松香甘油酯包膜肥料的制备及缓释性研究

Preparation of rosin-glyceride-coated fertilizer and study on its slow release property

首次以松香甘油酯为包膜材料、以石蜡为密封剂,制得了松香甘油酯包膜型缓释肥料,得到了最佳的包膜工艺。分别用淋溶法和水浸泡法研究了包膜肥料的缓释性,结果表明用石蜡密封后的包膜肥料缓释性显著提高。

The slow release rosin-glyceride-coated fertilizer,using rosin glyceride as coated material and paraffin wax as sealant,was prepared for the first time. And the best coated technics were obtained. The slow release property of coated fertilizer was studied by leaching and soaking method. The results indicated that the slow release property of rosin-glyceride-coated fertilizer sealed by paraffin wax was greatly improved.
