Problems solved by technology

[0004] In recent years, the state and local governments have invested a lot of manpower, material and financial resources in the restoration and management of the ecological environment, and have achieved certain results, but the survival rate of afforestation is not ideal
The main reasons are as follows: first, traditional methods are used for planting, and new materials and technologies are not paid enough attention to; second, although some new materials such as water-retaining agents are used, water-retaining agents are not resistant to salt and alkali, especially for plants containing calcium and magnesium. The hard water absorption effect of ions is poor, and the results of cotton fields and afforestation are also unsatisfactory; the third is that the vegetation is deserted, especially in recent years. Difficult to function

Abstract

The invention discloses an organic-inorganic multifunctional water-retaining agent for resisting saline and alkaline and a preparation method of the organic-inorganic multifunctional water-retaining agent. The organic-inorganic multifunctional water-retaining agent for resisting saline and alkaline is characterized in that the formula of the water-retaining agent includes humic acid, crylic acid, industrial starch, additives and attapulgite which are taken as raw materials, and a crosslinking polymerization process is adopted for preparing the organic-inorganic multifunctional water-retaining agent. According to the water-retaining agent, inorganic minerals, the attapulgite and organic minerals, namely humic acid are adopted to improve the saline-alkaline resistance, and simultaneously, trace elements such as nitrogen, phosphorus and potassium necessary for the growth of plants are provided, so that the double functions of water retaining and nutrient elements providing can be met by applying the water-retaining agent, further, the multiple functions are endowed to the water-retaining agent, and the requirements of forest planting in high saline-alkaline and barren soils in western area can be met.

Description

[0001] Technical Description [0002] The invention belongs to the technical field of water and soil conservation, and relates to a water-retaining agent and a preparation method thereof, in particular to an organic-inorganic type saline-alkali-resistant multifunctional water-retaining agent and a preparation method thereof, which is applicable to the field of agriculture and forestry, and can be used for drought resistance, seedling preservation, Increase production and income, improve soil, windbreak and sand fixation, water and soil conservation, etc. It is also suitable for afforestation in high salinity and barren soil.
