Hasharotlar yetishmasligi tufayli tabiiy chang o'tkazish jarayonlari buzilganda, qo'lda changlatish zarur qishloq xo'jaligi chorasiga aylanadi. Bu usul bog'bonlarga issiqxonalarda yoki noqulay ob-havo sharoitida yetishtirilgan ekinlarda meva hosilini kafolatlash imkonini beradi. Gullarni o'g'itlash mexanizmini tushunish qurg'oqchilikning oldini olishga va hosildorlikni sezilarli darajada oshirishga yordam beradi. Jarayon murakkab uskunalarni talab qilmaydi va bog'da muntazam mashq qilish bilan osongina o'zlashtiriladi.<\/p>\n

\"O'simliklarni<\/p>\n

Changlatish jarayonining mexanizmi<\/h2>\n

Changlatish - bu gulning erkak a'zolaridan urg'ochi a'zolariga gul changining o'tishi bo'lib, u urug' hosil bo'lish va keyingi meva rivojlanishi jarayonini boshlaydi. Ushbu biologik bosqichsiz tuxumdon rivojlanmaydi va o'simlik gulni to'kadi. Tabiatda bu jarayon yopishqoq gul chang zarralarini tashiydigan asalarilar, arilar va shamol tomonidan amalga oshiriladi.<\/p>\n

Changlatuvchi hasharotlar kam bo'lganda yoki atrof-muhit sharoitlari noqulay bo'lganda, tabiiy o'g'itlash samaradorligi pasayadi. Bog'bonlar hosilni saqlab qolish uchun ko'payish sikliga aralashishga majbur bo'ladilar. Gullarning sog'lig'ini muntazam ravishda kuzatib borish muammolarni erta aniqlash va tuxumdonlar shakllanishini rag'batlantirish uchun qo'lda usullardan foydalanish imkonini beradi.<\/p>\n

Bu jarayondagi xatolar ko'pincha o'simlik sog'lom ko'rinsa va mo'l-ko'l gullasa ham, mevalarning to'liq yo'qligiga olib keladi. Shuni yodda tutish kerakki, qo'lda changlatish bilan ham muvaffaqiyat tuproqning umumiy holati va yorug'lik darajasiga bog'liq. Ko'pgina sabzavot ekinlari uchun optimal pH qiymati 6,0\u20137,0 ni tashkil qiladi va normal meva pishishi uchun harorat oralig'i 18\u00b0C dan 25\u00b0C gacha.<\/p>\n

O'z-o'zini changlatuvchi ekinlar bilan ishlash usullari<\/h2>\n

Pomidor, qalampir va baqlajonlar germafroditlar bo'lib, ya'ni erkak va urg'ochi qismlar bitta gul ichida joylashgan. Ochiq yerda ularning changlanishi shamol tomonidan osonlashadi, ammo issiqxonalarda yoki yuqori namlikda chang og'irlashadi va to'kilmaydi. Bu gul to'plamlarini mexanik ravishda boshqarishni talab qiladi.<\/p>\n

Eng oson usul - namlik eng past bo'lgan ertalab o'simlikni muloyimlik bilan silkitish. Tebranish hasharotlarning uchishini taqlid qiladi va changning stigma ustiga tushishini rag'batlantiradi. Buning uchun eng yaxshi vaqt soat 9 dan 11 gacha, chang eng harakatchan bo'lgan vaqt.<\/p>\n

Agar chayqash natija bermasa, yumshoq cho'tka yoki elektr tish cho'tkasidan foydalaning. Cho'tkaning tebranishini gul poyasiga bir necha soniya qo'llash gul ichidagi changni samarali ravishda chiqarib yuboradi. Nozik gulbarglarga zarar yetkazmang, chunki bu mikrotravma joylarida qo'ziqorin infektsiyalariga olib kelishi mumkin.<\/p>\n

\"Pomidorlarni<\/p>\n

Qovoq ekinlari bilan ishlash<\/h2>\n

Bodring, qovoq, qovoq va qovunlarning alohida gullari bor, bu esa urug'lantirishni murakkablashtiradi. Erkak gullari odatda oldinroq paydo bo'ladi va tuxumdonlari bo'lmaydi, urg'ochi gullar esa tagida kichik meva borligidan osongina aniqlanadi. O'zaro changlatish uchun erkak guldan urg'ochi gulga changni qo'lda o'tkazish kerak.<\/p>\n

