氮磷钾配施对工业大麻干物质和养分积累与分配的影响
Effects of Combined Application of N,P,K Fertilizers on Accumulation and Distribution of Dry Matter and Nutrients in Industrial Hemp (Cannabis sativa L.)
摘要
Abstract
Effects of combined fertilization of nitrogen,phosphorus and potassium on growth and accumulation and distribution of dry matter and N,P,K nutrients in industrial hemp cultivar Yunnan hemp 1 were studied via pot culture.Nitrogen was the main factor determining the growth and yield, while the effect of phosphorus was not significant if nitrogen and potassium were enough.P and K fertiliz-ers affected the bast fiber yield little,if nitrogen was deficient.Being compared with NPK and NK,NP impeded the growth and dry matter accumulation.PK treatment promoted phosphorus accumulation but impeded potassium accumulation,while NK treatment facilitated the accumulation of both nitrogen and potassium.Hemp consumed potassium mostly,nitrogen secondly,phosphorus least.The results showed that NPK contributed differently to the growth and yield.There were mutual benefits and antagonistic ac-tion between the three elements,which affected the absorption and utilization of them in hemp.关键词
