specific Embodiment approach 1
[0018] Specific implementation mode 1: The improvement method of this implementation mode to rapidly increase the organic matter of paddy field soil in saline-alkali land is implemented according to the following steps:
[0019] 1. Use urban domestic sludge and livestock and poultry manure as organic materials, and obtain harmless organic materials through harmless treatment. After fully mixing the harmless organic materials and calcium ion displacing agent, dry and granulate, get modifiers;
[0020] 2. According to the amount of 2-3 tons per mu of paddy field, spread the modifier evenly on the surface of the flattened paddy field, use a rotary tiller to plow the surface soil with a thickness of 10-15cm for mixing, and then inject water into the paddy field to a depth of 5-8cm. Rake the ground with a pulper, stir the surface mud evenly, settle and drain while injecting new water at the same time to wash the salt and drain the alkali, repeat the salt washing and draining the al...
specific Embodiment approach 2
[0022] Embodiment 2: This embodiment differs from Embodiment 1 in that the detoxification treatment described in step 1 is high-temperature sterilization. Other steps and parameters are the same as those in Embodiment 1.
specific Embodiment approach 3
[0023] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the mass content of the organic matter in the harmless organic material in Step 1 is 25%-30%. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.
