An innovative technology aiming to promote sustainable development of facility vegetables, the “Facility Vegetable Fully Biodegradable Mulching Film + Total Vegetable Waste Returning to the Field Technique,” has recently garnered significant attention. Through a series of scientific operations, this technology achieves multiple benefits, including reducing the use of ordinary PE mulching films, decreasing vegetable waste pollution, cutting labor costs, and enhancing soil fertility. It demonstrates remarkable economic, social, and ecological benefits, showing promise for widespread adoption in facility vegetable production areas across the province.
The core of this technology lies in the selection and application of fully biodegradable mulching films and the full-scale return of vegetable waste to the field. The choice of fully biodegradable mulching film strictly follows the GB/T 35795 standard, and suitable films are carefully selected based on color, thickness, and service life to meet the needs of different climates, crops, and crop rotations. The technique for returning all vegetable waste to the field involves several critical steps, including greenhouse cleaning, straw crushing, spreading of straw-decomposing inoculum, rotary tilling, high-temperature steaming, and secondary rotary tilling.
According to information from the Color Masterbatch Industry Network, this technology is further enhanced by measures such as selecting high-quality, disease-resistant, high-yield, and efficient varieties, supplementing with biological organic fertilizers, and implementing green pest control techniques. However, there are key considerations during implementation, such as strictly adhering to the selection criteria for fully biodegradable mulching films, avoiding use on crops like strawberries, ensuring the technology is applied during the optimal time of July to August to maximize the effects of high-temperature steaming, and guaranteeing the thoroughness of straw crushing and even spreading of the decomposing inoculum.
Additionally, it’s worth noting that the 5th BDO and Downstream Derivatives Industry Development and Application Forum will be held in Chongqing from August 21st to 23rd. This forum invites upstream and downstream enterprises and related research institutions in the industry chain to discuss industry trends and technological innovations. For enterprises and research institutions focused on sustainable facility vegetable development and the application of fully biodegradable materials, this is an unmissable platform for exchange.
