[0042] [Examples 1 to 4, Comparative Example]

[0043] When fertilizing fertilizers to blueberry trees, in addition to the compound fertilizer, in the case of the embodiment of the gypsum fertilizer of the composition of the present invention and the comparative example of the non-fertilization of the gypsum fertilizer, the fruit drop rate (%) of the blueberry was measured and confirmed. To the superiority brought by fertilizing the gypsum fertilizer of the present invention. In addition, the gypsum fertilizer used the fertilizer which granulated the powder.

[0044] Specifically, for Examples and Comparative Examples, three blueberries (variety: Emerald, southern highbush) in the same growth state were changed to the fertilizers used for fertilization, and under the same conditions, they were cultivated in pots. , respectively measure the number of fruit set and the number of dropped fruit in each pot, and calculate the rate of fruit drop.

Abstract

The purpose of the present invention is to provide a gypsum fertilizer for blueberries and a method for suppressing blueberry abscission making it possible to suppress abscission of blueberry fruit without adversely affecting growth of the blueberry fruit, and not only increasing the crop yield but also eliminating the need to frequently collect dropped fruits, thus yielding a major practical effect. The foregoing is achieved by a gypsum fertilizer for blueberries that is characterized by containing gypsum having a BSA specific surface area of 15,000 cm2 / g or less as a main component, and a method for suppressing blueberry abscission characterized by the use of the gypsum fertilizer for blueberries.

Description

technical field [0001] The present invention relates to a gypsum fertilizer for blueberries exhibiting an effect of suppressing the shedding of blueberry fruits during fertilization, and a method for suppressing fruit shedding of blueberries using the same. Background technique [0002] Blueberry is a small fruit tree of the genus Vaccinium in the family Rhododendron, and has been eaten since ancient times. In particular, since the beginning of the 20th century, many varieties have been produced through the improvement of varieties of fruit trees based on the hybridization of highbush, rabbiteye, semi-highbush, and lowbush. At present, there are hundreds of varieties. Become the fruit tree that is widely cultivated and eaten widely in the temperate zone of the world. In recent years, in response to the demand, the size of the fruit has also been promoted. Blueberry is an acidophilic and ammoniaphilic plant, and unlike other fruit trees, it grows in acidic soil. Therefore,...
