Cov lus qhia rau Bacillus thuringiensis

Qhov zoo ntawmBacillus thuringiensis yog ib yam kab mob

(1) Cov txheej txheem tsim khoom ntawm Bacillus thuringiensis ua tau raws li qhov yuav tsum tau ua ntawm ib puag ncig, thiab muaj cov seem seem tsawg dua tom qab txau tshuaj tua kab.
(2) Bacillus thuringiensis cov tshuaj tua kab raug nqi tsawg, nws cov khoom siv raw khoom los ntawm ntau qhov chaw, yog kev ua liaj ua teb, los ntawm cov khoom, tus nqi kuj pheej yig.
(3) Cov khoom lag luam muaj cov kab mob dav dav thiab muaj tshuaj lom rau ntau tshaj 200 hom kab tsuag lepidoptera.
(4) Kev siv tsis tu ncua yuav ua rau thaj chaw muaj kab mob sib kis, ua rau muaj kev sib kis ntawm cov kab mob sib kis, thiab ua tiav lub hom phiaj ntawm kev tswj hwm ntuj ntawm cov kab kab.
(5) Kev siv cov tshuaj tua kab Bacillus thuringiensis tsis muaj kuab paug rau ib puag ncig thiab dej, tsis muaj kev phom sij rau tib neeg thiab tsiaj txhu, thiab muaj kev nyab xeeb rau cov yeeb ncuab ntau yam kab.
(6) Bacillus thuringiensis tuaj yeem sib xyaw nrog ntau yam ntawm lwm cov tshuaj lom neeg, cov tshuaj tua kab loj hlob, pyrethroid silkworm co toxins, carbamates, tshuaj tua kab organophosphorus thiab qee cov fungicides thiab tshuaj chiv.
(7) Kev siv cov tshuaj tua kab thiab tshuaj tua kab sib xyaw tuaj yeem txhim kho cov kab mob tsis zoo rau cov tshuaj tua kab.

Txoj kev siv

Tshuaj tua kabBacillus thuringiensis npaj tuaj yeem siv rau kev txau, txau, sau, ua cov granules lossis tshuaj lom kab, thiab lwm yam, tuaj yeem txau los ntawm cov dav hlau loj hauv cheeb tsam, thiab tseem tuaj yeem sib xyaw nrog cov tshuaj tua kab tsawg los txhim kho kev tswj xyuas. Tsis tas li ntawd, cov kab tuag tseem tuaj yeem rov qab siv dua, cov kab dub thiab lwj lub cev yuav raug tshuaj lom los ntawm Bacillus thuringiensis, rubbed rau hauv dej, thiab txhua 50 grams ntawm cov tshuaj tua kab mob yuav tsum tau txau nrog 50 mus rau 100 kilograms dej, uas. muaj kev tswj kom zoo dua rau ntau yam kab tsuag.

(1) Kev tiv thaiv thiab tswj cov kab tsuag nyom: Txau nrog 10 billion spores / g ntawm cov kab mob hmoov 750 g / hm2 diluted nrog dej 2 000 zaug, los yog sib tov 1 500 ~ 3 000 g / hm2 nrog 52.5 ~ 75 kg ntawm cov xuab zeb zoo. ua granules thiab tawg rau hauv cov cag nyom kom tiv thaiv thiab tswj cov kab tsuag uas ua rau cov hauv paus hniav.
(2) Kev tiv thaiv thiab kho pob kws borer: 150 ~ 200 grams ntawm wettable hmoov ib mu, 3 ~ 5 kg ntawm nplua xuab zeb, sib tov thiab tawg nyob rau hauv lub plawv nplooj.
(3) Kev tiv thaiv thiab kho kab mob cab cab, kab npauj kab mob, kab npauj kab mob, kab mob khaub thuas, kab mob khaub thuas: 100 ~ 150 grams ntawm wettable hmoov ib mu, 50 kg ntawm dej tsuag.
(4) Kev tiv thaiv thiab tswj cov paj rwb, paj rwb bollworm, choj worm, nplej, nplej nplooj ntoos borer, borer: 100 mus rau 200 grams ntawm cov hmoov ntub dej rau ib mu, 50 mus rau 70 kilograms ntawm cov tshuaj tsuag dej.
(5) Kev tswj cov txiv hmab txiv ntoo, ntoo, ntoo thuv kab ntsig, zaub mov worms, inchworms, tshuaj yej caterpillars, tshuaj yej inchworms: txhua mu nrog wettable hmoov 150 ~ 200 grams / mu, dej 50 kg tsuag.
