Detailed Description
The present invention will be described in further detail with reference to specific examples.
A production method of a green degradable mulching film containing microorganisms specifically comprises the following steps.
A. Collecting natural fallen leaves in autumn and winter, such as common leaves of Chinese parasol tree, Chinese white poplar, willow, ginkgo, etc.
B. Smashing fallen leaves into powder or paste by a pounding machine, mixing the smashed fallen leaves with water according to the proportion of 1:1, soaking, and boiling to thick leaf mud. Adding a sodium hydroxide solution with the concentration of 4% when the smashed fallen leaves are mixed and soaked with water, wherein the ratio of the sodium hydroxide solution to the water is 1: 20, removing lignin, carbohydrates, resins and the like in the raw materials, neutralizing organic acids and promoting the separation of cellulose.
C. Pulping the thick leaf mud, mashing, adding adhesive, stirring, filtering, and spreading on a bearing plate to make the leaf mud in thin layer. The leaf spreading slurry adopts the traditional paper making process, the obtained leaf slurry is fiber paper pulp, and other impurities can be removed by using a filter screen before spreading on the bearing plate.
The adhesive adopted in the step is brown sugar adhesive.
D. And (4) putting the bearing plate paved with the leaf slurry into a dryer for drying, and after naturally cooling, taking down the bearing plate to obtain the degradable mulching film.
