Spinach composite fertilizer

Abstract

The present invention discloses a spinach composite fertilizer, wherein the raw materials comprise, by weight, 20-30 parts of ammonium nitrate, 15-20 parts of a calcium magnesium phosphorus fertilizer, 15-22 parts of potassium chloride, 30-40 parts of plant ash, 15-20 parts of young grass, 20-30 parts of animal manure, 15-20 parts of animal hair, 1-2 parts of white sugar, 1-3 parts of brown sugar, 1-3 parts of an enzyme microorganism composting accelerator, 5-6 parts of attapulgite, 8-13 parts of lignite, 5-10 parts of phosphorite powder, 15-20 parts of bentonite, 10-13 parts of kaolin, 0.5-2 parts of enzyme microorganism, 10-13 parts of humus, 15-18 parts of calcium superphosphate, 6-8 parts of magnesium sulfate, 2-4 parts of zinc sulfate, 3-5 parts of copper sulfate, and 2-4 parts of sodium molybdate. The spinach composite fertilizer of the present invention meets the absorption law of the spinach on nutrients and has the high fertilizer utilization rate.

Description

technical field [0001] The invention relates to the technical field of spinach compound fertilizer, in particular to a compound fertilizer for spinach. Background technique [0002] A number of agricultural studies have pointed out that although chemical fertilizers supplement spinach with sufficient nutrients, they ignore the supply of organic matter. In the absence of sufficient organic matter in the soil where spinach is grown, it is difficult to form aggregates, and the adhesion between soil particles is weakened. Reduce the water retention capacity of the soil. When the soil does not have enough water, even if the fertilizer quality is high, it is not easy to release nutrients under favorable environmental conditions. If chemical fertilizers are used alone for a long time, the soil will have adverse effects on soil quality and the environment. . In addition, excessive application of chemical fertilizers will also have a serious impact on the environment. When excessive...

[0002] A number of agricultural studies have pointed out that although chemical fertilizers supplement spinach with sufficient nutrients, they ignore the supply of organic matter. In the absence of sufficient organic matter in the soil where spinach is grown, it is difficult to form aggregates, and the adhesion between soil particles is weakened. Reduce the water retention capacity of the soil. When the soil does not have enough water, even if the fertilizer quality is high, it is not easy to release nutrients under favorable environmental conditions. If chemical fertilizers are used alone for a long time, the soil will have adverse effects on soil quality and the environment.

In addition, excessive application of chemical fertilizers will also have a serious impact on the environment. When excessive chemical fertilizers are applied, the nutrients that have not been absorbed by the soil will be lost with the water, which cannot meet the requirements of the entire growth period of spinach. Absorption law, compound fertilizer with high fertilizer utilization rate has become a technical problem to be solved at present
