Abstract

A pouch type planting method on sloping field comprises scraping the pool bottom for planting into an adverse slope form opposite to the slope direction, wherein the planeform of the pool is pouch type, planting the seedling in the pool against to the above sidewalls, digging a pyramidal pool with the butt end as the center, and covering with film and clay. The invention can make full use of rainwater flowing along the slope, avoid the pool down edge from falling down, and effectively protect the seedling from wind.

Description

Eye-bag type sloping field tree-planting method

One, technical field:

The present invention relates to hillside fields tree planting technology, particularly a kind of eye-bag type hole tree-planting method.

Two, background technology:

The hillside fields plants trees and not only waters difficulty, simultaneously because special geographical environment during heavy rains, also is easy to cause water and soil loss, so that cause tree root exposed outside, also can cause the lodging of planting trees in the time of seriously.For addressing the above problem, known method is to assemble arc stalk with stone or earth below the tree base, and this measure is for light rain or moderate rain situation, can play certain water and soil conservation effect, but one meets heavy rain or heavy rain, and rainwater can wash away the ridge easily, and the planting trees also will lodge thereupon.

Three, summary of the invention:

The purpose of this invention is to provide a kind of eye-bag type sloping field tree-planting method, to solve the water and soil conservation difficult problem that the hillside fields plants trees.

The object of the present invention is achieved like this: the flat shape of the hole of will waiting to plant trees scrapes out similar people's pouch shape, join by two relative camber lines and to form with same curvature radius, the radius of curvature of this camber line is 3～4m, hole is 1.3～1.5m along the lateral dimension of sloping direction, longitudinal size is 1.8～2m, it is 45～60 degree with horizontal plane angle that the end, hole scrapes out one, and the adverse slope shape opposite with the ground line gradient direction, to cheat after the bottom surface digs pine, again with wall 40～50cm place above also distance is cheated on the cross central line of sapling field planting in the hole, cover earth, make the horizontal and following square opening that is lower than the hole of earth in the hole along 10～20cm, base portion with tree is that the conical surface is dug into earth in the center again, the lateral dimension of the conical surface is consistent with the pitted surface lateral dimension, its central depths is 20～25cm, after watering, get a plastic film consistent again with conical surface lateral dimension, cut a road junction from film edge to its center, and to cut a diameter in the center be to wait to plant trees behind the hole of 2 times of basic diameters of tree, film is covered on the conical surface, dazzling on film, and to make the aperture of eyelet be 3～5mm, pitch-row is 5～7cm, covers the thick earth of 3cm at film surface at last.

Adopt such scheme can receive following remarkable result:

1, hole is scraped out adverse slope shape, can reduce volume of earthwork greatly, make end opening one side in hole become the real soil layer of Ju shape fastening type again, it can not collapsed under the situation of heavy rain or heavy rain.

2, the flat shape with the hole scrapes out pouch shape, can further reduce the shoveling amount and can increase the amount of rainfall that the upper edge, hole admits suitable slope to flow down again.

3, because the adverse slope shape of hole and the acting in conjunction of plane pouch shape make near coal-mine upper edge both and between the tree base plane bigger difference in height be arranged, make the wall of upper edge, hole form cambered surface again, this will make sapling obtain effective wind resistance protection.

4, keep in the hole effect that certain height difference between native face and near coal-mine lower edge can play collected rainwater during earthing, make more rainwater can cheat the end certainly and ooze down, thereby soil is moistening in keeping cheating.

5, be that a conical pit and cover film and earth are dug in the center with the butt, both helped preventing to set basic water evaporates, reduce the number of times that waters, the water that helps again being watered can concentrate on root, can also collect rainwater effectively and concentrate the supply root, can prevent that strong wind from having swept film and avoid the aging of film simultaneously.

6, dazzling on film, it is ventilative both to have helped root system, can make the distribution of the water that enters rainwater that the tree primitive period encloses and pouring more become reasonable again.

Claims

1, a kind of eye-bag type sloping field tree-planting method, it is characterized in that: the flat shape of the hole of will waiting to plant trees scrapes out similar people's pouch shape, join by two relative camber lines and to form with same curvature radius, the radius of curvature of this camber line is 3～4m, hole is 1.3～1.5m along the lateral dimension of sloping direction, longitudinal size is 1.8～2m, it is 45～60 degree with horizontal plane angle that the end, hole scrapes out one, and the adverse slope shape opposite with the ground line gradient direction, to cheat after the bottom surface digs pine, again with wall 40～50cm place above also distance is cheated on the cross central line of sapling field planting in the hole, cover earth, make the horizontal and following square opening that is lower than the hole of earth in the hole along 10～20cm, base portion with tree is that the conical surface is dug into earth in the center again, the lateral dimension of the conical surface is consistent with the pitted surface lateral dimension, its central depths is 20～25cm, after watering, get a plastic film consistent again with conical surface lateral dimension, cut a road junction from film edge to its center, and to cut a diameter in the center be to wait to plant trees behind the hole of 2 times of basic diameters of tree, film is covered on the conical surface, dazzling on film, and the aperture that makes eyelet is 3～5mm, and pitch-row is 5～7cm, covers the thick earth of 3cm at film surface at last.
