- 摘要:
- 为提高辣椒产量和肥料利用率，采用完全随机试验，在不同施肥水平下（1 800、1 500、1 200 kg·hm-2），比较了2种缓释肥配方（A：N+P2O5+K2O=19%+10%+19%=48%、B：N+P2O5+K2O=17%+14%+17%=48%）对辣椒形态指标、产量、辣椒地上部对氮、磷、钾的吸收和肥料农学利用率的影响。结果表明：缓释肥处理的辣椒长势好，其产量、地上部和果实中氮、磷、钾含量均大于对照处理(CK)。在相同施肥水平下，缓释肥A处理的辣椒产量比缓释肥B处理平均高4.72%；在辣椒地上部，A3处理氮、磷含量显著大于B3处理，A2处理钾含量显著大于B2处理；在辣椒果实中，A1和A3处理钾含量显著大于B1和B3处理；A3处理的氮肥、钾肥农学利用率均比B3处理高15.04%，A1、A2和A3处理的磷肥农学利用率比B1、B2、B3处理的分别高59.08%、51.45%、79.99%。与缓释肥配方B相比，缓释肥配方A在辣椒生产上显得更有优势，在保证产量的同时提高了肥料农学利用率，具有一定的应用前景。
- 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 morphological index,yield,N,P and K absorption of pepper shoots and agronomic efficiency of fertilizer with two kinds of slowrelease fertilizer formulations（A：N+P2O5+K2O=19%+10%+19%=48%,B：N+P2O5+K2O=17%+14%+17%=48%）.The results showed that the application of slowrelease fertilizer had positive effects,which yield,shoots and fruits N,P,K contents were higher than CK treatment.Under the same fertilizer conditions,the pepper yield of application of slowrelease fertilizer A increased by 4.72% than application of slowrelease fertilizer B; The N and P contents of A3 treatment were significantly higher than B3 treatment.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 slowrelease fertilizer formulations A was more effective compared with the slowrelease 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 commercial fertilizer.
