Description

Slope soil preparation method for planting of mountain tung tree

Technical Field

The invention relates to the field of tung tree planting, in particular to a slope land preparation method for mountain tung tree planting.

Background

The tung tree planting has the current comparative benefit which is not high, so the tung tree planting is basically planted in the mountain land. Aiming at the defects that the existing mountain tung tree planting has the defects that as shown in figure 1, the mountain planting is directly dug to be planted after a pit is dug, the nutrition is insufficient, after a planting hole is dug out, a seedling is planted in the planting hole, the root system in the hole is basically raw soil with a downward binding approach, the raw soil has poor nutrition, the nutrition is difficult to guarantee, and the seedling grows thin and small; the digger is also seen to push the terraced land, but the surface soil is often pushed to the edge of the terraced land and planted on the exposed raw soil on the flat terraced land, so that the digger is very poor in nutrition and has no catchment ditch. If the base fertilizer is applied manually, the cost is inevitably increased, and the economic benefit is reduced; the slope planting meets drought seasons, and water and soil are easy to lose; after the tung tree is mature, the tung tree fruits can fall down naturally, if the tung tree fruits are not in the soil, the tung tree fruits roll to a far downhill on a natural slope, and a large amount of fruits are not easy to find, so that the economic loss is caused.

Disclosure of Invention

The invention aims to solve the technical problem of providing a slope soil preparation method for planting a mountain tung tree to solve the defects in the prior art.

In order to achieve the above purpose, the present invention provides the following technical solutions: a method for preparing soil on a slope surface for planting tung tree in a mountain land comprises the steps of digging an upward slope position of the slope surface downwards to form a water collecting ditch, piling soil dug out from the upward slope position at a downward slope position, and superposing the upward slope position and surface soil of the downward slope position to form a planting ridge.

Preferably, the depth of the water collecting ditch is 30-50 cm, and the width of the water collecting ditch is 60-90 cm.

Preferably, when the slope angle is less than 30 degrees, a catchment ditch is basically formed along the contour line of the hillside, the dug soil is stacked below the ditch to form planting stalks, the slope is trimmed into a plurality of horizontal steps from top to bottom and is connected up and down to form steps, and the planting ridge of each step is an aleurites fordii planting zone.

The beneficial effect of adopting above technical scheme is: the invention has the functions of saving fertilizer, controlling grass, ensuring water supply, remarkably promoting growth and facilitating the harvest of tung tree fruits, and has the advantages of simplicity, practicability and strong practicability.

Detailed Description

Preferred embodiments of the present invention are described in detail below.

The invention is explained by combining the figures 2-4, and the slope land preparation method for planting the tung tree in the mountainous region digs the uphill position of the slope downwards to form a water collecting channel, the surface soil part dug out from the uphill position is piled up at the downhill position, and the uphill position and the surface soil of the downhill position are overlapped to form a planting ridge.

The invention requires a slope surface less than 30 degrees. And (5) land preparation in dry seasons. The method of half digging and half filling is used along the contour line on the slope surface basically, the digging machine is used for covering and accumulating the soil at the upper slope position on the lower slope position, the soil at the lower slope position is not dug and is kept in the original state, and the soil at the upper surface and the soil at the lower surface are gathered together. The water collecting ditch is dug at the position of the upward slope, and the planting ridge is formed at the position of the downward slope. The whole terrain is changed into a plurality of horizontal steps which are connected up and down to form a step surface. Each terrace planting ridge is a tung tree planting belt. The distance between the terraces and the width of the terraces are different according to the gradient and the row spacing of the planted plants.

The mountain land grass planting irrigation pot is luxuriant, the roots of the weed irrigation pot are cut off through a land preparation technology, and the non-digging place (the downhill level surface) is covered by the soil on the uphill and can not grow, so that the growth of the grass irrigation pot is well controlled, and a better illumination and nutrition space is provided for seedlings.

The top soil is overlapped in the soil preparation process, so that the root system of the tung tree seedling can be quickly tied on the double-layer top soil with rich organic matter nutrition, and the growth of the seedling can be facilitated; the formed water collecting ditch has the function of water storage and collection, and water is supplemented to the nursery stock through water lateral seepage in the dry season.

The water collecting channel has another function on the planting of the tung tree, the tung nuts can directly fall off when the tung tree is mature, if the tung tree is on an original slope, the tung nuts can roll to a far downhill place and cannot be collected, and a great amount of loss of the harvesting benefit is caused.

The following comparative analysis was performed in conjunction with specific planting conditions:

in the 2 nd year (3 months at the bottom of seedling culture in the first year, 8 months at the bottom of mountain) from 4 middle ten days to 4 months at the bottom of the first year, the growth amount of the land diameter, the height of the tree in the current year, the number of leaves growing in the current year at the top, the number of lateral buds and lateral branches are measured, 3 different small vertical land environments are set for comparison, as seen from table 1, the effect difference between the direct planting of the whole land and the non-soil land is very obvious and simple and feasible according to the technology, and the technology promotes the efficient planting of the Chinese tung tree in the mountainous region to obtain higher economic benefit.

TABLE 1 soil preparation and soil preparation planting effect analysis

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications are all within the scope of the present invention.
