These benefits can be seen not only in broad beans, but also in other legume crops; and whether it is ordinary plastic film or degradable film, it can generally give similar effects. Film can keep moisture in the soil and buffer sudden changes in temperature. This is especially critical for legume production in areas with unstable rainfall, drought or cold. Film can extend the growing season of crops and reduce water shortage pressure, ultimately leading to more stable and higher yields. Higher water use efficiency and more survival of seedlings also make the entire legume planting system more risk-resistant and sustainable. Farmers want to save water and labor on the film in the broad bean field; officials are more concerned about not piling up a pile of white garbage. Therefore, degradable films were pushed to the forefront - not perfect, but at least they can really dissolve without leaving residue. Some people worry whether changing to new materials will affect seedling emergence? After several rounds of trials in the field, germination and yield did not fall behind, and the amount of irrigation also decreased. The problem turns to the other side: the technology cannot keep up, farmers do not know how to use it, and the effect is discounted. Instead of blindly shouting slogans, it is better to spend money on research and development and training: how to make the material more stable, how to lay the film more conveniently, and it is best to compile a manual so that front-line workers can understand it. When monitoring equipment, climate models and precision fertilization are all connected to the same network, the water-saving account, output account, and environmental account of the film can be clearly seen at a glance, so that promotion will not take two steps forward and one step back.
