为了探索草石蚕优质高产的合理施肥技术,试验以草石蚕为材料,研究了氮磷钾配施对草石蚕产量和品质的影响。结果表明:草石蚕单株结块茎数、单块茎重、大块茎率及产量均以处理N2P3K1最高,并均与处理N0P0K0差异显著,其中产量高达18992.00 kg/hm2,增产49.86%。 相似文献

Identification of tuber rot pathogen on Stachys sieboldii Miq. was carried out with morphological and molecular methods for the first time. Though the observation of morphology and color of the colonies,morphology of macroconidia, microconidia and chlamydospores, it was preliminarily identified as Fusarium oxysporum. The fungus DNA was amplified by PCR with the universal primers of fungal rDNA ITS1 and ITS4, and sequenced. The sequencing results were logged in GenBank to BLAST, and all of the molecular detections and morphologic observations showed that the pathogen was F. oxysporum. 相似文献

以草石蚕为试材,研究了不同浓度萘乙酸(NAA)处理对草石蚕扦插效果的影响。试验结果表明,在试验浓度范围内,各NAA浓度处理可促进草石蚕扦插苗的生根及生长,且随着NAA浓度的增加,其根长、根数、根鲜质量、根干质量、株高和根系活力均呈先上升后下降的趋势,其中以浓度为700 mg/L的NAA处理效果最好。 相似文献

在草石蚕(Stachys Sieboldii Mig.mip)试管苗继代培养阶段以MS为基本培养基,添加PP333浓度为8~10 mg/L能使试管苗明显矮化,茎节粗壮,试管苗的保存时期可延长至4~5个月;生根培养阶段以1/2MS NAA0.5 mg/L添加PPP333浓度为6~10 mg/L,能促进根系发育,改善根系质量,增强幼苗抗逆性,提高移栽成活率.移栽后缓苗期短,生长旺盛. 相似文献
