The cultivation of peach trees is more common and can be cultivated in regions with an average annual temperature of 8-17°C. Peach trees are happy with light and hi dryness. They have strong adaptability to the soil. Generally 2-3 years results, 5-15 years are Fruit period. First, the nutritional characteristics of peach Peach trees absorb roots mainly distributed in 10-30 cm, saplings grow more prosperous, absorption capacity is also strong, if the application of nitrogen fertilizer is more likely to cause nutrient overgrowth, enter the results late, it is easy to cause physiological fruit drop. After the result has reached the peak, the absorption capacity of the root system has been reduced, and the demand for nutrients from the tree has become more. If the supply of nitrogen is insufficient, the tree vigor is easily weakened, the resistance is poor, the yield is low, and the life span is shortened. Therefore, in the nutrition demand of peach trees, the saplings are dominated by phosphate fertilizers, with appropriate amounts of nitrogen and potassium fertilizers, and long-rooted trees. After entering the full fruit period, the focus of fertilization is to coordinate the growth of the branches and the flowering of the peach trees. Nitrogen fertilizer and potash fertilizer are the main fertilizers, and a certain amount of phosphate fertilizer and medium and trace elements are applied. Second, the peach nutrient demand Due to soil fertility, age, variety, yield, climate and other factors, the fertility of the Taoyuan with low soil fertility, high age, and high yield should be higher; the orchard with high soil fertility, small age, and low yield should have adequate fertilization. reduce. The varieties are more resistant to fertilizers, suitable for climatic conditions, and have a higher amount of water for moderate fertilizers. On the contrary, the amount of fertilizers should be appropriately reduced. If the application amount of organic fertilizer is more, the application amount of chemical fertilizer should be less. In general, high-yielding peach orchards contain 18-20 kg of nitrogen (calculated as pure nitrogen), 10-12 kg of phosphorus (calculated as P2O5) and 20-24 kg of potassium (calculated as K2O). For those with less soil and less organic fertilizer, trace elements and fertilizers can be applied as required. Third, the application of fertilizer in fruit period 1. Application of basal fertilizer According to the difference in different varieties of peaches, the fertilizer is applied as soon as possible after the fruit is picked. If the fertilizer cannot be applied in time, it can also be applied about one month before the peach leaves fall. Basal fertilizer is dominated by organic fertilizers. Under the condition of less organic fertilizer, the amount of nitrogen fertilizer can be determined flexibly according to the age of trees, the growth of peach trees, and the fertility of the soil. The application rate of nitrogen fertilizer in general basal fertilizer accounts for about 40-60% of the total annual fertilization, and the fertilization amount per mu is 8-10 kilograms. General phosphate fertilizer is mainly used as basal fertilizer. If more organic fertilizer is applied at the same time, P2O5 per mu equivalent to 10-12 kg. Potassium fertilizer application amount in general basal fertilizer is equivalent to 10-12 kg of K2O. Pay attention not to rely too close to the tree body during fertilization. Fertilizer should be properly mixed with the soil to avoid burning roots. Peach trees with more soil moisture content, soil texture more viscous, older tree age, and weaker tree vigor may use higher values ​​of fertilizer when applying less organic fertilizer, and vice versa. 2. Fertilizer application The flowering fertilizer was applied before flowering in early spring. The fertilizer used was mainly nitrogen fertilizer, which accounted for about 10% of the annual fertilization amount. The combination of irrigation water after spring and spring was carried out at the same time. The nitrogen fertilizer consumption per mu was 2-3 kg in terms of pure nitrogen. If the application rate of basal fertilizer is higher or the basal fertilizer is applied in winter, the application of phytofertilizer may not be applied or reduced. 3. Application of fruit fertilizer The fruit-bearing fertilizers were applied after flowering and before the hardening of the fruit kernels, mainly to increase the fruit setting rate, improve the nutrient of the tree, and promote the rapid growth of the fruit in the early stage. Nitrogen fertilizer is the main fertilizer, with a small amount of phosphorus and potassium fertilizers. The dosage is about 10% of the annual application amount, and the amount of nitrogen fertilizer per acre is 2-3 kg in terms of pure nitrogen. 4. Application of fruit enlargement fertilizer After the fruit was re-entered into the fast-growing period, the fruit enlargement period of mid-late maturing varieties was basically consistent with the flower bud differentiation period. At this time, top-dressing promoted rapid fruit growth, promoted flower bud differentiation, and played an important role in laying the foundation for the next year's production. The fruit enlargement fertilizer is dominated by nitrogen and potassium fertilizers, and a certain amount of phosphate fertilizer can be appropriately applied according to the phosphorus supply status of the soil. The application of nitrogen accounts for about 20-40% of the annual application amount. The amount of nitrogen fertilizer per acre is 6-8 kg in terms of pure nitrogen; the application amount of potassium fertilizer is 10-12 kg in terms of K2O. Peach has less demand for trace element fertilizers, such as organic fertilizers, which can be applied less or less. Organic fertilizers can be used less frequently to apply trace element fertilizers. The actual amount of trace fertilizer (as base fertilizer application) is: 0.25-0.5 kg of borax per acre, 2-4 kg of zinc sulfate per acre, 1-2 kg of manganese sulfate per acre, and 5-10 mg per acre of ferrous sulfate Kilograms, micro-fertilizer can also be foliar spray, spraying the concentration of the leaf according to the degree of aging in the control of 0.1-0.5%, leaves when the tender should be thin, the leaves can be thicker when older.
