Method for planting trees by root irrigation

Abstract

The invention relates to a method for planting trees by root irrigation. The method comprises the following steps: preparing trees that need to be planted, peeling off soil from a main root and / or outer ends of more than one lateral roots of the tree, wrapping the exposed main root and / or the outer ends of more than one lateral roots of the tree respectively with a waterproof film, respectively inserting a liquid transport tube into each waterproof film, and connecting a liquid inlet of each liquid transport tube with a container filled water or nutrient solution for trees; digging tree wellsfor planting trees and burying the roots of the tree together with the waterproof film and the liquid transport tube in the tree well with soil; enabling water filled in the container for transportingliquid to flow towards the main root and / or the lateral roots wrapped with the waterproof film of the tree so as to directly deliver water to the main root and / or the lateral roots wrapped with the waterproof film of the tree. The purpose is to provide a method for planting trees by root irrigation, which is better than a drop irrigation technique in saving water, capable of satisfying growth andliving needs of the tree with a very small quantity of water, and capable of effectively improving the survival rate of transplanting the taller trees or the trees with well-developed root systems.

Description

technical field [0001] The invention relates to forestry, in particular to a root irrigation tree planting method. Background technique [0002] Drip irrigation technology is to slowly drip water to the soil under low pressure through the drippers on the main pipe, branch pipe and capillary pipe; it is an irrigation system that directly supplies filtered water, fertilizers or other chemicals to the soil. Drip irrigation has no spray or ditch water, only water trickles out slowly and enters the soil under the action of gravity and capillary tubes. Drops of water near the roots of the crops keep the soil in the main root zone of the crops always at optimum water content. Compared with surface irrigation and sprinkler irrigation, drip irrigation saves water and labor, and increases production and income. Because water does not move in the air during irrigation, does not wet the leaves, and does not effectively moisten the soil outside the drip irrigation area, so the amount of...

Problems solved by technology

Compared with surface irrigation and sprinkler irrigation, drip irrigation saves water and labor, and increases production and income. Because water does not move in the air during irrigation, does not wet the leaves, and does not effectively moisten the soil outside the drip irrigation area, so the amount of water directly lost to evaporation is less than Ground irrigation and sprinkler irrigation; drip irrigation is also easy to control the amount of water, without causing surface runoff and deep soil leakage, so it can save 35-75% of water than sprinkler irrigation. The root system transports water to the inside of the plant. However, most of the water transported to the soil near the plant root by drip irrigation technology is not absorbed by the plant, but is lost through evaporation and seepage. This water loss is especially severe in soils that are dry and water-deficient

Tree planting is usually carried out in spring every year. In this season, there is less precipitation in the northern part of our country. Those lands on hillsides and Gobi deserts that need to be planted and greened are often in an extremely dry state, and there are usually no nearby hillsides that can be irrigated on a large scale. The water source of the land in the Gobi Desert is extremely short of water on the surface. Even if the drip irrigation technology is used, it cannot meet the water demand for planting trees in these areas. During this period, sufficient water must be supplied to allow it to complete the rooting and growth process required for survival. As a result, the survival rate of trees planted in these areas is very low, far below the national standard, so that some experts concluded that large-scale tree planting in these areas, such as the Loess Plateau, is simply not possible, despite the fact that these areas were historically covered with dense forests

In addition, when transplanting some taller trees or trees with more developed root systems, most of the original roots of the trees will be cut off, causing serious damage to the roots, which will also cause the planted trees to die due to severe water shortage. die
