Embodiment Construction

[0023] A method of degradable bioactive mulch prepared by using olive processing waste liquid, comprising the following steps:

[0024] (1) Take the olive processing waste liquid and filter it to remove the slag, then circulate it through the filter tank equipped with porous polyamide resin microspheres at a speed of 0.1m / s, and collect the filtrate after circulating for 10 hours;

[0025] (2) Mix the weathered coal and montmorillonite evenly, then crush them through a 100-mesh sieve, and use the obtained materials for later use;

[0026] (3) Put the material obtained in step (2), polyvinyl alcohol, sodium dodecylbenzenesulfonate, and water into the reaction kettle in sequence, turn on the stirring device, raise the temperature of the system to 80°C, and react and mix at a speed of 100 rpm 30min, then add silane coupling agent kh550, continue stirring and mixing for 50min, then discharge, dry and set aside;

[0027] (4) Put the filtrate obtained in step (1) together with the ...

Abstract

The invention discloses a method for preparing a degradable bioactive mulching film by using waste liquid produced by olea europaea processing; the method realizes the effective conversion and utilization of the waste liquid produced by olea europaea processing. According to the method, materials such as humic acids and montmorillonite are added based on the traditional film-forming materials such as polyvinyl alcohol, polyacrylamide and starch, and a composite film-forming material with moderate degradation cycle and good film strength is generated under the cross-linking action of a silane coupling agent, so that the defects that the traditional biomass degradable mulching film material is rapid in degradation velocity and poor in mechanical properties of a film layer are overcome. The method maintains the bioactive components in the waste liquid to the utmost extent by using mild preparation conditions, can obviously improve the growth conditions of crops, and improves the soil environment; the prepared product is powder, thus being convenient to transport and store.

Description

technical field [0001] The invention relates to the technical field of degradable agricultural mulching films, in particular to a method for degradable bioactive mulching films prepared from olive processing waste liquid. Background technique [0002] Olive oil is a world-renowned woody oil tree species. Olive oil can be produced from its ripe fruit after physical pressing and separation. Olive oil is rich in unsaturated fatty acids, phenolic substances and fat-soluble vitamins and other active ingredients, and is widely favored by people all over the world. The favored high-grade edible vegetable oil. As the edible efficacy of olive oil is gradually known to consumers, the market sales are gradually increasing, and the output is also increasing year by year, and the amount of olives introduced from all over the world is also increasing. In the process of olive oil processing, a large amount of olive processing waste liquid will inevitably be produced after the production o...
