Problems solved by technology

As we all know, most of the water-retaining agents are super absorbent resins, the cost is relatively high, and they cannot be accepted by most farmers, which has become an obstacle to the large-scale promotion and use of water-retaining agents.
Moreover, the function of the water-retaining agent in the prior art is mainly to retain water, and it does not have the effect of nutrition on the farmland, which is also one of its disadvantages.

Embodiment Construction

[0010] Below in conjunction with specific embodiment the present invention is described in further detail:

[0011] Multifunctional farmland water retaining agent, composed of the following raw materials by weight:

[0012]

[0013] The preparation method of the water-retaining agent: add all the reaction raw materials in proportion to the reaction kettle, heat to 50-60 degrees, keep it warm for 1-2 hours under stirring conditions, send the product into a dryer and dry it at 100-120 degrees Dry, the product is obtained after granulation.

[0014] The inorganic mineral is one or a combination of fly ash, kaolin or weathered coal.

[0015] The fertilizer is nitrogen, phosphorus and potassium fertilizer.

[0016] When in use, mix the above-mentioned composite farmland water-retaining agent with the soil in the farmland, apply it evenly in the furrows, and then water it.

Abstract

The invention discloses a multifunctional farmland water holding agent, which consists of the following raw materials in part by weight: 30 to 40 parts of acrylic acid, 30 to 40 parts of inorganic mineral, 40 to 50 parts of water, 5 to 8 parts of alkali, 0.5 to 1 part of cross linker, 0.2 to 0.5 part of surfactant, and 30 to 40 parts of fertilizer. A preparation method of the water holding agent comprises the following steps of: adding all the reaction raw materials in a ratio into a reaction kettle, heating the raw materials to the temperature of between 50 and 60 DEG C, performing heat preservation for 1 to 2 hours with stirring, delivering the product to a dryer, drying the product at the temperature of between 100 and 120 DEG C, granulating, and thus obtaining the water holding agent. The water holding agent is a solid water holding agent; meanwhile, inorganic effective ingredients and chemical fertilizers are added in the water holding agent so as to increase the nutrition and apply fertilizers to a farmland; and the water holding agent has low cost, synergistic and slow-release effects and good water holding effect.

Description

technical field [0001] The invention relates to a water-retaining agent, in particular to a multifunctional farmland water-retaining agent. Background technique [0002] With the development of science and technology, more and more water retaining agents are used in farmland. As we all know, most water-retaining agents are superabsorbent resins, which are relatively expensive and cannot be accepted by most farmers, which has become an obstacle to the large-scale promotion and use of water-retaining agents. Moreover, the function of the water-retaining agent in the prior art is mainly to retain water, and it does not provide nutrition to the farmland, which is also one of its disadvantages. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multifunctional farmland water-retaining agent which is cheap and has nutritional and fertilizer-retaining effects on farmland. [0004] In order to solve the above-mentioned ...
