| 摘 要： | 为辣椒进行科学平衡施肥及辣椒优质高产栽培,以海椒4号为材料,研究了不同形态氮肥对辣椒产量的影响,同时测定了辣椒对不同形态氮肥的利用效率。试验结果表明,当有机氮肥、铵态氮和硝态氮比例为0.21∶0.1∶0.69时,辣椒产量最高,氮肥农学利用率高达22.5 kg/kg。

| Abstract: | The effect of nitrogen form on the growth of capsicum was studied,using Haijiao No.4 as material.The results showed that organic nitrogen∶ammonium∶nitrate ratio of 0.21∶0.1∶0.69,capsicum reached the highest yield;N use efficiency than the conventional treatment was 7.2 percentage points higher;nitrogen agronomic efficiency of 22.5 kg/kg. |
