| Abstract: |
| A…field…plot…experiment…was…conducted…to…evaluate…the…effects…of…microbial…agents…including…Bacillus
subtilis， Trichoderma harzianum and…Bacillus amyloliquefaciensFZB42…on…disease…occurrence， growth， root…dry…weight
（DW）and…effective…component…of…different…parts…of…three-year…old…Panax notoginseng.…The…results…showed…that…3…kinds…
of…microbial…agents…all…had…effects…on…disease…control， growth， total…DW…and…total…saponins…of…P. notoginseng.…The…ratio…of…
disease…occurrence…was…13.25%…of…C 1 …with…good…control…effect…and…the…order…of…control…effect…was…C 1 ＞ A ＞ C 2 ＞ C 4 ＞
C 5 ＞ B ＞ C 3 ＞ CK 2 ＞ CK 1 .…C 1 …had…the…most…impact…on…plant…height， stem…diameter…and…snip…coarse， made…them…rise…by…
41.11%， 44.44%…and…33.96%…respectively…compared…to…CK 1 ； C 4… had…the…most…impact…on…length…and…width…of…leaf， made…
them…rise…by…37.13%…and…24.27%…respectively…compared…to…CK 1 .…The…order…of…control…effect…on…root…DW…was…C 1 ＞ C 3
＞ C 4 ＞ B ＞ A ＞ CK 2 ＞ C 2 ＞ C 5 ＞ CK 1 .…The…total…saponins…of…snip…and…fibrous…in…C 3 …rose…by…69.15%…and…248.24%…
compared…to…CK 1 ， while…by…87.34%…and…378.71%…compared…to…CK 2 ， the…total…saponins…of…taproots…and…snip…in…C 1 …rose…by…
59.61%…and…36.78%…compared…to…CK 1 ， while…by…205.01%…and…51.49%…compared…to…CK 2 .…The…results…indicated…that， C 1
（97…mL/667m 2 ）treat…ment…played…a…significant…promotion…role…for…both…disease…prevention…and…control， growth， yield…
and…quality.… |
