zvigadzirwa

Basa remambure ezuva:
(1) Shading, kutonhora uye kunyorovesa Parizvino, chiyero chemumvuri wemambure emumvuri anogadzirwa munyika yangu 25% kusvika 75%.Shade mambure emavara akasiyana ane akasiyana mwenje transmittances.Semuyenzaniso, kuvheneka kwemwenje wemambure ekutema shading kwakadzikira zvakanyanya kupfuura esirivha-grey shading nets.
Nekuti iyo shading net inoderedza kusimba kwechiedza uye kupenya kupisa kwechiedza, ine inotonhorera inotonhorera maitiro, uye nepamusoro tembiricha yekunze, zvinova pachena zvakanyanya kutonhora.Kana kupisa kwekunze kwemhepo kunosvika 35-38 ° C, kutonhora kwakawanda kunogona kusvika 9-13 ° C, uye kudonha kwakanyanya kunogona kuva 19.9 ° C.Iyo inonyanya kutonhora inotonhorera iri pamusoro, inoteverwa nehupamhi hwemasendimita makumi maviri kumusoro uye pasi pevhu, uye huwandu hwemasendimita mashanu kumusoro uye pasi pemashizha emuti.Kuvhara mambure ezuva muzhizha rinopisa, tembiricha yepamusoro inogona kudzikiswa ne4-6°C, iyo yepamusoro inogona kusvika 19.9°C, tembiricha ye30cm pamusoro pevhu inogona kudzikiswa ne1°C, uye tembiricha ye5. masendimita pasi pevhu anogona kudzikiswa ne3-5 ° C;kana nzvimbo yakavharwa, tembiricha ye5cm pasi pevhu inogona kudzikiswa Deredzera ne6 kusvika 10°C.
Mushure mekunge mambure emumvuri akafukidzwa, kupisa kwezuva kunoderera, kutonhora kwepasi kunodonha, mhepo inomhanya inopera simba, uye kubuda kwevhu kunyorova.Kazhinji, evaporation inongova 30% kusvika 40% yenzvimbo yakashama, iyo ine mabasa ari pachena ekudzivirira kusanaya kwemvura uye kunyorovesa.
(2) Mhepo-inopesana nemhepo, inonaya-inonaya, inodzivirira zvirwere uye inodzivirira zvipembenene Iyo shading mambure ine simba rakakwirira remagetsi, iyo inogona kuderedza kurasikirwa kwemiriwo inokonzerwa nedutu, dutu remvura, chimvuramabwe uye mamwe mamiriro ekunze akaipa.
Iyo greenhouse yakafukidzwa nemambure ane shading.Munguva yechamupupuri, mhepo inomhanya mukati meshedhi inongova ye40% yemhepo inomhanya kunze kweshedhi, uye mhepo inovhara mhepo inooneka.

3. Kusarudzwa kwe sunshade net material
1. Shading rate: Kusarudzwa kwemumvuri net shading rate kunofanirwa kutarisisa zvizere zvinotevera zvinhu: greenhouse type, greenhouse covering material, mamiriro ekunze ekunze, uye greenhouse crops mhando.Kunyanya izvo zvinodikanwa zvemwenje zvemhando dzezvirimwa, mwenje muripo wenzvimbo uye mwenje saturation poindi yephotosynthesis yezvirimwa zvakasiyana zvakasiyana padanho rega rega rekukura.Mushure mekutarisa zvizere zvinhu zvakawanda, chiedza chakanyanya kufanira chechirimwa chinofanirwa kuenzaniswa zvakakwana uye chinodhura zvakanyanya chinofanira kusarudzwa., Inonzwisisika mumvuri mambure.
Mhando uye mabasa emambure e shading mumagreenhouses akanakira sarudzo yako yekudyara kwekurima muzhizha

Kutonhodza maitiro: Pasi pemamiriro ekuona chiedza chinodiwa pakukura kwechirimwa, kuwedzera kwemwaranzi yezuva kunoratidzwa nemambure ezuva, ndiko kunoita kuti kutonhora kuwedzere.Munguva yekutonhora kwemukati memumvuri, chikamu chechiedza chezuva chinotaridzwa neshading net pachayo, zvichikonzera kuwedzera kwekushisa kwemambure e shading uye kuchinjana kwekupisa nemhepo yemukati, nekudaro kuwedzera tembiricha yegreenhouse. .Naizvozvo, kuti uwane yakanakisa kutonhora mhedzisiro yekutonhodza kwemukati, iyo yakasarudzwa shading net inofanirwa kunge iine yakakwira reflectivity kune solar radiation.Kazhinji, iyo aluminium foil mualuminium foil mesh ine yakakwira ratidziro kune radiation yezuva, uye kutonhora kwacho kwakakwira zvakanyanya kupfuura kwemamwe marudzi emameshi.Mhedzisiro yekutonhodza yekunze kwezuva inogona kufuratira chikamu chesimba rinonyudzwa nemambure ezuva pachayo, saka kutonhora kwekunze kwezuva kunowanzo kutsanangurwa nechiyero chemumvuri.
