为了提高土壤的肥力和防止雨水和风对土壤的浸蚀,采用人造土壤改良剂,改善土壤物理结构。通常,改良剂系水溶性合成聚合物,多半是丙烯系列,称为(系商品名)。作为土壤改良剂是非常有效的,但由于工业生产丙烯类聚合物的可能性受到限制,所以不能得到广泛地应用。到目前为止,由于缺少有效、可行的改良剂,在实践中尚未实施人工改良土壤。因此,寻找新型土壤改良剂是具有国民经济意义的一个重要任务。
In order to improve soil fertility and prevent soil erosion by rain and wind, artificial soil amendments are used to improve the physical structure of the soil. Normally, the modifier is a water-soluble synthetic polymer, which is mostly a propylene series and is referred to as (trade name). It is very effective as a soil improving agent, but it can not be widely used due to its limited possibility of producing propylene polymers industrially. So far, due to the lack of effective and viable improvers, no artificial soil improvement has been implemented in practice. Therefore, looking for a new soil conditioner is an important task of national economic significance.
