The method of propagation of mysterious fruit

Mysterious fruit is a tropical evergreen shrub of Oleaceae, also known as tarnished fruit, which is native to West Africa, Ghana and Congo. It is hot and humid, and the suitable temperature for growth is 20: 30 ℃. It is planted in the field with good drainage, rich in organic matter and acidic sandy soil with a pH value of 4.5-5.8. The main propagation methods are sowing, cutting and high-pressure propagation. Let's take a look at the breeding methods of mysterious fruit.

Mysterious fruit sowing and propagation

The seeds are picked to the fresh and ripe fruit, peeled, washed and disinfected with sand before sowing, not suitable for long storage, about 300 grains per square meter, covered with fine sand 2 cm, keep the sand bed moist, about 15 days, the germination rate can reach more than 100%. After the seedlings are unearthed, 0.2% urea or potassium dihydrogen phosphate is sprayed once a week, when the seedlings are 6 cm high and 4 leaves grow, then transplant to the nursery for further management. Prepare the seedbed before sowing and use clean, loose soil for the substrate. Spread or sow in the seedling bed, cover soil 2 cm after sowing, control temperature 26-28 degrees Celsius, keep the culture soil moist, and sprout in 60-80 days. When the seedlings have 4-5 true leaves, they can be planted with soil balls in flowerpots or nutrition bags filled with culture soil for culture and management, and the seedlings grow slowly.

Mysterious fruit cuttage propagation

Mysterious fruit cuttage propagation in April to June cut the semi-lignified or completely lignified branches of the same year as cuttings, about 15cm long, retain the upper part of the cuttings 1x3 leaves, each leaf cut off 1 2, cut the lower end of the cuttings cut into an axe-shaped 45-degree slope, and soak the cuttings in fumigant solution (NAA1000 mg per liter, 5000 times) for 3 minutes, then insert it in clean sandy soil. The treatment of mysterious fruit cuttings with hormone can not only promote rooting, but also have high rooting rate, early rooting and early new leaf buds, which is obviously better than that of direct cutting. The cutter should maintain a suitable relative humidity of more than 80% and a shade condition of 75%. It can take root in about 50-60 days, and the rooting rate is 70%. After the new root is formed, it is transplanted into a nutrition bag and maintained in the nursery. The cuttings can end early and dwarf the tree shape. Or soaked with 863 rooting powder solution to promote its rooting.

High pressure propagation of mysterious fruit

The mature branches of 1 ~ 2 years old with strong growth were selected for high pressure propagation from April to July for striping treatment, and rooting could take place in 60 ~ 70 days. The length of the high-pressure ring is 3cm to 4cm. The upper and lower edge of the ring should be neat, deep to the xylem, peeled and scraped off the cambium. Due to the hard wood of the mysterious fruit, it is difficult for the air strips to take root, and the success rate of reproduction is low. Therefore, at the ring cutting place, the prepared rooting powder 500mg per liter or IBA500 mg per liter was evenly sprayed on the cultivation substrate, and the humidity of the substrate was pinched into a mass by hand. Wipe the rooting water on the ring peel mouth with cotton, squeeze the matrix into fist size, wrap the matrix on the ring peel mouth with plastic film, check the moisture condition once every 10 days, and find that the syringe can be injected with water when it dries. When the new root grows to yellowish brown, the high-pressure branches can be cut off and planted in nutrition bags or flowerpots to maintain a certain degree of shade and humidity. Before planting, it is necessary to gradually reduce the concealment of pseudo-planted seedlings.
