Causes and remedial measures for the small size of tangerine fruit

Sand sugar orange is a kind of orange variety with great market demand, which has a large planting area in our country and is welcomed by many people. When planting sugar tangerine, if it is not managed properly, it is easy to have small fruit, which seriously affects the yield and commodity value. So what is the reason for the small size of sugar orange fruit? How can it be remedied? Let's take a look at the reasons and remedial measures for the small size of sugar orange fruit with Xiaobian.

1. Nutrient deficiency

1. Reason

Most of the time, the main reason for the small size of sugar orange fruit is due to the lack of nutrients. Too little ditching fertilizer in spring, insufficient amount of topdressing and too long interval of topdressing will lead to the phenomenon of small fruit due to lack of nutrition of sugar orange. And most of the time, it is not because of too little fertilization, but because there is no right fertilizer. For example, when some fruit farmers are topdressing, they will only apply urea, which is nitrogen fertilizer. The application of nitrogen fertilizer alone can only enhance the tree potential of sugar tangerine, but not grow fruit. If the fruit tree has too many branches and leaves, it will rob the growth and nutrition of the fruit, resulting in the phenomenon of falling fruit, small fruit and so on.

2. Remedial measures

Therefore, we should apply fertilizer scientifically, not only to increase the amount of fertilizer, but also to apply fertilizer. Each fruit should absorb comprehensive and adequate nutrients. For example, although nitrogen fertilizer can enhance the tree potential and promote the emergence of tree tops, we should pay attention to the application time of nitrogen fertilizer. When protecting flowers and fruits, the application amount of nitrogen fertilizer should be reduced, and the amount of nitrogen fertilizer can be increased appropriately when putting shoots. When the sugar orange fruit enters the color conversion period, it is necessary to properly apply compound fertilizer and phosphorus and potassium fertilizer to promote fruit expansion and color conversion.

Second, hang too much fruit

1. Reason

Hanging too much fruit is also the main reason for the small size of sugar orange fruit. In order to increase their output, many fruit growers will increase their efforts to protect flowers and fruits. Constantly spraying fruit preservatives, repeated ring cutting and other treetop growth, resulting in too much fruit hanging on the fruit trees. And blindly increasing the amount of fruit is actually very disadvantageous. Hanging too much fruit will lead to insufficient space for fruit growth, nutrition can not keep up with the amount of fruit, and the fruit will be too small because of lack of nutrition.

2. Remedial measures

It is true that you want to increase the yield, but you must control the quantity. The amount of fruit will not only increase the yield, but also affect the sales of fruit and reduce the planting efficiency. Therefore, if you hang too many fruits, you should thinning flowers and fruits in time. Especially after the stable fruit period, artificial fruit thinning should be carried out. In general, the amount of fruit hanging on a branch should not exceed 10 at most, and it is best to keep it at about 5-6. Provide sufficient growth space for each fruit, increase the weight of single fruit, and ensure the commodity value.

The above is a brief introduction of the reasons and remedial measures for the small size of sugar orange fruit. That's all for today's introduction. This article is for reference only. I hope it can help you all.
