1. Soil and water: Sandy soil with loose soil and smooth drainage has low demand for water and generally does not need irrigation.
2. Fertilizer: Fertilization in Taoyuan should be comprehensively considered according to the fertility, age, growth and yield of the land.
3. Climate: In winter, the planting temperature of peach trees should not be lower than minus 25 degrees Celsius, and the heat and cooling capacity should not be less.
Fourth, shaping and pruning: during the growth period of peach trees, upright branches or leafy branches should be twisted or cored. It is necessary to prune dense branches and useless branches to improve the ventilation and light-transmitting environment.
5. Continuous cropping: All plots planted with peaches, apricots, plums and cherries are not suitable for planting nectarines, so rotation can be adopted to eliminate the influence of continuous cropping.
6. Flowering management: temperature and humidity management, pollination, flower thinning and branch thinning, and pest control.
1. Soil and moisture Nectarine has certain requirements for soil and is suitable for growing in thick soft soil rich in organic matter. Nectarine has a good root system, likes oxygen and has strong drought tolerance. It is most afraid of waterlogging and water accumulation, but it has strong drought tolerance. Therefore, we should choose sandy soil with loose soil and smooth drainage to build the garden. The soil is sticky, and poor ventilation of root system will limit its growth, which is easy to breed diseases and low yield. The soil pH value is between 4.5 and 7.5, so it can be planted.
Nectarines generally don't need watering. In case of drought in mountainous areas, irrigation 1-2 times can be done as appropriate during the fruit expansion period. Pay attention to cleaning the drainage ditch in rainy season, and pay attention to intertillage and loosening the soil after heavy rain to enhance soil permeability, so as to meet the maximum requirement of oxygen demand for root growth.
Second, the fertilization of fertilizer in Taoyuan should be comprehensively considered according to the fertility, age, growth potential and yield of the land. If the land is fertile, young trees will mainly use organic fertilizer for 3-4 years. Adult trees have high fruit yield, and besides organic fertilizer, nitrogen, phosphorus and potassium fertilizers are also needed. Fertilization time is in the middle and late September of each year, and an annular ditch is dug around the peach tree, which is expanded outward every year to avoid root damage. The ditch is 25-30 cm deep and 30 cm wide. When applying fertilizer, first put phosphate fertilizer at the bottom of the ditch, then apply organic fertilizer, mix well with the soil, fill the ditch, and then irrigate immediately.
The topdressing of peach trees is mainly available fertilizer, and the application period and times are closely related to the growth of peach trees. Topdressing is usually 2-3 times a year. The first time is before flowering, supplement nutrition to ensure good fertilization of peach blossoms and improve fruit setting rate. The second time, before the hard fruit, nitrogen, phosphorus and potassium were used together. Promote the growth and expansion of fruits.
After planting, deep tillage is carried out around the crown every year11-65438+February, and the depth is 20-30 cm, combined with deep tillage and base fertilizer.
