In recent years, the phenomenon of excessive flowering, less fruit set, and poor economic efficiency are frequently seen in the production of fruit trees. The reasons for this are analyzed. In addition to the large amount of pruning, resulting in poor scenery and conditions, the main reason is that the basal fertilizer is not applied on time. As a result, the nutritional level of fruit trees is low, resulting in low fruit setting rate. Therefore, applying basal fertiliser in autumn to improve the nutritional level of fruit trees is the basis for high yield and quality. Organic fertilizers are used as base fertilizers, including ring fertilizer, cow dung and chicken manure. These fertilizers contain nutrient elements of relatively complete types (such as nitrogen, phosphorus, potassium, sulfur, calcium, magnesium, zinc, iron, manganese, boron, copper). Besides, it also contains a lot of organic matter, which can not only basically meet the needs of fruit trees for various nutrients, but also improve the soil, enhance soil fertility, and improve fruit quality. Basal fat is best for basal fertilization, and it is generally controlled about 1 month before the defoliation of fruit trees, that is, around National Day. This is the third peak of fruit tree root growth. The roots of fertilization are easy to heal and can promote a large number of new roots. In addition, the fertilizer is easily decomposed and is conducive to root absorption. Stop growing, and its newly absorbed nutrients are mainly accumulated reserves, which can increase the nutrient level of the tree, thus enhancing the ability to resist cold. The storage nutrition of fruit trees plays an important role in the annual cycle of fruit trees. It has a direct impact on the wintering and late spring sprouting, flowering, fruit setting, leaf spreading, and rooting of the tree. The size of the fruit depends on the number of cells and the size of the cells. The number of cells depends on the nutritional level of the reserve. The size of the fruit depends on the nutritional status of the tree in the year. Therefore, if the nutrients in the tree reserve are insufficient, the fruit will be flattened. When the nutrient is poor, the fruit will grow longer and the fruit type index will be larger. While applying organic fertilizer, some quick-acting fertilizers (such as nitrogen, phosphorus, potassium, zinc, iron, magnesium, etc.) are added to improve tree resistance and improve flower bud quality. The amount of fertilizer absorbed by fruits increased with the increase of fertilizer in a certain range, beyond a certain range, the amount of fertilizer increased and the absorption decreased. Fruit tree species, different varieties, the need for fertilizer is not the same, the deciduous fruit trees generally apples, grapes need the largest amount of fertilizer, juvenile tree needs less fertilizer, the tree results in more trees should be more than appropriate, especially multi-phosphorus Potash fertilizer. The fertility of the soil is different, and the amount of fertilizer is not the same. In general, the result of the park is two-for-one, ie, 0.5 kg of fruit and one kilogram of fertilizer, in order to achieve the purpose of high yield and quality of strong trees. There are two main methods for the production of basal fertilizer. One is the ring fertilization method: dig a 30-60 cm wide and 30-50 cm deep ditch under the outer edge of the canopy and mix the fertilizer and soil. Ditch, then cover the soil. This method is suitable for young trees with smaller root distribution. The second is the strip fertilization method, with the canopy size as the standard, open 1-2 furrows between fruit trees or between lines, the furrows are 50-70 cm wide, 30-50 cm deep, and the fertilizer and soil are mixed and scattered in the furrows. Cover the earth; the ditch can be used annually for rotation. This law applies to the big trees in the result period. After the fertilization, it is necessary to pour water once to make the soil fertilizer and the root system close. (Source: Fruit Tree Technology and Information)
