一、“安信保水”牌保水剂的特点1.加入土壤以后能提高土壤对雨水、灌溉水的吸收能力,能快速吸收雨水、灌溉水并保存,当植物需要时,又缓慢释放。既能保证植物正常生长所需的水份,又能防止蒸发、渗漏、流失,使土壤长期保持湿润,并反复吸放水分缓慢供植物利用。2.改良土壤结构(团粒结构、透水性、透气性、热容量)。反复的收缩与膨胀给土壤造成大量的孔隙,提高了土

First, “security letter water” card water retaining agent features 1. After adding soil can improve soil rainwater, irrigation water absorption capacity, rapid absorption of rainwater, irrigation water and save, when the plant needs, and slowly release. It can not only ensure the water needed for normal growth of plants, but also prevent evaporation, leakage and loss, keep the soil moist for a long time, and slowly absorb and release water for plants to use slowly. 2. Improve the soil structure (aggregate structure, water permeability, air permeability, heat capacity). Repeated contraction and expansion of the soil caused a large number of pores, raising the soil
