Effect of Organic Fertilizer on Economic Planting of Chinese Medicinal Materials in Broadleaf Forest in Pingtang County
The effects of organic fertilizer on economic planting of Chinese medicinal materials in broadleaf forest in Pingtang County were analyzed to provide technical support for economic planting of Chinese medicinal materials in the forest.In this study,a sample plot in Pingtang County was selected for experimental analysis,and 4 groups were set up.The fermentation of sheep manure organic fertilizer was included in group T1,the fermentation of pig manure organic fertilizer was included in group T2,the fermentation of chicken manure organic fertilizer was included in group T3,and the growth of Dendrobium dendrobium plants treated with different or-ganic fertilizer were analyzed.The experimental results showed that organic fertilizer had obvious effect on the planting of Chinese me-dicinal materials.The growth of new buds and leaves in T1 group was higher than that in CK group,and the growth number of new buds and leaves in T1 group was higher than that in other three groups at different time periods(P<0.05).After the application of or-ganic fertilizer,the stem height of Dendrobium laminata increased,and the stem growth index of Dendrobium laminata in T1 group was higher than that in the other three groups(P<0.05),and the stem growth reached the peak around October,and no longer increased,and there was a capping phenomenon.There was no significant difference in stem height between T2 and T3 groups(P<0.05).Stem length,stem diameter,fresh weight per cluster and water content in groups T1,T2 and T3 were higher than those in group CK(P<0.05),and the overall order was T1>T2>T3>CK.The alkaloid content,polysaccharide content,total flavone content and protein con-tent of organic fertilizer treatment were higher than those of no fertilizer treatment(P<0.05),and the alkaloid content,polysaccharide content,total flavone content and protein content of T1 group were higher than those of other groups(P<0.05).Overall,the advanta-ges of T1 treatment were more obvious.Therefore,it is concluded that the effect of planting Chinese medicinal materials and applying fermented sheep manure organic fertilizer under the broadleaf forest in Pingtang County is obvious Dendrobium,for example,can pro-mote the growth of Dendrobium sheaths and is recommended as a base fertilizer in organic cultivation.
