Embodiment 1

[0023] A thin-layer purple soil living soil water conservation tillage method, comprising the following steps:

[0024] (1) The slope with a gradient of 9° is divided into several tillage modules along the long slope direction, and a first no-tillage area of ​​23 cm is left between the adjacent tillage modules;

[0025] (2) In step (1), vertical rotary tillage machinery is used to carry out intermittent deep tillage in the tillage module. Under the action, it will naturally float up 10-15cm, the width of the wide ridge is 6m, and the width of the thin groove is 20cm;

[0026] (3) In step (2), the adjacent wide ridges are intermittently cultivated in the 45° oblique and 135° oblique cultivating directions; this method is used for continuous cultivating for 3 years.

Embodiment 2

[0028] A thin-layer purple soil living soil water conservation tillage method, comprising the following steps:

[0029] (1) The slope with a gradient of 16° is divided into several tillage modules along the long slope direction, and a first no-tillage area of ​​26 cm is left between adjacent tillage modules;

[0030] (2) In step (1), vertical rotary tillage machinery is used for intermittent deep tillage in the tillage module. Under the action, it naturally floats up to 10-15cm, the width of the wide ridge is 3m, and the width of the thin groove is 25cm;

[0031] (3) In step (2), the adjacent wide ridges are intermittently cultivated in the 45° oblique and 135° oblique cultivating directions; this method is used for continuous cultivating for 3 years.

Abstract

The invention discloses a thin-layer purple soil living soil water-retaining tillage method, comprising the following steps: dividing the slope surface into several tillage modules along the long slope direction, leaving a first no-tillage area of ​​20-30 cm between adjacent tillage modules; Intermittent deep plowing is carried out in the tillage module, and deep plowing forms wide ridges and the second no-tillage area. The width is 15-30cm; the adjacent wide ridges are intermittently cultivated in oblique 40-50° and 130-140° tillage directions. The method can effectively solve the problems existing in the existing tillage method that the soil layer is likely to become thinner day by day, the ability of soil to retain fertilizer and water is reduced, and the process of collecting soil without tillage is cumbersome.

Description

technical field [0001] The invention relates to the technical field of agricultural farming, in particular to a farming method for water conservation of thin-layer purple soil living soil. Background technique [0002] Purple soil is rich in mineral nutrients and has high natural fertility, but frequent tillage and unreasonable management have resulted in serious soil erosion on purple soil slopes, and soil degradation, especially the “shallow” characteristics of soil. and key elements to increase production and income. Serious soil erosion not only causes soil nutrient loss, soil fertility degradation, soil quality decline, and increased agricultural costs, but also causes soil gravelization and coarse ossification to increase year by year, becoming an important constraint on food growth and sustainable agricultural development. Soil and water loss is the carrier of non-point source pollutants. Nitrogen and phosphorus enter rivers along with soil and water loss, causing ri...
