In order to provide a theoretical basis for improving the technological level of production of Alisma plantago-aquatica Linn from Sichuan and establish standardized production base,we carried out research on effects of transplanting date and field structure on yield and quality Alisma plantago-aquatica.In this study,three factors and three levels orthogonal pilot program to explore effects of the yield and quality on transplanting period,wide and narrow row planting density on Alisma plantago-aquatica,The main conclusions are as follows:1.Effects of transplanting period and field structure on Alisma plantago-aquatica dynamic growthThere are effects of density and transplanting periodon the sichuan alisma corm size.Alisma tuber formation in the early,early and earliertransplanting period,medium density,row spacing and small spacing processing,tuber is significantly greater than other processing.In the middle of the jersey,early transplanting period,high density and smaller spacing is significantly greater than other treatment.High density in late diarrhea tuber bulking,promote the growth of its diameter.Integrated the whole growth period,conventional transplanting,medium density and the same space is the optimal combination of the bulb diameter growthfor alisma.2.Effects of transplanting period and field structure on Alisma plantago-aquaticamatter accumulationThere are effects of density and transplanting periodon the leaf fresh weight.Growth prophase,late transplanting period,high density,and row spacing is significantly greater than eralytransplanting period,high density and small spacing.Growth of middle,late transplanting period,high density,and equal spaceing is extremely significantly greater than earlytransplanting period,high density and smallerspacing treatment.At the later growth stage,the differences between the groups is not significant.The leaf fresh weight conventional transplanting,high density and smaller space combination achievesthe maximum average.There are effects of ransplanting period,density and spacingon leaf drying rate.Growth prophase,earliertransplanting period,high density,larger spacing is significantly greater than earliertransplanting period,smaller density and equal spacing.Growth in the middle,early transplanting period,medium density and equal spacing is significantly greater than the early transplanting period,low density and equal spacing.Earlier transplanting period,high density and small spacing is significantly greater than early transplanting period,high density and equal spacing.At later growth stage,the differences between the groups is not significantlater transplanting,high density and the same space is the optimal combination of leaf drying rate.There are effects of transplanting period,density and spacing on the bulb fresh weight.Growth prophase,late transplanting period,high density,and equal spacing is significantly greater thanearly transplanting period,high density and large spacing.Growth in the middle,earlier and late transplanting period,high density and equal spacing is significantly greater than latetransplanting period,low density and small spacing treatment.Earlier transplanting period,medium density and equal spacing is significantly greater than earlytransplanting,high and low density and spacing.The differences between the groups isnot significant at later growth stage.Bulb fresh on conventional transplanting,medium density and the same space combination conditions,reaches the maximum.There are effects of transplanting period and spacing on alisma bulb drying rate,Growth prophase,early transplanting period,high density and small spacing treatment is significantly earlier than late transplanting period,medium density and large spacing treatment.Grows metaphase,late transplanting period,low density and small spacing is significantly greater thanearly and earlier transplanting period,low density and spacing.The differences between the groups is not significant at later growth stage.Bulb Drying ratein combination later transplanting,low density and smaller space is the highest rate.3.Effects of transplanting period and field structure on Alisma plantago-aquaticamatter outputDensity is the key factor of production.Conventional transplanting,mediun density and bigger space and later transplanting,medium density and bigger space have a promoting effect on production.Conventional transplanting mediun density and bigger space and early transplanting,high density and bigger space have a promoting effect on yield.Conventional transplanting,mediun density and the same space get the lowest yield.40 cm spacing and 20 cm,has a promoting effect on yield formation.From the output data conventional transplanting,low density and the bigger space reaches the maximum value,and low density reaches the maximum yield of 566.95 kg/667 m2 instead4.Effects of transplanting period and field structure on Alisma plantago-aquaticamatter of qualityThere are effects of density and spacing of alisma alcohol b content.Growth prophase,earlytransplanting period,medium density and equal spacing is significantly more than the other treatment.Growth in the middleof early,early transplanting period,low density and equalspacing is significantly less than besidesearly and earliertransplanting period,high density and large spacing and row spacing in the other various treatment.The middle