几种微生物菌剂对三七生长发育及品质的影响

通过田间小区试验,研究枯草芽孢杆菌(A)、哈茨木霉(B)、德根贝(C_1、C_2、C_3、C_4、C_5)等微生物菌剂对3年生三七植株的病害发生情况、生长发育、地下部分干物质产量和三七根部不同部位有效成分含量的影响。结果表明,3种微生物菌剂对三七植株的病害防治、生长发育、总干重、总皂苷含量均有一定的作用。处理C_1的植株发病率为13.25%,防治效果最佳;各生物菌剂对三七病害防治作用效果大小依次为:C_1〉A〉C_2〉C_4〉C_5〉B〉C_3〉CK_2〉CK_1。处理C_1对三七的株高、茎粗和剪口粗影响最大,比CK_1分别提高41.11%、44.44%和33.96%。处理C4对三七的叶长、叶...

Description
Summary:通过田间小区试验,研究枯草芽孢杆菌(A)、哈茨木霉(B)、德根贝(C_1、C_2、C_3、C_4、C_5)等微生物菌剂对3年生三七植株的病害发生情况、生长发育、地下部分干物质产量和三七根部不同部位有效成分含量的影响。结果表明,3种微生物菌剂对三七植株的病害防治、生长发育、总干重、总皂苷含量均有一定的作用。处理C_1的植株发病率为13.25%,防治效果最佳;各生物菌剂对三七病害防治作用效果大小依次为:C_1〉A〉C_2〉C_4〉C_5〉B〉C_3〉CK_2〉CK_1。处理C_1对三七的株高、茎粗和剪口粗影响最大,比CK_1分别提高41.11%、44.44%和33.96%。处理C4对三七的叶长、叶宽影响最大,比CK1分别提高37.13%、24.27%。各生物菌剂处理对三七地下部分干重的影响效果大小依次为:C_1〉C_3〉C_4〉B〉A〉CK_2〉C_2〉C_5〉CK_1。处理C_3的剪口和须根的总皂苷含量分别比CK_1提高69.15%、248.24%,分别比CK_2提高87.34%、378.71%;处理C_1主根和剪口的总皂苷含量分别比CK_1提高59.61%和36.78%,分别比CK_2提高205.01%和51.49%。综合来看,处理C_1(97 mL/667m~2)对三七的病害防治、生长发育、产量及质量等方面均有显著的促进作用,可在生产中推广应用。

Panax notoginseng; microbial agent; disease control; growth and development; effective component
A field plot experiment was conducted to evaluate the effects of microbial agents including Bacillus subtilis,Trichoderma harzianum and Bacillus amyloliquefaciens FZB42 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 C4C_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 comp
