Introduction to composite environmental friendly degradable liquid film

composite environmental friendly degradable liquid film was successfully developed in Jinan University. The research group, jointly composed of the school of chemistry and chemical engineering of Jinan University and Jinan China Resources handing Technology Co., Ltd., and led by Dr. Sun Guoxin, Deputy Dean and professor of the school of chemistry and chemical engineering of Jinan University, spent half a year studying various technical schemes in detail and finally worked out the best technical scheme, A compound environmental friendly degradable liquid film was developed

I: introduction to compound environmental friendly degradable liquid film

innovative points of the product: (1) compound environmental friendly degradable liquid film can eradicate the problem of "white pollution" and achieve the purpose of increasing agricultural production and income

(2) the compound environmental friendly degradable liquid mulching film has multiple functions: the heat absorption and warming, moisture conservation and seedling preservation of the existing plastic mulching film; It also has fertilizer effect and medicine effect. The environmental friendly degradable liquid mulching film not only improves the agricultural production environment and eliminates white pollution, but also increases the characteristics of integrating pesticides, fertilizers and agricultural film, causing a lot of inconvenience to patients

(3) the compound environmental friendly degradable liquid mulching film can be turned into the soil with strong adhesion ability, which can connect the soil particles into ideal aggregates, improve the capillary effect of soil particles, improve soil permeability, and become a soil conditioner

(4) spraying film on site saves labor and time. Pesticides and herbicides can be mixed into the film and sprayed together, so as to improve labor efficiency, save labor, and have strong adaptability to terrain and landform

(5) when crops emerge, they can emerge naturally without manual release

II: functional role

(1) improve soil temperature and increase effective accumulated temperature: spraying liquid plastic film can form a layer of dark brown soil on the ground surface and increase the temperature of cm soil by 1-6 ℃

(2) inhibit water evaporation and improve water utilization rate: in order to achieve comprehensive, harmonious and sustainable development, the evaporation inhibition rate is more than 30%, and the soil water content is increased by%

(3) natural degradation, stable operation and elimination of pollution: after spraying the liquid film, it will gradually degrade under the action of light, heat and microorganisms in the soil in about 60 days, and become humic acid organic fertilizer after degradation, fundamentally eliminating white pollution

(4) improve soil physical and chemical properties: after turning and pressing into soil, it can improve soil aggregate structure and soil permeability; It can effectively improve soil hardening caused by long-term use of chemical fertilizers; In addition, it can effectively prevent soil salinization

(5) improve fertilizer efficiency and efficacy: humic acids in mulching film have quinone groups, which can act as plant growth regulators and improve crop stress resistance; The polymer in the film can form chelates and complexes with chemical fertilizers, pesticides, herbicides, etc., making it long-term and stable; In addition, the film itself has fertility and efficacy, and the film can release chemicals with strong bactericidal ability in the process of degradation; The product after degradation is high-quality humic acid organic fertilizer

III: use method

level the land and try to eliminate large debris. Filter the liquid film stock solution with gauze, mix it with water times, and spray the ground evenly with a spray. If the use area is small, you can filter the original solution and mix it with water times, and spray it evenly on the ground with a watering can. Try to avoid trampling and shoveling after spraying. 50kg per mu is recommended for field use
