Problems with Bio-Degradable Mulch FilmThe following problems existed in the bio-degrading mulch:
1. ** In terms of tensile strength **: Due to the characteristics of the basic material itself, most of the tensile strength of the bio-degrading mulch film is not enough. In the agricultural areas where mechanical work is the main work, it is impossible to carry out mechanized film coating operations. This problem is particularly prominent in the Xinjiang region.
2. ** In terms of controllable decomposition **: There are problems with the cracking and controllable decomposition of most of the films. A large number of experiments have shown that the cracking and decomposition of the existing films are too early, and the covering time is much shorter than the safety period of the film covering crops, resulting in its function not being able to be fully utilized.
3. ** Warming and moisture preservation performance **: Most of the films had different functions compared to ordinary PE films. The water preservation test results of the simulation test showed that the water preservation of the films was obviously inferior to that of PE films.
4. ** In terms of product cost **: The high cost of the bio-degrading film is a factor that limits its large-scale application. On the one hand, it was necessary to reduce the price of degraded products through the large-scale production of raw materials and the improvement of formulas. On the other hand, the cost of using the plastic film should be comprehensively evaluated to promote the large-scale application of the plastic film.
5. ** In terms of environmental protection **: Currently, there is not enough evidence to prove its environmental protection. From the perspective of soil, studies showed that although the negative impact of LDPE film residue on soil properties and corn productivity was higher than that of full-degrading film residue, the degrading film had a greater negative effect on soil structure and nutrients.

What is the method of using the degrading material in the mulch?When using the bio-degrading plastic film, first of all, one week before covering the plastic film, the irrigation farmland should be ploughed and fertilized. The ploughing depth should be 30 cm. For example, when planting processed tomatoes, 16 kg of nitrogen fertilizer, 20 kg of phosphorous fertilizer, and 16 kg of potash fertilizer should be applied per mu. In the middle of April, a film mulch machine was used in the irrigation of the farmland, covering a 120 cm wide biochemical film every 30 cm, and at the same time, ridging was made, the ridge height was 10 cm, and the ridge width was 150 cm. The periphery of the biochemical film was covered by a machine, the film was mechanically covered with soil, and a drip irrigation belt was laid under the film. Transplanting was carried out when the water content of the soil in the irrigation farmland was 22% and the soil temperature was greater than or equal to 10 ° C. For example, the processed tomato seedlings were provided with nutrient matrix, one plant per hole, transplanted in the middle and late April, two rows were planted in each ridge, the plant spacing was 30 cm, and the row spacing was 25 cm.
The field application operation steps of the full-degrading mulch film include soil preparation and ridge forming, mulch film laying, film punching, irrigation, fertilizer application, weed control, and post-treatment. It is advisable to choose a plot with convenient irrigation and drainage, sufficient water source and loose soil structure, and operate according to the moisture content during sowing. At the same time, there were differences in the choice of mulch color for different purposes. For the main purpose of preventing grass, black mulch should be selected; for the main purpose of increasing temperature, colorless transparent mulch should be selected, especially for early spring planting in northern regions. In addition, suitable bio-degrading mulch film products should be selected according to the crops in the region to avoid situations such as insufficient weather resistance and water resistance, premature decomposition and rupture that could not meet the needs of crops such as moisture preservation and heat preservation, or slow decomposition that would affect the next crop cultivation.

Delivery-delivery transmigrationThere were many settings in online novels that involved delivering food. For example, some protagonists traveled back in time to the ancient times and became takeaways. For example, although there was no online ordering in the Tang and Song Dynasties, there were restaurants that provided takeaways. Modern people might have traveled back in time to participate in it. There were also ancient characters such as princes and princes who traveled back in time to the modern world to deliver takeaways. There were also strange settings such as the delivery boy transmigrating to the ancient country of women while delivering food. There were even plots where the protagonist had to face all kinds of magical creatures and powerful mages as a delivery boy after transmigrating. In addition, there were novels like " Infinite Transmigration Delivery ".

Is the order delivery an e-commerce or express delivery?Delivery was an important part of e-commerce operations and was closely related to the express delivery business. In the e-commerce scene, merchants sent goods to consumers through logistics methods such as express delivery. Placing an order meant that the merchant would generate the express delivery form and other relevant documents according to the order information, while shipping meant that the goods would be handed over to the express delivery company for transportation and distribution. Therefore, ordering and shipping were both in the scope of e-commerce operations and involved the express delivery business process.

Fast DeliverySpeedy Express was an integrated logistics service model that was featured by speed. It mainly provided same-day delivery, same-day delivery, and special errand services. However, Speedy Express also received some negative comments. Some people called it trash, and the employees were hooligans. They weighed the goods randomly and didn't show it to you face to face. In addition, there was also a business simulation game called " Fast Delivery ". Players needed to transport goods on the runway, calculate the shortest time and the best route, and earn money. Speedy Express was also the name of a Korean movie. It was starred by Su Zhitan and told the story of a special driver who was involved in an accident. The search results did not provide a clear answer to the question of which express delivery company Speedy Express belonged to.
