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.
