Ukungunda okungwevu kwetumata kwenzeka ikakhulu kumanqanaba okudubula kweentyatyambo kunye neziqhamo, kwaye kungonakalisa iintyatyambo, iziqhamo, amagqabi kunye neziqu. Ixesha leentyatyambo yincopho yosulelo. Esi sifo singenzeka ukususela ekuqaleni kweentyantyambo ukuya kwindawo yeziqhamo. Umonakalo mkhulu kwiminyaka kunye nobushushu obuphantsi kunye nemozulu yemvula eqhubekayo.
Ukungunda okungwevu kwetumato kwenzeka kwangethuba, kuhlala ixesha elide, kwaye ikakhulu kuwonakalisa iziqhamo, ngoko kubangela ilahleko enkulu.
1,Iimpawu
Iziqu, amaqabunga, iintyatyambo kunye neziqhamo zinokuba yingozi, kodwa eyona nto iyingozi kwisiqhamo, ngokuqhelekileyo isifo sesiqhamo esiluhlaza sibi kakhulu.
Isifo samagqabi sikholisa ukuqala ukusuka kwincam yegqabi kwaye sinwenwele ngaphakathi ecaleni kwemithambo yesebe ngendlela “V”.
Ekuqaleni, inkcenkceshelwa, kwaye emva kophuhliso, i-tyheli-brown, kunye neencam ezingaqhelekanga kunye neempawu ezitshintshayo ezimnyama kunye nezikhanyayo.
Umda phakathi kwezicubu ezigulayo kunye nezinempilo ziyabonakala, kwaye inani elincinci le-grey kunye ne-white mold iveliswa phezu komhlaba.
Xa isiqu sinesifo, siqala njengendawo encinci efakwe emanzini, kwaye emva koko ikhule ibe yi-oblong okanye i-regular shape, i-brown light. Xa ukufuma kuphezulu, kukho umaleko wokungunda ongwevu kumphezulu webala, kwaye kwiimeko ezimandundu, isiqu kunye namagqabi angaphezulu kwenxalenye yesifo ayafa.
Isifo seziqhamo, ibala elishiyekileyo okanye amagqabi aqala osuleleka, aze anwenwele kwisiqhamo okanye kwisikhondo, oko kukhokelela ekubeni ixolo libe ngwevu, kwaye kukho umaleko ongqindilili ongwevu wokungunda, njengokubola kwamanzi.
indlela yokulawula
Ulawulo lwezolimo
- Ulawulo lwendalo
Ukungena komoya ngexesha ekuseni ngeentsuku ezinelanga, ngakumbi kwi-greenhouse yelanga kunye nokunkcenkceshela kwamanzi, iintsuku ezimbini ukuya kweyesithathu emva kokunkcenkceshela, vula i-tuyere imizuzu eyi-15 emva kokuvula umkhusane kusasa, uze uvale i-vent. Xa iqondo lokushisa kwi-solar greenhouse liphakama ukuya kuma-30 ° C, uze uvule ngokukhawuleza i-tuyere. Ubushushu obuphezulu obungaphezulu kwe 31℃ bunokwehlisa izinga lokuntshula kwembewu kwaye bunciphise ukwenzeka kwezifo. Emini, iqondo lokushisa kwi-greenhouse yelanga ligcinwa kwi-20 ~ 25 ° C, kwaye i-vent ivaliwe xa ubushushu behla ukuya kwi-20 ° C emva kwemini. Ubushushu basebusuku bugcinwa kwi-15 ~ 17℃. Ngeentsuku ezinamafu, ngokwemozulu kunye nendawo yokulima, umoya kufuneka ukhululwe ngokufanelekileyo ukunciphisa ukufuma.
- Ukulinywa kulawulo lwezifo
Ukukhuthaza ukulinywa kwefilimu encinci kunye nephezulu ye-cardigan mulching, qhuba iteknoloji yokunkcenkceshela, ukunciphisa ukufuma kunye nokunciphisa izifo. Ukunkcenkceshela kufuneka kuqhutywe kusasa ngeentsuku ezinelanga ukukhusela ukugqithisa. Ukunkcenkceshela okuphakathi ekuqaleni kwesi sifo. Emva kokunkcenkceshela, nikela ingqalelo ekukhupheni umoya kunye nokususa ukufuma. Emva kwesi sifo, susa isiqhamo esigulayo kunye namaqabunga ngexesha kwaye ujongane ngokufanelekileyo nabo ukukhusela ukusasazeka kweentsholongwane. Emva kokuqokelelwa kweziqhamo naphambi kokutyala izithole, intsalela yesifo iyasuswa ukucoca intsimi nokunciphisa ukosuleleka kweebhaktheriya.
- Ulawulo lomzimba
Ukusetyenziswa kwehlobo kunye nobushushu obuphezulu ekwindla, ivaliwe i-greenhouse yelanga ngaphezu kweveki, ukusetyenziswa kokukhanya kwelanga ukwenza iqondo lokushisa kwi-greenhouse liphakame ngaphezu kwe-70 ° C, i-disinfection ephezulu yokushisa.
Ulawulo lwekhemikhali
Ngokweempawu zegrey mold ye-tomato, kuyimfuneko ukukhetha iintlobo ezifanelekileyo zeyeza ukuze zilawule ngokwesayensi. Xa itumata ifakwe kwiintyatyambo, kwidiphu elungisiweyo yentyatyambo, i-50% yomthamo we-saprophyticus wettable powder, okanye i-50% ye-doxycarb powder emanzi, njl., yongezwa ukukhusela usulelo lwebhaktheriya. Ngaphambi kokutyala, itumato kufuneka ihlanjululwe ngokucokisekileyo nge-50% ye-carbendazim engumgubo omanzi amaxesha angama-500 ulwelo, okanye i-50% ye-Suacrine emanzi yomgubo amaxesha angama-500 ulwelo lokutshiza kanye ukunciphisa inani lebhaktheriya ye-pathogenic. Ekuqaleni kwesi sifo, amaxesha angama-2000 ulwelo lwe-50% ye-Suk eguquguqukayo engumgubo omanzi, amaxesha angama-500 ulwelo we-50% umgubo omanzi we-carbendazam, okanye amaxesha angama-1500 ulwelo lwe-50% ye-puhain emanzi yayisetyenziselwa ukuthintela kunye nokulawula isitshizi, kanye rhoqo nge-7 ukuya. Iintsuku ezili-10, kangangezihlandlo ezi-2 ukuya kwezi-3 ezilandelelanayo. Ungaphinda ukhethe 45% Chlorothalonil agent umsi okanye 10% Sukline agent umsi, 250 grams per mu greenhouse, greenhouse evaliweyo emva 7 ukuya 8 iindawo ngokuhlwa ukukhanya uthintelo umsi. Xa isifo sinzima, emva kokususa amaqabunga agulayo, iziqhamo kunye neziqu, ii-agent ezingentla kunye neendlela zithathwa ukuba zithintele kwaye zinyange amaxesha ama-2 ukuya kwe-3.
