Abstract

The invention relates to the field of agricultural liquid mulching films, and discloses a liquid fertilizer mulching film with high water retention and a method for preparing the liquid fertilizer mulching film. The liquid fertilizer mulching film in a formula comprises acrylic acid, sodium hydroxide solution, potassium persulfate, aluminum chloride, N, N' methylene-bisacrylamide, sodium bicarbonate, seaweed concentrated liquid, polyvinyl alcohol, carboxymethyl celluloses, silk protein powder, oxygen producers and inorganic fertilizer particles. The method includes adding the acrylic acid, the potassium persulfate, the seaweed concentrated liquid, the polyvinyl alcohol, the carboxymethyl celluloses and the silk protein powder into the sodium hydroxide solution and carrying out stirring reaction; adding the aluminum chloride and the N, N' methylene-bisacrylamide into the sodium hydroxide solution and continuing to stir the sodium hydroxide solution; adding the oxygen producers, the inorganic fertilizer particles and the sodium bicarbonate into the sodium hydroxide solution, then carrying out stirring reaction to obtain a reaction product and cooling the reaction product to obtain a finished product. The liquid fertilizer mulching film and the method have the advantages that good film-forming effects can be realized by the degradable liquid fertilizer mulching film, soil structures can be improved, outstanding water retention and heat-insulation effects can be realized, and the liquid fertilizer mulching film is easy to degrade and has functions of increasing fertilizers and promoting growth of root systems of crops; the liquid fertilizer mulching film is good in soil binding property and difficult to wash out by rainwater.

Description

technical field [0001] The invention relates to the field of agricultural liquid mulch, in particular to a high water-retaining liquid fertilizer mulch and a preparation method thereof Background technique [0002] In the process of planting crops, plastic mulch is usually covered on the ground after the crops are planted to keep warm and keep moisture, so that the crops can emerge early, mature early and increase yield. The traditional plastic mulch is more troublesome in transportation, lamination and collection, which affects the efficiency. In addition, plastic mulch is easily blown away by the wind, affecting the growth of crops. Moreover, the plastic mulch is easily broken, and it is difficult to recycle the debris after remaining in the soil, and it is not easy to degrade, causing soil pollution, resulting in soil agglomeration and hardening, and a decline in fertility. [0003] The authorized announcement number is CN103613460B, and the Chinese invention patent wit...
