With the expansion of citrus planting area, more and more growers choose to apply more chemical fertilizers in order to quickly increase yields, but ignore the input of farm fertilizer. The old citrus orchards are replaced by a large number of chemical fertilizers due to the lack of organic fertilizers. The result is a noticeable decrease in the sweetness of the citrus, a greater acidity, and a worse flavor.
So, how should we restore the sweetness of citrus?
Proper calcium supplementation is very necessary. This is because the lack of calcium will cause the sugar content of the fruit to accumulate insufficiently. In the citrus growing areas of southern China, most of the soil is red, and this red soil often has a certain acidity. It is this acidic soil that makes it difficult for citrus plants to absorb calcium. Therefore, we can choose to use "sweetener" foliar fertilizer, which is a fertilizer formulated with a mixture of calcium, boron, sucrose and plant growth regulators. In the form of foliar sprays, citrus can be provided with the nutrients it needs.
In addition, it is also important to use potassium dihydrogen phosphate foliar fertilizer rationally. Potassium dihydrogen phosphate is a water-soluble binary compound fertilizer that can be directly absorbed by citrus leaves by foliar spraying. In general, potassium dibasic phosphate is configured at 0A concentration of about 2% is sufficient. Doing so not only improves the sweetness of the citrus, but also enhances the stress resistance of the citrus and increases the yield.
In addition, we can also consider changing the timing of fertilization in winter. Experiments have shown that the application of basal fertilizer immediately after the autumn harvest of citrus fruits will significantly improve the yield and quality of the orchard in the second year compared with the orchard that waits until winter to fertilize again. Therefore, timely fertilization is one of the important factors to ensure the sweetness of citrus.
These are some of the ways to fertilize citrus sweetness, but we can't just stop at the technical level. In addition to fertilization techniques, we should also pay attention to the ecological environment of the soil and the accumulation of soil organic matter. More organic matter can improve soil structure and increase the soil's ability to retain water and fertilizer, thus providing good growing conditions for citrus.
Therefore, for the problem of insufficient sweetness of citrus, we cannot simply blame the wrong fertilization method and stop exploring. Only by working together on both the ecology and the fertilization method can we solve this problem and restore the sweetness and beauty of citrus.
The story is not over, Zhang Farmer of a certain farm adopted the above method, and he found that the sweetness of citrus has increased significantly, not only his own citrus has been well received, but also attracted the attention of the surrounding villagers. He feels that his citrus is more competitive than ever, that his sales are more open and that his income has increased significantly.
It was the success of this practice that made him believe that as long as every citrus tree is treated with heart and fertilized with scientific methods, the quality of citrus will be guaranteed. Therefore, he decided to share these experiences and methods with other growers, hoping to help more people solve the problem of poor citrus quality.
Looking at the scene of a citrus orchard glittering, Farmer Zhang's heart swelled with indescribable joy. He thought that as long as he persevered and met every challenge in the future, his farm would become more and more prosperous, and the reputation of citrus would become more and more famous.
So, he continued to move forward, with his love and dedication to citrus planting, composing a solemn and exciting song of the development of the citrus industry.
