摘要

Using 60Co-? ray, the self-made water-keeping agent which was resistant to degradation was prepared, and then applied to drought resistance cultivation of sweet potato. The experimental results showed that when dosage of water-keeping agent reached 4 g/plant, the yield can increase by 60.0%. Therefore, the self-made water-keeping agent has effects of drought resistance and yield increasing.%采用60Co-γ射线自制耐降解的保水剂,并应用于甘薯抗旱栽培.试验结果表明:当保水剂用量达到4g/蔸时,增产幅度可达到60.0％,自制保水剂可起到抗旱增效的作用.
