Problems solved by technology

The first disadvantage is that the funnel is completely buried in the tree planting pit, the area of ​​the funnel mouth is small, and the amount of water collected is small, which cannot solve the problem in severe drought areas; the second is that the funnel is deeply buried in the soil, and the soil in the funnel must first absorb enough water. Excess water can flow into the roots along the funnel, and the water collection efficiency is low
The invention patent with the application number of 200420051553.1 "Planting trees with long-lasting film in arid areas" discloses a method of collecting and retaining water by wrapping tree roots in the shape of apples with plastic film in tree planting pits. There are shortcomings of small water collection surface and low water collection efficiency. At the same time, it does not take into account the fact that trees also consume a lot of water during the growth process. It is believed that the wrapped water will evaporate, condense, re-evaporate, and re-condense forever in the film. no loss it's wrong

Embodiment approach 1

[0070] Embodiment 1. The structure description of a surface type drought-resistant black film funnel for tree planting:

[0071] In the picture, the black film funnel is placed on the surface above the tree planting pit. The black film funnel is divided into an upper mouth, a lower mouth and a side; the upper mouth has a diameter of 0.6m, and the lower mouth has a diameter of 0.15m; the upper mouth is surrounded by a barrier Earth wall, the height of the retaining wall is 8cm, which is used to prevent the external soil from falling into the funnel; the retaining wall is wrapped with a film extending from the side of the funnel and buried on the outside of the retaining wall; The ground 7 is arranged into a funnel-shaped slope with low middle and high surroundings, so that the rain in the funnel can concentrically converge to the bottom of the funnel; the membrane of the bottom of the funnel is buried in the upper part of the tree planting pit with water retaining sand, and ordinar...

Embodiment approach 2

[0072] Implementation mode 2. Description of the use method of a surface type drought-resistant black film funnel for tree planting:

[0073] 1. Dig a hole in advance

[0074] The tree planting pit must be dug in advance before planting the tree. The planting pit should be dug one month before planting the tree. If the tree is planted in spring, the tree planting pit should be dug before winter so that the dug soil can be fully weathered and loosened through the alternation of freezing and thawing.

[0075] 2. Planting trees and building slopes:

[0076] First erect the saplings in the middle of the tree planting pit, and then fill the pit to 10cm away from the pit. With the sapling as the center, the ground surface within a radius of 70cm is arranged into an inwardly inclined funnel-shaped slope.

[0077] 3. Build earth ridge:

[0078] With the sapling as the center, a circular soil ridge with a diameter of 70cm and a height of 12cm is built with soil outside the tree pit.

[0079] 4. C...

Embodiment approach 3

[0083] Implementation mode 3. Use surface type drought-resistant tree planting black film funnel to water and protect trees

[0084] The watering and water conservation method of the surface type drought-resistant tree planting black film funnel is a method of using the surface type drought-resistant tree planting black film funnel to irrigate the trees that have been planted with concentrated rainwater. It includes three steps of land preparation, film mulching and sand filling:

[0085] 1. Site preparation:

[0086] ① Take the already planted tree 6 as the center, repair the ground surface within a radius of 80cm to an inwardly inclined funnel-shaped shallow pit;

[0087] ② Build a 6cm-high annular soil ridge outside the funnel pit.

[0088] 2. Laminating:

[0089] ① Take 1 piece of black opaque high-strength anti-aging plastic film;

[0090] ②Cut a hole with a diameter of 25cm in the middle of the film;

[0091] ⑦ Cut a cut from the edge of the film to the inner hole;

[0092] ⑧ Put the ...

Abstract

Around a survived tree root, a funnel-shaped slope taking the tree as a center of a circle is formed on the ground, a ring of ridge is built along the outer edge of the slope, the center of a black opaque high-strength ageing-resistant plastic film, which is the same as the slope in area, is cut with a hole, an opened gap is cut from the edge of the film to the center of the film, and the film is sleeved on the seedling, spread on the slope to cover the whole ridge and tightly buried and compacted; a lower opening is buried by sand; and a black film funnel taking the seedling as the center is formed. In rainy days, the film funnel can effectively collect rainwater; and in sunny days, the film funnel can effectively keep water in soil and improve the drought-resisting ability of soil. Furthermore, the black film funnel can prevent the harm of weed. The method is low in cost and high in effect.

Description

Technical field [0001] A surface type drought-resistant tree planting black film funnel relates to the technical field of forest tree cultivation, and specifically relates to a tree planting technology in which a tree planting ground is made into a funnel shape and covered with a black film. Background technique [0002] my country has a vast land area that belongs to the inland arid area, which is characterized by low rainfall and large evaporation, which makes plant growth very difficult. For example, the annual rainfall in Ningxia is 150-400mm, in Gansu it is 42-760mm, and in Xinjiang it is only 150mm. , And the annual rainfall in Inner Mongolia is only 50-450mm, and the annual evaporation in these areas is above 1000mm. Due to lack of water, artificial afforestation is very difficult and the survival rate is low. The invention and creation of a method that is simple and easy to implement, can fully accumulate and utilize natural rainfall, is very necessary for afforestation, ...
