Organic long-lasting slow-released fertilizer and manufacturing method

Abstract

The invention discloses an organic long-lasting slow-released fertilizer and a manufacturing method. The organic long-lasting slow-released fertilizer comprises the following components in parts by weight: 85-83 parts of a nitrogenous fertilizer, 7-5 parts of diethylenetriamine, 7-5 parts of humic acid, 4-1 parts of modified starch, 3-5 parts of polyving akohol and 2-1 parts of diethyl aminoethyl hexanoate DA-6.

Description

technical field [0001] The invention relates to an organic long-acting slow-release fertilizer and a preparation method thereof. Background technique [0002] In view of the long-term focus of the world's attention, such as low nitrogen utilization rate leading to environmental pollution and harm to human health, the current land has been extensively applied with nitrogen, phosphorus and potassium fertilizers for many years, and crop yields have continued to increase, resulting in calcium, magnesium, sulfur and trace elements in the soil. Deficiency, has become a limiting factor in increasing crop yields. Contents of the invention [0003] The object of the present invention is to provide an organic long-acting slow-release fertilizer capable of improving soil and increasing crop yield and a preparation method thereof. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] An organic long-acting slow-release fertilizer, its composition comprise...
