The causes and remedial measures of the latest sugar orange fruit being too small

Satang orange is a kind of orange variety with great market demand. It has a large planting area in China and is welcomed by many people. When planting sugar orange, if the management is improper, it is easy to appear the phenomenon of small fruit, seriously affecting the yield and commodity value. So what is the reason for the small fruit of sugar orange? How can we remedy this? Let's take a look at the reasons and remedies for the small fruit of sugar orange together with Xiaobian!

1. Insufficient nutrients

1. Reasons

Many times the main reason for the small fruit of sugar orange is caused by insufficient nutrients. Too little ditching and fertilization in spring, insufficient topdressing dosage and too long topdressing interval will lead to lack of nutrition and small fruit of Satangju. And many times it is not because of too little fertilizer, but because there is no fertilizer. For example, some fruit growers will only apply urea when topdressing, and urea is nitrogen fertilizer. Only nitrogen fertilizer can strengthen the tree vigor of Satang orange, but can not grow fruit. If there are too many branches and leaves of fruit trees, they will rob the growth and nutrition of fruits, resulting in fruit drop, fruit small and other phenomena.

2. Remedy measures

Therefore, we should apply fertilizer scientifically, not only to increase the amount of fertilizer, but also to apply fertilizer. Let each fruit absorb full and sufficient nutrients. For example, although nitrogen fertilizer can enhance tree vigor and promote tree growth, attention should be paid to the application time of nitrogen fertilizer. The amount of nitrogen fertilizer should be decreased when flower and fruit were preserved, but increased properly when shoot was put out. When the fruit enters the color transformation period, compound fertilizer and phosphorus and potassium fertilizer should be appropriately applied to promote fruit expansion and color transformation.

2. Too many fruits

1. Reasons

Too much fruit hanging is also the main reason for the small fruit size of Satangju. In order to improve the yield, many fruit farmers will increase the efforts to protect flowers and fruits. Continuous spraying of fruit protectants, repeated ring cutting and other tree growth, resulting in excessive fruit on the fruit tree. And blindly increasing the amount of fruit is actually very unfavorable. Too much fruit will lead to insufficient fruit growth space, nutrition can not keep up with the amount of fruit, fruit will also be too small because of insufficient nutrition.

2. Remedy measures

It was true that he wanted to increase the yield, but he had to control the quantity well. If the fruit quantity was high, it would not only not increase the yield, but also affect the sales of fruits and reduce the planting efficiency. Therefore, if there are too many fruits, it is necessary to thinning flowers and fruits in time. Especially after the stable fruit period, artificial thinning should be carried out. Under normal circumstances, the number of fruits on a branch should not exceed 10 at most, and it is best to keep it around 5-6. Provide sufficient growth space for each fruit, increase single fruit weight and ensure commodity value.
