针对山东沙质海岸土壤保水性能差的特点 ,进行了施加高分子吸水剂的试验。结果表明 ,施用高分子吸水剂能显著增强土壤的吸水和持水能力 ,提高黑松造林成活率。高分子吸水剂施入量以 10～ 2 0g/株为宜
According to the characteristics of poor soil water retention capacity of Shandong sandy coast, the experiment of applying polymer absorbent was carried out. The results showed that the application of polymer water-absorbing agent can significantly enhance the soil water absorption and water holding capacity and improve the survival rate of Korean pine. Polymer water-absorbing agent applied to 10 ~ 20g / strain is appropriate
