Water and soil loss preventing and control method for hawthorn tree and codonopsis pilosula three-dimensional cultivation

Abstract

The invention discloses a water and soil loss preventing and control method for hawthorn tree and codonopsis pilosula three-dimensional cultivation. The method comprises the following steps of (1) land selection and land preparation: selecting river valley regions with mild climate, deep and thick soil layer and flat terrain; (2) ridge forming: forming ridges; flatly raking ridge gaps to form planting lines; then; cutting off ridge surfaces to form ladder ridges; cutting the gaps to form passages; using a black shading net for covering the ladder ridges; (3) fertilizer supplementation: applying rotten straw fertilizer prepared in the step (1) into the planting lines; performing sufficient field drying for 7 to 15 days; (4) hawthorn tree planting; (5) codonopsis pilosula planting; (6) fieldmanagement. The three-dimensional cultivation mode of interplanting the hawthorn tree and codonopsis pilosula is used; the vegetation cover rate in the unit area is greatly increased; important effects are achieved on water and soil loss prevention; the biological study properties of the hawthorn tree and codonopsis pilosula are sufficiently utilized; the relatively good growth of the hawthorn tree and codonopsis pilosula can be ensured; the two staggered green windproof and sand fixing barriers (the upper barrier and the lower barrier) can be formed; the water and the soil can be maintainedto the maximum degree; the soil fertility is maintained.

Description

technical field [0001] The invention belongs to the technical field of soil and water conservation, and in particular relates to a method for preventing and controlling soil erosion by three-dimensional cultivation of hawthorn and Codonopsis. Background technique [0002] Hawthorn is a deciduous tree of the genus Hawthorn in the Rosaceae family. It is mostly grown on the edge of hillside forests or in bushes. It has strong adaptability and likes a cool and humid environment. It is resistant to cold and high temperature, and can grow between -36-43 °C. ; But when there is too much water, the branches and leaves are easy to grow leggy. The soil requirements are not strict, but it grows well in slightly acidic sandy loam with deep soil layer, fertile texture, loose and well-drained soil. Its fruit is spherical, dark red, with small spots, sour in taste, can be eaten raw or made as a fruit cake, and can be used as medicine after drying. It is a unique tree species for both medi...

Problems solved by technology

However, since this method is only for harvesting Codonopsis pilosula, and does not make full use of the weeds in the field, it not only leads to the waste of natural fertilizers, but also increases the time for manual cleaning.

In addition, this method requires a lot of work to readjust the humus soil in the field, which is time-consuming and labor-intensive, and the soil fertility cannot meet the needs of high fertility, especially the low content of nitrogen fertilizer, which is not conducive to the growth of plants.

More importantly, this method re-lays the field with humus, which is easy to cause soil erosion in the Gaofengsha area, which not only damages the environment, but also reduces soil fertility
