Embodiment 1
[0034] A method for drought resistance and flood drainage of dry slope land based on integrated cultivation of soil parent rock, comprising the following steps:
[0035] Step A: Use a small vertical ultra-deep rotary tiller to carry out integrated cultivation of the soil parent rock on the thin layer of mud shale purple soil, and use the upper layer crushing device to grind the soil layer 360°, and two adjacent upper layers of crushed soil Part of the uncultivated soil layer is left between the devices, and the hard soil ridge is formed in the lower layer of the soil. The mud shale is crushed by the lower parent rock crushing device, and the broken parent rock debris forms the parent rock debris in the lower part of the soil layer. dark trough;
[0036] Step B: adopt the local implementation method on the slope surface, carry out integrated cultivation of soil and rock at the middle and upper slope positions, adopt cross-slope cultivation at the middle and upper slope position...
