为筛选出对头花蓼连作障碍调控效果较好的肥料品种,研究阿姆斯生物肥、地宝生物肥、药渣菌肥(RW促腐剂)、头花蓼专用肥等几种肥料对头花蓼连作土壤中栽培植株生长、产量、营养元素及土壤微生物的影响.结果表明:头花蓼连作不施肥的产量较低,仅247 kg/667m2,土壤中微生物放线菌>细菌>真菌.施肥后头花蓼1级、2级分蘖数分别比不施肥处理增加62.5%~125%和41.18%~123.53%;产量提高55.87%~418.62%;根、茎、叶中总元素含量分别提高0.97%~16.39%、6.33%~23.14%和3.59%~34.85%,花中含量降低0.78%~5.69%;槲皮素、没食子酸含量分别超过0.38%和0.51%,水分含量<12%,但差异不大;土壤中微生物细菌>放线菌>真菌.其中,以基肥施药渣菌肥(RW促腐剂)300 kg/667m2、头花蓼专用肥44.47kg/667m2,追肥施头花蓼专用肥11.12 kg/667m2的调控效果最好;基肥施地宝生物肥333.5 kg/667m2、头花蓼专用肥44.47 kg/667m2,追肥施头花蓼专用肥11.12 kg/667m2次之.
Regulation of Several Fertilizers on Continuous Cropping Obstacle of Polygonum capitatum
In order to screen the fertilizers with better control effects on continuous cropping obstacle of P.capitatum,the influence of several fertilizers,including Armes bio-fertilizer,Dibao bio-fertilizer,RW transformation promoter and fertilizer for P.capitatum,on plant growth,yield,nutrients and soil microbes of P.capitatum in continuous cropping soil were studied.Results:The yield of continuous cropped P.capitatum was low,merely 247 kg/667m2,soil microbes followed the sequence of actinomycetes > bacteria > fungi.Compared with non-fertilizer treatment,fertilizer application increased the 1st and 2nd tiller number of P.capitatum by 62.5 %-125 % and 41.18 %-123.53 % respectively.Yield,gross elements content in root,stem and leaf increased by 55.87 %-418.62 %,0.97 %-16.39 %,6.33 %-23.14 % and 3.59 %-34.85 % separately.Nonetheless,the gross elements content in the flower decreased by 0.78 %-5.69 %;Contents of quercetin and gallic acid were above 0.38 % and 0.51% respectively.The moisture content was below 12 % with little difference;Soil microbes bacteria > actinomycetes > fungi.Base fertilizer RW transformation promoter 300 kg/667m2 and fertilizer for P.capitatum 44.47 kg/667m2 + topdressing fertilizer for P.capitatum 11.12 kg/667m2 had the best control effects,followed by fertilizer for P.capitatum 44.47 kg/667m2 + topdressing fertilizer for P.capitatum 11.12 kg/667m2.
