Broadly speaking, stabilizing chemicals that increase the stability of solutions, colloids, solids, and mixtures are called stabilizers. It can slow down reactions, maintain chemical equilibrium, reduce surface tension, and prevent light, thermal, or oxidative decomposition. Generalized chemical stabilizers come from a wide range of sources, mainly according to the design purpose of the formula designer, you can flexibly use any chemical to achieve the purpose of product quality stability.

Speaking in a narrow sense, it mainly refers to maintain the stability of polymer plastics, rubber, synthetic fiber, etc., to prevent its decomposition, aging reagent.
Winter season lawn management over the summer
Most lawns in northern regions are composed of cool-season grasses, which naturally go into a dormant state during the hot 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. If proper maintenance is not maintained, it can lead to patchy bald spots or even large areas of dead grass, which seriously affects the visual appeal of the landscape.
Proper mowing during the summer dormancy period is essential. Since growth is slow, the frequency of mowing should be reduced. Here are some key tips for effective mowing:
1. Avoid frequent mowing. It’s best to mow every two to three weeks. Over-mowing can damage the growth points at the base of the grass and may lead to lawn degradation.
2. Follow the “one-third†rule when cutting. Never remove more than one-third of the grass height at once. In shaded areas, it’s advisable to raise the cutting height slightly to help the grass thrive under less sunlight.
3. Avoid repeating the same mowing pattern. Use a sharp blade and vary the direction of mowing to prevent compaction and uneven growth.
Soil aeration and rolling are important practices that complement each other. Aeration improves soil porosity, allowing better water and nutrient absorption, while rolling helps to press the turf down, promoting denser growth and a healthier lawn. Combining both techniques ensures strong, uniform growth and helps suppress weed development.
1. Vertical pruning involves cutting into the soil surface to loosen it and improve air circulation. This is typically done in late summer or early autumn.
2. Core aeration is best performed in early summer. Drill holes 15–20 cm apart, remove the soil cores, and fill them with coarse sand to enhance drainage and root development.
3. Rolling is usually done in conjunction with mowing using a roller weighing around 200 kg. It should not be done alone, as it may cause unnecessary stress to the grass.
Watering is crucial but must be done carefully. The water requirement of the lawn includes surface evaporation, leaf transpiration, and moisture loss through soil pores.
1. Water early in the morning or in the evening, but be cautious of disease risk if watering in the evening. Fungicides can be applied if needed. Avoid watering during midday heat, as it can scorch the grass and cause long-term damage.
2. Increase the depth of watering rather than the frequency. Each session should moisten the soil to a depth of at least 15 cm. Water two to three times a week, and increase the frequency in drier climates.
3. Ensure proper drainage by maintaining a slope of about 2% on the lawn. If water accumulates in certain areas, manually drain it to prevent root rot and other issues.
Fertilization and pesticide application should be avoided during the hottest days of summer. However, if the lawn is severely nutrient-deficient, a solution of 0.5% urea and 0.5% potassium dihydrogen phosphate can be applied. Apply it every two weeks, and always combine it with pest control. When spraying, ensure even coverage and avoid mixing different pesticides unless necessary. Always follow instructions carefully to prevent harm to the lawn.
