Water retaining agent is a kind of high molecular polymer, which has the functions of drought resistance, water saving and water retention, and can greatly improve the quality of afforestation in arid areas. In my country, the promotion and application of water-retaining agents in Chinese pine, oriental arborvitae and other tree species are obvious. Because of its good water-retaining effect and low cost, it is more and more widely used in my country.

In view of the current technical requirements arising from the construction of the ecological environment and the development of water-saving agriculture, the nature and types of water-retaining agents, water absorption mechanism, and application effects are briefly described, and the problems existing in the agricultural use of water-retaining agents are discussed.

With the rapid economic development, agricultural production has put forward higher requirements for water-saving irrigation. Only by saving water can agricultural production not reduce production due to water shortage. Therefore, the rational application of water-retaining agents in water-saving irrigation is of great significance for improving the level of agricultural production.

The water retaining agent is a super absorbent resin (SAP). From the raw materials, it can be divided into starch, cellulose, and polymer.

The application of water-retaining agent in the nursery, planting, and management of garden plants, and analyze the precautions in the application to improve the quality of garden engineering and reduce the cost of garden engineering and management.

The following factors should be considered in the amount of drought-resistant and water-retaining agent:

Compared with the water-retaining agent, the SOD, CAT, POD activity, Pro content and root vigor were significantly increased after the water-retaining agent was added, and the MDA content and the relative conductivity of the leaf were significantly reduced.

Water-retaining agents are divided into starch, cellulose, and synthetic polymer based on the source of raw materials. They all have the characteristics of being insoluble in water, insoluble in organic solvents, and capable of absorbing water from hundreds to thousands of times their own weight, but starch and cellulose The product is easily corrupted and invalid.

With the rapid development of modern industry, rapid population expansion, and deterioration of water resources, the problems of drought and desertification have become increasingly prominent. The development of water-retaining agents is an effective way for scientists from various countries to solve these problems.

Early drought is a limiting factor in agricultural production in arid areas. In agricultural production, excessive exploitation of groundwater has led to a continuous decline in groundwater levels, and the shortage of water resources is not optimistic.

One of the technical problems in the preservation of fruits and vegetables is the production of dew in the packaging. The dew is a culture medium that causes microorganisms to multiply and accelerates the decay of fruits and vegetables.

Water retaining agent is a kind of polymer polymer, which has the functions of drought resistance, water saving and water retention, and can greatly improve the quality of afforestation in arid areas. The effect of the promotion and application of water-retaining agents in many tree species such as Chinese pine and Platycladus orientalis is obvious. Because of its good water-retaining effect and low cost, it is more and more widely used.

After applying soil water retaining agent, the soil water retaining agent absorbs water, there is very little physical (leakage, evaporation) water loss, and can repeatedly absorb and supply water for a long time; the soil layer where the seed or cutting root is located is more water and heat It is stable, is conducive to seed germination, rooting and growth of cuttings, and also reduces labor costs.

The research shows that the pre-absorbed superabsorbent resin can improve the working performance of freshly mixed concrete, while the dry mixing of superabsorbent resin will reduce the workability of the freshly mixed slurry because the superabsorbent resin will absorb some of the free water in the concrete.
