Process for preparing halophyte organic fertilizer using marine culture sludge

[0017] 1. Implementation steps

[0018] 1. Air-dry the mariculture sludge and sugar factory pond mud for later use.

[0019] 2. Determination of total nitrogen, alkaline nitrogen, total phosphorus, available phosphorus, Cl in air-dried samples - Concentration, pH value, conductivity and other indicators.

[0020] 3. Rinse and desalt the culture sludge. Control the water-to-soil ratio to 5:1, vibrate at 25°C for 5 minutes, filter with a Buchner funnel, and air-dry the rinsed sludge for later use.

[0021] 4. Collect the filtrate and measure the content of nitrogen and phosphorus. Determination of Cl in air-dried sludge after washing - Concentration, pH value, conductivity.

[0022] 5. Mix the air-dried mariculture sludge and sugar factory pond mud by 2:5 (mass ratio) after rinsing, and control the water content to 50%-60% (mass ratio), and stir and ventilate for 5-15 minutes every day. And ferment according to different treatments (as shown in the table below). Two repli...
