Phytophthora: Control and ekudzivirira nzira

Late nenyunje - kutyisidzira fungal chirwere kukanganisa kunyanya Solanaceae (mbatatisi, tomato eggplant, pepper, etc.). It unoritumidza chakuvhe Phytophthora infestans, iyo kuchengetwerwa nzvimbo kazhinji kutenga-tubers kana mizambiringa yakabva kumwe. The zvinokonzera chirwere kunogonawo kusiyiwa yechando mashizha romupfudze. The spores pamusoro Phytophthora, mwaka wechando, chikonzero chirwere ari chirimwa chitsva. Rwisa chirwere ichi zvakaoma chaizvo. Nyore kudzivirira kukura kwayo.

Phytophthora, kuzvidzora nzira dziri kunyanya vari kudzivirirwa, hwacho zvirimwa kunyanya yechipiri yezana yezhizha. Naizvozvo, zvakakosha kuti usatadza nguva rokusima matapiri. The kupfuura Zvakanyanya Kunaka Panguva Yepamuviri nguva - ndiro gumi April rechipiri. Asati randakasima, ivhu rinofanira anoputsa. pazororo dzakawanda munguva kwenheyo tubers vari mugomba kukanda tsama mupfudze. Muchiitiko chino, zvakakosha kuona chipimo chemushonga kodzero. Chokwadi chokuti pachisara pakati senitrogen muvhu - mumwe mukuru zvikonzero kukura vachangobva kukanganiswawo. Naizvozvo hazvina kukodzera kunyanya kuti isa fotereza ivhu mupfudze.

Vamwe nderwevaya kuti potashi uye phosphate fetiraiza pamusoro zvinopesana kunoderedza ngozi kwezvirwere zvakadai mukupera kukanganiswawo. Nzira yokubata nayo zvikuru kunzwisisa uye kazhinji isashande. Saka, imwe nzira yakanakisisa kudzivirira kukura kwayo anogona kunzi kushandisa nzvimbo chete kugadzikana nokuda kwake mamakisi. Izvi zvinogona kuva "aika", "Gatchina", "tafura 19" uye vamwe.

Kazhinji, kunopera nenyunje mu matapiri kunoratidzwa munyaya kana yakura kwemakore akawanda pamusoro chete panzvimbo. Muchiitiko chino, zvishoma nezvishoma kuunganidza, hweHIV yekudyidzana kunoderedza zvibereko. Mumwe hazvifaniri kudyarwa pedyo mbatatisi munda madomasi. Mukupera nyaya zvingakanganiswa zvetsika. Roots vasati kudyara hazvo arongwe panze, kurasa zvose zviduku, ndakashata uye kurwara. Zvakanakisisa kuvatsigira pavhiki kana maviri ari kudziya 16-18 magiramu. Celsius. Panguva iyi, mushakabvu nenyunje nzvimbo dzinooneka, saka kubvisa hosha tubers zvichava nyore.

Potato mushakabvu nenyunje zvinokonzerwa anomuuraya ari inotonhorera yechirimo kuchinaya. Muchiitiko ichi zvakafanira kuderedza uwandu irrigations. A nguva inokosha chaizvo kubvisa masora, zinyekenyeke zvinomera, uye kuitisa hilling. A gobvu rukoko ivhu pamusoro tubers haingasviki pinda navo fungal spores kubva mashizha uye mapazi.

Zvisinei, kana, mushakabvu nenyunje ragunzva zvirimwa zvenyu, iwe uchava guru uye rakaoma basa. Chokutanga, unofanira kubvisa zvose utachiona mashizha madzinde. Ipapo matapiri kubatwa zvinodhaka fungicides. Uyewo hazvina kuzvigona pamwe chirwere Bordeaux musanganiswa. Zvisinei, zvakanaka kuti vanoshandisa zvishandiso itsva. Chokwadi kuti mukupera nenyunje, kuzvidzora nzira iyo inosanganisira kushandisa zvinodhaka mhangura tubhokisi, nokukurumidza mutates uye zvinoenderana vose kushanda nazvo makemikari.

Mune zvimwe zviitiko, rinobatsirawo uye zvakatipoteredza noushamwari chizvarwa chitsva microbiological nevamiririri. Nheyo yokuvhiyiwa nyore: bacteria dzavo constituent kana kunyikwa mumvura kusashanda, uye substrate mhinduro iri madzinde mapazi dzinotanga kuparadza chakuvhe. With mvura mvura, ivo kupinda muvhu, kubatsira kuchenesa paurwere uye tubers. Saka, zvinokwanisika here kukurira "mukupera nenyunje" chirwere. Nzira yokubata nayo makemikari, Chokwadi, unogona kunzi okunyanyisa. Zvisinei, kushandisa microbiological yomuchipatara ichapa kusvibiswa zvinokuvadza yeimwe pakukohwa. Panyaya iyi, kusarudza rangano wehondo.
