Isikhunta esimpunga sikatamatisi sivela ikakhulukazi ezigabeni zokuqhakaza nezokuthela, futhi singalimaza izimbali, izithelo, amaqabunga neziqu. Isikhathi sokuqhakaza yinani eliphakeme lokutheleleka. Lesi sifo singenzeka kusukela ekuqaleni kokuqhakaza kuya ekubekeni izithelo. Umonakalo mkhulu eminyakeni enamazinga okushisa aphansi kanye nesimo sezulu esinezimvula esiqhubekayo.
Isikhunta esimpunga sikatamatisi sivela kusenesikhathi, sihlala isikhathi eside, futhi silimaza kakhulu isithelo, ngakho sibangela ukulahlekelwa okukhulu.
1,Izimpawu
Iziqu, amaqabunga, izimbali nezithelo kungaba yingozi, kodwa umonakalo omkhulu esithelweni, ngokuvamile isifo sezithelo eziluhlaza sibi kakhulu.
Isifo samaqabunga ngokuvamile siqala kusukela ekugcineni kweqabunga futhi sisakazeka phakathi nemithambo yegatsha ngendlela "V".
Ekuqaleni, ifana namanzi, futhi ngemva kokukhula, iba nsundu ngokuphuzi, inemiphetho engajwayelekile kanye nezimpawu zamasondo ezimnyama nezilula ezishintshanayo.
Umngcele phakathi kwezicubu ezigulayo nezinempilo usobala, futhi inani elincane lesikhunta esimpunga nesimhlophe sikhiqizwa phezulu.
Uma isiqu sithelelekile, siqala njengendawo encane ecwiliswe ngamanzi, bese sikhula sibe yi-oblong noma engavamile, insundu ngokukhanyayo. Lapho umswakama uphakeme, kuba nesikhunta esimpunga ebusweni bebala, futhi ezimweni ezimbi kakhulu, isiqu namaqabunga ngaphezu kwengxenye yesifo kuyafa.
Isifo sezithelo, ukucwaswa okusele noma amacembe aqala ukungenwa yilesi sifo, bese asakazwa esithelweni noma esihlangeni, okuholela ekutheni ikhasi libe mpunga, futhi kukhona ungqimba olumpunga oluqinile, njengokubola kwamanzi.
indlela yokulawula
Ukulawulwa kwezolimo
- Ukulawulwa kwemvelo
Ukungena komoya okufika ngesikhathi ekuseni ngezinsuku ezinelanga, ikakhulukazi endaweni ebamba ukushisa kwelanga ngokunisela amanzi, osukwini lwesibili kuya kweyesithathu ngemva kokunisela, vula i-tuyere imizuzu engu-15 ngemva kokuvula ikhethini ekuseni, bese uvala umoya. Lapho izinga lokushisa ku-greenhouse yelanga likhuphukela ku-30 ° C, bese uvula kancane kancane i-tuyere. Izinga lokushisa eliphezulu elingaphezu kuka-31℃ linganciphisa izinga lokuhluma kwezinhlamvu futhi linciphise ukuvela kwezifo. Emini, izinga lokushisa ku-greenhouse yelanga ligcinwa ku-20 ~ 25 ° C, futhi umoya uvaliwe lapho izinga lokushisa lehla liye ku-20 ° C ntambama. Izinga lokushisa ebusuku ligcinwa ku-15 ~ 17 ℃. Ngezinsuku eziguqubele, ngokusho kwesimo sezulu kanye nemvelo yokulima, umoya kufanele ukhululwe kahle ukuze unciphise umswakama.
- Ukutshalwa kokulawula izifo
Khuthaza ukutshalwa kwefilimu encane nephezulu ye-cardigan mulching, ufeze ubuchwepheshe bokuchelela nge-drip, unciphise umswakama futhi unciphise izifo. Ukunisela kufanele kwenziwe ekuseni ngezinsuku ezinelanga ukuze kuvinjelwe ukweqisa. Ukuchelela okulingene ekuqaleni kwesifo. Ngemuva kokuchelela, qaphela ukukhipha umoya nokususa umswakama. Ngemuva kwalesi sifo, susa izithelo ezigulayo namaqabunga ngesikhathi futhi ubhekane nazo ngendlela efanele ukuze uvimbele ukusabalala kwamagciwane. Ngemuva kokuqoqwa kwezithelo nangaphambi kokutshala izithombo, insalela yesifo iyasuswa ukuze kuhlanzeke insimu futhi kuncishiswe ukutheleleka kwamagciwane.
- Ukulawula ngokomzimba
Ukusetshenziswa kwehlobo nekwindla lokushisa eliphezulu, ivaliwe abamba ukushisa elanga isikhathi esingaphezu kwesonto, ukusetshenziswa kwelanga ukwenza izinga lokushisa ku-greenhouse likhuphuke libe ngaphezu kuka-70 ° C, izinga lokushisa eliphezulu disinfection.
Ukulawula amakhemikhali
Ngokwezici zesikhunta esimpunga sikatamatisi, kuyadingeka ukukhetha izinhlobo ezifanele zemithi ukuyilawula ngokwesayensi. Lapho utamatisi ucwiliswa ezimbalini, ku-diluent yembali yediphu elungisiwe, u-50% yenani lempushana emanzi ye-saprophyticus, noma u-50% wempushana emanzi ye-doxycarb, njll., yengezwa ukuvimbela ukutheleleka ngebhaktheriya. Ngaphambi kokutshala, utamatisi kufanele uhlanzwe kahle ngesibulala-magciwane nge-50% carbendazim powder emanzi izikhathi ezingu-500 uketshezi, noma u-50% we-Suacrine wettable powder izikhathi ezingu-500 uketshezi fafaza kanye ukuze unciphise inani lamagciwane e-pathogenic. Ekuqaleni kwalesi sifo, uketshezi oluphindwe izikhathi ezingu-2000 luka-50% Suk flexible wettable powder, uketshezi oluphindwe izikhathi ezingu-500 luka-50% carbendazam wettable powder, noma izikhathi ezingu-1500 uketshezi lwempushana emanzi engu-50% ye-puhain lwalusetshenziselwa ukuvimbela nokulawula isifutho, kanye njalo izikhathi ezingu-7 Izinsuku eziyi-10, izikhathi ezi-2 kuye kwezi-3 zilandelana. Ungaphinda ukhethe u-45% we-Chlorothalonil ebenzela intuthu noma u-10% we-ejenti yentuthu ye-Sukline, amagremu angu-250 i-mu greenhouse ngayinye, i-greenhouse evaliwe ngemva kwezindawo ezingu-7 kuya kweziyi-8 kusihlwa ukuze kukhanye ukuvimbela intuthu. Uma lesi sifo sisibi, ngemuva kokukhipha amaqabunga agulayo, izithelo neziqu, ama-ejenti angenhla nezindlela zithathwa ukuze kuvinjelwe futhi zelashwe izikhathi ezi-2 kuya kwezi-3.
