飛夢 全自動積(ji)溫(wen)(wen)(wen)儀是(shi)我公司為農業生(sheng)產和農業科(ke)學(xue)研(yan)究新(xin)研(yan)發(fa)設(she)計的(de)(de)產品，氣溫(wen)(wen)(wen)日變化(hua)對(dui)(dui)作物(wu)生(sheng)長(chang)(chang)發(fa)育(yu)有(you)(you)很大(da)影響(xiang)。在(zai)日溫(wen)(wen)(wen)周期的(de)(de)有(you)(you)效(xiao)范(fan)圍(wei)內，即(ji)日低溫(wen)(wen)(wen)度(du)(du)不(bu)低于(yu)下限(xian)(xian)溫(wen)(wen)(wen)度(du)(du)，同時(shi)日高(gao)溫(wen)(wen)(wen)度(du)(du)也不(bu)超過上(shang)限(xian)(xian)溫(wen)(wen)(wen)度(du)(du)，這時(shi)生(sheng)長(chang)(chang)發(fa)育(yu)速度(du)(du)在(zai)適溫(wen)(wen)(wen)度(du)(du)以(yi)下隨溫(wen)(wen)(wen)度(du)(du)升高(gao)而(er)(er)加快，而(er)(er)在(zai)適溫(wen)(wen)(wen)度(du)(du)以(yi)上(shang)則(ze)隨溫(wen)(wen)(wen)度(du)(du)升高(gao)而(er)(er)減慢(man)，超過有(you)(you)效(xiao)溫(wen)(wen)(wen)度(du)(du)范(fan)圍(wei)不(bu)但將成為無效(xiao)溫(wen)(wen)(wen)度(du)(du)，甚(shen)至會對(dui)(dui)作物(wu)產生(sheng)危害，在(zai)靠近下限(xian)(xian)溫(wen)(wen)(wen)度(du)(du)或上(shang)限(xian)(xian)溫(wen)(wen)(wen)度(du)(du)時(shi)，溫(wen)(wen)(wen)度(du)(du)的(de)(de)日較差大(da)對(dui)(dui)生(sheng)長(chang)(chang)發(fa)育(yu)往(wang)往(wang)不(bu)利

全自動積溫(wen)(wen)(wen)(wen)儀是我(wo)公(gong)司為農業生(sheng)產和(he)農業科(ke)學研(yan)究新研(yan)發設計的產品(pin)，氣溫(wen)(wen)(wen)(wen)日(ri)(ri)變化對(dui)(dui)作(zuo)物(wu)生(sheng)長發育有很大影響。在日(ri)(ri)溫(wen)(wen)(wen)(wen)周期(qi)的有效范圍(wei)內，即日(ri)(ri)低(di)溫(wen)(wen)(wen)(wen)度(du)(du)(du)不(bu)(bu)低(di)于下(xia)限溫(wen)(wen)(wen)(wen)度(du)(du)(du)，同時日(ri)(ri)高溫(wen)(wen)(wen)(wen)度(du)(du)(du)也不(bu)(bu)超(chao)過(guo)上限溫(wen)(wen)(wen)(wen)度(du)(du)(du)，這時生(sheng)長發育速度(du)(du)(du)在適溫(wen)(wen)(wen)(wen)度(du)(du)(du)以下(xia)隨溫(wen)(wen)(wen)(wen)度(du)(du)(du)升高而(er)(er)加快，而(er)(er)在適溫(wen)(wen)(wen)(wen)度(du)(du)(du)以上則(ze)隨溫(wen)(wen)(wen)(wen)度(du)(du)(du)升高而(er)(er)減(jian)慢，超(chao)過(guo)有效溫(wen)(wen)(wen)(wen)度(du)(du)(du)范圍(wei)不(bu)(bu)但將成為無效溫(wen)(wen)(wen)(wen)度(du)(du)(du)，甚至會對(dui)(dui)作(zuo)物(wu)產生(sheng)危害，在靠近下(xia)限溫(wen)(wen)(wen)(wen)度(du)(du)(du)或上限溫(wen)(wen)(wen)(wen)度(du)(du)(du)時，溫(wen)(wen)(wen)(wen)度(du)(du)(du)的日(ri)(ri)較差大對(dui)(dui)生(sheng)長發育往往不(bu)(bu)利

全自動(dong)積溫(wen)(wen)(wen)(wen)儀是我公司為(wei)農(nong)業生(sheng)產(chan)(chan)和農(nong)業科(ke)學研究新(xin)研發設(she)計的(de)產(chan)(chan)品，氣(qi)溫(wen)(wen)(wen)(wen)日(ri)變化對(dui)作物生(sheng)長發育有(you)很大影響。在(zai)日(ri)溫(wen)(wen)(wen)(wen)周期的(de)有(you)效(xiao)范(fan)圍(wei)內，即日(ri)低溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)不低于下限(xian)溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)，同時日(ri)高溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)也不超過(guo)上(shang)限(xian)溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)，這時生(sheng)長發育速度(du)(du)(du)(du)在(zai)適溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)以下隨溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)升高而(er)加快，而(er)在(zai)適溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)以上(shang)則隨溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)升高而(er)減慢，超過(guo)有(you)效(xiao)溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)范(fan)圍(wei)不但將成為(wei)無效(xiao)溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)，甚至會對(dui)作物產(chan)(chan)生(sheng)危害，在(zai)靠近下限(xian)溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)或上(shang)限(xian)溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)時，溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)的(de)日(ri)較差大對(dui)生(sheng)長發育往(wang)往(wang)不利。
