Ndezvipi zvipembenene zvinogona kudziviswa neBacillus thuringiensis?

Bacillus thuringiensis, inozivikanwawo seBacillus thuringiensis var. popilliae, ibhakitiriya yakaita setsvimbo. Panguva yekubereka kwayo, mugumo mumwe unoumba spore, nokudaro ichiva spore-forming bacterium, nepo mumwe mugumo uchigadzira crystal proteins. Aya macrystal protein ane simba guru rekuuraya zvipembenene, kunyanya kune anopfuura 100 marudzi ezvipembenene zve lepidopteran zvakaita se cotton bollworm, small cabbage moth, diamondback moth, rice budworm, silkworm, pine caterpillar, tobacco budworm, corn borer, cotton bollworm, rice streaked stem borer, grass moth, uye ground beetle. Ibhakitiriya rezvipembenene rine hutachiona rave riri nyaya yekutsvagisa kwakadzama, kukura nekukurumidza, uye kushandiswa kwakanyanya mumakore achangopfuura. Nekuda kwehupfu hwayo hushoma, hushamwari kune zvakatipoteredza, uye kuuraya zvipembenene kwakanaka, inofarirwa zvikuru nevarimi.

I. Hunhu Hukuru hweBacillus thuringiensis

1. Mhando dzakasiyana dzekudzivirira zvipembenenel: Chepfu inogadzirwa neBacillus thuringiensis inogona kudzora mazana ezvipembenene, kunyanya inoshanda zvikuru pakurwisa lepidopteran larvae. Inonyanya kushandiswa kudzora makonye emakabheji, makonye edonje, turnip night moths, striped night moths, sugar beet night moths, small cabbage moth, tobacco moth, rechipiri-chizvarwa rice stem borers, corn borers, tea cattle, pine cattle, tea moth, bean moth, corn sticky pests, silver-winged night moths, uye mosquito larvae, pamwe nezvimwe zvipembenene zvakaita semabeetles, hozhwa, uye slugs.

2. Kusarudza: Bacillus thuringiensis inonyanya kurwisa zvipembenene zvine alkaline mudumbu mazvo uye ine simba guru rekuuraya. Haina chepfu kuvanhu, zvipfuyo, nyuchi, hove, shrimp, magakanje nezvimwe zvipenyu zvemumvura.

3. Kushandiswa kwakasiyana-siyana: Bacillus thuringiensis inogona kushandiswa zvakanyanya mudonje, nzungu, soya, mbatatisi, mupunga, rape, madomasi, maeggplant, mhiripiri, makabheji, makabheji eChinese, cauliflower, nezvimwewo miriwo, pamwe nemaapuro, miti yemapeya, mazambiringa, walnuts, michero yecitrus, lychees, kiwis, longans, mango, nezvimwewo. miti yemichero, uye zvakare muzvirimwa zvakasiyana-siyana zvakaita semaruva, mishonga yeChinese, nezvimwewo.

4. Hapana mushonga unorwisa zvipembenene: Bacillus thuringiensis rudzi rwebhakitiriya rinogadzira zvipembenene rinogona kugadzira mapuroteni ekristaro esporulation uye rinoshanda kunze uye mukati mezvipembenene. Zvipembenene hazvigone kuramba zvipembenene. Kunyangwe zvave zvichishandiswa kwemakumi emakore, zvichiri mushonga unorwisa zvipembenene wakanaka kusvika nanhasi.

5. Kuenderana kwakanaka: Bacillus thuringiensis inoenderana zvakanaka uye inogona kusanganiswa nemishonga inouraya zvipembenene inoshanda nekukurumidza senge methomyl, avermectin, uye indoxacarb, zvichikonzera mhedzisiro yakakura yekubatana.

6. Hapana kusvibiswa kunobva muchetura shanu: Bacillus thuringiensis ibhakitiriya ine chimiro chetsvimbo isina chepfu kuvanhu, hove, shrimp, gakanje, nezvimwewo, uye haikonzeri kusvibiswa kwezvakatipoteredza. Nokudaro, yava mushonga wezvipembenene unonyanya kufarirwa pakugadzira zvigadzirwa zvekurima zvakasvibira uye zvisina kusvibiswa.

II. Nzira dzekushandisa Bacillus thuringiensis

Kuti udzivise zvipembenene zvakaita seshuga beet moth, small cabbage moth, uye cabbage cattle, inogona kushandiswa panguva yemakonye apo zvipembenene zvinenge zvichiri zvidiki. Shandisa magiramu 30-40 e2% Avisept Bacillus thuringiensis wettable powder paeka, yakasanganiswa nemakirogiramu 30-40 emvura kuti upfapfaidze zvakaenzana. Izvi zvinogona kuuraya zvipembenene nekukurumidza uye zvinogara kwenguva refu nekukurumidza.

Kuti udzivise zvipembenene zvakaita se light moth, rice budworm, pine caterpillar, corn borer, large moth, uye needle moth, shandisa magiramu 25-35 e1% Avisept Bacillus thuringiensis wettable powder paeka, yakasanganiswa nemakirogiramu makumi matatu emvura kuti upfapfaidze zvakaenzana. Izvi zvinogona kukurumidza kudzora kukuvara kunokonzerwa nezvipembenene.

III. Kuchenjerera Bacillus thuringiensis

1. Shandisa pachine nguva: Sebhakitiriya, kana ikashandiswa yoga, kukurumidza kuuraya kunonoka. Saka, inofanira kushandiswa pakutanga kwekuitika kwezvipembenene kuti idzore zviri nani kukuvara kunokonzerwa nezvipembenene.

2. Shandisa masikati: Zuva rakasimba rinogona kuuraya utachiona uhwu. Saka, kana uchishandisa mushonga uyu wezvipembenene, zvakanaka kushandisa mushonga uyu usati wasvika 10am kana kuti mushure ma4pm, uye mhedzisiro yacho iri nani.

3. Shandisa kana tembiricha yakakwira: Bacillus thuringiensis inoshanda kana tembiricha yakakwira. Kana tembiricha yadarika 20℃, mhedzisiro yacho inova nani.
