What about nitrogen deficiency in figs?

Fig is a kind of fruit which belongs to subthermal deciduous small trees and grows in tropical and temperate zones. Although it is called fig, the fig tree has amazing 50 points, luxuriant branches and high ornamental value. it is now the first choice for greening in many cities and gardens, and it is also used as a potted plant. But in the current planting process, farmers apply little or no nitrogen fertilizer in order to prevent the growth of fruit trees from being too dense. If it leads to serious nitrogen deficiency in fruit trees, what should we do about nitrogen deficiency? What are the symptoms of nitrogen deficiency? Let's take a look at it.

1. Symptoms of nitrogen deficiency

In the process of planting figs, we should pay close attention to the fig tree potential or leaves, if the leaves grow poorly, the color of the leaves is relatively dim, the leaves gradually crack, and gradually tend to the whole leaf shape, the leaf edge will start to roll up, with the hands will feel more brittle, thicker. Nitrogen deficiency will cause different symptoms of branches and fruits, slow down the growth rate of branches, and lack of nutrition in tree roots, resulting in a serious lack of nutrition in fruits, leaves and branches, resulting in a substantial reduction in yield. it will also have a great impact on the economic interests of farmers.

2. The effect of nitrogen deficiency

Fig needs more nutrition in the process of growth, water and fertilizer, although nitrogen deficiency in the early stage does not do much harm to the tree and has little effect on the root development of the tree. However, in the later stage, with the increase of nitrogen deficiency time, the degree of nitrogen deficiency will be aggravated, which will hinder the root development of fruit trees, and cause root rot to be easily harmed by root aphids, resulting in branches unable to accept the effects of early aging and stop growth. Nitrogen deficiency will also reduce the number of inflorescence differentiation on the tree, and the transverse diameter of the fruit will become smaller, although it will mature earlier and have better quality, but nitrogen deficiency will transfer the nutrients in the leaves to the fruit, and the leaves visible to the naked eye will fade, causing serious fruit drop and reducing yield.

3. Prevention and control methods

It is found that when fruit trees are fertilized immediately after nitrogen deficiency, although the growth of branches will gradually recover, the fruit will begin to turn brown and black, and fruit drop will occur. People will think that this is harmed by organic acids, but the harm of organic acids will not fade the leaves, the veins will bulge, and the harm of organic acids is faster and more serious than nitrogen deficiency. Therefore, if nitrogen deficiency is found, the fig orchard should be fertilized and improved, and fully mature organic fertilizer or commercial organic fertilizer should be added to the soil to improve the nutrients in the soil, because the root is the foundation to ensure the nutrition of the whole tree. and the first one to transport. Therefore, this is the fundamental measure to solve nitrogen deficiency, and reasonable nitrogen supplement to prevent long-term nitrogen deficiency in trees to meet the nutrients needed by trees.

Now the fig market is very large, the price is also very considerable, is the fruit with high profit. Therefore, in the process of planting, we must pay attention to the symptoms of nitrogen deficiency in figs, if so, we must deal with them in time, for the final yield and for their own economic interests. However, the supplementary application of nitrogen fertilizer can not be excessive, excessive nitrogen fertilizer will also have a certain impact on fruit trees, which will lead to excess nutrition in the trees and easily lead to the phenomenon of falling flowers and fruits.
