Kev soj ntsuam ntawm kev siv cov pa roj carbon dioxide detector
Qhov cuam tshuam ntawm kev siv cov pa roj carbon dioxide rau zaub yield
Raws li Tuam Tshoj Agricultural Information Network, dib, lws suav, thiab zucchini yog peb hom zaub. Hauv kev teb rau qhov xwm txheej no, kev sim tshuaj carbon dioxide fertilization tau ua rau ntawm peb cov zaub no, thiab cov txiaj ntsig nce ntxiv yog qhov tseem ceeb heev. Kev siv cov pa roj carbon dioxide concentration ntawm 1000 mg / kg rau peb hom zaub ua rau qhov nruab nrab nce ntawm 465.5 kg lossis 27.1% tawm los ntawm 667 square metres ntawm dib; Txiv lws suav tawm los ntawm qhov nruab nrab ntawm 410.7 kilograms ib 667 square metres, nce ntawm 23.6%; Qhov nruab nrab cov qoob loo ntawm zucchini tau nce los ntawm 373.2 kilograms ib 667 square meters, nrog nce ntawm 21.9%.
2. Cov txiaj ntsig ntawm kev siv cov pa roj carbon dioxide rau ntawm cov nroj tsuag zaub
Tom qab siv cov pa roj carbon dioxide rau cov zaub hauv cov tsev cog khoom yas, cov nroj tsuag muaj txiaj ntsig zoo dua li cov uas tsis siv. Tom qab siv cov pa roj carbon dioxide rau dib, cov nroj tsuag loj hlob zoo, nrog qhov siab nce ntawm {{0}} centimeters piv rau cov tsis siv. Cov nroj tsuag muaj 2-3 nplooj ntxiv, thiab nplooj tau loj dua thiab tuab dua. Cov nplooj ntoo ib tsob ntoo tau nce los ntawm 0.19-0.3 square meters, thiab cov txiv hmab txiv ntoo teem tus nqi siab. Cov nroj tsuag muaj 3-5 txiv hmab txiv ntoo ntau dua rau ib tsob nroj, thiab cov txiv hmab txiv ntoo nrog daim ntawv thov yog ntsuab ntsuab, thaum cov tsis muaj daim ntawv thov muaj 4-5 centimeters ntawm daj rau saum. Ntxiv mus, daim ntawv thov ntawm carbon dioxide gas fertilizer tuaj yeem txhim kho qhov txias thiab kab mob ntawm cov nroj tsuag. Tom qab siv cov pa roj carbon dioxide rau txiv lws suav, cov nroj tsuag tau nce siab hauv qhov siab, cov nplooj tig daj thiab ntsuab, cov txiv hmab txiv ntoo matured ua ntej, thiab saum npoo ntawm cov txiv hmab txiv ntoo ua ci. Cov nroj tsuag ntawm zucchini kho nrog cov pa roj carbon dioxide qhia tshwj xeeb tshaj yog cov kev hloov pauv hauv cov tsos piv rau cov tsis kho, nrog cov nplooj loj, cov nplooj tuab, thiab cov nroj tsuag loj thiab muaj zog, thaum cov tsis kho yog me thiab tsis muaj zog. Thiab qhov kev ua tau zoo ntawm daim ntawv thov yog ntxov.
3. Chaw tsim tshuaj paus ntawm lub zog txuag thiab ib puag ncig tus phooj ywg cov khoom:
Noj cov chaw tsim hluav taws xob txuag lub qhov rooj thiab qhov rais ua piv txwv: Niaj hnub no, muaj ntau lub zog txuag lub qhov rooj thiab qhov rais uas tuaj yeem ua cua tsis tau qhib qhov rais. Txhawm rau ua pov thawj lub zog ua haujlwm thiab qhov cua ntawm cov khoom, cov chaw tsim khoom muab cov neeg siv khoom siv cov pa roj carbon dioxide thiab ntsuas kub tom qab txhim kho lub zog txuag lub qhov rooj thiab qhov rais, kom cov neeg siv khoom tuaj yeem ntsuas cov pa roj carbon dioxide hauv tsev txhua lub sijhawm. Lub tshuab no tseem tuaj yeem saib xyuas qhov kub thiab txias ntawm qhov cua nyob rau tib lub sijhawm. Nrog rau cov ntaub ntawv no uas tuaj yeem soj ntsuam kev tshawb fawb txhua lub sijhawm, cov neeg siv khoom no xav tau yooj yim dua tom qab siv lub zog txuag lub qhov rooj thiab qhov rais
4. Kindergartens, chaw ua haujlwm, tsev kawm ntawv, tsev loj:
Piv txwv li, hauv chav tsev kawm ntawv, tej zaum yuav muaj kaum ob lossis ntau pua tus tub ntxhais kawm. Yog tias lub qhov rais tsis qhib rau lub sijhawm ntev, qhov concentration ntawm cov pa roj carbon dioxide yuav nce ntxiv, uas tuaj yeem ua rau kiv taub hau lossis tsaug zog ntawm cov kws qhia ntawv thiab cov tub ntxhais kawm, thiab txo qis kev kawm. Yog tias muaj cov pa roj carbon dioxide saib hauv txhua chav kawm thiab lub tshuab tau teeb tsa rau qhov tsim nyog lub tswb, yog tias lub tswb nrov tshwm sim, lub qhov rais tuaj yeem qhib los pauv cov huab cua ntshiab, uas tuaj yeem ua kom huab cua zoo thiab muab cov tub ntxhais kawm ntawv nrog ib qho ib puag ncig kev kawm ntsiag to uas tsis cuam tshuam los ntawm kev cuam tshuam sab nraud.
