浅生槽定向栽培对铁棍山药块茎产量与质量的影响
Effects of Shallow Trough Directional Cultivation on Tuber Yield and Quality of Dioscorea opposita
摘要
Abstract
Objective:To find an efficient cultivation way of Dioscorea opposita,so as to enhance its medicinal value.Methods:Field experiments were conducted in randomized plots to study the effects of shallow trough cultivation(machine trenching and Luoyang shovel trenching)on character,yield,nutrients(amylose,amylopectin,soluble sugar and soluble protein)and active components(flavonoids,phenols,allantoin)in Dioscorea opposita.Results:Compared with the traditional cultivation,the tubers obtained under the two shallow trough directional cultivation methods had poor quality and the malformation rate was 100％.However,under the different planting den-sity(traditional 150 000 plants/hm2,shallow trough 17 850 plants/hm2),the weight per plant increased significantly,which was 6.17 to 7.84 times of the control,the theoretical yield had no significant differences.There were no significant differences in the contents of amylopectin,soluble protein in maintuber normal and malformed parts and the contents of amylose,phenols and flavonoids in main tuber normal part.The contents of phenols and flavonoids in malformed parts were significantly increased,and allantoin content in main tuber normal and malformed parts were significantly increased,which was 4.09 to 4.74 times of that in control.The content of soluble sugar in tuber increased significantly in the directional cultivation of shallow trough with machine grooving,but there was no significant difference between other samples.Conclusion:Although shallow trough directional cultivation can cause deformities of tuber,it can maintain its yield and nutrients,and significantly increase the content of effective components in malformed parts.Therefore,shallow trough direc-tional cultivation can be used as an efficient cultivation way to enhance the medicinal value of"authentic"medicinal materials Dioscorea opposita.关键词
