氮磷钾肥料对天鹰椒养分吸收量及干物质产量的影响

Effect of N,P and K Fertilizer on Nurtrient Uptake and Dry Matter Yield of Cluster Redpepper

天鹰椒施用氮肥 ,增加了干物质中N ,Mg的百分含量 ,但减少了P和K的百分含量 ;施N情况下 ,N ,P ,Ca,Mg的吸收总量增加。施用磷肥 ,增加了干物质中P的百分含量 ,减少了Ca ,Mg的百分含量 ;N ,P ,K ,Ca的吸收总量增加 ,Mg的吸收总量减少。施用钾肥 ,增加了干物质中K的百分含量 ,减少了Ca ,Mg的百分含量 ,K ,P的吸收总量增加 ,N ,Ca 。

With N application,the percentage concentration of N and Mg in the dry matter of cluster redpepper increased,while the percentage concentration of P and K decreased.N application increased the total uptake amount of N,P,K,Ca and Mg.By applying P fertilizer,the percentage concentration of P in the dry matter increased while the percentage concentration of Ca and Mg decreased.P application increased the total uptake amount of N,P,K,and Ca,but suppressed the uptake of Mg.Under the condition of K application,K percentage concentration in the dry matter increased, while Ca and Mg decreased. K fertilizer application enhanced the total uptake amount of K and P,but decreased the uptake amount of N,Ca and Mg.
