No.: Chuanju Fruit Tree 2008005
(1) Breeding (Introduction) Units: Institute of Horticulture, Sichuan Academy of Agricultural Sciences, Economic Crop Management Station of Aba Prefecture Agricultural Bureau, Guoshu Station of Agricultural Bureau of Hanyuan County, Yaan City, College of Forestry and Horticulture, Sichuan Agricultural University, Life Science of Southwest University of Science and Technology College of Engineering.
(2) Variety source: Introduced from Dalian Institute of Fruit Science (formerly Dalian Institute of Agricultural Sciences) in the 1980s
(3) Characteristics: The tree vigor is strong, the erection of the young tree is strong, the mature tree is half open, the germination rate is high, the branching force is strong, the leaves are large, the ellipse shape is wide, and the shoots are drooping on the shoot. Flowering buds are large and full, with long fruiting branches in the young fruit trees. Fruiting results are mainly in bouquet fruit branches and short fruiting branches. Fruits are kidney-shaped, large, well-defined, fruit stems are short, and fruit peels are red to purple. , shiny. The average fruit weight of 9.0 grams, the fruit soluble solids content of 15.1% -19.1%, total sugar content per 100 grams of pulp 10.0-13.8 grams, total acid 0.43-0.81 grams, edible rate of 91.3%-95.7%. The flesh is hypertrophic and the juice is sweet and juicy. The pollination varieties are Jiahong, Juhong, Hongmi, and Rabins. Mature period (Aba state in mid-May, Yuexi county from the end of April to early May, Hanyuan in mid-May, Guangyuan city in early May) is more than 1 month earlier than the origin of Liaodong Peninsula, 20 to 30 days earlier than Shandong Peninsula . Early maturity, strong adaptability and stress resistance.
(4) Yield performance: Gisela No. 5, No. 6 and No. CAB6 were used as root stocks. The results of the third-year test of the grafted seedlings after planting were taken. The yield was 1.0-3.0 kilograms; the first five to seven years entered the period of full production with a yield of 15.0- 30.0 kg. The second year of high tree accession trials, the results of the first three years of strain production 5.0-12.5 kg, the first year of strain production 15.0-20.0 kg, the fifth year into the high yield period, the strain produces 25.0-30.0 kg, rich yield per mu up to 1200 kg.
(5) Cultivation points: 1 It is recommended that the spacing of the plants should be 3 meters and 5 meters. Choose a deep soil layer and a high content of organic matter. Drain well the slightly acidic sandy soil to build a garden, ditches, or planting holes to plant soil; 2 According to the 1:4 configuration Pollination varieties; 3 organic fertilizer, N, P, K with. After the fruit stage, the fertilizer and water management will be strengthened. The basal fertilizer will be re-used before the annual defoliation, and the quick-acting fertilizer will be applied immediately before flowering, after flowering and during fruit expansion. The fertilization in autumn accounted for 70% of the annual fertilization amount; 4 The pruning was trimmed into a spindle shape and a Y shape. The saplings should be plucked many times to promote branching, expand the crown, and open the angle by pulling branches to ease the tree vigor and advance the results; 5 Comprehensive prevention and control of pests and diseases: in the control of appropriate period of application, do a good job in field monitoring, the use of pollution-free low-toxic, low-residue pesticides.
(6) Suitable areas for planting: Sichuan is planted at a high altitude of 1000-2200 meters.
