Plastic Mulch Film

Promote the germination of seeds. For the seeds of crops to grow, the first step is to germinate. After the crop is harvested, the seeds go dormant. As a self-protection mechanism of the seed, dormancy allows the seed to keep itself in a healthy state for as long as possible before encountering a suitable growth environment. In the planting process, if the seeds are allowed to germinate on their own, one of the time required is too long, and the other is that the dormancy time of different seeds is not consistent, then the budding time is not consistent, and eventually the seedlings grow differently, which adds difficulty to field crop management. Therefore, in order to make the seedling growth more consistent, we need to promote the seed germination treatment. For seeds to sprout quickly, soil moisture and temperature conditions need to be good enough. After the plastic mulch film is covered, due to the shelter, the heat and water in the soil are not so easy to dissipate, thus playing a certain role of insulation and moisture, and speeding up the germination and emergence of seeds.

Warm winter, protect seedlings in winter. Many crops need to go through a cold winter in the growth process, if you do not pay attention to warmth during this period, in the face of extreme cold weather, it is very easy to occur seedlings frostbite and freeze to death, and ultimately greatly reduce the final yield of crops. The plastic mulch filmhas a good thermal effect and can help the seedlings winter to a certain extent.

Prevent rain wash, reduce fertilizer loss. At different growing points of the crop, farmers need to apply varying amounts of fertilizer. If it catches up with the rainy season at this time, these fertilizers are easily washed away by rain and lost, and the crops cannot use these fertilizers, thus losing the significance of topdressing and causing waste. After covering the plastic mulch film, it can not only prevent the erosion of the fertilizer by the rain to a certain extent, but also improve the utilization efficiency of the fertilizer by reducing the volatility of the fertilizer itself.

Improve soil and improve crop yield and quality. Plastic mulch film can improve soil moisture and temperature conditions, which in turn can indirectly provide a good living environment for microorganisms in the soil, strengthen soil microbial activities, facilitate the decomposition of organic matter in the soil, and then improve soil structure, increase soil fertility, and ultimately improve the growing environment of crops and improve crop yield and quality.

Improve the efficiency of crops to use light. After growing to a certain height, there will always be a shaded part between the crops and the ground, which will affect the normal growth of crops that require higher light conditions. The plastic mulch film can reflect light, which means that in the sunlight, some of the light reaching the ground can be reflected out. This has a good effect on the growth of the plant part that is close to the ground and does not get sunlight for a long time, so that the upper and lower parts of the plant can develop together, which is conducive to the overall growth of crops.

Inhibit the growth of weeds, weaken the harm of diseases and insects. Covered with opaque mulching film can make the ground weeds and insects difficult to grow due to insufficient light conditions. The transparent mulching film can affect the growth of weeds and pests to some extent by regulating the soil climate environment.
