Indlela yokuphucula umgangatho weSiqhamo seWatermelon kwaye uthintele ukuhla kweSiqhamo?

Ibhetshi yokuqala yeevatala entlakohlaza ibeka isiqhamo kwangethuba, ivuthwa kwangethuba, kwaye iyalela ixabiso eliphezulu. Nangona kunjalo, imozulu yasentwasahlobo engazinzanga yenza kube nzima ukubeka iziqhamo, okukhokelela kumngcipheko omkhulu wokuhla kweziqhamo. Ukuphucula izinga lokumisela iziqhamo kunye nokuthintela ukuwa kweziqhamo yeyona nto iphambili kubalimi bevatala.

I. Yintoni iWatermelon Fruit Drop?

Ukuwa kwesiqhamo se-watermelon kubhekiselele ekumeni kokukhula kwe-ovary kwisityalo, ukuqala kwindawo ephezulu yesiqhamo esincinci ngokuthe ngcembe sijike sibe tyheli kwaye sishwabene, ekugqibeleni kukhokelele ekuweni kwesiqhamo.

II. Izinto ezibangela iWatermelon Fruit Drop:

1. Ukungaphumeleli kweentyantyambo zabasetyhini ukuba zifakwe i-pollinated kwaye zichunyiswe emva kokutyatyamba. Iivatala zizityalo ezine-monoecious ezineentyantyambo eziziinkunzi nemazi ezahlukeneyo. Ukuba ixesha leentyantyambo lihambelana nemozulu yemvula, i-pollen iya kuthatha umswakama kunye nokugqabhuka; okanye ukuba kukho izinambuzane ezimbalwa ze-pollinating, iintyatyambo zesetyhini azikwazi ukuhlanjululwa ngokufanelekileyo, ukuthintela i-ovary ukuba ikhulise kwaye ikhule ngokuqhelekileyo, ibangele ukuba iwele.

2. Ukungaqhelekanga kumalungu eentyatyambo zemazi okanye zendoda. Ngokomzekelo, ibala elifutshane kakhulu, ukungabikho kwamadlala e-nectar, ukungabikho kwemveliso ye-pollen kwi-anthers, okanye ukubola kwepistil kunokubangela ukuhla kwesiqhamo sevatala.

3. Zombini ukukhula okugqithisileyo kunye nokubuthathaka kwezityalo kunokubangela ukuwa kweziqhamo. 4. Ukufuma okungalungelelanisiyo komhlaba ngexesha leentyantyambo. Amanzi amaninzi akhokelela ekukhuleni kwezityalo ngokugqithisileyo, nto leyo ebangela ukuba iintyatyambo ezizimazi zingondleki nto leyo ekhokelela ekuphunyezweni kweziqhamo. Ukungoneli kwamanzi kubangela ukuba isityalo siwise iintyatyambo ngenxa yokungabikho kwamanzi.

5. Iimeko zokusingqongileyo ezingathandekiyo. Amaqondo obushushu aphezulu kakhulu okanye aphantsi kakhulu ngexesha leentyantyambo ayonakalisa i-pollen tube elongation, ekhokelela ekuchumeni kakubi kunye nokuwa kweentyatyambo. Ukukhanya okungonelanga kuthintela iphotosynthesis, kubangela ukuba i-ovary ihlupheke okwexeshana kukungondleki kwaye ibangele ukuphunza kweziqhamo.

6. Ukungalingani phakathi kokukhula kwezityalo kunye nokuzala. Ukukhula okugqithisileyo kwezityalo kunokukhokelela ekukhuleni kakubi kweentyatyambo zasetyhini kunye nokuphunza kweziqhamo.

7. Ukuxinana. Ukuxinana kukhokelela ekukhanyeni okulambathayo kunye nokukhula okugqithisileyo kwezityalo, okuchaphazela ukukhula kwenzala kwaye kwenza ukumiselwa kweziqhamo kube nzima.

