Abstract

A kind of modifying agent for desert planting, which is characterized in that mixed by the component of following mass percent:70~80%, 200~600 mesh of seaweed with colloid;10~15%, 100~600 mesh of clay;10~15%, 200~400 mesh of super absorbent resin.The present invention also provides a kind of modification methods for desert planting.The present invention can be very good filling sand gap using the tiny seaweed of particle, clay, clay has impermeability, and seaweed has good caking property, clay, super absorbent resin and the grains of sand can be sticked together, it improves the water-retaining property of surface layer sand ground and reduces leakage, while also functioning to sand fixation;The change of volume is so that the sand ground after improvement will not still have good gas permeability because of cohesive and hardened when super absorbent resin stores up/release water.

Description

Modifying agent and modification method for desert planting

Technical field:

The present invention relates to desert planting technical field, more particularly to a kind of modifying agents and improvement side for desert planting Method.

Background technology:

China's desert area is big, and area is also constantly expanding, semidesert area and with desert adjacent zone how Husky returning to the field is effectively moved back, is had great significance with protecting/bringing more land under cultivation.

Vegetation needs water, and since desert has high evaporation capacity, high seepage rate, the center that traditional sand control surrounds is how to protect Water.Desert water conservation has been pushed ahead major step by the development of recent decades water-keeping material, image height water-absorbing resins.

But since the gap between the grains of sand is excessive, super absorbent resin class material is used merely, although solving water conservation Problem, but still there is a large amount of irrigation waters leakage to fall, when practical cultivation, fertilizer applying under because leaching leaks waste very seriously. In addition, sand fixation can not be played using super absorbent resin class material merely, the surface layer grains of sand and water-keeping material are possible to report and scrape It walks, does not both have water retention, can not also fix plant.

Invention content:

In consideration of it, it is necessary to design a kind of modifying agent for desert planting, and provide a kind of for desert planting Modification method.

A kind of modifying agent for desert planting is mixed by the component of following mass percent:

70~80%, 200~600 mesh of seaweed with colloid;

10~15%, 100~600 mesh of clay;

10~15%, 200~400 mesh of super absorbent resin.

Preferably, seaweed is red algae or kelp.

A kind of modification method for desert planting includes the following steps:

(1), by with colloid seaweed impurity elimination, clean, dry, be crushed to 200~600 mesh;Clay is crushed to 100~ 600 mesh;

(2), by step (1) treated seaweed 70~80%, the high water absorption of clay 10~15% and 200~400 mesh Property resin 10~15% stirring, be mixed and made into modifying agent, the percentage is mass percent;

(3), the modifying agent of step (2) is mixed with the surface layer grains of sand of sand ground, wherein the mass ratio of modifying agent be 0.3~ 0.6%, the thickness of the surface layer grains of sand is 10~25cm;

(4), it waters on step (3) mixed sand ground, so that the super absorbent resin in the grains of sand of surface layer is absorbed water, and make sea Algae, clay and the grains of sand cohere.

The present invention can be very good filling sand gap using the tiny seaweed of particle, clay, and clay has impermeability, And seaweed has good caking property, and clay, super absorbent resin and the grains of sand can stick together, and improves the guarantor of surface layer sand ground It is aqueous and reduce leakage, while also functioning to sand fixation;The change of volume is so that after improvement when super absorbent resin stores up/release water Sand ground will not still have good gas permeability because of cohesive and hardened.

Specific implementation mode:

A kind of modifying agent for desert planting is mixed by the component of following mass percent:

70~80%, 200~600 mesh of seaweed with colloid;

10~15%, 100~600 mesh of clay;

10~15%, 200~400 mesh of super absorbent resin.

In the present embodiment, seaweed is red algae or kelp.

A kind of modification method for desert planting includes the following steps:

(1), by with colloid seaweed impurity elimination, clean, dry, be crushed to 200~600 mesh;Clay is crushed to 100~ 600 mesh;

(2), by step (1) treated seaweed 70~80%, the high water absorption of clay 10~15% and 200~400 mesh Property resin 10~15% stirring, be mixed and made into modifying agent, the percentage is mass percent;

(3), the modifying agent of step (2) is mixed with the surface layer grains of sand of sand ground, wherein the mass ratio of modifying agent be 0.3~ 0.6%, the thickness of the surface layer grains of sand is 10~25cm;

(4), it waters on step (3) mixed sand ground, so that the super absorbent resin in the grains of sand of surface layer is absorbed water, and make sea Algae, clay and the grains of sand cohere.
