabola, ndi phwetekere, choncho ndikofunikira kuti asankhe feteleza omwe alibe chlorine.
Musaiwale kuti kugwiritsa ntchito nthawi zonse ma chlorini feteleza kumabweretsa acidification wa nthaka pa tsamba. Pofuna kupewa izi, nthawi yomweyo feteleza isanandike, mandimu amawonjezeredwa kuti asatengeke.
Manyowa ovuta
Phosphoric-potashi ndi feteleza a nitrogen-potaziyamu ndizo mitundu yosiyanasiyana ya feteleza. Mapulogalamu awo osiyanasiyana amachititsa kukhala otchuka kwambiri pakati pa iwo omwe amalima mbewu za m'munda. Mwachitsanzo, potassium nitrate , yomwe yakhala ikudziwikiratu kwa fetereza zonse, ndi nayitrogeni wokhutira ndi feteleza yabwino kwambiri obiriwira. Manyowa abwino kwambiri a phosphorous-potaziyamu ndi superphosphate. Zimasungunuka bwino ndipo zingagwiritsidwe ntchito nthawi yonse ya chilimwe.
Manyowa a potaziyamu-magnesium - calimagnesium amathandiza kwambiri dothi la mchenga kumene mitundu ina ingakhale yopanda mphamvu.
Ambiri feteleza omwe amadziwikiratu kwa agogo athu ndi phulusa - komanso potashi feteleza. Kuwonjezera pa potaziyamu, phulusa ili ndi magnesium, phosphorous, chitsulo, mkuwa ndi zina. Phulusa likhoza kupangidwa mosasamala nyengo. M'nyengo yozizira, imaphatikizidwa asanayambe kukumba dziko lapansi, ndipo m'chilimwe phulusa limagwiritsidwa ntchito popanga pamwamba pa mawonekedwe onse owuma ndi a madzi.
Phulusa imagwiritsa ntchito zosiyanasiyana - zipatso, mitengo, mbatata ndi masamba. Chifukwa cha kashiamu, phulusa limagwiritsidwa ntchito kuchepetsa acidity m'nthaka.
Njira zogwiritsira ntchito
Manyowa a potaziyamu amchere amathandiza kwambiri, chifukwa amayamba kuchitapo kanthu atangomaliza feteleza. Sungani zouma zosakaniza ndi madzi molingana ndi malangizo
Manyowa otentha a potashi amapezeka makamaka m'nyengo yozizira kapena kumayambiriro kwa masika, pamene chisanu chimagwa. Ndiye, chifukwa cha chinyezi chakuda cha dothi, fetereza imayamba pang'onopang'ono.
Ngati zokolola sizikusonkhanitsidwa monga momwe tingafunire, ndiye kuti, nthaka yosauka ndiyo chifukwa. Nthaka yotero imayenera feteleza. Poyamba kuzigwiritsa ntchito, mwini mundayo adzipeza modabwa kuti zokolola zawonjezeka, ndipo ngakhale tizirombo ta m'munda ndi munda ndizochepa kwambiri. Chinthu chachikulu ndicho kuphunzira molondola, popanda kutengeka kuti mugwiritsire ntchito feteleza - anu anu pa zomera zonse.
