    Drought is one of the most frequent meteorological disasters in China, and it is an urgent problem to be solved in the cultivation of flowers and plants in arid areas, and the use of water-retaining agent plays an important role.

    Water retaining agent, also known as soil water retaining agent, high water absorbent agent, humectant, high water absorbent resin, polymer water absorbent agent, is a high water absorbent polymer made of strong water absorbent resin. It can quickly absorb deionized water hundreds of times or even thousands of times heavier than itself, tens of times to hundreds of times salty water, and has the function of repeated water absorption, expansion into hydrogel after water absorption, can slowly release water for flowers and plants to absorb and utilize, thereby enhancing soil water retention, improving soil structure, reducing deep water leakage and soil nutrient loss, improve water utilization. It is an effective means to regulate soil water, heat and gas conditions, improve soil structure and increase soil fertility. Due to the cross-linking of the molecular structure, the water absorbed by the molecular network can not be squeezed out by simple physical methods, so it has a strong water retention. It is like a micro reservoir for seeds and plant roots slow absorption, itself can repeatedly release and absorb water, water retention agents and pesticides, root powder and fertilizer, etc., can also make them slow release, improve utilization, non-toxic and corrosive, degradation of plants and soil beneficial and harmless

    The functions of Water retaining agent

    One is insulation. The absorbed water can be used to maintain part of the heat generated by the daytime light to adjust the night temperature and reduce the temperature difference between day and night of the soil. If there is 0.1%-0.2% water retaining agent mixed in the sandy loam 10cm soil layer, the temperature difference between day and night is only 11-13℃. The soil without water retaining agent is between 11 and 19.5 ° C.

    The second is to keep fertilizer. The water-retaining agent can fix the nutrients needed for plant growth such as fertilizers and pesticides dissolved in water, which can reduce the leaching loss of soluble nutrients to a certain extent and improve the utilization rate of water and fertilizer.

    The third is to improve the soil structure. When the water-retaining agent is applied into the soil, with the regular change of water absorption expansion and water loss shrinkage, the surrounding soil can be changed from compact to loose, and the porosity increases, thus improving the permeability of the soil to a certain extent.

    Fourth, promote plant growth and development. Herb flower seeds treated with water-retaining agent have the effect of promoting growth and development. The number of roots, tillers, stem diameter and plant height of grass flower treated with water retaining agent were increased compared with those of untreated grass flower.
