specific Embodiment approach 1
[0018] Specific embodiment 1: In this embodiment, a kind of carbonate-type rice field organic compound special improver is composed of 50%~60% furfural slag, 5%~12% furnace ash, 30%~35% livestock and poultry manure according to the mass percentage and 3% to 7% lignite.
[0019] The organic compound special improver for carbonate type paddy field of the present embodiment has an organic matter content (dry basis) of 60% to 70%, which can increase the soil organic matter content, fertilize soil fertility, and have a good effect in improving soil. It is easy to use, and is convenient for large-area and mechanized operation.
[0020] Table 1 shows the usage amount of the carbonate-type paddy field organic compound special improver according to different pH values of the present embodiment.
[0021] The application time of the carbonate-type paddy field organic compound special improver of this embodiment is to combine with paddy paddy fields to be applied together with chemical...
specific Embodiment approach 2
[0024] Specific embodiment two: What this embodiment differs from specific embodiment one is that the organic compound special improver for carbonate type paddy field is made up of 53%~58% furfural slag, 6%~10% furnace ash slag, 31% by mass percentage ~34% livestock and poultry manure and 4%~6% lignite. Other parameters are the same as in the first embodiment.
specific Embodiment approach 3
