Kev taw qhia txog kev sib xyaw ntawm dej thiab chiv
Lub npe hu ua kev sib xyaw dej thiab chiv yog hais txog ib txoj kev fertilizing thiab watering qoob loo los ntawm cov kav dej. Yog li ntawd, ob qho tib si irrigation dej thiab chiv dhau los ntawm tib irrigation system mus rau hauv paus qoob loo. Kev sib xyaw dej thiab chiv feem ntau yog siv rau hauv micro-irrigation systems thiab tseem tuaj yeem siv rau hauv cov twj tso kua dej mobile. Hauv kev lag luam horticulture (txiv hmab txiv ntoo, zaub thiab cov qoob loo ornamental), drip irrigation feem ntau yog siv los ua ib txoj kev sib xyaw ntawm dej thiab chiv. Qhov loj-scale, ceev thiab nruam saws ntawm drip irrigation systems nyob rau hauv lub horticulture sector kuj txhawb kev txhawb nqa ntawm dej thiab chiv kev koom ua ke.
Los ntawm kev sib koom ua ke ntawm cov dej thiab cov chiv, cov chiv tuaj yeem txo qis thiab kev siv cov tshuab fertilization nquag tuaj yeem zam tau. Muaj ntau qhov txiaj ntsig zoo rau kev sib txuas cov dej thiab cov chiv sib xyaw nrog cov dej ntws los yog cov txheej txheem dej txau siab heev.
Cov txiaj ntsig no suav nrog:
① Txhim kho cov qoob loo dej thiab cov chiv siv kev ua haujlwm zoo.
② Yog tias tsim nyog, cov chiv tuaj yeem siv ncaj qha mus rau hauv paus cheeb tsam ntawm cov qoob loo los ntawm drip irrigation.
③ Dej thiab chiv tuaj yeem siv tau raws li cov qoob loo xav tau.
④ Txhim kho cov dej thiab kev tswj cov khoom noj kom haum rau cov kev xav tau tshwj xeeb ntawm cov qoob loo (geography, climates).
⑤ Txo cov dej thiab cov chiv siv thiab txo qhov cuam tshuam tsis zoo rau ib puag ncig.
⑥ Piv nrog rau kev siv tshuab fertilization, fertilization nqi thiab sij hawm yuav cawm tau.
⑦ Muaj peev xwm muab kev tawm tswv yim sai sai ntawm kev cog qoob loo ntau dhau lossis tsis txaus thiab / lossis dej
⑧ Kev cog qoob loo thiab cov khoom lag luam zoo tuaj yeem txhim kho los ntawm kev ua kom zoo dua dej thiab chiv.
⑨ Cov qib ntawm cov av compaction tuaj yeem txo vim qhov txo qis hauv kev siv cov tshuab hnyav thiab khoom siv.
Txhawm rau kom ua haujlwm tau zoo thiab ruaj khov, cov hauv qab no yuav tsum muaj rau kev tswj hwm dej thiab chiv:
① Xaiv thiab tsim kom muaj kev sib xyaw ua ke ntawm cov dej thiab cov chiv lossis cov kav dej.
② Cov dej zoo yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm cov dej thiab cov chiv sib xyaw ua ke los yog cov kav dej
③ Cov chiv yuav tsum tau ua tib zoo xaiv thiab tswj kom tsis txhob muaj kev tawm tsam ntawm cov as-ham (xws li phosphorus thiab calcium) thiab thaiv cov emitters.
