Effects of Different Types Plastic Film on the Growth,Yield and Main Active Ingredients of Angelica dahurica var.formosana
摘要
Abstract
In order to explore the effect of plastic film mulching technology on relieving spring drought of Angelica dahurica var.formosana seedlings,promoting its yield increase and ensuring its quality.A single-factor experimental design was applied in mulching to A.dahurica var.formosana grown in ridges and furrows using five different film mulching materials:white film(0.008 mm thickness),black film(0.008 mm thickness),black film(0.010 mm thickness),black film(0.014 mm thickness),and silver-black film(0.012 mm thickness).A control group with no mulch treatment(CK)was also included.The study aimed to analyze the effects of various film mulching types on growth dynamics,soil nutrients,plant nutrients,main active ingredient dynamics,yield,and economic benefits of A.dahurica var.formosana.The results showed that plastic film mulching significantly improved the soil available nutrient absorption,underground nutrient accumulation,yield,quality,and economic benefits of A.dahurica var.formosana.During the seedling stage,the plant height,root length,root diameter,fresh weight,and dry weight of plastic film mulching were higher than those of no mulch(CK).During the harvest period,the black film(thickness 0.010 mm)had the highest content and accumulation of imperatorin(0.31%,219.86 mg·plant-1).The accumulation of isoimperatorin was highest in silver black film,followed by black film(thickness 0.010 mm),with 75.25 mg·plant-1 and 71.75 mg·plant-1,respectively.Compared with CK,plastic film mulching yield increased by 18.15%-22.80%and economic benefits by 36.97%-54.12%.In summary,plastic film mulching technology can alleviate the drought phenomenon during the seedling stage of A.dahurica var.formosana,and further increase yield on the basis of improving the quality of A.dahurica var.formosana.Therefore,while taking into account the yield,main active ingredients,and economic benefits of A.dahurica var.formosana,it is advisable to ridge and ditch mulching it with thickness of 0.010 mm black film.The results of this study can provide theoretical reference for the application of plastic film mulching technology in the production of A.dahurica var.formosana.关键词
