保水剂是国际上近20年发展起来的抗旱节水的高吸水性树脂,能吸收自身重量成百倍的水供植物使用。我们在黄土半干旱地区进行了3年果树栽培试验,发现拌土以干土重0.1％比例施用,产出投入比达最佳,苗木移栽成活率在90％。生长期内,饱和凝胶10％～15％拌土,可连续抗旱40多天,增产25％～30％。

Water-retaining agent is developed in the world for nearly 20 years, water-saving drought-resistant super absorbent resin, can absorb its own weight into water for plants to use. We conducted a three-year fruit-planting experiment in the semi-arid loess region. We found that the mixed soil is applied at a rate of 0.1% of the dry soil weight, with the best ratio of output to output. The survival rate of transplanting seedlings is 90%. During the growing season, saturated gel 10% ~ 15% mixed soil, continuous drought more than 40 days, an increase of 25% to 30%.
