磷和钾对大灰藓植株生长生理和营养元素的影响
Effects of Phosphorus and Potassium on Growth Physiology and Nutrient Elements of Hypnum plumaeforme
摘要
Abstract
Hypnum plumaeforme has good landscape effect and application prospect,but its slow growth and lack of systematic cultivation technology research have a certain impact on its popularization and application.Phosphorus fertilizer(P),potassium fertilizer(K)and PK compound fertilizer were used as single-use base fertilizer,respectively,and the growth physiology and nutrient changes were studied under different fertilization treatments,and the best fertilization treatment was selected by fuzzy membership function method.The results showed that fertilization could significantly increase the coverage of H.plumaeforme,and the coverage under K18 was 53.9%higher than that of control(CK).Fertilization significantly increased the contents of carotenoids,chlorophyll(except for K12)and soluble protein(except P24,PK12 and PK30),but decreased the soluble sugar content(excluding P24 and PK6).The contents of carotenoid and chlorophyll in plants treated with P18 were the highest,which were 3.42 times and 2 times that of CK,respectively.P fertilizer significantly increased P content in plant,and P18 had the greatest effect,which was 1.33 times that of CK.K fertilizer had the best promoting effect on the accumulation of K content in plants,and the K content in plants treated with K18 was the highest(1.62 times that of CK).Fuzzy comprehensive evaluation showed that K18 and P18 had the best promotion effect on improving plant coverage and maintenance of greenness,respectively.Therefore,P18 treatment had the best effect on enhancing growth and plant color.关键词
