Foliar spray fertilizer is an essential supplementary measure in fruit tree fertilization and has been used as a routine measure in the production of high-quality fruit. Foliage fertilizer nutrients absorbed faster than soil fertilization, can quickly overcome the nutritional symptoms of fruit trees, the use of less nutrient absorption and utilization of high, without the influence of nutrient distribution center, can meet or adjust the fruit tree needs fertilizer critical period of urgent needs, Overcoming the shortcomings of roots to absorb nutrients and increasing fruit yield and quality. Compared with soil fertilization, there is no fixed effect of soil on nutrients, resulting in reduced effectiveness and loss of soil leaching. Calcium nitrate or amino acid calcium fertilizer was sprayed at 6 weeks and 8 weeks after flowering. Spraying calcium chloride or other calcium fertilizers for 10 weeks or 8 weeks could prevent and treat the fruit bitter pit disease and pox spot disease and increase the fruit storage performance. The application of trace elements in the soil makes it easy to fix the soil, and from an economic point of view it is necessary to perform the foliar spray. When the roots of fruit trees are affected by dysplasia, absorption, cold damage, or locust-relief, the foliar spraying can promptly restore the tree vigor. The main problem currently existing in production is that the fruit grower cannot rely on the needs and purposes of the different growth stages of the fruit trees, and targeted selection of appropriate types of leaf fertilizers should be regularly and regularly sprayed. Spraying is less or the spraying method must not be used to achieve the desired results. ? Foliar fertilizer should pay attention to the following matters: 1. Because the liquid fertilizer is mainly absorbed through the back of the leaves with many stomata, so the spray should be meticulous and thoughtful, not only the leaves should be sprayed, and the leaves should be sprayed enough. ? 2. Foliar spraying can be combined with spraying to save labor and improve work efficiency. Care should be taken not to fail with alkaline pesticides such as lime sulfur or Bordeaux mixture. 3. Foliar spraying fertilizer is generally conducted before 10 o'clock in the morning or 4 o'clock in the afternoon or on a cloudy day, avoiding high temperatures, and spraying in a timely manner within 5 hours after spraying. 4. Foliar spray fertilizer should be strictly in accordance with the requirements of the specification. Only a small area of ​​new products can be selected for good effect.
