Embodiment 1
[0024] The improving agent, calculated by weight percentage of dry weight, is 65% of chicken manure, 30% of phosphogypsum, and 5% of zeolite powder.
[0025] Before the ratio of raw materials, collect 5 samples of livestock manure and phosphogypsum respectively according to the multi-point sampling method, weigh 5-10 grams of each sample in an aluminum box, put it in a drying oven at 105°C-110°C After drying for 6-8 hours, calculate the water content by weight of the sample. The formula for calculating the dry weight of the sample is as follows:
[0026]
[0027] The water content of the sample weight is the average value of the results of 5 repeated measurements.
[0028] The actual weight of the sample taken should be the weight after deducting the water content. For example, the water content of a fresh chicken manure is 60%. The weight of is 65(1+60%)=104 kg.
[0029] Improver preparation method:
[0030] According to the weight percentage of dry weight, mix 65% chi...
Embodiment 2
[0034] The difference from Embodiment 1 is that this embodiment can be used in factory production. Mix the chicken manure, phosphogypsum, and zeolite powder in proportion in Example 1, spread it on the ground and dry it in the shade for 3-5 days, then put it into the drying equipment and dry it at about 120-150°C, and put it into the mixer Stir evenly in the medium, pass through a 40-80 mesh sieve, and get the finished product after bagging.
Embodiment 3
[0036] The difference from Example 1 is that the weight percentages of the dry weights of the three raw materials are different.
