Myrica rubra is a small evergreen dioecious tree or shrub, also known as Shengmei, Baitimei or Shu Mei. It is mainly produced in temperate regions such as Hunan, Guangdong, Guangxi and Guizhou, with an altitude of 120 ~ 1500m and a latitude of 20 ~ 3 1 degree north, and belongs to subtropical humid climate.
It blooms in February and ripens in May. It is named Yangmei because it is shaped like poplar and tastes like plum. Myrica rubra is favored by fruit farmers because of its long economic life and high planting efficiency under normal soil, fertilizer and water management conditions.
Spraying boron fertilizer during the fruit expansion period of Myrica rubra can make the fruit full, increase the yield, reduce the acidity and increase the sweetness. This measure is one of the effective measures to increase production and increase efficiency in the process of high and stable yield planting of Myrica rubra.
Benefit of spraying boron fertilizer on waxberry fruit during its swelling period.
① Spraying boron fertilizer is helpful to improve the sugar content of Myrica rubra.
When bayberry trees can't absorb boron nutrition from soil or use boron fertilizer effectively, the carbohydrate in bayberry plants will be disordered, and the transportation and accumulation of sugar in plants will be hindered, so it is impossible to accumulate in bayberry fruits.
Therefore, spraying boron fertilizer during the fruit expansion period of Myrica rubra can help the fruit increase and accumulate sugar, which has the effect of sweetening.
② It can improve the physiological activity of Myrica rubra root system, promote its root growth and development, strengthen plants and improve fruit appearance and quality.
Spraying boron fertilizer during the fruit expansion period of Myrica rubra can promote the growth and development of plant roots and improve the content and activity of indoleacetic acid in Myrica rubra plants. It not only has fruit expansion effect on Myrica rubra fruit in that year, but also is beneficial to flower bud differentiation in the next year.
(3) It can reduce the cork of Myrica rubra, prevent the fruit from bursting, and reduce the added value of commodities.
The formation of pectin in Myrica rubra is related to the content of boron and ribonucleic acid. When the RNA in Myrica rubra fruit is insufficient, the pectin in Myrica rubra plant will decrease correspondingly, which will lead to the increase of cellulose in the fruit, making Myrica rubra taste like a cork and have poor palatability.
At the same time, the phloem parenchyma cells and general parenchyma cells of Myrica rubra fruit will thicken, and when the growth of internal and external pulp is inconsistent, Myrica rubra fruit will burst, thus losing commodity value and reducing planting income.
abstract
Calcium and boron can promote sugar metabolism and fruit expansion together; The sweetness of fruit is directly proportional to the calcium content. Calcium can effectively reduce the content of titrated acid in fruits and improve the sweetness. In this way, bayberry will be big and sweet when it matures.
