Ukuxuba isilinganiso se-sodium nitrophenates kanye norea njengomanyolo wesisekelo kanye nomanyolo we-toplerressing

① Isisekelo sokuxuba somanyolo

I-Sodium nitrophenolates kanye ne-Urea kuxutshwe njengomanyolo wesisekelo, okungukuthi, ngaphambi kokuhlwanyela noma ukutshala. Isilinganiso sokuxuba yile: 1.8% sodium nitrophetolate (20-30 amagremu), amakhilogremu angama-45 e-urea. Kule ngxube, i-acre eyodwa ngokuvamile yanele. Ngaphezu kwalokho, inani le-urea lingashintshwa ngendlela efanele, ikakhulukazi ngokuya ngezimo zenhlabathi.

② Isilinganiso sokuxuba okuphezulu

Mayelana nesilinganiso sokuxuba sokwehla, kukhona nezindlela ezimbili ezihlukile: inhlabathi ethosiwe yenhlabathi kanye ne-foliar toplerressing.

Okokuqala, indlela yenhlabathi yenhlabathi, isilinganiso sokuxubana singu-1.8% sodium nitrophenolates (5-10 ml g) namakhilogremu angama-35 e-urea. Le formula ye-ratio nayo cishe nge-1 acre. I-TopDerressing yenhlabathi isebenzisa lesi silinganiso sokuxuba, futhi kunconywa ukusebenzisa indlela engcwatshwe, ezoba nomphumela ongcono.

Okwesibili, indlela yomanyolo yomanyolo we-foliar, isilinganiso sokuxuba yilezi: 1.8% Sodium nitrophenotates (3 ml g), amagremu angama-50 e-urea, namakhilogremu angama-60 amanzi.

Kodwa-ke, ukufafaza kuyazwela isikhathi sokukhula kwezilimo, futhi kufanele kusetshenziswe esikhathini sokukhula esihle kakhulu semiphumela engcono. Isibonelo: Esigabeni sesithombo, izimbali eziqhakaza kanye nesiteji sezithelo, kanye nesiteji sokuvuvukala, ukufafaza kanye ngesikhathi sokukhula ngakunye kuzoba nomthelela ongcono ekukhuleni ukukhula.

Isifinyezo: Umphumela wokuxuba i-sodium nitrophenates kanye norea impela 1 + 1 mkhulu kuno-2. Urea ngumanyolo we-nitrogen onobukhulu be-nitrogen, futhi i-sodium nitrofenolates isisombululo esihle kakhulu sokulawulwa kokukhula kwesitshalo. Ukusetshenziswa okuhlanganisiwe kwe-urea ne-sodium nitrophenates kungakhulisa ngokushesha izinga le-photosynthetic lamaqabunga, ngcono kakhulu izinga lokusetshenziswa komanyolo we-nitrogen, futhi ukhulisa kakhulu ukukhiqizwa. Ibizwa ngokuthi "umlingani wegolide" noma "ifomula legolide" lomanyolo kanye ne-pesticide ehlanganisa.
