Kukohwa tembiricha zvinokonzerwa

Huwandu hwemamiriro ekunze panguva yekukohwa hunogona kunge hwakakura zvichienderana nemamiriro ekunze ezuva nezuva uye nguva yezuva. “Yakanaka” mamiriro ekukohwa ane tembiricha yetuber pulp iri pakati pe50 kusvika 55°F.

Chokwadi, zvinokurudzirwa ndezvekukohwa pakati pe45 ne65°F. Kutarisa tembiricha ye pulp uye kugadzirisa nguva dzekukohwa mukati mezuva kungave kuri madikanwa kuwira mukati meiyo tembiricha. Tembiricha iyi inogona kugadziridzwa kana kukohwa mumunda une matombo, kurima mhando inotapurika, kana mamiriro ekukura mumunda akawedzera kusaita mavanga kana zvirwere zvakaita sestress, kufa nekukurumidza, uye kudiridza zvakanyanya kana kushomeka.

Cold pulp tembiricha mhedzisiro:

Avoid harvesting potatoes with pulp temperatures less than 45°F. For varieties susceptible to Fusarium dry rot (for example Clearwater Russet, Umatilla Russet) it is recommended to harvest at pulp temperatures above 50°F. Cold temperatures increase the potential for potatoes to shatter bruise or fissures to occur and thus allow a perfect entry point for Fusarium dry rot or other pathogens to invade. Shatter bruises are also more difficult to wound heal due to the jaggedness of the wound. The damaged surface area of a potato can lose up to 500% more water compared to an undamaged area.

• Izvi zvinogona kubatsira zvakanyanya mukuderera kwese, kunyanya mukutanga kwemwaka wekuchengetedza apo kufema uye kurasikirwa kwekufema kuri pamusoro.

Mamwe marudzi, akadai seRanger Russet, anogona kurasikirwa nekugadziriswa kwemhando nekukasira kana akaiswa kune inotonhora tembiricha (<45°F). Kuwedzera kwekudzikisa shuga nekuda kwekutonhora kwekushisa kunoratidzwa hakugadzirise mukuchengetedza-kukuvadza kwatoitwa.

Kunopera kwemwaka wegoho panogona kunge kusisina mazuva akawanda anodziya uye mamwe mbatatisi anogona kunge ari kuenda kunochengeterwa pamatembiricha emhando yepamusoro. Pamwe mbatatisi idzodzo ndidzo dzinopedzisira kutakurwa mukamuri inochengeterwa mbatatisi inenge yakakohwewa pakudziya. Kana kuti zvakatonyanya kuwanda, mbatatisi dzinokohwewa mangwanani pakutonhora kunotonhora uye mbatatisi inokohwewa masikati patembiricha inodziya inounganidzwa mudura rimwe chete. Izvi zvinoita kuti pasarudze manejimendi akaomarara. Iko kukwanisa kwekugadzirisa mukati memurwi uye pamusoro pepamusoro yakakura. Ventilation ndiyo yakakosha pakugadzirisa kusiyana kwekushisa kwemurwi.

Zviri nani kuunza mhepo inenge 1 ° F-2F shoma pane mbatatisi inotonhora. Kana pasi pemurwi pasati pasvika 50 ° F, zvinokurudzirwa kuti zvishoma nezvishoma kubvumira murwi kuti udziye, asi uchiri kupa huwandu hwemhepo yakachena. Izvi zvichapa mamwe mamiriro akanaka ekuti maronda apore zviitike. Kupisa kwemoto mudura kwakakwira pakukohwa - 30+ BTU/cwt/zuva - saka pane kupisa kwakawanda kuri kugadzirwa kudziya murwi.

Mhedzisiro yekudziya kwepulp tembiricha:

Pane zvakati wandei zvinokonzeresa pakukohwa machubhu anodziya. Chekutanga, mukana wekurasikirwa nekuda kwekuora kwepingi uye kuvuza kwePythium kunowedzera zvakanyanya. Tembiricha yepulp iri pamusoro pe65 kusvika 70 ° F inowedzera zvakanyanya mukana wekuti mbatatisi ibatirwe nePythium kunyangwe pasina kukuvara kukuru. Zvakanakisa, zvakanaka kukohwa mbatatisi dzine tembiricha ye pulp iri pasi pe65°F kuderedza mukana wekuora kwetuber nekuda kwekudonha kwePythium.

Kunyange zvazvo kuora kwepink kusingadi ronda kuti kuparadze uye kuora tuber, mukana wekutapukirwa unowedzera zvakanyanya sezvo tuber inenge yakuvadzwa, kunyanya pamatembiricha ari pamusoro pe60 ° F. Kunyangwe iwe uchibata zvinyoro nyoro mbatatisi dzako, tembiricha yepulp ye70 ° F inowedzera njodzi yekuora kwepingi zvakanyanya kana inoculum iripo. Factor munjodzi iyi kana uchikohwa pa tembiricha yakakwira.

Sezvambotaurwa, kune huwandu hukuru hwekupisa huri kugadzirwa nembatatisi pakukohwa. Kana tembiricha ye tuber pulp yatokwira, uye kupisa kwekufema kwakakwira, izvi zvinoratidzira nhamba yekutanga yekuchengetedza manejimendi - bvisa kupisa uku nekukurumidza sezvinobvira. Panogona
kusave nemhepo yekutonhodza yakakwana iripo kuti uwane kutonga kwekupisa uku. Refrigeration isarudzo yakanaka yekutonhodza mbatatisi pakukohwa, kunyangwe sisitimu ichifanirwa kunge iine hunyanzvi hwekubata kupisa kwakanyanya uye mweya mutsva unofanirwa kupihwa kuchenesa kabhoni dhaidhi kubva muchivako.

Kana ukashandisa kunze kwemhepo inotonhodza chete, wedzera nguva yekumhanya nekuunza mweya mutsva mu1 kusvika 2 ° F yakaderera pane mbatatisi inotonhorera uye enderera neiyi nhanho yekudzika kusvika wasvika paunoda kurapa tembiricha. Mamwe mapaneru ekudzora nekombuta anogona kurongwa kuti aite izvi nepo mamwe uchifanirwa kuseta patsva nhanho imwe neimwe pasi mukupisa. Usangoise nzvimbo yakatarwa kusvika ku55 ° F - izvi hazvizokwidzi nguva yekumhanya. Iyo mbatatisi yakareba iri pamusoro pe55 ° F mukuchengetedza, iyo inowedzera njodzi yekuparara kwechirwere. Kufefetedza kwakakosha kuti uwane kutonga kwekupisa mutoro mukuchengetedza.

Ventilation system - kwakaringana lateral duct alignment:

chimwe nechimwe chengetedzo ventilation system yakagadzirirwa kupa huwandu hunodiwa uye chiyero chemhepo kune akawanda mbatatisi. Kuparadzirwa kwemhepo kwakakodzera kwakakosha kubata tembiricha uye kunetseka kwechirwere sezvatsanangurwa pamusoro apa. Chero shanduko mune iyi yakaomesesa yekugovera dhizaini inozokanganisa kudzoreredza uye yenzvimbo convection manejimendi uye tembiricha yakaenzana yemurwi. Iyo yekumusoro duct pombi inofanirwa kurongeka zvakanaka, yakabatana, uye yakavharwa kuendesa mweya se
zvinodiwa. Maburi ekugezera uye misaligned ducts haazopi mhepo kumurwi sezvakagadzirwa kana kudiwa. Kuve nechokwadi chekuti system iyi yakanyatsoenderana "inofanirwa" kutanga mwaka wekuchengetedza.
