Peach trees are deciduous trees, native to the northern and central parts of China, and widely cultivated in various parts of the country. Many plants are cultivated in the north and south of China. Among them, the North China and Chuanyu regions are the most common. It grows wildly in the bushes along the slopes and streams of 500-800 meters above sea level. What are the breeding methods of nectarine? What are the breeding methods of nectarine? Reproduction method: 1. Grafting and reproduction Choose nectarine or mountain peach, cherries, etc. as rootstock. Collect sufficient ripe fruits, wash and dry them after removing the flesh. Around December, stratified sand treatment was carried out. Soak the seeds in clean water for 1-2 days before treatment. Mix the seeds with wet sand in a proportion of 1 - (4-5), stack them in the ditch or keep away from the wind, moisture and ventilation for 100-120 days. When seeds are sowed in autumn, they can be processed without sand. Seeds are generally sowed immediately after soil thawing in spring. Before planting, nursery should be leveled and 1 mX3 to 5 m long. Seedlings or on-demand, seeding depth 4 to 5 cm, spacing of planting plants should be 10 to 12 cm X 40 to 50 cm. Grafting is mostly used for bud grafting. Springs can also be used for grafting. 2, cutting propagation It is divided into two methods: hard branch cutting and soft branch cutting. 1 Hardwood cuttings: During the dormancy period, a robust one-year-old shoot with sufficient light in the upper part of the tree crown was taken, and the branch was cut from the lower part of the canopy, and a section of about 30 cm long was cut off. The lower part of this branch was immersed in 1 ~ 2cm into 1000mg/L of noise-causing butyric acid (IBA) for about 10s, remove the cuttings and inserted into the clean river sand, shade 8 to 10 weeks, and maintain a certain humidity. At the end of this period, when the roots begin to develop, do not make them grow too fast so that they will not be injured in later movements. Afterwards, the cuttings are moved to a 25C hotbed suitable for root growth, and the hotbed can be mixed with 3 parts of coarse sand and 1 part of peat. The long rooted cuttings can be planted directly into the nutrition cup. 2 soft branch cutting: In the growing season, fresh shoots of medium growth potential (avoiding the use of long branches) were cut and cut from the base. Branches with a length of 10 cm were cut off, 3-4 leaves were kept on top, and the leaves were cut in half to reduce evaporation. Immerse the base of the branch in 1000 mg/L of IBA for about 10 seconds. Place it on the perlite substrate. Moisten in a greenhouse or plastic aisle with ventilation cooling measures. Pay attention to proper shading and prevent sunlight at noon. Exposure, while spraying regularly to increase air humidity. After rooting, move into the field and nutrition cup. 3, real reproductive Many peaches have a high rate of self-cultivation, and their offspring have little variation, so many old production areas retain the habit of seed breeding. Such as Gansu Ning County, Zhang Lu Huang Gan pick. Shandong Yidu Qingzhou Peach, Taian, Liaoning Chun Chuntao. However, in the large-scale economic cultivation, it is required that the output be highly commercialized, and if it still adopts actual breeding, the varieties are often mixed. Inconsistent production and quality have seriously affected orchard management and income. Therefore, grafting should still be preferred in economic cultivation.
