Ntau tus neeg yuav sib cav tias cov qab zib tsim cov suab thaj zoo dua tab sis nws tsuas yog loj hlob hauv thaj chaw sov. Yog tias koj muaj hmoo txaus los nyob hauv ib cheeb tsam uas sov txhua xyoo, tus tswv cuab ntawm cov nyom no tuaj yeem lom zem kom loj hlob thiab tsim cov khoom qab zib zoo nkauj. Nrog rau qhov chaw xaiv thiab kev saib xyuas dav dav, koj yuav tsum paub yuav ua li cas fertilize qab zib. Cov kev xav tau ntawm cov khoom noj qab zib yuav txawv me ntsis nyob ntawm cov av, yog li nws yog qhov zoo tshaj los ua qhov ntsuas av ua ntej pib ntawm kev pub mis.

Sugarcane Fertilizer and Macro-nutrients

Kev tshawb fawb tau pom tias cov khoom noj qab zib tseem ceeb yog nitrogen, phosphorus, magnesium, sulfur thiab silicon. Qhov tseeb ntawm cov as-ham no nyob ntawm koj cov av, tab sis tsawg kawg nws yog qhov chaw pib. Cov av pH yuav cuam tshuam rau cov nroj tsuag muaj peev xwm nqus tau thiab ntxiv cov as-ham thiab yuav tsum yog 6.0 txog 6.5 kom tau txais txiaj ntsig zoo.

Lwm yam yuav cuam tshuam rau qhov tseeb ntawm cov as-ham absorbed, xws li cov av hnyav, uas tuaj yeem txo qis kev nqus ntawm nitrogen. Yog tias txhua yam raug txiav txim siab thiab hloov kho, cov lus qhia dav dav ntawm kev pub cov nroj tsuag qab zib yuav pab tsim cov phiaj xwm chiv txhua xyoo.

Thaum obcov macronutrients tseem ceeb yog qhov tsim nyog heev rau kev tsim cov suab thaj, potassium tsis yog qhov teeb meem ntawm kev txhawj xeeb. Raws li cov nyom, tus naj npawb ntawm cov khoom noj uas tsim nyog thaum fertilizing qab zib yog nitrogen. Ib yam li koj cov nyom, cov kab tsib yog cov neeg siv nitrogen hnyav. Nitrogen yuav tsum tau siv ntawm 60 mus rau 100 phaus ib acre (27 mus rau 45 kilos /.40 ha). Tus nqi qis dua yog rau cov av sib dua thaum tus nqi siab dua yog nyob rau hauv cov av hnyav.

Phosphorus yog lwm yam macronutrient qab zib chiv yuav tsum muaj. Tus nqi pom zoo yog 50 phaus ib acre (23/.40 ha). Kev sim av txhawm rau txheeb xyuas tus nqi tiag tiag yog qhov tseem ceeb vim tias ntau tshaj phosphorus tuaj yeem ua rau xeb.

Npaj Sugarcane Plants Micro-nutrients

Ntau cov micronutrients muaj nyob rau hauv cov av, tab sis thaum qoob loo, cov no tau depleted thiab yuav tsum tau hloov. Kev siv cov sulfur tsis yog cov khoom siv ntxiv tab sis yog siv los txo cov av pH qhov tsim nyog txhawm rau txhim kho kev nqus ntawm cov as-ham. Yog li ntawd, nws yuav tsum tsuas yog siv tom qab kuaj pH los kho cov av.

Ib yam li ntawd, silicon tsis tseem ceeb tab sis tuaj yeem ua tau zoo. Yog tias qhov ntsuas av qis, cov lus pom zoo tam sim no yog 3 tons ib acre/.40ha. Magnesium tuaj yeem los ntawm dolomite kom tswj cov av pH tsawg kawg yog 5.5.

Tag nrho cov no yuav tsum tau kuaj av kom pom cov zaub mov zoo thiab tuaj yeem hloov pauv txhua xyoo.

Yuav Fertilize Sugarcane

Thaum koj pub cov suab thaj tuaj yeem txhais tau tias qhov sib txawv ntawm qhov muaj txiaj ntsig zoo thiab ib qho uas tsis muaj sijhawm. Fertilizing qab zib ntawm lub sijhawm tsis raug tuaj yeem ua rau hlawv. Thawj lub teeb fertilizing yog ua tiav thaum canes nyuam qhuav tuaj. Qhov no yog ua raws li kev siv nitrogen ntau ntxiv hauv 30 mus rau 60 hnub tom qab cog.

Pub zaub txhua hli tom qab ntawd. Nws yog ib qho tseem ceeb kom cov nroj tsuag zoo watered tom qab pub mis kom pab cov as-ham percolate rau hauv av thiab txhais mus rau hauv paus. Organic manures yog ib txoj hauv kev zoo los muab cov nroj tsuag cov nitrogen txhawb lawv xav tau. Cov no yuav tsum tau siv tsawg dua, vim lawv siv sijhawm los ua kom tawg. Siv raws li ib sab hnav khaub ncaws raws cov qoob loo cov hauv paus paj.
