Citrus fruit fertilizer misunderstanding
The application of a high-quality fruit fertilizer from July to September is a crucial factor in ensuring the quality and stability of oranges. It also serves as an effective strategy to prevent issues like citrus size inconsistency. However, in actual farming practices, many growers have misconceptions about how to apply strong fruit fertilizers, which can be counterproductive and negatively impact both yield and fruit quality. Based on years of experience and lessons learned, the author has compiled some common misunderstandings that need to be addressed.
One major issue is the improper use of nitrogen fertilizer—either applying it too little or too much. In many orchards, urea is heavily used, with surveys showing that over 40% of strong fruit fertilizer applications consist solely of urea. Farmers often apply excessive amounts, such as 500 grams or more per tree, which leads to thickened fruit peels, rough skin, and large but inferior fruits. Additionally, this can delay coloring, result in green fruits, and reduce juice content, making the fruit overly sour and unpalatable. Phosphorus and potassium fertilizers, on the other hand, help reduce acidity and increase sugar levels while promoting fruit expansion. Therefore, it's essential to increase phosphorus and potassium application while controlling nitrogen levels. When needed, adding micronutrients or secondary elements can help achieve balanced nutrition.
For orange trees aged 6–10 years, it's recommended to apply 200–300 grams of NPK fertilizer in July, 2 kilograms of cake fertilizer in September, and 100 grams of urea. For mature trees over 10 years old, the amount increases to 300–400 grams of NPK in July, 3–4 kilograms of cake fertilizer in September, and 200 grams of urea. In red soil orchards, calcium fertilizer should also be applied at around 150 kg per mu, which can boost production by more than 10%.
Another common mistake is using farmyard manure that hasn't been fully decomposed. Unprocessed manures like pig, chicken, or cow dung can generate heat during fermentation, potentially damaging roots and even killing trees. They may also contain parasite eggs, leading to environmental contamination. Moreover, excessive use of raw manure can cause microbial nitrogen buildup. To avoid these issues, manure should be fully composted before application. Cake fertilizer can be soaked in fresh water for 7–10 days or mixed with human waste to enhance its effectiveness.
Improper placement of fertilizer is another problem. Some farmers apply fertilizer directly under the tree canopy, where the main roots are located. These roots are mainly for anchoring the tree, not for nutrient absorption. The fine roots, which are responsible for absorbing nutrients, are concentrated in the drip line area of the canopy. Applying fertilizer under the tree disk may lead to poor absorption and even root damage, especially if chemical fertilizers burn the roots. To avoid this, fertilizer should be placed along the outer edge of the canopy drip line, either in an annular trench or by digging holes slightly deeper. This method ensures better nutrient uptake, avoids root injury, and encourages deeper root growth.
Fertilization without proper irrigation is also a common error. During the dry period from July to September, applying fertilizer without adequate watering can lead to poor absorption and even fertilizer burn. Chemical fertilizers require moisture to break down and be absorbed by the soil. Therefore, it's important to combine fertilization with irrigation. In flatland orchards, trenching and watering after fertilizing is recommended. In mountainous areas, small pits should be dug at the outer edge of the canopy drip line, filled with fertilizer, and then watered to ensure optimal nutrient uptake.
Lastly, improper timing and technique in foliar feeding can reduce its effectiveness. Many farmers spray foliar fertilizers after 10 a.m. or before 4 p.m., when temperatures are high, causing rapid evaporation and potential leaf burn. Spraying only the top of the leaves also limits absorption. To maximize benefits, foliar sprays should be done early in the morning or late in the afternoon, preferably on cloudy days. Leaves have stomata that absorb nutrients more effectively than the surface, so thorough coverage, including the underside, is essential for maximum efficiency.
