Abstract:
Taking one-year-old scion-root seedling of A.lancea as the experiment materials,a filed experiment was conducted to study the effect of different nitrogen forms on plant growth.Different nitrogen forms were CK,amide nitrogen fertilizer (ANF),nitrate nitrogen fertilizer (NO-3-N) and ammonium nitrogen fertilizer (NH+4-N),in order to provide reference for nitrogen utilization efficiency in A.lancea.The results showed that application of nitrogen fertilizer increased green leaves number,stem diameter and plant biomass,accelerated absorption of N,P,K,and the increments of stem diameter,green leaves number and plant biomass under NO-3-N treatment were the highest,but proportion of plant dry matter to leaf and stem under NO-3-N treatment increased significantly more than the other treatments.In terms of nutrient absorption,total accumulation of N,P,K in leaf,stem and rhizome were both in the order of NO-3-N>NH+4-N>ANF>CK,the three nutrients accumulation in fibrous root was NO-3-N>ANF>NH+4-N>CK.In addition,ABE,AAE and AUE under NO-3-N treatment were significantly increased by 43.83%,106.10%,121.30%,and was 23.39%,74.51%,28.74% more than those under NH+4-N treatment.In conclusion,A.lancea was nitrate plant,so in cultivation application of nitrate nitrogen fertilizer was most suitable for promoting the dry matter accumulation,nutrient uptake and nitrogen utilization.
