将高分子吸水剂生物胶及其它药物配成３２种不同浓度的药液，造林前对苗木进行蘸根处理。通过３年试验，从中筛选出成本低且可大幅度提高干旱地造林成活率的ＨＲＣ保苗剂、生物胶等药物，避免或减少了由于重造或补植所造成的损失，有效地解决了干旱地造林成活率较低的难题。
Polymer absorbent polymer and other drugs dubbed 32 different concentrations of liquid, before planting seedlings dipping treatment. After three years of experiments, HRC seedling-protecting agents such as HRC, bio-gum and other drugs with low cost and greatly improved survival rate in arid land can be selected to avoid or reduce the losses caused by rebuilding or replanting, thus effectively solving the problems of drought Afforestation survival rate is low problem.
