1.应选择容易被叶片吸收的肥料,常用的有尿素、过磷酸钙、硫酸钾、磷酸二氢钾、硫酸镁、硼砂、硝酸铵、磷酸铵等。 2.肥液浓度一般以尿素0.3％～0.5％,过磷酸钙1％～3％,硫酸钾0.5％,磷酸二氢钾0.3％,硫酸镁0.2％～0.3％,硼砂0.1％,硝酸铵0.2％,磷酸铵0.5％～1％为宜。 3.可在肥液中添加适量的洗衣粉等活性剂,降低表现张力,提 1. Should be easy to be absorbed by leaves of fertilizer, commonly used urea, superphosphate, potassium sulfate, potassium dihydrogen phosphate, magnesium sulfate, borax, ammonium nitrate, ammonium phosphate and so on. 2. Fertilizer concentration generally urea 0.3% to 0.5%, superphosphate 1% to 3%, potassium sulfate 0.5%, potassium dihydrogen phosphate 0.3%, magnesium sulfate 0.2% to 0.3%, borax 0.1%, ammonium nitrate 0.2 %, 0.5% ~ 1% ammonium phosphate is appropriate. 3. Can be added to the appropriate amount of manure fluid detergent and other active agents to reduce the performance of tension, mention
