example 1

[0018] Example 1: Component A: 2.5g guar gum and 2.5g hydroxypropyl guar gum.

[0019] Component B: 3 g borax, 11 ml propylene glycol.

[0020] Pack components A and B separately.

[0021] Preparation method of solid water: Mix 200ml of water with component B, stir until borax is completely dissolved; then add component A into 860ml of water, stir continuously to make it fully swell, pour the solution of component B into component A In the medium, keep stirring to make it fully cross-linked and form solid water. The moisture release period of the solid water in the soil is about 33 days.

example 2

[0022] Example 2: Component A: 5.3 g guar gum.

[0023] Component B: 3 g borax, 11.5 ml propylene glycol.

[0024] Component C: 0.01 g of cellulase with an activity of 600 u / g.

[0025] Pack components A, B, and C into boxes separately.

[0026] Preparation method of solid water: Mix 200ml of water with component B, stir until borax is completely dissolved; then add component A into 730ml of water, stir continuously to make it fully swell, pour the solution of component B into component A , keep stirring to make it fully cross-linked, add component C and stir evenly to form solid water. The moisture release period of the solid water in the soil is about 18 days.

example 3

[0027] Example 3: Component A: 4.7 g Hydroxypropyl Guar.

[0028] Component B: 2.6g borax, 10.5ml propylene glycol.

[0029] Component C: 0.006 g of cellulase with an activity of 600 u / g.

[0030] Pack components A, B, and C into boxes separately.

[0031] Preparation method of solid water: Mix 200ml of water with component B, stir until borax is completely dissolved; then add component A into 770ml of water, stir continuously to make it fully swell, pour the solution of component B into component A , keep stirring to make it fully cross-linked, add component C and stir evenly to form solid water. The moisture release period of the solid water in the soil is about 23 days.

Abstract

The invention provides a water fixing agent comprising 22-30% of guar gum and / or hydroxypropyl guar gum, 12-18.5% of propylene glycol, and 50-500u / kg vitality unit of cellulase can be added. The agent can be used for preparing solid water through mixing with water, which can be applied to tree planting in dry land.

Description

technical field [0001] The invention belongs to the improvement of water-fixing agent formula and relates to the technical field of crop soil moisture improvement. Background technique [0002] In recent years, the desertification of soil has aroused the general concern of the whole society. my country has invested a lot of manpower and material resources to build ecological forests. Due to the lack of necessary means, drought has become a restrictive factor affecting the survival of afforestation. Solid water is a new technology product specially used for afforestation in arid environments. It provides technical support for afforestation in arid areas and solves the problem of water supply for afforestation in arid soils. It has broad application prospects and great social significance in the construction of my country's ecological environment. , Economic benefits. After retrieval, there are 4 related patents in this field: ①A kind of solid water (application number is CN 0...
