The reason why the latest apple is small.

During the apple harvest season, many fruit growers find that their apples are small and do not grow big, which has a great impact on the yield and seriously damages the economic interests of farmers. So what is the reason for Apple's small size? Let's take a look.

1. Excess fertilization

Generally speaking, the weight of a normal apple is about 200 grams, but when some fruit growers apply too much fertilizer in the planting process, it is very easy to cause a large number of flowering in the sprouting period, and then it is not timely to do a good job in thinning flowers and fruits. It is extremely easy to cause excessive nutrition consumption of fruit trees in the expansion period, tree absorption can not keep up with plant consumption, and finally the phenomenon of falling flowers, fruits and small fruits will be formed.

2. Influence of diseases and insect pests

Fruit will inevitably suffer from diseases and insect pests in the process of growth, if Apple Yuan does not pay attention to the daily pruning, the orchard environment is closed, humidity, then bacteria and insect pests will occur in large numbers. For example, red spider and leaflet disease will cause great harm to apple leaves, seriously cause leaf shedding and affect the normal supply of beekeeping plants, which will have a certain impact on the formation of small fruits of apples.

3. Fertilizer abuse

When fertilizing apples, the quality of fertilizer application can play a very important role, and the abuse of this fertilizer refers to the imbalance of various nutrients. Orchard fertilization should pay attention to balanced fertilization, not only to supplement a large number of elements, but also pay attention to the supply of small trace elements, so as to ensure yield and quality. If a large amount of nitrogen fertilizer is usually applied, it will cause excessive plant growth, branch growth and fruit expansion to compete for nutrients, resulting in small fruit size and poor color. In addition, the application of too much nitrogen fertilizer before adoption will also affect the plant storage nutrients, although it will not affect the yield of the current year, but it will have a serious impact on the growth of fruit trees in the coming year.

4. Climate impact

In some areas, apples are generally small because of climatic factors. in the cloudy and rainy weather of apple ripening for a continuous month, the leaves can not carry out photosynthesis, and the nutrients of the trees are exhausted, resulting in very few nutrients of the trees. it seriously affected the formation of post-anthesis cells in the second year, resulting in generally small apples.
