Composite flower fertilizer containing bone meal

[0012] The present invention contains the compound flower fertilizer of bone meal, and its preparation method comprises the following steps:

[0013] Step 1. Select the clean livestock bones, poultry bones and fish bones in equal proportions, and grind them together into a uniform powder to obtain bone meal;

[0014] In step 2, the dried crop straws, the dried aquatic plants and the dried fruit leaves are selected according to an equal proportion, and ground together into a uniform powder to obtain plant ash; the crop straws are preferably wheat stalks, corn stalks, beans rod;

[0015] Step 3, any two of ammonium sulfate, urea, superphosphate or potassium sulfate, the two components are selected according to equal parts, according to bone meal 50%-60%, plant ash 10%-20%, inorganic fertilizer 30%-40% mass percentage, respectively, evenly mix with bone meal and plant ash, and then mix them all together to serve.

[0016] Example 1

[0017] Step 1. Select clean livestock bones, poultry bones and fish bones in equal proportions, and grind them together into a uniform powder to obtain bone meal;

[0018] Step 2, then select the dried wheat straw, the dried aquatic plants and the dried fruit leaves according to an equal proportion, and grind them together into a uniform powder to obtain plant ash;

[0019] Step 3. The two components of ammonium sulfate and superphosphate are selected in equal parts, and they are evenly mixed with bone meal and plant ash according to the mass percentage of bone meal 50%, plant ash 10%, and inorganic fertilizer 40%, and then all are mixed together. , and you're done.

[0020] Example 2

[0021] Step 1. Select clean livestock bones, poultry bones and fish bones in equal proportions, and grind them together into a uniform powder to obtain bone meal;

[0022] Step 2. Then, the dried corn stalks, the dried aquatic plants and the dried fruit leaves are selected according to an equal proportion, and ground together into a uniform powder to obtain plant ash;

[0023] Step 3. The two components of ammonium sulfate and urea are matched in equal parts, and they are evenly mixed with bone meal and plant ash according to the mass percentage of bone meal 55%, plant ash 10%, and inorganic fertilizer 35%, and then all are mixed together, that is, to make.
