Embodiment 1
[0048] A microporous sludge water-retaining nutrient polymer, which is composed of two parts: an inner layer of high-efficiency water-retaining humus nutrient base liquid and an outer layer of microporous sludge solidified block. Carboxymethyl cellulose and sodium carboxymethyl cellulose are grafted and copolymerized in an aqueous solution. The outer microporous sludge solidification block is 120mm long, 120mm wide, and 120mm high. The central area is reserved for a length of 70mm, a width of 70mm, and a height of 70mm. space, the inner layer of high-efficiency water-retaining humus nutrient base solution is located in the central area of the outer layer of microporous sludge solidification block. Bubble holes with a diameter of 1.0 mm are distributed on the outer microporous sludge solidification block, and the holes with a diameter of 1.0 mm are mainly in the area close to the inner layer of high-efficiency water-retaining humus nutrient base liquid, and away from the inner...
