用不同的高分子添加剂将常用氮、磷化肥制成有机无机改性肥料,以花卉植物、粮食作物和牧草为供试材料进行肥效试验。结果表明,与等当量化肥相比,改性肥料使花卉植物长势旺盛、花色艳丽、花香浓郁;谷子、水稻分别增产23.3％和7.4～31.9％％。改性尿素比普通尿素还有较强的抗淋溶作用。
Using different macromolecular additives, nitrogen and phosphorus fertilizers were often used as organic and inorganic fertilizers. Fertilizers were tested on flower plants, grain crops and pasture as test materials. The results showed that compared with the equivalent amount of chemical fertilizers, the modified fertilizers made the plants grow vigorously with beautiful flowers and rich florals. The yields of millet and rice increased by 23.3% and 7.4 ~ 31.9% respectively. Modified urea urea than normal there is a strong anti-leaching effect.