8. Umonakalo obangelwa zizinambuzane nezifo.

III. Iindlela zokuthintela kunye nokulawula ukuphunza kweziqhamo zevatala:

1. Umvumvuzelo ongeyonyani.
1. Ngexesha leentyantyambo zevatala, khetha iintyatyambo zesilisa phakathi kwe-7 kunye ne-10 ekuseni, susa i-corolla, kwaye usebenzise ngokulinganayo i-stamens yeentyantyambo zemazi. Qaba i-stamens kwiintyatyambo ezizimazi ezi-2-3 kwintyatyambo yenkunzi nganye. Phatha ngobunono ngexesha lomvumvuzelwano ukunqanda ukonakalisa ibala.

2. Cwangcisa ixesha lokuhlwayela ngocoselelo, uqinisekise ukuba ixesha lokumisela isiqhamo sevatala liyawanqanda amaxesha onyaka emvula ukuze kube lula ukuvuthela. Ukubonelela ngeemeko ezifanelekileyo zokusingqongileyo kwizithole ngexesha lenqanaba lokugalela ukukhuthaza ukwahluka kwamathupha entyatyambo kunye nokunciphisa amathuba okuba neentyatyambo ezinobulwelwe.

3. Faka isichumiso namanzi ngokwenzululwazi.
Faka isichumiso esinzima ngaphambi kokuhlwayela, ngokuyinhloko isichumisi se-organic, esongezwa nge-nitrogen esebenza ngokukhawuleza, i-phosphorus, kunye nezichumisi ze-potassium. Nciphisa ukufakwa kwesichumiso senitrogen ngokufanelekileyo ngexesha lokukhula komdiliya kunye neentyatyambo. Landela imigaqo yokuchumisa kwaye ulawule ukunkcenkceshela ngokufanelekileyo ukuqinisekisa ukukhula okuqinileyo kwaye uthintele ukukhula okugqithisileyo kwezityalo.

4. Lawula ukukhula okugqithisileyo komdiliya ukunciphisa ukusetyenziswa kwezondlo ngokungeyomfuneko.

5. Tyala ngokuxinana okufanelekileyo ukuqinisekisa ukungena komoya kunye nokungena kokukhanya.

6. Ukuthenwa kwangexesha kunye nokuthena: Ukuthena akupheleli nje ekulinganiseni ukukhula kwezityalo nokuzala kodwa kukwaphucula umoya nokungena lula. Emva kokumiselwa kweziqhamo, ukugalela ngexesha elifanelekileyo kugxininise unikezelo lwezondlo, ukukhuthaza ukwandiswa kweziqhamo.

7. Ukusebenzisa izilawuli zokukhula kwezityalo: Ngomhla intyatyambo yasemazi ivula okanye kusuku olungaphambili, fafaza ihlumela lesiqhamo nge-0.1% Forchlorfenuron. Gcoba ngokulinganayo kumacala omabini esiqhamo. Ngokuqhelekileyo, kumaqondo obushushu angaphantsi kwe-18°C, sebenzisa malunga ne-10ml ye-0.1% ye-Forchlorfenuron exutywe kwi-1.5kg yamanzi; kwi-18-24 ° C, sebenzisa i-10ml ehlanjululwe kwi-1.5-2kg yamanzi; kunye ne-25-30 ° C, sebenzisa i-10ml ehlanjululwe kwi-1.5-3kg yamanzi. Oku kukhuthaza ukumiselwa kweziqhamo kwaye konyusa izinga lokumiselwa kweziqhamo.

8. Ukongezwa ngezinto zokulandelela kwandisa ubumnandi kunye nombala, kukhusela iintyatyambo kunye neziqhamo, kukhuthaza ukwanda kweziqhamo kunye nokukhula, kwaye kwandisa isivuno.

9. Uthintelo kwangethuba kunye nolawulo lwezinambuzane nezifo.
