摘要
Abstract
In order to improve the pepper yield and fertilizer use efficiency ,under different fertilization levels(1 800 ,1 500 ,1 200 kg·hm‐2 ) ,the completely randomized trials was used to study the influence on mor‐phological index ,yield ,N ,P and K absorption of pepper shoots and agronomic efficiency of fertilizer with two kinds of slow‐release fertilizer formulations(A :N+ P2 O5 + K2 O=19% +10% +19% =48% ,B:N+ P2 O5 +K2O=17% +14% +17% =48% ) .The results showed that the application of slow‐release fertilizer had posi‐tive effects ,which yield ,shoots and fruits N ,P ,K contents were higher than CK treatment .Under the same fer‐tilizer conditions ,the pepper yield of application of slow‐release fertilizer A increased by 4 .72% than applica‐tion of slow‐release fertilizer B ;The N and P contents of A3 treatment were significantly higher than B3 treat‐ment .The K content of A2 treatment was significantly higher than B2 treatment about pepper shoots .The K contents of A1 and A3 treatment were significantly greater than B1 and B3 treatment about pepper fruits .The nitrogen and potash agronomic efficiency of A3 treatment was higher by 15 .04% than B3 treatment ,phosphate agronomic efficiency of the A1 ,A2 and A3 treatments were higher by 59 .08% ,51 .45% and 79 .99% than B1 , B2 and B3 treatments ,respectively .These results showed that the slow‐release fertilizer formulations A was more effective compared with the slow‐release fertilizer formulations B among the fertilizers in field trial and ensur production while improving the agronomic efficiency of fertilizer and it might have potential to a commer‐cial fertilizer .关键词