Ushbu protsedurani bajarish uchun erkak guldan barglarni ehtiyotkorlik bilan olib tashlang, shunda changlatgichlar paydo bo'ladi. Changni yig'ish uchun yumshoq cho'tkadan foydalaning yoki shunchaki erkak gulni urg'ochi gulning stigmasiga qo'ying. Agar ehtiyotkorlik va ehtiyotkorlik bilan bajarilsa, bitta erkak gul bir nechta urg'ochi gullarni changlatish uchun yetarli.<\/p>\n

Gullarning ochilish vaqtini kuzatib borish muhimdir, chunki ular qisqa umr ko'radi, ko'pincha faqat bir kun davom etadi. Agar ob-havo bulutli bo'lsa, jarayon kechikishi mumkin, ammo changlatish samaradorligi pasayadi. 25\u00b0C dan yuqori tungi haroratlarda gulchang ko'pincha steril bo'lib qoladi, shuning uchun hatto samarali qo'lda changlatish ham muvaffaqiyatsiz bo'lishi mumkin.<\/p>\n

Makkajo'xori changlatishining xususiyatlari<\/h2>\n

Makkajo'xori asosan shamol orqali changlanadi, shuning uchun to'g'ri blok ekish muvaffaqiyat uchun juda muhimdir. Erkak gullar (panicles) o'simlikning yuqori qismida, urg'ochi gullar (stigmalar) esa barg qo'ltiqlarida joylashgan. Stigmaning har bir tolasi boshoqda to'liq don hosil qilish uchun chang olishi kerak.<\/p>\n

Shamolsiz ob-havoda gulchang stigmalardan oshib ketishi mumkin, natijada "bo'sh" quloqlar paydo bo'ladi. Buni tuzatish uchun panikulani kesib oling va uni qo'shni o'simliklarning stigmalari ustiga muloyimlik bilan silkiting. Gulchang faol ravishda ajralib chiqayotgan bir paytda, bu jarayonni har kuni bir hafta davomida takrorlang.<\/p>\n

Daraxtlarning holatini kuzatib boring: ular yangi va nam bo'lishi kerak. Agar ular gulchang chiqishidan oldin qurib qolsa, urug' hosil bo'lmaydi. Mo''tadil iqlim sharoitida, haddan tashqari issiqda gullashning oldini olish uchun ekish vaqtini to'g'ri belgilash muhimdir.<\/p>\n

Tez-tez so'raladigan savollar: Tez-tez so'raladigan savollarga javoblar<\/h2>\n

Nima uchun tuxumdonlar qo'lda changlatishdan keyin ham tushib ketadi?<\/h3>\n

Ko'pincha sabab mikroiqlim nomutanosibligi yoki ozuqaviy moddalarning yetishmasligidir. Havo yoki tuproqning haddan tashqari harorati gulchanglarning sterilligiga olib keladi, namlikning yetarli emasligi esa o'simlikni omon qolish uchun ortiqcha tuxumdonlarni tashlashga majbur qiladi. Tuproqdagi azot va kaliy miqdorini tekshiring va muntazam sug'orishni ta'minlang.<\/p>\n

Gulchangni kelajakda foydalanish uchun saqlash mumkinmi?<\/h3>\n

Ha, ba'zi ekinlardan olingan changlarni yig'ib olish va muzlatgichda havo o'tkazmaydigan idishda bir necha kun davomida saqlash mumkin. Bu bog'dagi erkak va urg'ochi gullar turli vaqtlarda ochilganda foydalidir. Biroq, yangi chang har doim eng yaxshi gul hosilini beradi.<\/p>\n

Ochiq yerdagi o'simliklarni changlatish kerakmi?<\/h3>\n

Ochiq yerda bu faqat hasharotlar g'ayritabiiy tanqisligi yoki uzoq muddatli yomg'ir paytida kerak. Agar hududda asalarilar va arilar ko'p bo'lsa, ular bu vazifani odamlarga qaraganda yaxshiroq bajaradilar. Istisno - bu ular yetishmaganda o'zaro changlanishni talab qiladigan ekinlardir.<\/p>","protected":false},"excerpt":{"rendered":"
