摘要
通过溶水和淋溶试验研究了几种包膜肥料的缓释效应,以筛选无污染、能提高肥利用率的包膜材料。结果表明,用L做粘结剂,D包膜的半数溶水时间最长,为2h50min,混合材料包膜最长的为用L做粘结剂,D、J混合包膜,溶水时间为9h。从淋溶试验来看,4种矿物包膜肥料都提高了肥料利用率,其中F的效果最好。
The release effect of several different kinds of coated fertilizers was studied by dissolution and leaching experiment. The results showed that the longest dissolution time was 2 h 50 min,when it was mixed by L and D. Using two different material,the longest time was 9 h,it was mixed by D and J. From the leaching effect,the four coated fertilizers improved fertilizer utilization rate,F was the best.
