The leaves are thick, oval, dark green, with a ray of light, the leaves are rounded, the apex is pointed, the leaf is 8.1 cm long, and the leaf is 6.2 cm wide. Petiole 2.96 cm long, purple. Leaf margins are neat, mono-sawtooth and round. The main veins are light green. White flowers, 5 petals, 2 pistils. Stamens 32 to 37 pieces. Anther orange [shielded].
Second, the biological characteristics Shushi Zhongyong, 8-year-old tree height 3.2 meters, 33.3 meters in diameter, dry weeks 26 centimeters, the average new shoot length 76 cm. In the Xiongyue area, buds sprouted in early April, blossomed in mid-April, matured in late July, and fruit development lasted for 95 days. Deciduous leaves in early November, the tree vegetative growth period of about 2l4 days. The germination rate was 44%, the branching rate was 5.6%, and the natural fruit setting rate was 7.7%. The flowering began at 2 years and entered the full fruiting stage from 5 to 6 years old. The result was mainly short fruit branch and bouquet-like fruit branch. The variety has the characteristics of disease resistance, cold resistance, drought resistance, salt and alkali resistance. Natural scab sore disease was 14.3%, the sensitivity index was 3.8; the inoculation rate of artificial inoculation was 23.3%, and the sensitivity index was 5.6. The temperature of the browning of the shoot and the critical temperature of germination and death were both -40°C. Can withstand a short-term low temperature of 33.4 °C, frost resistance is 3 levels.
Third, the fruit traits Longitudinal diameter of 4.98 cm, diameter 4.67 cm, side diameter 4.62 cm, oval, sutures are obvious. The maximum fruit weight is 85 grams and the average fruit weight is 52.5 grams. More than 61% of the big red apricot. The top of the fruit is slightly dimpled, the stems are deep and narrow, the skin is purplish red, the flesh orange is [shielded], and the meat is hard and brittle. The fruit has a hardness of 17.3 kg/cm2, which is resistant to storage and transport. Contains 7.1% of total sugar, 1.6% of total acid, 10.2% of soluble solids, and 9.1 mg of vitamin C per 100 grams. With fine fiber, few juices, and pH 3.0, the variety is separated from the nucleus and its edible rate is 96%. It is not only suitable for fresh food, but also is most suitable for processing into apricot, apricot tea and sugar water perfusion. It has reached the provincial (ministerial) level.
