The reasons for the uneven size of the latest citrus fruits

In the citrus autumn shoot growth period, it is also the last expansion period of the fruit, but at this time there is a phenomenon of uneven fruit size, which can not be improved at this time. If the fertilizer and water management is strengthened, the big fruit will appear floating skin. So what is the reason for the size of citrus fruits? Let's get to know it.

1. Direct cause

In the first physiological drop period of citrus, the young fruit did not drop, or very little, until the second physiological drop, the large fruit and small fruit fell together, so the remaining young fruit was large and small, resulting in serious fruit size in the later stage. If the first physiological fruit drop is normal, then the bad fruit will fall, and the rest of the normal young fruit will be relatively uniform. The main reason for little or no fruit drop in the first physiological fruit drop is that there are flowers without spring shoots, and the tree nutrients are concentrated on the fruit, which affects the normal fruit drop in the first physiological fruit drop.

2. Indirect causes

In the control of winter, due to improper use of chemicals, too high concentration or too many times, it will cause flowers and shoots in spring. In addition, for the plants with weak tree potential, the phenomenon of flowers without shoots is also more common, and it is also very easy to have no flowers in spring shoots if the tree is too prosperous, and there are many reasons for the weak tree potential, such as lack of nutrients, damage to the root system and so on.

3. Preventive measures

In the fruit expansion period, the lack of nutrients, the most prone to lack of fertilizer from May to July, when there is generally no fertilization or less fertilization, afraid of a large number of spoons, while the tree is lack of nutrients, it is easy to form large and small fruits seriously. Can be added at the beginning of flowering is a Xie flower, potash fertilizer and high-quality water-soluble fertilizer match. When spraying winter shoot control agents, paclobutrazol + potassium dihydrogen phosphate should be sprayed alone, mainly spraying autumn shoots 1-2 times, which is relatively safe, not suitable for whole plant spraying, weak trees, fruit trees with large fruit quantity and late shoot release should be sprayed once or not.
