| 摘 要： | 以木薯品种辐选01和利达生物有机肥为材料,研究了生物有机肥对士壤速效氮、速效磷(P2O5)、速效钾(K2O)和木薯叶片全N、全P、全K含量的影响.试验结果表明:生物有机肥能明显提高土壤速效氮、速效磷(P2O5)、速效钾(K2O)的含量,同时在整个生长期中各生物有机肥处理木薯叶片全N、全P、全K含量均高于对照.

| Abstract: | The effects of bio-organic fertilizer on the hydrolyzable nitrogen,the available P2O5,the available K2O content of soil and the total N,the total P,the total K content of cassava leaf were studied in this experiment,of which the cassava variety Fuxuan 01 and bio-organic fertilizer produced by LIDA Company were used as materials.The results showed that applying bio-organic fertilizer could decrease the hydrolyzable nitrogen,the available P2O5,the available K2O content of soil obviously.The total N,the total ... |
