Sandy Beach
A sandy beach soil is known for its good aeration and quick nutrient decomposition, which supports a well-developed root system. However, it tends to be shallow, with poor water and nutrient retention. This can lead to unstable water and fertilizer supply, making trees more prone to weakness. When excessive fertilizers are applied, the well-developed roots and good air permeability may cause short-term vigorous growth. For example, after autumn, heavy natural rainfall can trigger rapid growth of new shoots, but due to the high root density, nutrients are quickly depleted, leading to leaching and loss. As a result, nutrient deficiency often occurs after the rainy season, causing early leaf drop. In addition, alluvial plains and sandy beaches frequently suffer from issues like a sticky layer and a high groundwater level. To improve these conditions, large amounts of organic matter and clay should be added to enhance the soil's ability to retain water and nutrients. It's also important to break up the sticky layer, lower the groundwater level, and plant cover crops in trenches to help improve soil structure.Mountainous Land
Soil on mountainous land is typically thin and has good aeration, but it suffers from severe drought and soil erosion, with poor water and nutrient retention. Trees often grow slowly, with small, yellow, and brittle leaves, resulting in low productivity. Deficiencies such as zinc and boron are common. To address this, a large amount of organic fertilizer should be applied to improve soil fertility and water-holding capacity. Before planting, soil and water conservation measures like terracing should be implemented. Deep plowing and soil thickening can help correct nutrient deficiencies, allowing fruit tree roots to grow deeper and improving their drought resistance and nutrient absorption capabilities.Saline Soil
Sweet cherries have specific pH requirements, with an ideal range between 6.0 and 7.5. If the soil pH exceeds 7.8, soil improvement is necessary. Coastal areas are generally favorable for sweet cherry growth, but the soil often contains varying levels of salt and alkali. One effective method is to dig trenches before planting and fill them with 20–30 cm of crop stalks to create a buffer zone that prevents salt from rising to the surface. Applying large amounts of organic fertilizer can help lower the soil pH. When using potassium fertilizer, potassium sulfate is preferred, and ammonium sulfate is better for nitrogen. These practices help block capillaries, reduce evaporation, and minimize salt accumulation in the topsoil. Using mulch, ground cover, and planting green manure crops can further improve saline soils.Limestone Foothills, Alluvial Plains, Clay Soil
These soils have good water and nutrient retention but poor permeability, leading to limited root development, low density, and issues like waterlogging during the rainy season. Long-lasting autumn shoots and early leaf drop in the middle and lower parts of the tree are common problems. Before planting, deep application of organic fertilizer and the addition of sand or gravel can improve soil permeability. Drainage ditches should also be dug to manage excess water effectively.Imported Premium Coating Additive
Coating auxilliaries, also known as paint accessories, the department of the preparation of coating auxiliary materials, can improve coating performance, promote the formation of coating film. There are many kinds, including drying agent, toughening agent, emulsifier, thickening agent, pigment dispersing agent, defoaming agent, levelling agent, anti-skidding agent, matting agent, light stabilizer, mildew proofing agent, antistatic agent (see plastic assistant), etc., among which the largest amount is drying agent and toughening agent. At present, the research of coating auxilaries, to be used for water emulsion paint auxilaries as the focus.
