合成了新型脲醛液体缓释肥，并在大白菜、茄子和西红柿上开展了脲醛液体缓释肥应用肥效实验。研究结果表明，施用脲醛缓释肥可以提高大白菜总产量和单颗重，产量增幅为10.66%；显著提高茄子产量和株高，产量增幅为25.93%，平均株高增加6.85 cm；显著提高西红柿产量和株高，产量增幅为40.70%，平均株高增加11.88 cm；同时可以减少施肥次数，提高肥料利用率。

A new type of liquid urea-formaldehyde slow-release fertilizer is synthesized, and its effect is evaluated on Chinese cabbage, eggplant and tomato.Results indicate that the new liquid urea-formaldehyde slow-release fertilizer can significantly increase the yield of Chinese cabbage, eggplant and tomato, and improve the plant height, fruit weight and other agronomic traits.The new liquid urea-formaldehyde slow-release fertilizer can increase the total yield and single head weight of Chinese cabbage by 10.66%, increase the yield and average plant height of eggplant by 25.93% and 6.85 cm.respectively, and the yield and plant height of tomato by 40.70% and 11.88 cm, respectively.Moreover, the use of urea-formaldehyde slow-release fertilizer can reduce the number of fertilization and improve the utilization rate of fertilizer.
