Film bilateral catchment and preventing evaporation plant planting and maintenance method

Abstract

The present invention discloses a film bilateral catchment anti-evaporability woody plants (including tree and shrub flower) planting and maintaining method. The said planting method comprises: down excavation planting hole for planting plants, putting seedling into the said planting hole, then burying soil; covering the catchment film with edge-incision and round hole on the said seedling root base, making the round hole surround seedling root base, sealing catchment film edge-incision, and then fixing the circumference of the catchment film at the edge of planting hole to form a low in the middle and high on the periphery pan shape, so as to form catchment space between catchment film and burying soil. The present invention has water-storage, water-preserving or anti-evaporability technical effect, suitable for afforestation and tending in arid area, and for planting and maintaining seedlings in city garden afforestation engineering, therefore improving the survival rate of afforestation and the preservation rate of seedlings.

Description

Technical field [0001] The invention relates to a method for planting and maintaining plants, in particular to a method for planting and maintaining plants with water collection on both sides of a membrane to resist evaporation. Background technique [0002] Water is an important part of the ecosystem and the basis and characteristic of the existence of life phenomena; where there is water, there is life, and without water, there is no life. This has become a universal truth that goes without saying. According to reports: The arid and semi-arid regions of the world involve more than 60 countries and regions, accounting for about one-third of the global land area; my country's arid and semi-arid regions account for more than half of the land area. Such a large-scale arid environment has seriously affected the survival and activities of mankind, and is a permanent subject for mankind to overcome and transform nature for a long time. [0003] In order to improve the environment or d...

Problems solved by technology

[0003] In order to improve the environment or delay the deterioration of the environment, large-scale afforestation and greening of mountains, rivers and rivers have been carried out in an all-round way in my country's "Three North" regions; The low rate is still a problem: it is greatly affected by the weather, few seedlings survive, or the trees that have been planted and survived die after a period of time, the root cause is still lack of water

[0007] For forest trees, CN 1568660A discloses the method of flat film covering to prevent water evaporation and improve the survival rate of Pinus sylvestris sylvestris. However, it does not involve the use of film covering to collect atmospheric precipitation; There are holes and gaps on the plate, which can collect rainwater, block sunlight, and reduce root evaporation. However, the cost of this special plate will not be very low, and water will still be lost around the plate; CN 1820578A discloses water collection, storage Afforestation methods for water and water retention, but the water storage adopts engineering facilities, the cost is high, and water lifting facilities and processes are added, and the water collection and water retention measures with membranes lack outstanding features

[0008] For crops, CN 1063309C discloses a sowing method for self-rupturing of the film covering of the crops, using a relatively thin film, and pressing the soil right above the sowing rows or holes, which is beneficial to water retention, so that the seedlings burst out of the film, and natural precipitation cannot be utilized; CN 1411694A discloses a film-covered planting method with a drip irrigation system, which still cannot be applied to dry land without irrigation conditions
