In the cultivation and management of the annual cycle of apple trees, the accumulation of nutrients is promoted, and the inefficient consumption of nutrients should be minimized. These two aspects are effective cultivation management measures for obtaining high yield of apples. The following management measures should be taken: First, the root system of the root tree is the main organ that absorbs inorganic nutrients and water. The inorganic nutrients supplied by the soil to the fruit are absorbed through the roots of the tree. To raise the roots and make the roots grow well, it is necessary to create a good soil environment for root growth and development. Such as: First, to maintain the stability of soil moisture, can not be wet and dry, drought, watering, 3 to 4 days of surface capillary root death, and then regenerate new roots; Second, stabilize the soil's pH, so that the soil pH is suitable for fruit trees In the range of growth results, too high and too low is not conducive to the normal growth and absorption of roots; the third is to increase the application of organic fertilizers, reduce the amount of chemical fertilizers, create a harmonious environment for the soil, and make the various elements in the soil in a harmonious state and promote The growth and absorption of roots; the fourth is to eliminate soil diseases, reduce the harmful bacteria in the soil, create a good environment for the roots, and promote the robust growth of the roots. Second, improve the soil, weeding and weeding, prevention and control of pests and deep lands, sand and soil change, improve soil aggregate structure; deep excavation of planting points, planting orchards, tree shrubs, all to create a good root environment. In the growing season of fruit trees, after the weather is raining or after watering the trees, timely weeding and weeding and protecting the grass; controlling pests that endanger the roots and protecting the normal growth of the roots are all management tasks that must be done in time. Third, increase soil organic matter Many orchards have low soil organic matter content. To make fruit trees grow robustly, early results, high yield, stable yield, and high efficiency, the organic matter content of orchard soil should reach 2% to 3%, at least 1.5%. Increasing the soil organic matter content is an effective way to increase the nutrition of fruit trees. It is an effective measure to increase soil organic matter content by planting grass, planting trees, and applying organic fertilizer. Organic fertilizer can be mixed with beef, sheep, pig and chicken manure for fermentation, and it can be fully fermented (especially chicken manure must be fully decomposed), and appropriate amount of chemical fertilizer and mineral fertilizer (multiple trace elements) can be added. And biological fertilizer. 300-500 kg of straw carbon per acre (that is, the straw is burned like charcoal to form a carbon ash), and the soil organic matter can be increased to about 1.5 in three years. 4. Scientific fertilization Scientific fertilization not only promotes the growth of fruit tree roots, but also plays an important role in increasing nutrient accumulation and growth and development of trees in the later stage of growth. To increase the nutrient accumulation of the tree, it is necessary to apply organic fertilizer when applying the base fertilizer in the early autumn. The base fertilizer can not be applied too late, it should not be applied too deep, do not apply too much nitrogen fertilizer, pay attention to the reasonable ratio, combined with phosphorus and potassium fertilizer, and should apply appropriate amount of trace element fertilizer. Fertilization can be applied with a sufficient amount of decomposed organic fertilizer, and a special fertilizer for fruit trees can also be applied. Organic fertilizer and inorganic fertilizer should be combined and applied. It is necessary to pay attention to the nutrient balance of the tree body, and it is better to measure the soil and fertilize the formula. Fertilization should be carried out according to the needs of fruit trees, and scientific fertilization time, type of fertilizer and fertilization amount should be mastered for fertilization. If the time of fertilization is not right, the type of fertilizer is wrong, and the amount of fertilization is improper, it will break the normal growth rule of fruit trees, and many problems and contradictions will occur. According to the different development stages of the apple tree, the type, quantity and fertilization frequency of the applied fertilizer were determined. In the annual growth cycle of fruit trees, it is necessary to determine the type of fertilizer, the number of times, the type of fertilizer applied and the amount of fertilizer applied according to the law of fertilizer requirements and the growth of the tree. Pay attention to the scientific fertilization, in addition to the nutrients in addition to the growth and development of fruit trees, but also can accumulate. 5. Protecting the organic nutrients required for the growth and development of leaf fruit trees is a product of photosynthesis through leaves. There must be sunlight for photosynthesis. Therefore, in order to increase and accumulate rich organic nutrients, it is necessary to maximize the illumination of the tree leaves to ensure that the tree has sufficient and sound, but not too much, resulting in a canopy per plant or The leaves of the whole orchard are closed. It is necessary to protect the long and thick leaves, the dark green color, the complete leaves, and the leaves are not damaged by pests and diseases. Many orchards only pay attention to the previous pest control and leaf conservation work, but neglect the leaf protection measures in the later period (after the end of July), causing the early leaves and leaves of the fruit trees to be serious, forming large and small years, even for three or four years without results. In fact, the apple tree formed no more than 10% of flower buds before July 15. A large number of flower buds are after August, and the quality of flower buds is September and October. Therefore, the later work of pest control and leaf protection is very important. It directly affects the output and quality of the year, and also affects the quantity and quality of flower buds next year. It must not be ignored.
