Abstract

The invention relates to the field of agricultural liquid mulching films, and discloses a black liquid fertilizer mulching film and a method for preparing the same.The black liquid fertilizer mulching film comprises asphalt, seaweed concentrated liquid, polyvinyl alcohol, carboxymethyl celluloses, silk protein powder, oxygen producers, inorganic fertilizer particles, alkyl diamine, tween and water.The method includes heating the asphalt until the temperature of the asphalt reaches 150-190 DEG C and stirring the asphalt; adding the seaweed concentrated liquid, the polyvinyl alcohol, the carboxymethyl celluloses, the silk protein powder, the oxygen producers, the inorganic fertilizer particles, the alkyl diamine and the tween into the water, uniformly stirring the seaweed concentrated liquid, the polyvinyl alcohol, the carboxymethyl celluloses, the silk protein powder, the oxygen producers, the inorganic fertilizer particles, the alkyl diamine and the tween and heating the seaweed concentrated liquid, the polyvinyl alcohol, the carboxymethyl celluloses, the silk protein powder, the oxygen producers, the inorganic fertilizer particles, the alkyl diamine and the tween until the temperatures of the seaweed concentrated liquid, the polyvinyl alcohol, the carboxymethyl celluloses, the silk protein powder, the oxygen producers, the inorganic fertilizer particles, the alkyl diamine and the tween reach 45-65 DEG C; uniformly mixing materials prepared at the steps 1) and 2) with one another and then grinding the materials to obtain the black liquid fertilizer mulching film.The black liquid fertilizer mulching film and the method have the advantages that excellent film-forming effects can be realized by the black liquid fertilizer mulching film on earth surfaces after the black liquid fertilizer mulching film is used, soil structures can be improved, outstanding water retention, heat preservation and soil moisture preservation effects can be realized, and the black liquid fertilizer mulching film is easy to degrade and has functions of increasing fertilizers and promoting growth of root systems of crops.

Description

technical field [0001] The invention relates to the field of agricultural liquid mulch, in particular to a black 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 with the applicat...
