| 中文摘要: |
| BP保水剂的实验室保水试验及其在宁南山区的生产应用实践表明,BP保水剂对农作物有储存水分和提供养料、提高产量的作用。使用保水剂后,地膜春小麦、地膜玉米、豌豆、土豆的土壤含水率分别提高8.86%、11.44%、7.95%、12.13%,产量分别提高了10.79%、12.19%、8.87%、8.25%。BP保水剂具有明显的抗旱增产作用。 |
| 英文摘要: |
| The experiments conducted in the mountainous region of south Ningxia showed that BP aquasorb was effective in conserving soil moisture, improving nutrient condition and increasing crop yield. By applying BP aquasorb to the field of wheat, corn, pea and potato, the soil moisture content was raised by 7.95%12.13%, and the yield was increased by 8.25%12.19%. Therefore, BP aquasorb is an effective way to resist drought and to increase crop production in arid areas. |
