Cultivation method for promoting flower bud differentiation of Syzygium samarangense

Abstract

The invention discloses a cultivation method for promoting flower bud differentiation of Syzygium samarangense, which comprises the steps: lightly pruning 70-80 days before a flower forcing day is regulated in the production period of Syzygium samarangense; on the next day after the light pruning work is finished, spreading the mixture of calcium superphosphate and potassium chloride near crown drip lines once every 15 days, with spreading performed four times in total; on the seventh day after the ground fertilization work is completed, sprinkle-irrigating the plants with a mixed solution fertilizer of monopotassium phosphate and potassium chloride once every 15 days; and on the seventh day after the ground fertilizer spreading work is finished, spraying the whole trees with a mixed solution of monopotassium phosphate and auxins until the leaf surface drips once every 15 days, with spraying performed 5 times in total. When the plants are in a state of declining vigor and leaves hang down, the other operations are carried out according to the normal flower forcing technology of a Syzygium samarangense orchard. The method and fertilizer element matching are scientific and efficient,the implementation is simple and feasible, the implementation cost is low, the effects of inhibiting nutrient growth and promoting flower bud differentiation are obvious, and the method is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to a method for cultivating lotus mist, in particular to a cultivation method for promoting differentiation of lotus mist flower buds. Background technique [0002] Syzygium javanica belongs to Myrtaceae (Myrtaceae) and is a typical perennial evergreen tropical fruit tree. It is bright in color, sweet and delicious, and is deeply loved by consumers. In the 1990s, lotus mist has developed into one of the most important characteristic economic fruit trees in Taiwan. In the past two decades, the lotus mist planting industry has been actively developed in southern provinces such as Hainan, Guangxi, Fujian, and Guangdong. At present, it has developed into a A regional characteristic industry that increases agricultural efficiency and farmers' income in hot areas. [0003] Because the supply of high-quality lotus mist fruit is in short supply in the consumer market, its price is high (average price 30-50 yuan / kg), and it is favored by ...

AI Technical Summary

Problems solved by technology

[0005] ①The existing techniques for slowing down plant vegetative growth and promoting flower bud differentiation are complicated, and the input cost of labor and agricultural materials is high

[0006] ② The effect of flower bud differentiation and transformation is not good, which is manifested in the small amount of flowers and irregular flower buds after flowering

[0007] ③A large amount of chemical fertilizers are applied on the ground, causing the physical and chemical structure of the land to be destroyed and the link to be polluted

[0008] ④ Excessive inhibition of vegetative growth, resulting in too weak a tree, affecting the yield and quality of the next year

The disadvantage is that the input of a large amount of phosphorus and potassium fertilizers will cause the deterioration of the physical and chemical structure of the land, the acidification of the land, and the pollution of the environment.

In addition, in case of high temperature and rainy weather, the inhibitory effect is poor, and the effect of flower prompting is unstable.