stage,early and late transplanting period,medium density and equal spacing treatment is significantly more than the others.Later,early and late transplanting period,low density and spacing treatment significantly more than the others.Late,early transplanting period and medium density and equal spacing get the maximum content,and behaves significantly greater than other treatment.conventional transplanting,medium density and the same space A2B2CI is the highest combination for alisma alcohol content b.Density and spacing have effects on the alcohol soluble extract.Growth prophase,late transplanting period,high density,and equal spacing is significantly greater than earlier transplanting period,low density and large spacing.Growth in the prophase,early transplanting period,high density and large spacing treatment is significantly greater than earlier transplanting period medium density and equal spacing.Later early transplanting period,high density and large spacing treatment is significantly greater than the late transplanting period,high density and equal spacing treatment.At late growth stage,early transplanting period,low density and equal spacing is significantly more than late transplantingperiod,high and middle density and equal space treatmen.Early transplanting,high density and the bigger space is the optimum combination for alisma alcohol soluble extract.There are effects of spacing and transplanting periodon the total ash content.Growth prophase,the differences between the groups is not significant.Growth in the middle,early transplanting stage,high density and small spacing is significantly greater than earlytransplanting period,high density and large spacing.But the difference was not significant between the groups at later growth stage.Later translanting,mediun density and the same space is the lowest total ash composition.There are effects of spacing and transplanting period of acid insoluble ash content.Growth prophase,late transplanting period,high density and spacing is significantly greater than latetransplanting period,middle and low density and spacing.Growth in the middle earlier transplanting period,high density and smaller spacing.is significantly greater thanlate transplanting period,low density and smaller spacing.At later growth stage,earlytransplanting period,high density and large spacing is significantly greater than early and late transplanting period,high density and spacing in the processing.Conventional transplanting,high density and smaller space is the optimal combination of acid insoluble ash content.There are effects of spacing and transplanting periodon the content of total triterpenoid.Growth prophase,early transplanting period,high density and large spacing is significantly greater thanearly and late transplanting period,low density and smaller spacing and row spacing.Growth in the middle prophase,earlytransplanting period,medium density and smaller spacing is significantly greater than late transplanting period,low density and equal spacing and small spacing.Growth in the middle,late transplanting period,high density and equalspacing issignificantly greater than early transplanting period,,low density and equal spacing treatment.Later,early transplanting period,medium density and smaller spacing treatment is significantly less than each processing of late transplanting period.At later growth stage,earlytransplanting period early,high density and large spacing treatment is significantly greater thanearly and late transplanting period,high density and equal space processing.Early transplanting,high density and the bigger space is the highest combination of alisma total triterpenoid content.There are effects of transplanting period and spacing has on the starch content.Growth prophase,earlier transplanting period,high density and small spacing is significantly less than early and late transplanting period,low density and large spacingtreatment.Growth in the middle prophase,early transplanting period,low density and equal spacing is significantly greater than late transplanting period,high density and equal spacing;Growth in the middle,earlytransplanting period,medium density and smaller spacing is significantly greater than early and late transplanting period,high density and spacing processing.Later,early transplanting period,medium density and equalspacing is significantly less than the late transplanting period,low density and spacing.At later growth stage,late transplanting period,high density and equal spacing is significantly greater than early and earliertransplanting period,all density and spacing Settings.Later transplanting,low density and the smaller space is the highest combination of starch content.There is different degree of effects of transplanting period,density and spacing on sichuan alisma production andquality.Appropriate phase transplanting period,density,spacing can effectively promote sichuan alisma the improvement of production and quality.In this study,combination later transplanting,mediun density and the bigger space is the optimal combination.According to the different requirements and needs to set the cultivation scheme.Later transplanting period can win more time for crop before,low density can decrease the cost of cultivation,the larger spacing can win more time and space for crop after.In this way,can we obtain greater economic benefits.
