What's the reason why the apple is small?

Apple is a kind of fruit that many people like very much, which is distributed all over our country. Because apple has extremely high nutritional value, can supplement human nutrition, promote digestion and so on, so the planting area in our country is also very large. When growing apples, it is very common for apples to be small. This will seriously affect the quality and efficiency of apple. So what is the reason why the apple is small? Let's take a look at it.

1. Leave too much fruit

When planting apples, we do not pay attention to the work of thinning flowers and fruits, and control the load of apple trees. Also did not grasp the proportion of leaves and fruits, resulting in too much fruit of apple trees. On the other hand, the apple tree is unable to meet the growth and development of all fruits because of its limited nutrition. Causes the fruit to become smaller because of insufficient nutrition. The more fruit is left, the more dispersed the nutrition will be, affecting the speed of cell division. Therefore, there will naturally be a phenomenon of small fruit. Therefore, it is necessary to remove the excess flowers and fruits in time, avoid excessive nutrition consumption, and improve the size, chromaticity and sugar content of the fruit.

2. Environmental factors

The weather is very disadvantageous to the growth of apples from July to August every year. July is a sunny day with high temperature and drought. If it is not treated in time, the fruit will stop growing. On the other hand, it is rainy in August, and there is no drainage, which is prone to waterlogging, and the roots will breathe anaerobically. Affect the absorption of nutrition and water by apple tree roots. The fruit will also become smaller because of lack of nutrition and moisture. Therefore, in these two months, we should not only do a good job of watering drought prevention, but also timely drainage, and reasonable fertilization, can effectively make up for small fruit problems.

3. Improper pruning

The pruning of apple trees is very important, but there are many problems in many orchards, such as leaving too many branches, tree potential imbalance, orchard closure and so on. Poor ventilation and lack of light lead to strong and weak apple trees, resulting in outward movement of the fruit parts, resulting in too small fruit in the lower branches of the fruit trees. In addition, when cultivating the fruiting branch group, do not cut it lightly and put it long. Otherwise, the distance of nutrition transport will be too long and the consumption will be too large, thus affecting the results. Therefore, when pruning, we must pay attention to balance the growth potential of the main branches between plants to ensure that the yield is balanced and easy to manage.

4. Lack of nutrition

The nutrient storage in the tree is the key to the size of the fruit. If there is no timely fertilization or insufficient fertilization, improper proportion of nutrition, then it will affect the nutrition accumulation of apple trees, and it is also a common problem in many orchards. Some fruit growers want to be able to leave more fruit, but do not want to invest too much, resulting in apple trees are often undernourished, the tree is too weak, resulting in small apples. When fertilizing, chemical fertilizer, especially high nitrogen fertilizer, can not be applied for a long time, which can easily lead to excessive growth of branches, thus affecting the expansion of apples, resulting in small and green apples.

The above is a brief introduction to the small reasons for Apple. That's all for today's introduction. This article is for reference only. I hope it can help you all.
