Novel efficient fertilizer and preparation method thereof

Abstract

The invention discloses novel efficient fertilizer. According to the formula, the novel efficient fertilizer comprises the following raw materials in parts: 20-35 parts of nitrogen, 10-25 parts of phosphorus, 15-30 parts of potassium, 1 part of calcium, 1 part of magnesium, 2 parts of sulphur, 0.009 part of iron, 0.14 part of manganese, 0.2 part of zinc, 0.0005 part of molybdenum, 0.5 part of copper, 1 part of silicon, 0.1 part of sodium, 0.0005 part of selenium, 0.05 part of boron, 3 parts of humic acid, 2 parts of amino acid, 1 part of alginic acid, 1 part of chitosan, 2 parts of a chelating agent, 1 part of vitamins, 5 parts of a fertilizer synergist, 3 parts of a slow-release agent and 3 parts of a filling agent. The novel efficient fertilizer is comprehensively nutritional, that is, the macroelements, medium elements, microelements and plant-derived biologically active substances meet the requirements for the growth and development of plants; the fertilizer effect lasts for a long time, and the novel efficient fertilizer has a slow-release function, so that the utilization ratio of the novel efficient fertilizer is high, and the fertilizer application frequency, the labor intensity, and the production cost of agricultural products are reduced.

Description

technical field [0001] The invention belongs to the field of bioengineering, and in particular relates to a novel high-efficiency fertilizer and a preparation method thereof. Background technique [0002] Chemical fertilizers are fertilizers made by chemical and (or) physical methods that contain one or more nutrients needed for crop growth, which can provide one or more nutrients essential to plants in the process of agricultural production and improve soil properties. , Improving the level of soil fertility is one of the material foundations of agricultural production. However, the fertilizers currently used and sold on the market are too single in nutrients, have low fertilizer utilization rates, short fertilizer effects, and too few national standards for agricultural fertilizers, which cannot meet market needs. In addition, various standard fertilizers also split the nutrients needed by plants and need to be applied separately. Such multiple fertilization greatly incre...

Problems solved by technology

But currently the fertilizers used and sold on the market have too single nutrient composition, low fertilizer utilization rate, short fertilizer effect, and too few national standards for agricultural fertilizers, which cannot meet the needs of the market.

In addition, various standard fertilizers also split the nutrients needed by plants and need to be applied separately. Such multiple fertilization greatly increases labor and production costs.
