| 中文摘要: |
| 在陕西省关中塿土区布置线辣椒、甘蓝、白菜、芹菜钾肥大田试验,研究不同蔬菜对钾肥的肥效反应。结果表明,增施钾肥可使蔬菜硝态氮含量降低11.8%～116.0%,维生素C含量增加0.4～147.4mg/kg;产量增加9.3%～33.8%;明显促进营养生长和生殖生长;400cm深土壤剖面硝态氮累积量减少22.7～48.0kg/hm2,尤其在80～220cm剖面减少最为明显。 |
| 英文摘要: |
| Field experiment was carried out on Lou soil area in Central Shaanxi province using capsicum, kale, cabbage and celery as indicating crops to study the response of different vegetable to K fertilizer. The results showed that K fertilizer cowd decrease the nitrate-N content of different vegetable by (11.8%) to 116.0%, and increase the vitamin C content by 0.4 mg/kg to 147.4 mg／kg, and increase yield of different vegetable by 9.3% to 33.8%. It also could promote both the vegetative growth and reproductive growth obviously and decrease the cumulative amount of nitrate-N in 400 cm soil profile of different vegetable by 22.7 kg/hm2 to 48 kg/hm2, which was especially remarkable in 80220 cm soil profile. |
