Problems solved by technology

[0005] Aiming at the problems in the prior art that the calcareous purple soil layer is shallow, the soil moisture capacity is small, the ability of water retention and drought resistance is poor, and the seasonal distribution of rainwater is uneven, which leads to the restriction of the agricultural production of the dry slope land caused by the drought in the early stage and the flood in the later stage, the present invention provides a The device and method for anti-drought and flood drainage of dry slope land with integrated farming, the purpose of which is to realize the physical improvement of dry slope land and improve the capacity of water conservation, storage and drainage

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...

Abstract

The invention discloses a drought-resisting and flood-draining method and device for a dry sloping field based on soil and mother rock integrated cultivation, and belongs to the technical field of agricultural production. The method solves the problems that in the prior art, due to the fact that a soil layer is light and thin, the soil moisture capacity is small, the water retention and drought resistance capacity is poor, and rainwater seasonal distribution is uneven, early-stage drought and later-stage waterlogging restrict agricultural production of the calcareous purple soil drought slope land, and comprises the steps that soil and mother rock integrated cultivation is carried out on thin-layer shale purple soil; wherein a part of uncultivated soil layer is reserved between every two adjacent upper-layer soil crushing devices, a soil hard blocking ridge is formed on the lower layer of the soil, shale is crushed through the lower-layer mother rock crushing device, and the crushed mother rock debris forms a mother rock debris covered channel on the lower portion of the soil layer, so that soil and mother rock integrated cultivation is achieved, and the soil and mother rock integrated cultivation efficiency is improved. The technical effects of improving the drought resistance, enhancing the flood drainage capacity, collecting water in all directions of runoff and interflow and optimizing the rainwater utilization rate are achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a drought-resistant and flood-draining method and device for dry slope land based on integrated cultivation of soil parent rock. Background technique [0002] The purple soil area in Sichuan has a large population density, high reclamation index, intense cultivation, and serious soil erosion, resulting in shallow soil layers on slopes, especially on upslopes. The water retention capacity is poor, which does not match the potential of agricultural production increase. In the dry slopes of purple soil with little irrigation conditions, the shortage of soil moisture has become the main limiting factor of agricultural production. There are more than 3 million mu of dry land distributed on higher platforms in the purple soil area of ​​Sichuan. Their advantages are better light and heat conditions, rich nutrients, and moderate texture. However, these advan...
