What fertilizer is best for bayberry fruit expansion? (What fertilizer should be applied during the bayberry fruit expansion period to make it big and sweet)

Bayberry is an evergreen dioecious small tree or shrub, also known as Shengshengmei, Baidimei or Shumei. It is mainly produced in temperate and subtropical humid climates such as Hunan, Guangdong, Guangxi and Guizhou, with an altitude of 120 to 1500m and a north latitude of 20 to 31 degrees.

It blooms in February and matures in May. It is named as bayberry because it looks like a water yam and tastes like plum. Bayberry has a long economic life and high planting efficiency under normal soil, fertilizer and water management conditions, and is favored by fruit farmers.

Spraying boron fertilizer during the fruit expansion period of bayberry can make the fruit fuller and increase the yield , and it can also reduce the acidity and increase the sweetness. This measure is one of the effective measures to increase production and efficiency in the process of high-yield and stable production of bayberry.

The benefits of spraying boron fertilizer during the fruit expansion period of bayberry

① Spraying boron fertilizer can help increase the sugar content of bayberry fruit

When the bayberry tree cannot absorb boron nutrients from the soil or cannot effectively utilize boron fertilizers, the carbohydrates in the bayberry plant will be disordered, the transport and accumulation of sugar in the plant will be hindered, and it will be impossible to accumulate in the bayberry fruit.

Therefore, spraying boron fertilizer during the fruit-swelling period of bayberry can help the fruit increase and accumulate sugar content, thereby enhancing sweetness.

②It can improve the physiological activity of the roots of bayberry trees, promote their root growth and development, strengthen the plants, and improve the appearance and quality of the fruit

Spraying boron fertilizer during the fruit expansion period of bayberry trees can improve the growth and development of the plant's root system and increase the content and activity of indoleacetic acid in the body of bayberry trees. It not only has an effect on the fruit expansion of the bayberry fruit of the current year, but is also beneficial to the differentiation of flower buds in the following year.

③ It can reduce the cork formation of bayberry fruit and prevent the bayberry fruit from bursting, thus reducing the added value of the product.

The formation of bayberry pectin is related to the content of boron and RNA. When the RNA in the bayberry fruit is insufficient, the pectin substance in the bayberry plant will be reduced accordingly, resulting in an increase in cellulose in the fruit. Such bayberries will taste like cork and have poor palatability.

At the same time, the phloem thin-walled cells and general thin-walled cells of the bayberry fruit flesh will thicken. When the growth of the inner and outer flesh is inconsistent, the bayberry fruit will burst, thereby losing its commercial value and reducing the planting income.

【 Summarize 】

Calcium and boron together can promote sugar metabolism in fruits and promote fruit expansion; the sweetness of fruits is proportional to the calcium content. Calcium can effectively reduce the titratable acid content of fruits and increase sweetness. In this way, bayberries will be big and sweet when they are ripe.
