摘要： This disclosure relates to water-absorbing and slow/controlled release fertilizer, in particular to a water-absorbing and water-retaining multi-nutrient biodegradable polymeric slow/controlled release fertilizer having a semi-interpenetrating network structure, and preparation methods thereof. The method can comprises the steps of: reacting formaldehyde with urea to obtain a hydroxymethyl urea solution; adding acrylic acid and acrylamide monomers into another reactor, and adding a KOH solution to adjust the neutralization degree of acrylic acid, then adding one of inorganic clay, pretreated crop straw or cellulose, then adding initiator, monopotassium phosphate and the prepared hydroxymethyl urea solution sequentially; allowing to react at temperature after being mixed uniformly to obtain a viscous product; and granulating the viscous product and oven drying the same to obtain the fertilizer. The fertilizer prepared according to the present invention has strong water-absorbing and water-retaining capacity, and an excellent slow release performance for nitrogen, phosphorus and potassium contained as nutrients.

摘要： A composition comprising an ampholytic copolymer or terpolymer and a non ionic surfactant is shown useful in soil treatment, especially moisture and nutrient retention. The highly surface active compositions described herein self-assemble onto root zone plant surfaces and near-root soil, forming a moisture barrier that still permits root growth and oxygen flow. The inventive compositions increases the wettability of the soil allowing the soil to better absorb water at the beneficial root zone, and release it, along with essential nutrients, to the plant root structure. By targeting moisture retention in the root zone, the polymer decreases the migration potential to the root zone, producing higher irrigation efficiency for optimal plant growth with lower treatment levels. Different dilutions of the composition determine the final settling location of the composition, and the formation of the barrier. The compositions may be applied through known means, such as an irrigation system.
摘要翻译：显示包含两性共聚物或三元共聚物和非离子表面活性剂的组合物用于土壤处理，特别是水分和养分保留。本文所述的高表面活性组合物自组装在根区植物表面和近根土壤上，形成仍然允许根生长和氧气流动的水分屏障。本发明的组合物增加了土壤的润湿性，允许土壤更好地吸收有益根区的水，并将其与必需营养物质一起释放到植物根结构上。通过在根区域中保持水分，聚合物降低了根区的迁移潜力，产生更高的灌溉效率，使植物生长最佳，处理水平较低。组合物的不同稀释度决定了组合物的最终沉降位置和形成屏障。组合物可以通过已知方法施用，例如灌溉系统。
