Why do we need to use enlarging agent?

In the early stage of ripening of bayberry, some fruit-preserving medicine is given, and it is given dozens of days in advance. In the later stage, no pigment is used at all. As long as the weather is good, the bayberry will be black. It will get darker later if it rains.

Expanding agent! A kind of growth hormone! If it is needed for academic, scientific research or planting, it is recommended to use it with caution.

The following is a method to make bayberry fruits bigger without using pesticides:

(1) Choose good varieties and strengthen management

To produce big fruits For bayberry, you must first choose large-fruited bayberry varieties, such as Dongkui bayberry, Ding'ao bayberry, etc. If you want the fruit color of bayberry to be purple-black, you must choose varieties such as water chestnut bayberry and Ding'ao bayberry. If you want bayberry to mature early, you should choose varieties such as early chestnut honey plum and early color.

After the variety is determined, the cultivation technology will also affect the size, color and maturity period of the bayberry fruit.

①Rational fertilization. Bayberry is a potassium-loving fruit tree. It is necessary to apply more potassium fertilizer, less phosphorus fertilizer, and appropriate nitrogen fertilizer every year to provide nutrients for large and high-quality fruits.

②Pruning and shaping. For existing adult bayberry trees that have been left to grow unchecked, the trunk and main branches can be gradually transformed into a dwarfed, open-shaped crown by adopting the methods of "cutting high branches and controlling the crown" and "deleting inner branches and opening skylights", which can make the crown more ventilated and ventilated. Good light also plays a certain role in thinning flowers, and the fruits are large and of good quality.

③Chemical control. The use of bayberry flower thinning agent can reduce the fruit setting rate of bayberry during the flowering period, thereby increasing the weight of single fruit and improving the quality, so as to achieve large, good quality and high unit price of bayberry fruits in the big year; the fruit set of bayberry in the young year will increase, the fruit will be larger, and the economic benefits will increase.

④Artificial fruit thinning. For big-year bayberry that has too many fruits, shake the flowers first and then thin out some of the young fruits, leaving 1-2 fruits on one fruiting branch.

(2) Optimize the habitat and pick at the right time

The color of bayberry fruits comes from pigments, the environment in which bayberry grows (such as light, mineral nutrients, etc.), the growth and development of the tree body and the fruit The stage and physiological state will all affect the formation of pigments in bayberry fruits. The three properties of pigments, total acid, and soluble solids in the fruit are interrelated. As the color change and color value of the fruit increase, the maturity of the fruit increases, the color continues to deepen, the total acid content of the fruit continues to decrease, and the soluble solids gradually accumulate. When the fruit is fully mature, its color value, soluble solids and solid-acid ratio reach the highest value, and the total acid content reaches the lowest value. After understanding the relationship between the changes in pigments and main contents of bayberry fruits during the color change process, we can know that in order to make bayberry fruits shiny, we must first grasp the harvest maturity of bayberry fruits; secondly, improve the environmental conditions for bayberry tree planting and strengthen the tree. Body management can promote the change of color and value of bayberry pigments, so that the luster of bayberry fruits will be brighter.

The ripening period of bayberry fruit is closely related to temperature, moisture, sunshine, soil, topography, topography, altitude, etc. To make bayberry fruits mature early, you must first choose low hills and hills with gentle terrain and slightly acidic soil; the soil is loose and moist, has good drainage, contains gravel and is rich in organic matter to promote the growth of the tree and achieve early fruiting, high yield and high quality of bayberry. . Second, promote greenhouse cultivation technology to promote early maturity of bayberry. Greenhouse facility cultivation can increase the ambient temperature for the growth and fruiting of bayberry trees, thereby advancing the maturity of bayberry trees.