Muaj ntau qhov sib txawv ntawm cov dej thiab cov chiv sib xyaw ua ke, txhua tus tuaj yeem muab cov chiv rau cov qoob loo nrog cov dej irrigation thiab ua tau raws li qhov xav tau ntawm fertilization thiab irrigation tib lub sijhawm. Cov tshuab no muaj xws li los ntawm kev yooj yim bypass fertilization tso tsheb hlau luam mus rau tag nrho cov dej tsis siv neeg thiab cov chiv sib xyaw ua ke. Lub bypass fertilization tank yog lub tshuab ua chiv tso rau hauv lub tank, thiab tom qab ntawd cov dej hauv dej yog tswj los ntawm lub tank fertilization kom ntseeg tau tias ib lossis ntau tshaj cov chiv tuaj yeem siv tau. Lub tshuab ua kua dej tsis siv neeg ua ke ua ke yog tswj los ntawm lub computer. Lub kaw lus, nyob rau hauv tag nrho cov txheej xwm irrigation, muaj peev xwm txhaj tshuaj concentrated chiv rau hauv ob los yog ntau tshaj tank loj (txhua muaj ib, ob los yog ntau tshaj dej-soluble chiv), thiab muab rau cov qoob loo nyob rau hauv ib tug computer-tswj yam. Tsim nyog, ua kom tiav cov as-ham thiab tshwj xeeb concentration nutrient tov.Nyob rau hauv lawv daim ntawv siab tshaj plaws, cov tshuab automated no tuaj yeem siv los rov ua dua qub cawv los ntawm substrate cultivation thiab kho qhov muaj pes tsawg leeg ntawm cov tshuaj siv dua. Nyob rau hauv nruab nrab ntawm ob qhov kev sib xyaw dej thiab chiv tshuab, muaj ntau lub tshuab nrog ntau theem ntawm complexity thiab automation. Yuav luag tag nrho cov tshuab siv qee hom lim kom txo tau qhov kev pheej hmoo ntawm cov khoom txhaws cov drippers thiab cov kav dej. Tam sim no, muaj ntau yam khoom siv rau kev sib xyaw dej thiab chiv, thiab kuj muaj ntau yam ntawm cov khoom siv no, yog li muaj ntau yam xaiv los ntawm.
Cov txheej txheem kev khiav hauj lwm yooj yim tuaj yeem ua tau raws li ib qho kev thov chiv ntawm cov dej sib xyaw thiab cov chiv (xws li kev hnav khaub ncaws saum toj kawg nkaus rau ib, ob lossis ntau qhov chiv), lossis siv rau kev ua qoob loo ntxiv thaum xav tau tshwj xeeb. Fertilizer siv li no feem ntau yog siv los ua ib qho ntxiv rau cov pa fertilization, uas yog ua tiav nrog lub tsheb laij teb-tsav fertilizer spreader. Nyob rau hauv lub computer tswj systems, feem ntau muaj ob los yog ntau tshaj concentrated chiv tov, ob qho tib si ntawm uas yog ntxiv los ntawm ib tug integrated dej thiab chiv pipeline. Cov chiv yooj yim tso tsheb hlau luam tuaj yeem siv rau kev ua kom nquag plias, tab sis kev ua haujlwm yuav tsum muaj ntau dua, thiab cov chiv tsis sib xws yuav tsum tau muab tso rau hauv cov khoom siv.
Tag nrho cov dej thiab chiv kev koom ua ke yuav tsum tau hloov kho kev xaiv ntawm cov cuab yeej siv thiab thev naus laus zis kom hloov mus rau qhov xav tau ntawm txhua theem kev tswj hwm. Kev hais lus dav dav, kev sib koom ua ke ntawm cov dej thiab cov khoom siv chiv muaj xws li cov theem hauv qab no: ① Kev hloov pauv dej.
② Cov dej cia-- khaws cov dej thiab cov dej khib nyiab,
③ Kev cog qoob loo lossis kev xaiv substrate.
④ Npaj dej rau kev siv dej los yog dej thiab cov chiv ua ke.
⑤ Khoom noj khoom haus ntxiv.
⑥ Siv rau cov qoob loo los ntawm cov kav dej.
⑦ Kev tswj cov qoob loo.
⑧ Kev tswj qoob loo.
⑨ Kev kho cov kab mob, salinity thiab as-ham tom qab tus Tsov tus tw rov qab ua kua
