Nutrient av disinfection method rau seedbed ua

Nutrient av rau seedbed npaj:

Cov kev sim tau pom tias cov av npaj tau zoo yog cov khoom noj muaj txiaj ntsig thiab muaj cov av zoo aeration. Cov av zoo yuav tsum muaj tag nrho cov porosity ntau dua 60 feem pua, qhov ntom ntom tsawg dua los yog ze rau 1, muaj cov ntsiab lus nitrogen ntawm 50-100PPm, muaj phosphorus cov ntsiab lus ntawm 15PPm, thiab muaj cov ntsiab lus poov tshuaj ntawm {{4} } PIB. Fermented, decomposed thiab sieved quav tso nyiaj rau 20 feem pua. Cov khoom siv xoob xoob yog nyiam dua sifted nees quav tom qab tau fermented thiab decomposed, thiab fermented thiab siav sawdust los yog sifted rauv tshauv kuj siv tau. Tom qab cov ntaub ntawv npaj txhij, tig dua ob peb zaug kom cov quav zoo sib xyaw. Tom qab cov as-ham tau npaj, nws tuaj yeem muab ntim rau hauv lub noob, thiab tom qab ntawd nws tuaj yeem ua kom tsis muaj menyuam.

Seedbed Preparation Bed Av Disinfection: Muaj ntau yam kab mob hauv av thiab chiv. Yog li ntawd, cov nroj tsuag theem kab mob xws li kev hloov tam sim ntawd, fusarium wilt thiab anthracnose yog nquag tshwm sim. Qee lub sij hawm nws yooj yim puas los ntawm cov kab tsuag hauv av xws li crickets, grubs, koob, thiab lwm yam, tshwj xeeb tshaj yog thaum cov yas tsev cog khoom seedbeds siv los ua cov av rau ntau xyoo ntawm cov noob tsis tu ncua, kev puas tsuaj loj heev. Txhawm rau tiv thaiv qhov tshwm sim ntawm cov kab mob no thiab kab tsuag, ntxiv rau kev hloov cov av txaj, nws tseem yuav tsum tau ua txoj haujlwm zoo hauv kev tua kab mob ntawm cov av hauv txaj thiab kev tiv thaiv thiab tswj cov kab mob thiab kab tsuag.

Muaj ntau cov fungicides siv rau cov av tua kab mob hauv cov noob qoob loo, xws li pentachloronitrobenzene, zinc Dyson, formalin, tooj liab sulfate, methyl bromide, thiab lwm yam. Cov tshuaj tua kab yog phoxim, methyl isothiocyanate, trichlorfon thiab lwm yam. Thaum siv cov fungicides, kev saib xyuas tshwj xeeb yuav tsum tau coj los tiv thaiv kev puas tsuaj rau cov noob buds thiab sprouts. Yog li ntawd, kev sim me me tau ua ua ntej kev xa tawm loj. Cov tshuaj sib txawv muaj cov txheej txheem tshuaj tua kab mob sib txawv.

Seedbed npaj ntawm pentachloronitrobenzene thiab mancozeb tshuaj tua kab mob txoj kev: txhua square meter ntawm txaj av saum npoo yog tov nrog 5 grams ntawm pentachloronitrobenzene thiab manganese zinc, thiab 12-15 kg ntawm semi-dry zoo av yog tshuaj av. Siv ua subsoil lossis npog av thaum tseb.
