Ungalithuthukisa Kanjani Isilinganiso Sokusetha Isithelo Se-Watermelon Nokuvimbela Ukwehla Kwesithelo?

Iqoqo lokuqala lamakhabe entwasahlobo libeka isithelo kusenesikhathi, livuthwa kusenesikhathi, futhi libiza inani eliphezulu. Kodwa-ke, isimo sezulu sasentwasahlobo esingazinzile senza ukubeka izithelo kube nzima, okuholela engozini enkulu yokwehla kwezithelo. Ukuthuthukisa izinga lokumisa isithelo kanye nokuvimbela ukwehla kwezithelo yinto ebaluleke kakhulu kubalimi bamakhabe.

I. Yini I-Watermelon Fruit Drop?

Ukwehla kwesithelo se-Watermelon kubhekisela ekumeni kokukhula kwe-ovary esitshalweni, kuqala ngendawo engenhla yesithelo esincane kancane kancane ibe phuzi futhi ishwabe, ekugcineni kuholele ekuweni kwezithelo.

II. Izimbangela zokuwa kwesithelo se-Watermelon:

1. Ukwehluleka kwezimbali zesifazane ukuba zifakwe impova futhi zivundiswe ngemva kokuqhakaza. Amakhabe ayizitshalo ze-monoecious ezinezimbali ezihlukene zesilisa nezesifazane. Uma isikhathi sokuqhakaza sihambisana nesimo sezulu semvula, impova izomunca umswakama futhi iqhume; noma uma kunezinambuzane ezimbalwa ezithutha impova, izimbali zesifazane azikwazi ukuthululwa kahle, ukuvimbela i-ovary ukuthi ingakhuli futhi ikhule ngokujwayelekile, ibangele ukuwa.

2. Ukungajwayelekile ezithweni zezimbali zesifazane noma zesilisa. Isibonelo, ukucwaswa okufushane kakhulu, ukungabikho kwezindlala ze-nectar, ukuntuleka kokukhiqizwa kwempova kuma-anthers, noma ukuwohloka kwe-pistil konke kungabangela ukwehla kwezithelo zekhabe.

3. Kokubili ukukhula kwezitshalo ngokweqile nokubuthakathaka kungabangela ukwehla kwezithelo. 4. Umswakama womhlabathi ongalingani ngesikhathi sokuqhakaza. Amanzi amaningi aholela ekukhuleni kwemifino ngokweqile, okwenza izimbali zesifazane zingondleki futhi kubangele ukukhishwa kwezithelo. Amanzi anganele enza isitshalo siwise izimbali ngenxa yokuntuleka kwamanzi.

5. Izimo zemvelo ezingezinhle. Amazinga okushisa aphakeme kakhulu noma aphansi kakhulu ngesikhathi sokuqhakaza ayingozi ekwandiseni amashubhu empova, okuholela ekuvundiseni okungekuhle kanye nokwehla kwembali. Ukukhanya okunganele kuvimbela i-photosynthesis, okubangela ukuthi i-ovary ihlupheke okwesikhashana ngenxa yokungondleki futhi okuholela ekuphusheni kwezithelo.

6. Ukungalingani phakathi kokukhula kwezitshalo nokuzala. Ukukhula kwezitshalo ngokwedlulele kungaholela ekukhuleni okungekuhle kwezimbali zabesifazane kanye nokuhushulwa kwezithelo.

7. Ukuminyana. Ukuminyana kuholela ekukhanyeni okungekuhle kanye nokukhula kwezitshalo ngokweqile, okuthinta ukukhula kokuzala futhi kwenza ukumiswa kwezithelo kube nzima.

8. Umonakalo obangelwa izinambuzane nezifo.

III. Izindlela zokuvimbela nokulawula ukuphunza kwesithelo sekhabe:

1. Impova yokwenziwa.
1. Ngesikhathi sokuqhakaza kwekhabe, khetha izimbali zesilisa phakathi kuka-7 no-10 ekuseni, susa i-corolla, futhi usebenzise ngokulinganayo ama-stamens ezimbali zesifazane. Faka ama-stamens ezimbalini zesifazane ezi-2-3 imbali ngayinye yesilisa. Bamba ngobumnene ngesikhathi sempova ukuze ugweme ukulimaza ukucwaswa.

2. Hlela isikhathi sokuhlwanyela ngokucophelela, uqinisekise ukuthi isikhathi sokumisa isithelo sekhabe sigwema izinkathi zemvula ukuze kube lula ukuvuthwa kwempova. Nikeza izimo ezifanelekile zemvelo zezithombo ngesikhathi sesiteji sokutshala ukuze kuthuthukiswe ukuhlukaniswa kwezimbali zezimbali nokunciphisa amathuba okuba nezimbali ezikhubazekile.

3. Faka umanyolo namanzi ngokwesayensi.
Faka umanyolo osindayo wesisekelo ngaphambi kokuhlwanyela, ikakhulukazi umanyolo ophilayo, ohambisana nomanyolo osebenza ngokushesha we-nitrogen, phosphorus, kanye ne-potassium. Nciphisa ukusetshenziswa komanyolo we-nitrogen ngendlela efanele ngesikhathi sokukhula komvini nokuqhakaza. Landela izimiso zokuvundisa futhi ulawule ukuchelela ngendlela efanele ukuze uqinisekise ukukhula okuqinile futhi uvimbele ukukhula kwezitshalo ngokweqile.

4. Lawula ukukhula komvini ngokweqile ukuze unciphise ukusetshenziswa kwezakhamzimba kungenasidingo.

5. Tshala lapho kuminyene khona ukuze uqinisekise ukungena komoya kanye nokukhanya.

6. Ukuthena kanye nokuthena okufika ngesikhathi: Ukuthena akugcini nje ukulinganisa ukukhula kwezitshalo nokuzala kodwa kuthuthukisa nokungena komoya kanye nokungena kancane. Ngemuva kokumiswa kwesithelo, ukugcotshwa okufika ngesikhathi kugxilisa ukunikezwa kwezakhamzimba, okukhuthaza ukukhuliswa kwesithelo.

7. Usebenzisa izilawuli zokukhula kwezitshalo: Ngosuku izimbali zowesifazane ezivula ngalo noma ngayizolo, fafaza ihlumela lesithelo ngo-0.1% we-Forchlorfenuron. Fafaza ngokulinganayo ezinhlangothini zombili zesithelo. Ngokuvamile, emazingeni okushisa angaphansi kuka-18°C, sebenzisa cishe u-10ml ka-0.1% we-Forchlorfenuron exutshwe ku-1.5kg wamanzi; ku-18-24 ° C, sebenzisa i-10ml ehlanjululwe ku-1.5-2kg yamanzi; futhi ku-25-30 ° C, sebenzisa i-10ml ehlanjululwe emanzini angu-1.5-3kg. Lokhu kukhuthaza ukumiswa kwesithelo futhi kwandisa izinga lokumiswa kwezithelo.

8. Ukwengeza ngama-trace elements kuthuthukisa ubumnandi nombala, kuvikela izimbali nezithelo, kukhuthaza ukukhula nokukhula kwezithelo, futhi kwandisa isivuno.

9. Ukuvimbela kanye nokulawula izinambuzane nezifo ngesikhathi.
