Effects of seaweed fertilizer on growth and nutrient absorption of wild vegetable Plantago asiatica
摘要
Abstract
To explore the effects of seaweed fertilizer on the growth and nutrient absorption of wild vegetable Plantago asiatica,and screen out the optimal fold dilution of seaweed fertilizer that was beneficial to the growth and nutrient ab-sorption of P.asiatica,a pot experiment was conducted to study the effects of five fold dilutions of seaweed fertilizer[0(CK),600(T1),900(T2),1200(T3),and 1500(T4)-folds]on the growth and nutrient absorption of P.asiatica.The results showed that compared with CK,the different fold dilutions of seaweed fertilizer treatments increased the biomass(root biomass and above-ground biomass),photosynthetic pigment(chlorophyll a,chlorophyll b and carotenoids)content,root and above-ground total nitrogen content,root and above-ground total potassium content,as well as soil alkali-hydro-lyzable nitrogen and available potassium content,T1 treatment showed the optimal enhancement effects on the root bio-mass,above-ground biomass,chlorophyll a content,chlorophyll b content,carotenoid content,which increased by 18.36％,31.57％,11.94％,22.22％,19.49％,respectively,compared with control.Treatment T2 produced the highest total potassium concentrations in roots and aboveground parts of P.asiatica,which were 43.98％and 8.11％higher than CK correspondingly.Therefore,seaweed fertilizer can promote the growth and nutrient absorption of P.asiatica,with the best dilution of 600-fold.关键词
