Pakutanga kwekushaikwa kwe potassium,chirimwa chehuswas inoratidza kukura zvishoma nezvishoma uye mashizha egirini rakasviba. Hunhu hukuru hwekushaikwa kwepotassium: kazhinji mashizha ekare nemipendero yemashizha zvinotanga zvaita yero, zvozotanga zvaita brown, zvakatsva uye zvakatsva, uye mavanga matema nematema anoonekwa pamashizha, asi pakati, mitsipa nenzvimbo dziri pedyo nemitsipa zvinoramba zvakasvibira. Sezvo mwero wekushaikwa kwepotassium uchiwedzera, shizha rese rinotanga kusviba kana kuoma, rinobuda rodonha; mamwe mashizha emiti akaita sebronze, akakombama pasi, aine matishu emesophyll akatumbuka pamusoro peshizha uye mitsipa yakanyura. Kana zvirimwa zvikasava nepotassium yakakwana, midzi yemiti inokuvadzwawo zvakanyanya, ine midzi mipfupi uye mishoma, inokurumidza kukwegura nguva isati yakwana, inoora muzviitiko zvakakomba, uye inogara panzvimbo yemidzi. Kana zvirimwa zveuswa zvikasava nepotassium yakakwana, mavanga matema anoonekwa pamashizha ezasi, uye muzviitiko zvakakomba, zviratidzo zvakafanana zvinoonekwa pamashizha matsva. Mashizha akapfava uye anorembera, madzinde acho akatetepa uye asina simba, uye internodes dzakapfupika; kana zvirimwa zvembeu zvikasava nepotassium yakakwana, girini repakati pemitsipa rinotanga kuoneka, rozobva raita yero, richiumba mashizha ane mavara. Muzviitiko zvakakomba, mipendero yemashizha inotsva uye inokotama pasi, uye madonhwe ebrown anokura mukati menzvimbo iri pakati petsinga. Chidimbu chemashizha chinorasikirwa nemvura uye chinokotama, pamusoro pemashizha panobva pakombama kana kuti pakona, uye zvishoma nezvishoma chinotsva uye chinodonha, uye chirimwa chinokura nguva isati yakwana.
Ndingaitei kana uswa husina potassium? Potassium haisi chinhu chakakosha chete pahupenyu hwezvirimwa, asiwo chimwe chezvinhu zvitatu zviri mufetereza. Potassium iri muzvirimwa inongotevera nitrogen. Kushandisa potassium fertilizer zvine mwero kunogona kuwedzera photosynthesis yemiti yehuswa uye kuramba kwayo kuzvirwere nezvipembenene. Kana zviratidzo zvekushomeka kwepotassium zvikaonekwa mukutarisira uswa, potassium fertilizer (yakadai se potassium chloride, potassium sulfate, potassium phosphate, nezvimwewo) inofanira kushandiswa kudzivirira nekudzora. Potassium chloride ne potassium sulfate zvese mafetiraiza anoshanda nekukurumidza anogona kushandiswa semafetiraiza ekutanga uyekuzadza pamusoroZvakanakisisa kushandisa potassium sulfate muvhu rine acidic uye potassium nitrate muvhu rine alkaline.
Kana uswa huine zviratidzo zvataurwa pamusoro apa, nzira dzinotevera dzinogona kushandiswa kugadzirisa dambudziko iri:
1. Isa fetereza yenitrogen shoma wobva wadiridza nekukurumidza mushure mekushandisa fetereza yenitrogen.
2. Shandisai zvinhu zvine maamino acids uye zvinhu zvidiki pakupfapfaidza, kunyanya pakuvandudza midzi uye kuwedzera zvinhu zvidiki.
3. Isa potassium sulfate 2kg/nguva.
