Problems solved by technology

[0004] Miracle fruit is propagated with seeds, cuttings, air layering and other methods, mainly by planting. Miracle fruit grows slowly, and generally only blooms and bears fruit after 3-4 years after planting, and the survival rate of seeds is not high, which seriously restricts the quality of miracle fruit. reproduction

Abstract

The invention discloses a method for promoting the germination of miracle fruit seeds and improving the survival rate of seedlings, which is mainly realized through steps such as seed selection, seed disinfection, ultrasonic treatment, seed dormancy breaking treatment, seed germination, and seedling transplantation; The technology of breaking seed dormancy by using growth regulator control and variable temperature treatment, including the use of appropriate concentration of growth regulators and suitable variable temperature treatment substrates and temperature changes, greatly shortens the germination time of miracle fruit seeds. The invention uses ultrasonic waves to treat seeds, and adopts appropriate temperature and light treatment to improve the germination rate, germination potential and germination index, and adopts a suitable seedling raising substrate, and the survival rate of seedlings is also high.

Description

technical field [0001] The invention relates to a method for releasing the dormancy of miracle fruit and improving the survival rate of seedling cultivation. Background technique [0002] Miracle fruit belongs to the mysterious genus of Sapotaceae. It is a typical tropical evergreen shrub. It is native to West Africa, Ghana, and Congo, and it is also found in the jungles of Indonesia. In the 1960s, when Premier Zhou Enlai visited West Africa, the Republic of Ghana gave the mysterious fruit to Premier Zhou as a national gift. Since then, the miracle fruit began to be cultivated in our country. Miracle fruit is a precious plant of national treasure level. No matter it is in West African countries or my country, it is protected and its export is prohibited. [0003] The reason why the miracle fruit is mysterious is that it can change people's sense of taste, so people feel that any sour food after eating the miracle fruit is sweet. It turns out that there are many taste buds...
