Abstract

The invention relates to the field of agricultural liquid mulching films and discloses a black liquid mulching film and a preparation method thereof. The liquid mulching film is prepared from the following substances: asphalt, seaweed concentrate, polyvinyl alcohol, carboxymethylcellulose, fibroin powder, oxygenate, weeding particles, alkyl diamine, Tween and water. The preparation method comprises the following steps: heating the asphalt to 150 to 190 DEG C and stirring; adding the seaweed concentrate, the polyvinyl alcohol, the carboxymethylcellulose, the fibroin powder, the oxygenate, the weeding particles, the alkyl diamine and Tween to water and uniformly stirring and heating to 45 to 65 DEG C; uniformly mixing the materials prepared in the step 1) and the step 2), and then grinding to prepare the black liquid mulching film. After the liquid mulching film is used, a film forming effect on the ground surface is good, the soil structure can be improved, water retention, temperature preservation and soil moisture preservation effects are good, and the mulching film is easy to degrade and has the effects of weeding 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 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 application date of...
