Abstract

本发明公开了一种橡胶控释肥及其制备方法。该控释肥是将两种不同释放期的反应成膜包膜尿素、尿素、磷酸二铵、氯化钾和硫酸镁等组分复配制得。本发明的橡胶专用控释肥年生长周期只需要施一次肥,能持续同步供应橡胶所需的养分,满足橡胶年生长期中对氮磷钾三要素的需要,并解决了单独使用控释肥成本高的问题。明显提高了施肥效果,减少了施肥次数,省工省力,降低了生产成本,提高了经济效益,同时添加中微量元素镁,提高胶水干含量。
The invention discloses a rubber controlled release fertilizer and a preparation method thereof. The controlled release fertilizer is prepared by compounding such ingredients as two kinds of reaction film coated urea with different release stages, urea, diammonium phosphate, potassium chloride and magnesium sulfate,. The special rubber controlled release fertilizer disclosed by the invention only needs to be fertilized once within an annual growth cycle to continuously and synchronously supply nutrients necessary for the rubber, satisfy the demand of the rubber on three elements of nitrogen, phosphorus and potassium in the annual growth period and solve the problem of high cost of singly utilizing the controlled release fertilizer. The rubber controlled release fertilizer has the advantages of obviously improving the fertilization effect, reducing fertilization times, saving work, saving labor, lowering the production cost, improving the economic benefit, while adding trace element magnesium and increasing the dry content of glue.
