Breeding method of red fruit (basic knowledge): the best growing soil: red fruit is suitable for growing in sandy soil with rich humus, loose and fertile soil and good drainage.
Requirements for growth humidity: Water red fruits frequently during the growth period, do not dry the pot soil, and often spray water on the plants and the surrounding environment to increase the air humidity of the surrounding environment.
Optimum growth temperature: red fruit is not resistant to high temperature. If it is higher than 35℃ for a long time in summer, you can properly shade and ventilate to cool down. In winter, potted plants can be buried in outdoor sunlight or put in a cold room at 0℃ to 10℃ for wintering.
Optimum growth light: red fruit seedlings are generally transplanted or potted every spring, and sufficient sunshine is needed during the growing period. If the light is insufficient, it will affect the color, plant shape and fruit. Therefore, ground planting can be planted in sunny and ventilated places in the courtyard, while potted plants should be placed in sunny places.
Matters needing attention in red fruit breeding: Fertilization: Nitrogen fertilizer can be appropriately increased in the early stage of red fruit growth, and should be controlled or stopped after June, and the application amount of phosphorus, potassium fertilizer and trace elements such as calcium and magnesium should be increased to improve fruit quality and ornamental effect, enrich branches and promote flower bud formation.
Key points of watering: keep the soil moist and free of water during the growth period of red fruits. June is the flower bud differentiation period every year, so it is necessary to control watering for 2 ~ 3 weeks, and then water when the young leaves wither to promote the formation of flower buds.
Pruning essentials: Prune and reshape the plant once before the germination of red fruits in spring, cut off diseased dead branches, cross branches, over-dense branches and long branches, and shorten the long branches to facilitate ventilation and light transmission and keep the tree beautiful.
Pot soil replacement: Generally, red fruits are replaced once every 1 ~ 2 years before germination in spring. Potted soil can be 65,438+0 humus soil and 0.5 coarse sand, and a small amount of hoof pieces or decomposed animal manure can be added as base fertilizer.
Key points of breeding: sowing method is adopted, and spring and autumn are suitable periods. Take out the seeds, wash them and bury them in loose soil. It can germinate in about 3 weeks, and after about 1 year, the seedling height is more than 15 cm. In addition, young plants growing from the rhizosphere of mother plants can often be found on the ground near the plants, or they can be dug and planted. Red fruits have straight roots and few fine roots. When transplanting, we should pay special attention to digging deep and try to avoid root cutting, so as not to affect the survival rate of transplantation.
Sowing: When the fruit is ripe, you can pick the seeds and sow with the harvest. After sowing, keep the soil moist, sprout in about 40 days, and transplant in the next spring.
Root cutting: spring can be combined with pot changing, and thick roots can be cut off for cutting, with high survival rate.
Pest control: there are few pests and diseases of red fruit larvae, but sometimes there are anthracnose, scale insects, beetle adults, butterfly larvae and other pests and diseases, which should be prevented in time.
Experience in breeding red fruits: (1) Put them under the germination shed in summer to prevent the sun from shining to the south, otherwise the leaves will turn yellow. To keep the air moist and dry, the leaves will turn yellow, which will make the plants grow poorly and difficult to bear fruit.
(2) In spring and autumn, applying thin fertilizer once every 3-4 weeks, 1 time, can make plants grow vigorously and leaves green. We should apply more phosphorus and potassium fertilizer and control the amount of nitrogen fertilizer, otherwise too much nitrogen fertilizer will grow leaves in vain and it will be difficult to blossom and bear fruit. It is best to apply phosphate fertilizer at the late flowering stage.
(3) In addition to keeping the soil moist in summer, watering should not be frequent in spring and autumn, and it is advisable to dry it slightly, and watering should be controlled in winter.
(4) Change pots in April every year, apply sufficient base fertilizer, cut off old leaves, and make new leaves grow vigorously and propagate in parallel, with 4 buds per pot.
