| 摘 要： | 采用调查分析、田间试验等方法,研究了旱作土壤条件下油用向日葵氮磷肥的吸肥特性和对氮磷肥的吸收规律。结果表明:不同厚度(0～20cm)和(20～40cm)的土壤对养分的吸收呈现动态的变化特点,施氮270.0kg/hm2时吸收氮素分别为47.5和35.7mg/kg,相差24.8%;油葵产量为2 604.0kg/hm2,施磷100.05kg/hm2时吸收磷素分别为28.4和21.5mg/kg,相差24.2%,油葵产量为3 199.5kg/hm2。 |

| Abstract: | By investigation and analysis,field experiment method,the dry soil conditions in sunflower oil absorption nitrogen phosphorus fertilizer characteristics and the absorption of nitrogen phosphorus fertilizer to rule of stuy were studied.The results showed that the different thickness(0~20 cm)and(20~40 cm) soil on the absorption of nutrients,dynamic characteristics of the changes of the present in the test conditions.N 270 kg/hm2 absorption nitrogen when were 47.5 mg/kg and 35.7 mg/kg,under 24.8%,crop yield of 2 604.0kg/hm2,100.05 kg/hm2 P fertilization absorbing phosphorus were 28.4 mg/kg and 21.5 mg/kg,under 24.2%,crop yield of 3 199.5 kg/hm2. |
