Problems solved by technology

[0002] Among the existing technologies, agricultural plastic mulch is the most commonly used. Its disadvantages are: 1. It cannot be degraded permanently when it is covered on the field. , thus causing huge pollution to the soil and the environment
2 It can only be used before the seeds are sown and green shoots grow, and it is not easy to use after the green shoots grow, so there are great limitations in use
3. There are few functions, and it can only play a few functions such as simple heat preservation and antifreeze. In general, the disadvantages outweigh the advantages
Another kind is the degradable mulch that has appeared in recent years. Although it can be degraded and is environmentally friendly, it still has many disadvantages: 1. The cost is high and the cost performance is low, which is difficult for the market and farmers to accept.
2. It can only be used before the seeds are sown and the green shoots grow. It is not easy to use after the green shoots grow, so there are great limitations in use
3. There are few functions, and it can only play a few simple functions of heat preservation, antifreeze and degradability

Embodiment 1

[0024] Take 80 kg of chopped fresh and tender plants, 20 kg of chopped insect-proof and disease-resistant grasses, mix and stir the above-mentioned raw materials in proportion, fix them with a greening machine and knead them so that the plants are cross-linked and intertwined with each other, and then roll them into corresponding Thickness and specifications of plastic film are packaged into cylinders for later use, and can be directly covered on the field when used. Form a strong mesh multifunctional mulch film on the ground, which has excellent functions such as heat preservation, moisture retention, sun protection, antifreeze, insect protection, soil loss prevention, disease resistance and sterilization, weeding and ventilation, fertilizer increase, and improvement of soil hardening. 1 It begins to rot and degrades naturally in about a month. The organic fertilizer liquid formed during the rot and degradation process fertilizes the crops, and finally the rotten plant fertili...

Embodiment 2

[0026] Take 80 kilograms of chopped fresh and tender plants, 20 kilograms of chopped insect-proof and disease-resistant grasses, mix and stir the above-mentioned raw materials in proportion, fix them with a greening machine and knead them into roll-shaped granules, and then pack them for later use. When in use, sprinkle the granular degradable plastic film evenly on the field or on the field with growing crops, as long as the soil is completely covered, the roll-shaped granular biodegradable plastic film will It swells and bounces across, forming an interlinked and intertwined mesh multifunctional mulch film on the ground, which has excellent heat preservation, moisture retention, sun protection, antifreeze, insect protection, soil loss prevention, disease resistance and sterilization, weeding, Breathable, fertilizing, improving soil compaction and hardening, etc. It will slowly rot and degrade naturally in about one month. The organic fertilizer liquid formed during the rot de...

Embodiment 3

[0028] Take 90 kg of short-cut fresh and tender plants, 5 kg of short-cut insect-resistant and disease-resistant grasses, and 5 kg of environmentally friendly glue. Mix and knead the above raw materials in proportion so that the plants are glued to each other by the environmentally friendly glue, and then roll them into corresponding Thickness and specifications of plastic film are packaged into cylinders for later use. When used, they can be directly covered on the field, forming a solid mesh multifunctional plastic film on the ground, which has excellent heat preservation, moisturizing, sun protection, antifreeze and insect protection. , anti-soil loss, disease resistance and sterilization, weeding, ventilation, fertilization, improvement of soil compaction and hardening, etc., it will slowly rot and degrade naturally in about one month, and the organic fertilizer formed during the decay and degradation process will increase fertilizer for crops, and finally Rotting plant man...

Abstract

The invention discloses a multifunctional degradable plastic mulching film and a production method thereof. The multifunctional degradable plastic mulching film comprises raw materials in percentage by mass as follows: 10%-100% of short-cut fresh and tender plants, 0-90% of insect-resistant disease-resistant grass, 0-30% of environment-friendly glue, 0-30% of glue powder and 0-50% of an auxiliary comprising farmyard manure, the raw materials are mixed in corresponding ratio, stirred, fixed by a fixation machine and rolled until the plants are cross-linked and wound mutually, then the materials are ground into the plastic mulching film with corresponding thickness, specification, shape and series by a film laminator and packaged for standby application, and a field is directly covered by the plastic mulching film during use. The firm net-shaped multifunctional plastic mulching film formed on land surface has the excellent functions of heat insulation, moisture preservation, sunscreen, antifreezing, insect prevention, soil erosion prevention, disease resistance, weeding, ventilation, fertilization increase, improvement of soil hardening and the like.
