SINGLE SUPER PHOSPHATE

Tsananguro Pfupi:

Superphosphate inonziwo general calcium phosphate, kana general calcium kwenguva pfupi. Ndiro rudzi rwekutanga rwefosfetiiza inogadzirwa munyika, uye zvakare irworudzi rwefosifeti fetiraiza inoshandiswa zvakanyanya munyika medu. Iyo inoshanda phosphorus zvemukati zve superphosphate zvinosiyana zvakanyanya, kazhinji pakati pe12% kusvika 21%. Yakachena superphosphate yakasviba grey kana off-chena hupfu, zvishoma kusviba, nyore kutora mwando, nyore kuunganidza, uye kupisa. Mushure mekunyungudutswa mumvura (iyo isina insoluble chikamu igypsum, inoverenga ingangoita 40% kusvika 50%), inova acidic inokurumidza-kuita phosphate fetiraiza.
mashandisirwo
Superphosphate inokodzera zvirimwa zvakasiyana uye nevhu rakasiyana. Iyo inogona kuiswa kune isina kwazvakarerekera, calcareous phosphorus-isina kukwana ivhu kudzivirira kutonhodza. Inogona kushandiswa seyakagadzika fetiraiza, yepamusoro kupfeka, mbeu fetiraiza uye midzi yepamusoro kupfeka.
Kana superphosphate ichishandiswa se fetereza yepasi, chiyero chekushandisa pammu chimwe chinogona kunge chingangoita 50kg pammu yevhu isina phosphorus inowanikwa, uye hafu yacho inosaswa zvakaenzana pamberi penyika yakarimwa, ichibatanidzwa pamwe neiyo yakarimwa se fetereza yepasi. Usati wadyara, kusasa imwe hafu zvakaenzana, sanganisa pamwe nekugadzirira kwepasi uye wozora zvakadzika muvhu kuti uwane kuiswa kwakapetwa kwe phosphorus. Neiyi nzira, iyo fetiraiza mhedzisiro ye superphosphate iri nani, uye chiyero chekushandisa kwezvayo zvinobudirira zvigadzirwa zvakare zvakakwirira. Kana ikasanganiswa nefotereza yepasi se fetiraiza yepasi, chiyero chekushandisa che superphosphate pammu chinofanira kunge chiri 20-25kg. Dzakadzika nzira dzekushandisa dzakadai sedhi application uye acupoint application dzinogona zvakare kushandiswa.

SSP yakakodzera zvirimwa zvakasiyana uye nevhu rakasiyana siyana. Iyo inogona kuiswa kune isina kwazvakarerekera, calcareous phosphorus-isina kukwana ivhu kudzivirira kutonhodza. Inogona kushandiswa seyakagadzika fetiraiza, yepamusoro kupfeka, mbeu fetiraiza uye midzi yepamusoro kupfeka. Kana SSP ichishandiswa se basal fetiraiza, huwandu hwekushandisa pam mu imwe hunogona kunge hunosvika makumi mashanu em kg imwe mu mu yevhu isina phosphorus inowanikwa, uye hafu yevhu rinorimwa rakasaswa zvakaenzana nyika yekurima isati yashandiswa se fetereza yepasi. Usati wadyara, kusasa imwe hafu zvakaenzana, sanganisa pamwe nekugadzirira kwepasi uye wozora zvakadzika muvhu kuti uwane kuiswa kwakapetwa kwe phosphorus. Neiyi nzira, iyo fetiraiza mhedzisiro yeSSP iri nani, uye chiyero chekushandisa kwezvayo zvinobudirira zvigadzirwa zvakare zvakakwirira. Kana ikasanganiswa nefotereza yepasi se fetiraiza yepasi, chiyero chekushandisa che superphosphate pammu chinofanira kunge chiri 20-25kg. Dzakadzika nzira dzekushandisa dzakadai sedhi application uye acupoint application dzinogona zvakare kushandiswa. Inogona kupa phosphorus, calcium, sarufa nezvimwe zvinhu kune zvirimwa, uye ine mhedzisiro yekuvandudza alkaline ivhu. Inogona kushandiswa seyakagadzika fetiraiza, yekuwedzera-midzi topdressing, uye foliar kupopera. Yakasanganiswa nenitrogen fetiraiza, ine mhedzisiro yekugadzirisa nitrogen uye kudzikisa kurasikirwa kwe nitrogen. Inogona kusimudzira kumera, kukura kwemidzi, kubazi, kubereka uye kukura kwezvirimwa, uye inogona kushandiswa senge mbishi yekugadzira fotereza yemubatanidzwa. Inogona kudzikisira kusangana kwe superphosphate nevhu, zvinobudirira kudzivirira soluble phosphorus kubva pakushanduka kuita insoluble phosphorus uye kudzikisira kushanda kwefetiraiza. Superphosphate uye organic fetiraiza zvakasanganiswa muvhu kuti zvigadzire zvakasununguka. Mvura inogona kupinda nyore nyore kuti inyungudise iyo inogadziriswa phosphorus. Iyo midzi acid uye organic fetiraiza yakavanzika nemidzi yemidzi yemuti inononoka kuita pane isingasviki calcium calciumate panguva imwe chete. Calcium carbonate inonyungudika zvishoma nezvishoma, zvichidaro ichivandudza mashandisirwo eiyo phosphorus muSSP. Kusanganisa SSP ne organic fetiraiza kunogona zvakare kushandura imwechete yekudyara kuita mukomboni fetiraiza, iyo inowedzera mhando dzezvinhu zvinoshandiswa kumiti, uye inosimudzira kunwiswa nekushandiswa kwe phosphorus nezvirimwa, izvo zvinosangana zvirinani nezvinodiwa zvinovaka muviri zvezvirimwa.
