Abstract

The invention provides a functional composite liquid fertilizer prepared by marine organisms and a preparation method of the functional composite liquid fertilizer. The functional composite liquid fertilizer contains the following components in percentage by weight: 6-10% of total N6, 2-4% of phosphorus pentoxide, 4-6% of potassium oxide, 2-6% of alginic acid, 3-6% of amino acid, 0.5-1.0% of copper, 0.8-1.6% of iron, 0.66-1.32% of manganese, 0.5-1.0% of zinc, 0.6-1.8% of molybdenum, 0.2-0.6% of boron, 0.5-1.5% of chlorine and 6-15% of sulfur. According to the functional composite liquid fertilizer, proceeding from the requirements in plant growth, various nutrients and plant growth regulating substances are enhanced, and the functions of preventing diseases, expelling insects, increasing production and the like are highlighted on the basis of nutrients.

Description

technical field [0001] The invention relates to a compound liquid fertilizer and a preparation method thereof, in particular to a new type of fertilizer that contains a variety of active components and nutrients of marine organisms, strengthens a variety of mineral nutrients and growth regulators to collect nutrients, prevent diseases, repel insects, A functional compound liquid fertilizer with four functions of increasing production and a preparation method of the functional compound liquid fertilizer. Background technique [0002] In the prior art, liquid fertilizers are sprayed on the leaves of plants based on amino acids to increase the protein content and output of plants. As the Chinese patents whose publication numbers are CN1069257A and CN1097184A, they prepare compound fertilizers containing amino acids with hair, hooves or skins containing keratin as raw materials. However, in the preparation methods disclosed in these two patent documents, the hydrolysis temperat...
