Kukamurwa kwematanda akachekwa

Mapango akachekwa zvinoreva mapuranga nema slats emarudzi econiferous anosvika 100 mm, anogadzirirwa kushandiswa sese uye kugadzira zvikamu uye zvigadzirwa zvakapedzwa pakuvaka.

Mapango akachekwa akakamurwa kuita mapuranga, ayo hupamhi hunodarika kaviri ukobvu, uye machira, ayo upamhi husingapfuuri kaviri ukobvu. Ukobvu hwemapuranga matete hunokwira kusvika pa 35 mm, uye makobvu kupfuura 35 mm.

Zvinoenderana nechimiro chekugadziriswa, matanda akachekwa akakamurwa kuita akachekwa, apo ese ari maviri mativi akatetepa anochekwa pamwe nehurefu hwawo hwese kana imwe neimwe yadzo inokwana hafu yehurefu, uye isina kuchekwa, apo mativi akatetepa haana kuchekwa zvachose kana kuchekwa isingasviki hafu yehurefu. Mativi maviri akafara emapuranga akachekwa neasina kuchekwa anofanira kugadziridzwa nehurefu hwese.

Maererano nehutano hwehuni uye kushandiswa kwayo, matanda akacheka akakamurwa kuva makirasi anotevera: ** prima-extra, I, II, III, IV ** uye ** V **.

Makirasi ematanda akachekwa zvinoenderana nechinangwa

Kirasi yematanda akachekwa ezvimiro zvemapuranga anofanira kuenderana nemaitiro ekugadzira.

Sawn huni dzemhando dzeconiferous

Sawn matanda anogadzirwa kubva papine, spruce, larch, misidhari uye fir huni. Hurefu hwemapuranga akachekwa hunobva pa1ku6,5 mnekuwedzera0,25 m, uye yekuvaka ngarava nekuvaka zambuko kusvika9,5 mnekureba kwakafanana kuwedzera.

Zviyero zvemapuranga nematanda

Upamhi nekukora kwematanda akachekwa anotemerwa huni nehunyoro15%. Kana hunyoro hwakakwirira, matanda akachekwa emhando dzese dzehuni, kunze kwelarch, anofanira kunge aine kuwanda nekuda kwekuoma zvinoenderana nechiyero chazvino. Kune larch, uremu hwakawandisa nekuda kwekuoma hunowedzera30%kubva kuhukuru kubva kune zvakajairwa zvine chekuita nepine, spruce nemisidhari.

Hunyoro hwematanda akachekwa hauna kuenderana.

Matanda emhando dzeconiferous

Mapango emarudzi econiferous, ane mativi mana uye ane mativi maviri, ane ukobvu kubva 110 kusvika 240 mm. Pamatanda ane mativi mana, mativi mana ose anofanira kugadziriswa, uye pamatanda ane mativi maviri, mativi maviri chete.

Kureba kwematanda kunotarwa kubva 1 kusvika 6,5 m, nekuwedzera kwe 0,25 m, uye yekuvaka ngarava uye bhiriji rekuvaka kusvika 9,5 m nekukura kwakafanana kuwedzera. Mapango anoshandiswa kumabhiriji enjanji ane hurefu hwe 3,2; 4,2 uye 5,2 m.

Kufara nekukora kwematanda ane mativi mana kunotangira pa 110 kusvika 240 mm. Mapango emabhiriji enjanji anogadzirwa muukobvu nehupamhi 200 × 240, 220 × 260 uye 220 × 280 mm. Upamhi hwemativi akachekwa emapuranga ane mativi maviri haaenzaniswi.

Matanho ematanda akatemerwa huni dzine hunyoro hwe 15%. Kana hunyoro huchikwira, matanda emhando dzese, kunze kwelarch, anofanirwa kunge aine kuwanda nekuda kwekuoma zvinoenderana nechiyero chazvino. Kune matanda akagadzirwa nelarch huni, zviyero zvakawandisa nekuda kwekuoma kunowedzera kana zvichienzaniswa nemaitiro akatemerwa pine, spruce, misidhari uye fir. Mapango emabhiriji enjanji anogonawo kugadzirwa nemuti wemuoki.

Maererano nehutano hwehuni, matanda akakamurwa kuva makirasi mana: I, II, III uye IV. Ndeipi kirasi ichashandiswa kune zvimwe zvivakwa zveinjiniya uye zvinhu zvinotemerwa nemazinga akakodzera uye tekinoroji mamiriro ekuvaka uye zvinhu.

Kirasi I matanda anoshandiswa kumabhiriji enjanji nemichina yekurima. Mabheti ekirasi I neII haafanire kuunzwa asati achembera mumawinji kwemazuva asingasviki 30.

Sawn matanda emhando dzakaoma

Mukutaura kwehutano, huni hunofanira kusangana nezvinodiwa zvehutano. Mabhodhi, slats uye matanda akagadzirwa nemhando dzehuni dzakaoma anoshandiswa zvese uye muzvidimbu zvipfupi zvezvinhu zvakasiyana mukugadzirwa kwakasiyana kwemaindasitiri nekuvaka.

Sawn matanda inogadzirwa kubva muoki, madota, beech, birch, chub, hornbeam, elm, alder, aspen, linden, poplar, etc. Inokamurwa kuva mapuranga, apo hupamhi hunopfuura kaviri kukora, laths, hupamhi husingapfuuri kaviri kukora, uye matanda, apo zvose ukobvu uye hupamhi zvakakura kudarika.100 mm. Nekukora, matanda akachekwa anokamurwa kuita matete, kusvika35 mm, uye mukukora,35-40 mm.

Kugadzira matanda akaomarara

Zvinoenderana nechimiro chekugadzirisa, matanda akachekwa akakamurwa kuita:

• yakagadziriswa, apo mativi ose mana anogadziriswa, uye ukuru hwemativi asina kucheneswa hahuna hukuru kupfuura zviyero zvinobvumirwa;
• isina kucheneswa, uko mativi akafara akachekwa, uye akamanikana asina kucheneswa, kana uko zviyero zveasina kucheneswa akatetepa uye akafara mativi akakura kupfuura anobvumidzwa.

Zviyero uye humidity

Zviyero zvemapuranga akacheka ndezvizvi:

• kureba kwe1ku6,5 m, kuwedzera ne0,1 m;
• ukobvu7,10,13,16,19,22uye25-50 mm, kuwedzera ne5 mm,i50-130 mm, kuwedzera ne10 mm;
• upamhi hwe50 mmuye kuwedzera, kuwedzera10 mm.

Upamhi hwechinhu chisina kupera ndiyo hafu yehupamhi hwemativi maviri akafara, akayerwa pakati pehurefu hwechinhu chakapihwa, izvo zvikamu kusvika0,5 cmusaverenge, a0,5 cmuye zvakawanda zvinoverengwa se1 cm.

Zviyero zvematanda akachekwa maererano nehupamhi nehupamhi hunotarirwa kune hunyoro hwehuni15%. Kana hunyoro hwakakwirira, matanda akachekwa anofanira kunge akawandisa nekuda kwekuoma.

Hunyoro hwematanda akachekwa hahufanire kunge hwakanyanya kudarika25%abs. Maererano nezvikanganiso zvehuni, kuchena kwekugadzirisa uye chiyero chekururama, matanda akachekwa anogadzirwa mumakirasi mana: I, II, III uye IV.

Misoro inoenderana: kuvaka, huni hunyoro, kuomesa huni, michina yekuveza nemidziyo uye kugadzirwa kwemahwindo nemagonhi emapuranga
