Yekurima giredhi zinc sulphate monohydrate inogona kushandiswa seyakagadziriswa mvura-inogadziriswa uye kuteedzera chinhu fetiraiza kusimudzira kugoverwa kwehutano hwevhu nekusimudzira kukura kwezvirimwa.

Inogona kushandiswa kudzivirira zvirwere mumichero yemiti yemichero. Iyo zvakare inowanzo shandiswa fetiraiza yekuwedzera chirimwa zinc trace element mafetiraiza. Inogona kushandiswa seyakagadzika fetiraiza, foliar fetiraiza, nezvimwe.

1. Shandisa se fetiraiza yepasi:

Zinc sulfate inogona kushandiswa seyakagadzika fetiraiza kune dzakaomeswa zvirimwa senge chibage, gorosi, donje, kubata chibharo, mbatatisi, soya, nzungu, nezvimwewo Kazhinji, 1-2 kilograms yeZinc sulfate inoshandiswa paeka, uye 10-15 zviuru zvikaoma ivhu rakanaka rinoshandiswa. Mushure mekusanganisa mushe, musase zvakaenzana pasi, wozoirima muvhu, kana kurizora mumatehwe kana maburi. Muriwo unoshandisa maviri kusvika mana makirogiramu e zinc sulfate pa mu.

2. Foliar pfapfaidzo kunyorera:

1. Miti yemichero: pfapfaidza 3% ~ 5% zinc sulphate solution mwedzi mumwe isati yamera mukutanga kwechirimo, uye iyo yekumanikidza yekumanikidza inofanira kuderedzwa kusvika 1% ~ 2% mushure mekumera, kana kushandisa 2% ~ 3% zinc sulfate solution yegore Iwo matavi 1 ~ 2 nguva.

2. Muriwo: Mishonga yemashizha inoshandisa zinc sulphate solution ine huwandu hwe0.05% kusvika ku0,1%, uye mhedzisiro yekupfira padanho rekutanga rekukura kwemiriwo zviri nani, nguva yega yega kwemazuva manomwe, kuenderera uchimwaya 2 ~ katatu, imwe neimwe nguva per mu Spray 50 ~ 75 kg yemhinduro.

3. Mbeu inonyura kushandiswa:

Sanganisa zinc sulphate mumhinduro ine huwandu hwe0.02% kusvika 0.05%, wodira mbeu mumhinduro. Kazhinji, zvirinani kunyudza mbeu mumhinduro. Mbeu yemupunga yakanyoroveswa ne 0.1% zinc sulfate solution. Mbeu dzemupunga dzinotanga dzakanyoroveswa mumvura yakachena kweawa imwe, wozoiswa muzinc sulfate solution. Mbeu yemupunga yekutanga uye yepakati yakanyoroveswa kwemaawa makumi mana nemasere, uye mbeu yemupunga yekunonoka yakanyoroveswa kwemaawa makumi maviri nemana. Mbeu dzechibage dzakanyoroveswa mu0.02% ~ 0.05% zinc sulfate solution kwema6 ~ 8 maawa, uyezve dzinogona kudyarwa mushure mekubviswa. Mbeu dzegorosi dzakanyoroveswa mu0.05% zinc sulfate solution kwemaawa gumi nemaviri, uyezve dzinogona kudyarwa mushure mekubviswa.

Chechina, kushandiswa kwembeu kupfeka:

Shandisa 2 kusvika ku3 magiramu e zinc sulfate pakirogiramu yembeu, uiputse nemvura shomanana, pfapfaidza mbeu, uye fambisa uchimwaya. Mvura inofanira kushandiswa kusanganisa mbeu zvakaenzana. Mbeu dzinogona kudyarwa mushure mekunge dzaomeswa mumumvuri.
