Az mugja inkishof yoftani navda

Mugja navdai holo inkishofnayoftai janini meboshad. Az mugja inkishof yoftani navdaro, khususan bahoron, hangomi ba kushodashavi shuru kardani mugjaho mushohida kardan mumkin ast. YO in ki shokhchaero dar ob guzoshta dar sharoiti khona yo maktab kushodashavii mugjahoro mushohida kardan qulay ast.

Mo mebinem, ki baroi kushodashavii mugjaho fursati muayyani vaqt va sharoiti muvofiq lozim ast. To purra kushodashavii mugjaho bazan haftaho lozim meshavad.

Pesh az hama mugjaho varam karda kalon meshavand. Sipas, pulak- chahoi on boz shuda, bargchahoi pechkhurdai sabzi navda namudor meshavand. Masofai bayni bargho (baynibandho) vobasta ba surati sabzishi onho meafzoyad. Navda ba darozi qad mekashad. Tadrijan bargkho to andozai muqarrariashon, ki ba in rastani (dar tajriba istifoda shudaast) khos ast, mesabzand.

Mugjai dar nugi navda joygirshudaro sarmugja meguyand. Dar on jo konusi (yo nuqtai) sabzish faoliyat dorad. Dar natijai taqsim shudani khujayrahoi on hujayrahoi nav hosil meshavand. Konusi sabzish asosan az boftai bavujudoranda (yo hosilkunanda) iborat ast. Barghoi ibtidoii konusi sabzish mesabzand va dar natijai chunin faoliyati on (konusi sabzish) navda inkishof meyobad. Hamin tavr, az sarmugja poyai asosi va az mugjahoi pahlui navdavu shokhahoi pahlui sabzida mebaroyand. Az mugjahoi gulovar iav- dahoi gulgunchador (iavdagulho) inkishof meyoband.

Dar bisyor rastaniho sabRastanihoi alafi niz mugja dorand. Masalan, az mugjahoi boloii navniholi lubiyo yo digar rastanihoi dupalla navdai asosi sabzida mebaroyad. Az mugchahoi pahlui, ki dar poyai asosi joygirand, navdaho yo shokhchahoi pahlui inkishof meyoband.

Az nugash qad kashidani poyaro ba nazari etibor girifta, metavon sabzishu inkishofi rastanihoro idora kard. Agar nugi navdai bodiring, pomidor, pakhta, seb va digar rastanihoi dupallagiro burem, navda digar ba bolo kad namekashad. Ammo dar in rastanikho navdahoi pahlui paydo meshavand. Dar holati buridani nugi navdai pahlui boshad, vay ham az qad kashidan boz monda, sershokha meshavad.zishi bandi dida meshavad, ki dar natijai on baynibandhoi navda bosurat mesabzand va boisi qad kashidani navda (yo poya) megar- dand. Masalan, dar gandum, khayzuron (bambuk) va digar rastanihoi khushador dar natijai taqsimshavi va rushdi hujayrahoi bekhi bandi sabzishi bandi ba amal meoyad. Bo in sabab poyai navrasi baze ras- taniho bo surati kalon mesabzand. Masalan, poyai khayzuron dar davomi yak shabonaruz ziyoda az yak metr qad kashida, daroz meshavad.
