Raws li kev nkag siab tseem ceeb hauv kev ua liaj ua teb tam sim no, agnochemicals ua txoj haujlwm tsis sib xws, txhim kho kev lag luam kev nyab xeeb, thiab txhawb kev txhim kho kom muaj kev sib cog lus ua ke. Los ntawm cov chiv thiab tshuaj tua kab rau cov yeeb yaj kiab ua liaj ua teb thiab kev loj hlob ua kom zoo nkauj los ntawm kev ua liaj ua teb tsim kev ua liaj ua teb cov lus cog qoob loo thiab ua tau zoo.
Kev chiv, ib qho tseem ceeb ntawm agnochemicals, muab cov khoom siv tseem ceeb xws li nitrogen, phosphorus, thiab poov tshuaj rau qoob loo loj hlob. Raws li kev txheeb cais, kev siv cov chiv kom raug tuaj yeem nce cov qoob loo thoob ntiaj teb los ntawm ntau dua 50%, ua tau zoo txo ntawm cov khoom noj khoom haus los ntawm cov pej xeem kev loj hlob. Tshuaj tua kab thiab kab mob thiab cov kab mob txo qis cov qoob loo poob. Kev siv tshuaj tua kab mob thoob plaws hauv ntiaj teb tiv thaiv 30% -40% ntawm txhua xyoo lis kev poob txhua xyoo poob. Tsis tas li ntawd, kev siv cov yeeb yaj kiab yas, xws li ua kom sov thiab noo noo ntau lawm, ua kev ua liaj ua teb ua ke thiab ua liaj ua teb txias thiab nthuav dav cov uas muaj av arable.
Niaj hnub nov ua liaj ua teb rau agnochemicals tsis muaj nyob rau hauv cov qoob loo tab sis kuj hauv lawv cov tsav ntawm precision thiab kev ua tau zoo. Piv txwv li, kev siv qeeb - Tshaj tawm chiv thiab biopesticides tau txo cov kuab paug thiab kev ua qias tuaj. Ntse worticies teatories, ua ke nrog cov khoom siv tshuaj lom neeg, muaj enabled sib txawv thiab cov nqi tshuaj tua kab, ntxiv txhim kho cov kev ua haujlwm ntawm kev ua liaj ua teb.
Txawm li cas los xij, kev siv kuab tshuaj ntawm kev ua liaj ua teb yog qhov tseem ceeb. Overreliance lossis kev siv tsis raug yuav ua rau muaj teeb meem xws li av degradation thiab dej muaj kuab paug. Yog li, qhov sib tw ua ke ntawm kev tswj kev tshawb fawb, thev naus laus zis kev tiv thaiv, thiab ib puag ncig kev tiv thaiv yog qhov tseem ceeb los ua kom muaj txiaj ntsig zoo ntawm cov tshuaj ua liaj ua teb. In the future, with the advancement of green chemical technology, agricultural chemicals will not only ensure global food security, but also better meet the development needs of ecological agriculture, providing solid support for the sustainable development of human society.
