Lub hauv paus system plays lub luag hauj lwm tseem ceeb heev rau tej tsob ntoo. Nws tsis tsuas yog nws nyob rau hauv ib txoj hauj lwm feem ntsug, tab sis tseem paub txog kev khiav dej thiab cov zaub mov tsim nyog rau qhov tseem ceeb ntawm txhua tus nroj tsuag.
Yuav kom ua tiav kev kho mob rau lub vaj lub vaj (dej, loosening, fertilizing ), koj yuav tsum paub raws nraim qhov twg nws muaj kab rov tav keeb kwm.
Yuav ua li cas ua lub keeb kwm ntawm Kua ntoo loj hlob?
Lub hauv paus system ntawm lub kua-ntoo yog raug xa mus rau raws li cov plaub tsiaj. Nws tau loj hlob rau ntau xyoo, nres nws txoj kev loj hlob thaum lub sij hawm ntawm cov ntoo hloov.
Muaj cov kab rov tav (ua tsaug rau lawv, cua thiab cov as-ham rau cov ntoo) thiab ntsug (lawv ntxiv dag zog rau cov ntoo hauv cov av thiab nqa dej thiab cov zaub mov los ntawm tob hauv cov khaubncaws sab nraud povtseg). Qhov tob ntawm tshwm sim ntawm feem ntsug keeb kwm nyob ntawm thaj av qhov twg tsob ntoo hlob, thiab nyob rau ntau yam. Yog li, nyob rau hauv lub tsob ntoo Siberian, lub hauv paus system lies nyob rau hauv ib qhov tob ntiav, nyob rau hauv Suav thiab hav zoov ntau - nyob rau hauv tob txheej ntawm av.
Tsis tas li ntawd, hauv paus system ntawm lub tsob ntoo kua muaj ib tug ntau tshaj tawm: nws yog skeletal thiab overgrown (friable) keeb kwm. Thawj sawv cev ntawm lub ntsiab, lub keeb kwm ntawm tsob ntoo loj, thiab ob - qhov me thiab nyias, lawv loj dua. Kev khiav dej num ntawm cov keeb kwm uas muaj kev loj tshaj plaws - ntxais hauv cov dej thiab pob zeb ua kua ntsev, zoo li tso tawm rau hauv cheeb tsam khoom ntawm cov hniav lwj. Qhov no hom ntawm keeb kwm yog nyob rau hauv lub qaum av txheej (txog li 50 cm) nyob rau hauv lub crown projection. Yog li ntawd, nws yog nyob rau hauv qhov chaw no tias daim ntawv thov ntawm chiv yuav muaj ib qho kev tshwm sim.
Raws li rau qhov ntev ntawm lub keeb kwm ntawm lub tsob ntoo kua, nws nce xyoo los ntawm lub xyoo. Thaum transplanting seedlings nyob rau hauv ib tug schoolchild, thiab tom qab ntawd rau ib tug mus tas li rau ntawm, lub keeb kwm yog traumatized, thiab lawv txoj kev loj hlob yog ib ntus tshem tawm. Tsim tawm ntawm hauv paus pob txha tseem mus txog 20 xyoo, ces tsob ntoo tsuas nce qhov ntev thiab thickness ntawm cov hauv paus hniav.
Nws kuj yuav tsum tau sau tseg lub rhiab heev ntawm kua keeb kwm kom tsawg kub (feem ntau ntau, tsuas yog Siberian, raug kev txom nyem twb nyob rau--20 ° C). Muaj kuj yog ib qho kev sib raug zoo ntawm cov hauv paus hniav thiab ntoo: txhua yam kev puas tsuaj rau lub bark ntawm lub tsob ntoo kua qaub nws lub hauv paus system.
