Plasticizer is widely used in industrial production of polymer materials, also known as plasticizer. Any substance added to a polymer material that increases the plasticity of the polymer is called a plasticizer. Plasticizer can improve the performance of polymer materials, reduce production costs and increase production benefits. [1] is a kind of important additives, chemical products as additives commonly used in plastics, concrete, mortar, the material such as cement, gypsum, cosmetic and detergent, especially in PVC plastic products, in order to increase the plasticity of the plastic and improve the strength of the plastic, you need to add phthalic acid ester, sometimes its content can be up to 50% of the products. Weakened the effect of plasticizer mainly resin molecular valence bond between time, increase the mobility of the resin molecular bonds, reducing resin molecular crystalline, increase the plasticity resin molecules, enhanced the flexibility, easy to machining, can legally used for industrial purposes, widely exists in food packaging, cosmetics, medical equipment, water and environment. Such as plastic wrap, food packaging, toys and so on.

Winter season lawn management over the summer
In the northern regions, most lawns are composed of cool-season grasses that naturally go into dormancy during the summer months, especially in early-maturing varieties. During this period, the lawn's metabolic activity slows down significantly, and its resistance to stress is weakened. Without proper maintenance, this can lead to patchy bald spots or even large areas of dead grass, which greatly affects the overall appearance of the landscape.
Pruning during the summer dormancy should be done carefully. Since growth is slow, the frequency of mowing is reduced. It's important to follow a few key guidelines:
1. Avoid frequent mowing. It’s best to mow every two to three weeks, not more often. Over-mowing can damage the base growth points and may cause the lawn to deteriorate over time.
2. Maintain the correct cutting height by following the “one-third†rule—never cut more than one-third of the grass blade at a time. In shaded areas, it’s advisable to raise the cutting height slightly to help the grass thrive under lower light conditions.
3. Avoid repeating the same cutting pattern or using dull blades. This can cause uneven wear and stress on the grass, leading to poor regrowth and an unattractive lawn.
Soil aeration and rolling are essential for maintaining a healthy lawn. Aeration improves soil porosity, allowing better water and nutrient absorption, while rolling helps compact the soil and promote denser turf growth. Combining both practices ensures strong, healthy grass, reduces weed growth, and keeps the lawn looking vibrant.
1. Vertical mowing is typically done in late summer or early autumn. This involves cutting vertically through the thatch layer to improve air circulation and root development.
2. Core aeration is best performed in early summer. Holes are drilled into the lawn at intervals of 15–20 cm, and the removed soil is replaced with coarse sand to enhance drainage and root penetration.
3. Rolling should not be done alone but combined with mowing using a roller weighing around 200 kg. This helps firm the soil without damaging the grass.
Watering is crucial for maintaining a healthy lawn, especially during hot weather. Water loss occurs through surface evaporation, leaf transpiration, and soil moisture depletion. To ensure optimal hydration:
1. Water early in the morning or in the evening, but be cautious of disease risks if watering in the evening. Fungicides can be applied if necessary. Avoid watering during midday heat, as this can scorch the grass and is hard to reverse.
2. Increase the depth of each watering session rather than the frequency. Aim to moisten the soil to a depth of 15 cm. Watering two to three times per week is generally sufficient, though more frequent watering may be needed in arid climates.
3. Ensure proper drainage by creating a slight slope (around 2%) on the lawn. If water accumulates in certain areas, manually drain them to prevent root rot and other issues.
Fertilization and pesticide application should be avoided during the hottest days of summer. However, if the lawn shows signs of nutrient deficiency, a solution of 0.5% urea and 0.5% potassium dihydrogen phosphate can be applied. Fertilize every two weeks, and combine it with pest control. Always apply sprays evenly and avoid mixing different pesticides unless necessary. Use insecticides and fungicides separately to prevent chemical interactions and ensure effectiveness.
