morphological character
The red fruit tree of Rosaceae is a small shrub with a height of 1 0m. Dense branches; Branchlets are thick when young, densely villous, and gradually fall off. Leaves oblong, oblong-lanceolate or oblanceolate, 5 ~ 1.2 cm long, acute or acute at the apex, cuneate or cuneate at the base, entire, concave at the upper part of midvein, grayish brown pilose along midvein, compound corymb, 5 ~ 9 cm in diameter, and many flowers; Petals nearly round; Anthers purplish red; The top of ovary is tomentose. The fruit is nearly spherical and orange-red. Flowering in May-June; The fruiting period is 9 ~ 1 o months.
Garden use
Ornamental fruit trees are suitable for planting in gardens or hillsides.
Cultivation method of red fruit trees
1, fertilizer and water
During the growth period of winter red fruit, the soil should be kept moist without water accumulation. June is the flower bud differentiation period every year, so watering should be controlled for 2 ~ 3 weeks, and then watering should be carried out when young leaves wither to promote the formation of flower buds. In order to improve fruit quality and ornamental effect and enrich branches, it is beneficial to the formation of flower buds. Timely removal of tender shoots at the top of branches, prevention of branch elongation and redistribution of nutrients are beneficial to fruit development.
2. Lighting equipment
After potted plants, Dong Hongguo can be kept in a sunny and well-ventilated place. Dong Hongguo needs plenty of sunshine during its growing period, which will affect the color, plant shape and fruiting of fruits.
3. Temperature
If the summer temperature is higher than 35℃ for a long time, you can shade and ventilate properly to cool down. In winter, the winter red fruit flowerpot is buried in the outdoor sun or in the cold room at 0℃ to 10℃ for wintering.
prune
Before germination in spring, prune and shape the winter red fruit, cut off the diseased dead branches, cross branches, over-dense branches and long branches, and shorten the excessively long branches, so as to facilitate ventilation and light transmission and keep the tree beautiful. Change pots every 1 ~ 2 years before spring planting. Potted soil can be rich in humus, loose and fertile sand with good drainage.
5. Grafting method
1, scion picking
The new shoots with normal growth in the middle and periphery of the crown and full buds were selected as scions from the mother plants of winter red fruit trees. The new shoots were robust, free from pests and diseases, with high yield and high quality. After cutting the scion, immediately cut off the leaves, leaving only a petiole of 0.3 ~ 0.4 cm, and keep it moist. Scions should be transported outdoors and wrapped with plastic sheets to prevent water loss; In spring grafting, ears should be picked after autumn and stored for winter.
