1. Propagation method
There are many propagation methods of nectarine, such as cutting, sowing and grafting. If grafting propagation is adopted, then the rootstock should choose peach and other varieties. The success rate of self-pollination of peaches is relatively high, so we generally don't need artificial pollination. If you want to improve the quality of nectarine, change its characteristics. Then we can mix it with other nectarines when planting, and enhance the variety of fruit by artificial pollination. When selecting varieties, we should choose them flexibly according to soil conditions, local market demand and local climate.
2. Land selection and preparation
Nectarine is suitable for growing in thick and soft organic soil. Therefore, when we build a garden, we should prepare the soil. First, turn over the soil about 25 cm deep, then finish the fine harrow and expose the soil to the sun for about three days to eliminate the germs in the soil. When preparing soil, it should be applied together with base fertilizer to improve soil fertility. Because the root growth ability of nectarine trees is relatively strong, attention should be paid to regular intertillage and weeding when planting to ensure sufficient water permeability of the soil and provide sufficient growth nutrition for nectarine trees.
3. Water and fertilizer management
Nectarine has a great demand for growth and nutrition, so it is not only necessary to apply sufficient base fertilizer before planting. Topdressing should start from the second year after planting, and the quantity and types of fertilization should be controlled according to the tree potential and age. For example, when young trees are topdressing, nitrogen fertilizer is mainly used, supplemented by potassium fertilizer, and the dosage is controlled at about 2-3 kg per year. For peach trees entering the fruiting period, the amount of compound fertilizer should be gradually increased, mainly phosphate fertilizer, supplemented by nitrogen and potassium, and trace elements should be reasonably supplemented according to the specific conditions of oil peach trees. Do the watering work again. There is no need to water in rainy areas, and a certain water content should be maintained in arid areas. The main watering method is small water drip irrigation. When there is too much water, do a good job of drainage to prevent stagnant water from retting the roots.
4. Orchard management
The growth ability of the top branches of nectarine trees is relatively strong, with many branches, and the growth speed of new shoots is also very fast. If it is not suppressed, it is easy to form flower buds. Therefore, we must attach importance to pruning in order to cultivate high-yield trees, control the tree shape, and make reasonable adjustments according to tree potential and plant spacing. Then we should do a good job of intertillage weeding to improve the permeability of soil and prevent weeds from robbing the growth and nutrition of oil peach trees. Create a good growth environment for nectarine trees.
