Fertilization Precautions and Key Planting Techniques for Shatang Mandarin
What should be noted when fertilizing Shatang mandarin? Please give guidance. During routine visits to rural areas, I found that quite a few farmers fertilize Shatang mandarin unreasonably. The following are listed for reference: One-sided and excessive application of nitrogen fertilizer: urea is the most commonly used in production. According to surveys, in recent years, mandarin orchards that applied urea alone as the fruit-fattening fertilizer accounted for about 40%, and it was applied arbitrarily, often resulting in excessive amounts; for example, applying more than 500 grams of urea per tree is not uncommon. One-sided and excessive application of nitrogen fertilizer causes the peel to thicken and become coarse, forming inferior thick-skinned large fruit; coloring is delayed, and a large number of green fruit appear; the flavor deteriorates and the juice rate declines, especially making the taste sour and astringent, unpalatable. Phosphorus and potassium fertilizers have an obvious effect in promoting fruit acidity reduction and sugar increase, and can promote the expansion of citrus fruit.

What climate suits the Shatang mandarin? A detailed guide to planting and management methods
Selection of climate conditions and planting management for the Shatang mandarin 1 Selection of climate conditions The Shatang mandarin has a certain level of requirements for climate conditions; general cultivars require annual rainfall of 1,200-2,000 mm, an annual average temperature of 18-21°C, and an absolute low temperature that must be above -5°C. At the same time, the adequacy of sunlight needs to be fully guaranteed, and the land must be strictly selected and controlled. To ensure the growth benefits of the Shatang mandarin, the organic matter content needs to be ensured at above 1.5%, while also ensuring good water retention and drainage performance, with the groundwater level below 1 m; the thickness of the soil layer and the looseness of the soil texture should have an active soil layer of more than 1 m, while the pH value should be controlled at 5.5-6.5, and the best soil types are sandy loam, paddy soil, and alluvial soil. In addition, during the planting process of the Shatang mandarin, it is also necessary to ensure the water source, conditions for irrigation, and the transportation environment.
