Causes and prevention methods of premature senescence of the latest navel orange

Navel orange is loved by the public because of its delicious taste and rich nutrition. with the expansion of market demand, its planting area is getting wider and wider. In recent years, the phenomenon of premature senescence of navel orange is becoming more and more obvious, which seriously affects the yield and quality of navel orange, so how to prevent premature senescence of navel orange? Let's take a look.

1. Symptoms of premature senility

When the navel orange has premature senescence, the leaves decrease, the leaf color is dim and dull, the trunk is grayish brown, fungi and old branches die in the trunk with serious premature senescence, although there are many flowers, but the quality of the fruit is poor. And the good root system will appear the phenomenon of dry peeling, and the new root is less.

2. Pruning branches

According to the specific situation of premature senescence of navel orange, the diseased branches can be pruned properly, and the pruning choice is more suitable in spring, and the new branches will sprout again after pruning. Except for some plants with severe premature senility, other degrees of premature senility can be recovered by pruning. At the same time, when planting restoration trees begin to hang fruit, it is necessary to reasonably control the number of fruits. If there are too many fruits, premature senescence may continue in the next few years. Once repeated premature senescence occurs, it will be difficult to recover until the plant dies.

3. Rational irrigation

Water plays a very important role in the growth of navel orange, and reasonable control of watering water has a good effect on the prevention and treatment of premature senescence of navel orange. It is necessary to keep the soil water content reasonably according to the actual growth situation of navel orange, and pay attention to the rainy period in summer, when the precipitation is relatively large, when the soil water content far exceeds the needs of navel orange growth, it is necessary to dig trenches in time for drainage, reduce soil water content, and create a loose and breathable soil environment for navel orange growth.

4. Scientific fertilization

Improving the fertilization method of navel orange is also one of the important measures to prevent premature senility. the traditional fertilization method is mainly to apply fertilizer next to the plant, but now fertilizer should be mixed with organic fertilizer and compound fertilizer, and how to mix organic fertilizer and compound fertilizer into a certain amount of water. in retting, when it is deep after maturity, the nutrient of the imrefined fertilizer is more, and it is easy to be absorbed by the navel orange.

The above are the reasons for premature senescence of navel orange and the introduction of prevention and treatment methods, hope to help you, want to know more related knowledge, please pay attention to us.
