Arbuscular mycorrhizal(AM) fungi can establish a good symbiotic relationship with tobacco roots, thus facilitate its growth and improve quality of the host. It is an impending problem to ascertain whether spraying agricultural chemical has effects on the tobacoo inoculated AM fungi.This research inoculated with Glomus mosseae fungi tobacco on which had sprayed with various kinds of agricultural chemical.The infection rate of AM fungi,the vigor of the root system and the No.of soil spores were measured. According to all these indexes,we assayed the effect of spraying agricultural chemical on tobacco inoculated with AM fungi,which could be used as a guide to producing tobacco.

Through systemic study on the rhizospheric niche of seedlings inoculated with arbuscular mycorrhizal (AM) fungi, we found that the niche of the host-plant was affected vitally by AM fungi. The selected four AM fungi Glomus mosseae, G. intraradices, G. sinuosa, G. versiforme infected the potted seedlings of Populus ussruiensis and formed mycorrhizal compound with the host plant. Glomus mosseae and G. intraradices have better infection rate than the others. Their infection rates...

Through systemic study on the rhizospheric niche of seedlings inoculated with arbuscular mycorrhizal (AM) fungi, we found that the niche of the host-plant was affected vitally by AM fungi. The selected four AM fungi Glomus mosseae, G. intraradices, G. sinuosa, G. versiforme infected the potted seedlings of Populus ussruiensis and formed mycorrhizal compound with the host plant. Glomus mosseae and G. intraradices have better infection rate than the others. Their infection rates were 64.4%, 67.4%, respectively. The biomass of seedlings infected by the two AM fungi were 2.59, 2.13 times of control, respectively. AM fungi don抰 affect on microbial populations in rhizospheric soil, but increase the number of bacteria, actinomycetes and azotobacter in the root surface and root surround area. AM fungi accelerated the activities of phosphatase, urease, and proteinase in soil rhizosphere, and the activities of these enzymes were positively correlated with the infection rate of AM fungi. AM fungi decreased the pH value of rhizosphere, but the pH value is correlated with the infection rate of AM fungi negatively. The nutrient gathering of available N and P in the rhizosphere of the seedlings inoculated with AM fungi was found, and it was correlated with the infection rate of AM fungi remarkably.

对接种AM菌根真菌的大青杨苗木根际微区进行系统研究,发现AM菌根真菌对宿主根际微域环境产生了重要影响。试验中选用的Glomus mosseae、G. intraradices、G. sinuosa、G. versiforme等4种AM菌根真菌都与盆栽大青杨苗木形成了菌根复合体。其中G. mosseae、G. intraradices侵染效果最好,侵染率分别是64.4%、67.4%。受两种菌侵染的苗木的生物量分别是对照处理的2.59、2.13倍。AM菌根对根际土壤微生物种群数量没有产生影响,但使根面、根系上的细菌、放线菌、固氮菌的数量显著增加。AM菌根增加了根际土壤磷酸酶、脲酶、蛋白酶的活性,各种酶活性增加量与苗木菌根侵染率呈显著相关。AM菌根使根际pH值降低,与菌根侵染率呈显著负相关。接种苗木的根际土壤中,可直接被植物吸收利用的N、P元素出现富集现象,与菌根侵染率呈极显著相关。

In pot experiments, the trail results showed that herbicides of acetochlor, butachlor, glyphosate-isopropylammonium, aventis and quizalofop-p-ethyl reduced significantly the biomass of soybean, infection rates of AM fungus, mycelium enzyme activity of ALP and SDH, and total mycelium amount of AM fungi in the soil. After treatment for 6 weeks, acetochlor and butachlor decreased remarkably the biomass of soybean (the biomass was 12.6-15.5 g), however, quizalofop-p-ethyl had the less impact...

In pot experiments, the trail results showed that herbicides of acetochlor, butachlor, glyphosate-isopropylammonium, aventis and quizalofop-p-ethyl reduced significantly the biomass of soybean, infection rates of AM fungus, mycelium enzyme activity of ALP and SDH, and total mycelium amount of AM fungi in the soil. After treatment for 6 weeks, acetochlor and butachlor decreased remarkably the biomass of soybean (the biomass was 12.6-15.5 g), however, quizalofop-p-ethyl had the less impact on biomass of soybean (the biomass was 20. 8-23.5 g), and the biomass of trail control was 29.5-30.8 g; butachlor reduced significantly the infection rates of AM fungi (AM fungal infection rates were 17. 4%-24.1 % ) , acetochlor and glyphosate-isopropylammonium had the less impact on the infection rates of AM fungi (the infection rates were 29. 3%-32.2%) , while the infection rates of the controls were 78.5%-62. 4% ; butachlor also influenced significantly the enzyme activity of AM mycelium ALP and SDH (ALP were 10. 2%-13. 6%, SDH were 13. 5% -18. 8%) , acetochlor and glyphosate- isopropylammonium had the less impact on the enzyme activity of AM fungi mycelium ALP and SDH (ALP was 13. 9%-17. 8%, SDH was 19. 8%-25. 0%), while the mycelium ALP of the control was 47. 0%-36. 3%, the mycelium SDH of the control was 62. 7% -48.4%; besides, herbicides also reduced significantly total mycelium amount of AM fungi in the soil.

在接种Glomus intraradices和Glomus mosseae的大豆植株盆栽钵中,按大田常规用量,施用乙草胺、丁草胺、灵达、骠马和精喹(禾灵)5种除草剂,显著减少了大豆植株的生物量和土壤中AM真菌菌丝的总量,降低了丛枝菌根(arbuscular mycor-rhiza,AM)真菌侵染率、菌丝碱性磷酸酶(alkaline phosphatase,ALP)和琥珀酸脱氢酶(succinate dehydrogenase,SDH)活性。处理6周后,显著降低大豆植株生物量的除草剂为乙草胺和丁草胺,植株生物量前者为12.6、14.5 g,后者为12.7和15.5 g,影响较小的为精喹(禾灵)(植株生物量各为20.8、23.5 g),而对照的生物量为29.5、30.8 g;显著减少AM真菌侵染率的除草剂为丁草胺(AM真菌侵染率为17.4%、24.1%),影响较小的为乙草胺和灵达(前者为29.3%、30.7%,后者为26.3%和32.2%),而对照侵染率为78.5%、62.4%;显著降低AM真菌菌丝ALP和SDH酶活性的除草剂为丁草胺(ALP为10.2%、13.6%,SDH为13.5%、18.8%),影响较小的为...
