Kev saib xyuas cov nyom - yuav ua li cas los tsim kom muaj cov nyom zoo nkauj thiab txaus siab

1. Xaiv hom nyom
Kev xaiv cov nyom zoo yog thawj kauj ruam thiab tseem ceeb tshaj plaws rau kev ua kom cov nyom zoo. Yog tias koj nyob rau sab qaum teb, koj tuaj yeem xaiv cov nyom txias (bluegrass, tall fescue, ryegrass, red fescue, bentgrass, thiab lwm yam); yog tias koj nyob rau sab qab teb, koj tuaj yeem xaiv cov nyom sov (Cyperus dentata, Bahia nyom, Zoysia japonica thiab Dianthus chinensis, thiab lwm yam). Cov cheeb tsam Jiangsu, Zhejiang thiab Shanghai uas peb nyob yog thaj chaw hloov pauv, thiab ob qho tib si cov nyom txias thiab sov tuaj yeem tsim tau, tab sis ob qho tib si muaj lawv qhov tsis zoo. Qhov no tsuas yog ib qho tseem ceeb xwb, tsis yog txoj cai ruaj khov. Qhov tseeb, nrog rau kev txhim kho sai ntawm kev siv tshuab yug tsiaj niaj hnub no, ntau hom muaj cov yam ntxwv zoo heev. Ntau cov nyom txiascov nyom nyommuaj kev tiv taus dej qhuav thiab cua sov zoo, yog li nws yog ib txwm pom cov nyom uas loj hlob zoo, ntom, thiab muaj yeeb yuj rau lub caij txias hauv sab qab teb. Yog tias koj tsis nyiam cov nyom uas muaj ib xim, ces ntxiv qee cov paj strawberry clover, paj clover dawb lossis ib lossis ntau cov paj ntoo qus, lawv cov paj zoo nkauj yuav ua rau koj cov nyom zoo nkauj dua.

II. Kev npaj ntawm lub txaj nyom ua ntej kev tsim kho
1. Kev ntxuav qhov chaw Tshem cov xuab zeb thiab lwm yam khib nyiab ntawm cov av (ntau tshaj 30 cm) kom tau ib lub txaj nyom uas xoob, ua pa tau, tiaj tus, thiab ntws dej zoo uas haum rau kev loj hlob ntawm cov nyom nyom. Yog tias muaj cov seem thiab cov hauv paus hauv av ntawm cov nroj tsuag ntoo, lawv yuav tsum tau tshem tawm. Txhawm rau tiv thaiv cov hauv paus seem kom tsis txhob lwj thiab ua rau muaj kev nyuaj siab.

2. Kev Tshem Tawm Cov Nroj Tsuag Yuav kom tsim tau ib lub vaj zoo, qhov teeb meem ntawm kev kis kab mob ntawm cov nroj tsuag yuav tsum tau daws. Txwv tsis pub, cov nyom txhua xyoo lossis cov nyom perennial, sedges, thiab cov nroj tsuag legume thiab convolvulaceae tuaj yeem noj cov nyom zoo hauv ib lossis ob xyoos. Cov kev tiv thaiv thiab tswj tseem ceeb: kev tshem cov nyom (suav nrog kev txiav cov nyom tas li, kev tshem cov nyom tes, thiab kev ua liaj ua teb ua ntej kev tsim vaj) thiab kev tshem cov nyom tshuaj tua kab thiab kev tua kab hauv av. Cov tshuaj tua kab hauv vaj feem ntau siv suav nrog cov tshuaj tua kab xaiv (2,4-D butyl, 2-methyltetrachloride, dicamba) thiab cov tshuaj tua kab tsis xaiv (glyphosate, paraquat). Kev tua kab hauv av tuaj yeem tua cov as-ham ntawm cov nroj tsuag thiab cov kab tsuag hauv av. Cov tshuaj tua kab feem ntau siv suav nrog methyl bromide, chloropicrin, dazomethane, thiab lwm yam, thiab kev nyab xeeb yuav tsum tau them sai sai thaum siv lawv.

3. Kho cov av pH tus nqi. Feem ntau hais lus, cov av uas muaj pH tus nqi ntawm 6-7 yog qhov tsim nyog rau feem ntau cov nyom nyom. Nws yog ib qho tsim nyog los kho qhov pH tus nqi (pH tus nqi) ntawm cov av uas muaj kua qaub ntau dhau lossis ntau dhau alkaline. Cov kev ntsuas kho yog raws li nram no: xaiv cov nyom nyom uas tiv taus kua qaub lossis alkali thiab ntxiv cov hlau lead sulfate kom txo qhov pH tus nqi; ntxiv cov txiv qaub ntsuab lossis superphosphate kom nce qhov pH tus nqi.

4. Kev Siv Tshuaj Chiv. Yuav tsum muab ib co tshuaj chiv organic ntxiv rau hauv cov av uas tsis zoo kom av zoo dua thiab xyuas kom cov nyom nyom loj hlob zoo li qub. Cov chiv av, chiv av, thiab peat yog cov tshuaj chiv organic zoo. Raws li qhov xwm txheej ntawm koj qhov chaw nyob, cov quav tib neeg, chiv av ntsuab, av nplooj, thiab lwm yam tshuaj chiv organic lossis N, P, K kuj siv tau ua cov tshuaj chiv av.

5. Kev ua liaj ua teb thiab kev sib npaug Lojkev tsim kho vajFeem ntau yog siv tshuab loj ua haujlwm. Cov nyom me me yog siv tes ua nrog hoes, rakes, thiab spiked rakes. Raws li qhov xav tau ntawm thaj av, nws raug ua kom tiaj tus mus rau hauv ib daim duab ntuj. Lub tshav pob ncaws pob yuav tsum tau tsa hauv nruab nrab kom yooj yim rau kev ntws dej los ntawm nruab nrab mus rau thaj chaw ib puag ncig.

6. Tsim ib lub tshuab dej thiab dej ntws. Feem ntau qhov chaw teeb tsa ntawm lub tshuab dej thiab dej ntws yog "ua kom yooj yim" vim yog cov laj thawj ntawm tus nqi. Qhov tseeb, ib lub nyom zoo, tshwj xeeb tshaj yog lub nyom ua si nawv, xws li chaw ua si golf thiab lub nyom ua si football, yog ib qho tseem ceeb hauv kev tsim lub nyom.
