Embodiment Construction

[0014] The measures of the present invention are: according to the nutritional requirements of different crops, oyster shell powder and shell powder, fermented fish meal fertilizer, nitrogen, phosphorus and potassium components of chemical fertilizers are allocated, the materials are mixed and stirred evenly and the water content is adjusted to 40-50 %, the pH value is 6-7, and then add microbial flora to ferment, control the temperature at 40-65 ° C, and the time is 3-5 days, so that the activated calcium powder can absorb various nutrients in a balanced manner. Finally, after air-drying or drying, powder fertilizer or granular fertilizer is made according to conventional methods.

[0015] The fertilizer is prepared from the following raw materials in percentage by weight:

[0016] Oyster shell meal and shell meal 20-70%

[0017] Fermented fishmeal fertilizer 20-70%

[0018] Nitrogen, Phosphorus, Potassium 10-38% of chemical fertilizer

[0019] Magnesium, sulfur, boron, zi...

Abstract

The invention discloses a multipurpose fertilizer with marine organism calcium. A preparation method for the multipurpose fertilizer comprises the following steps of: blending oyster shell powder, shell powder, a fermented fish meal fertilizer and nitrogen, phosphorus and potassium components of a chemical fertilizer according to requirements of different crops on nutrition, mixing and stirring the raw materials uniformly, and regulating to ensure the moisture is between 40 and 50 percent and the pH value is between 6 and 7; adding microbial bacterial colonies, and fermenting at the temperature of between 40 and 65 DEG C for 3 to 5 days to ensure that activated calcium powder adsorbs various nutrients in a balanced way; and air drying or drying to prepare a powder fertilizer or a granular fertilizer according to the conventional method. The multipurpose fertilizer has the advantages of simple preparation method, abundant, comprehensive and balanced nutrition required by plants, water retention and fertility preservation, and is suitable for the growth of various plants.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to the preparation of a marine biological calcium multi-element fertilizer. Background technique [0002] For a long time, the fertilizers applied to crops are mainly fertilizers containing nitrogen, phosphorus and potassium, which are called "macroelement fertilizers", while "medium and microelement" fertilizers containing calcium, magnesium and sulfur are often ignored. In fact, the content in plant stem cells (except hydrogen, oxygen and carbon): 1.5% nitrogen, 1.0% potassium, 0.5% calcium, 0.2% magnesium, 0.2% phosphorus and 0.1% sulfur. It can be seen that plants have a relatively high demand for calcium, which is 2.5 times higher than phosphorus. [0003] my country is a large agricultural country, the area of ​​agricultural arable land is shrinking continuously, and the rate of agricultural output is low, especially in coastal areas, where there are problems of soil aging, drought...
