Problems solved by technology

[0003] Miracle fruit belongs to sun plants, and flowers bloom in most months of the year. However, due to the dry autumn, it is conducive to the flowering and fruiting of miracle fruit. Therefore, the full flower and fruit period is in autumn, and there are a small amount of fruit in summer, but most of them fall off before they are ripe; In a shady environment, the miracle fruit can also survive, but it does not bear fruit; the main factor affecting the fruit setting is the ambient humidity. The air humidity is high, and the fruit is easy to fall off. In an environment with low air humidity, the miracle fruit can bear fruit in most months, and the temperature in winter is lower than Easy to frostbite at 2 degrees
The rooting rate of the propagation method of miracle fruit cuttings is lower, and it is urgent to provide a method for raising seedlings of miracle fruit cuttings with high rooting rate

Abstract

The invention relates to a miracle fruit seedling raising method, which comprises the following steps of: (1) cutting piece treatment: selecting thick and strong miracle fruit tree branches with vigorous growth of more than two years and a cutting piece length of 15-20cm as cutting pieces, spraying a mixed solution of cytokinin and naphthylacetic acid on the cutting pieces, and continuously spraying the mixed solution for more than 1-2 times to obtain cutting pieces; (2) cuttage treatment: sterilizing the cutting pieces by using a disinfectant, and inserting the treated cutting pieces into aseedling raising substrate arranged in a greenhouse; (3) post-cuttage management: keeping the temperature in the greenhouse at 25-30 DEG C and humidity at 70-95%, and controlling the shading rate at 70-80% by covering a shading net; (4) transplanting management: transferring the rooted cutting pieces into a pot for culturing, laying moss on the soil surface of the pot for decoration, carrying outshading by using a 50% shading net, wherein the culture temperature is 25-32 DEG C and the humidity is 70-95%. The method provided by the invention has the following advantages: (1) the rooting time of the miracle fruit cutting pieces is shortened by 3-5 days; and (2) the rooting rate is high and can reach 97% or more, the survival rate of the cutting pieces is high, and the decay rate is low.

Description

technical field [0001] The invention relates to a method for propagating fruit trees, in particular to a method for raising seedlings by cuttings of miracle fruit. Background technique [0002] Miracle fruit is a typical tropical evergreen shrub, native to West Africa, Ghana, and Congo. In the 1960s, miracle fruit began to be cultivated in my country. [0003] Miracle fruit belongs to sun plants, and flowers bloom in most months of the year, but due to the dry autumn, it is conducive to the flowering and fruiting of miracle fruit, so the full flowering and fruiting period is in autumn, and there are a small amount of fruit hanging in summer, but most of them fall off before they are ripe; In a shady environment, the miracle fruit can also survive, but it does not bear fruit; the main factor affecting the fruit setting is the ambient humidity. The air humidity is high, and the fruit is easy to fall off. In an environment with low air humidity, the miracle fruit can bear frui...
