Sugarcane fertilizer additive and preparation method thereof

Abstract

The invention discloses a sugarcane fertilizer additive, which comprises the following raw materials: 6-10 parts by weight of trace elements; 6-18 parts by weight of humic acid chelated rare earth; 3-6 parts by weight of slow-release agent ; 4-6 parts by weight of water-retaining agent; 8-15 parts by weight of organic matter. The production method is as follows: firstly, humic acid and rare earth chloride or rare earth oxide are used for chelation reaction to prepare humic acid chelated rare earth, and then various materials are added, mixed uniformly, dried and pulverized. The fertilizer additive of the present invention is mixed evenly with chemical fertilizers and applied; the general addition amount is 5-7%; the addition amount in sugarcane base fertilizer is 5%, and the addition amount in sugarcane topdressing fertilizer is 7%. The fertilizer additive of the invention can improve the utilization rate of sugarcane to chemical fertilizers, increase the plant height and stem diameter of sugarcane, and increase the yield.
