Problems solved by technology

[0003] The desert (land) control method is to plant crops, ecological forests or vegetation to fix sand, but the water retention of desert (land) is very poor, so one of the technical keys for planting crops, ecological forests or vegetation is to obtain the function of water retention and anti-seepage , and can retain the good air permeability of the sand
The beach saline-alkali land contains a lot of salt water, which is not suitable for the survival and growth of crops or ecological forests. Even if the planting soil is laid on the saline-alkali land, the salt in the saline-alkali land at the bottom will still rise with the water and cause the salinization of the upper planting soil. Therefore, planting in saline-alkali land One of the technical keys for crops, ecological forests or vegetation is to obtain the function of anti-seepage while retaining good air permeability
[0004] For desert, sandy land and saline-alkali land crops, ecological forest or vegetation planting, there is still no planting structure, technology and method with good planting effect. Economical and effective planting structure, technology and method are still the current desert, sandy and Difficulties to be solved in saline-alkali land management

Embodiment 1

[0039] Excavate the surface desert sand in plot A1 to form a square flat bottom, surrounded by 25° slopes, and a large pit with a depth of 70 cm, and then spread the commercially available hydrophobic nano-calcium carbonate with a particle size of 80nm on the flat bottom of the inner pit And on the surface of the surrounding slopes, a hydrophobic nano-calcium carbonate layer with a thickness of 12 cm is formed. After compaction, desert sand is spread to form a planting soil layer, and then the sand tent seeds are sown, and they grow naturally until they are harvested.

Embodiment 2

[0049] Dig out the 15 cm thick surface desert sand in the A2 plot, and then dig out circular arc-shaped pits with a depth of 30 cm one by one, and spread the commercially available hydrophobic nano-calcium carbonate with a particle size of 30nm on the pits. On the inner surface of the pit and on the edge of the pit, a layer of hydrophobic nano-calcium carbonate layer with a thickness of 10 cm is formed on the inner surface of the pit and on the edge of the pit, and then desert sand is filled in the pit to form a planting soil layer, and a sand tree is planted in each pit. Jujube seedlings, and finally, spread 15 cm thick desert sand on the surface. Subsequently, the seedlings of Eleuthero jujuba grow and develop naturally.

Embodiment 3

[0059] Excavate the desert sand on the surface of the A3 plot to form a square flat bottom, surrounded by 25° slopes, and a large pit with a depth of 65 cm, and then spread a layer of 200g / m 2 The breathable and water-permeable polypropylene geotextile, and then spread a layer of hydrophobic nano-calcium carbonate layer with a particle size of 15 cm and a particle size of 70 nm on the polypropylene geotextile, and then spread a layer of hydrophobic nano-calcium carbonate layer with a specification of 300g / m 2 The breathable and water-permeable polypropylene geotextile is used, and then a layer of 20 cm clay-sand soil layer is laid on the polypropylene geotextile. After filling with water, a paddy field with a surface water depth of 10 cm is formed, and then rice is planted. The rice output reaches 473 kg / mu.

Abstract

The invention discloses a planting structure and method in desert, sandy land and saline-alkali land. The planting structure for the desert, the sandy land and the saline-alkali land is that a hydrophobic nano calcium carbonate layer is spread between a substrate soil layer and a planting soil layer, a water permeable and air permeable cloth layer is arranged between the substrate soil layer and the hydrophobic nano calcium carbonate layer and / or between the planting soil layer and the hydrophobic nano calcium carbonate layer, the shape of the hydrophobic nano calcium carbonate layer is preferably concave downwards, or the hydrophobic nano calcium carbonate layer is surrounded by water-impermeable surrounding edges with hydrophobic inner surfaces, and the hydrophobic nano calcium carbonatelayer is closely adhered to the surrounding edges. According to the technology disclosed by the invention, crops, ecological forests or vegetation planted in the desert, the sandy land and the saline-alkali land by using the technology have a high survival rate and rapid growth.

Description

1. Technical field [0001] The invention relates to a planting structure and a planting method, in particular to a planting structure and a planting method in deserts, sandy lands and saline-alkali lands. 2. Background technology [0002] Desertification causes the disappearance of a large number of planting and livestock lands every year, and desert wind and sand are now becoming more and more serious environmental hazards. Desert control is still a serious issue facing our country and the world. In addition, the use of tidal flat sandy land, especially beach saline-alkali land, through planting crops, ecological forests or vegetation management is an important way to expand the land for crops. [0003] The desert (land) control method is to plant crops, ecological forests or vegetation to fix sand, but the water retention of desert (land) is very poor, so one of the technical keys for planting crops, ecological forests or vegetation is to obtain the function of water reten...
