In recent years, soil testing and formula fertilization has become an important technical measure for fruit tree cultivation. However, some soil testing and fertilizing companies are likely to cause secondary salinization of soil due to differences in fertilizer types during fertilization, which will destroy soil fertility. Soil testing and formula fertilization is not only to coordinate the proportion of nitrogen, phosphorus and potassium. The salt effect index of fertilizer is usually used to express the effect of different fertilizer types on increasing the osmotic pressure of soil solution. All kinds of fertilizers have different salt effect indexes, and their salt accumulation effects after applying them to soil are also different. The greater the salt effect index of the fertilizer, the greater the potential for soil salt damage. The salt-effect efficiencies of superphosphate, diammonium phosphate, and potassium sulphate are 8, 34, and 46, respectively, while the commonly used urea, ammonium nitrate, and potassium chloride have a salt effect index of 75, 105, and 116, which are easily caused in the Huang-Huai-Hai area. Soil salt. Therefore, when formulating fertilization by soil testing, it is necessary to consider the type of chemical fertilizer and its effect on crop growth and development and changes in soil chemical properties. Soil testing and formula fertilization, can not ignore the increase in organic fertilizer in the soil testing formula reasonable application of chemical fertilizers at the same time, appropriate increase in organic fertilizer is an effective measure to prevent and reduce soil surface salt accumulation of important measures, the application of organic fertilizers and organic materials can also increase Change soil structure, increase soil buffering performance, improve soil microflora, increase soil nutrient availability, supplement micronutrients, promote crop root growth, and reduce environmental pollution. Soil testing and formula fertilization methods need to further improve the purpose of fertilization is to compensate for soil nutrient losses and organic matter deficiency. Therefore, in addition to making basic fertilizers, furrowing is a better way and topsoil is wrong. The sprinkler irrigation and drip irrigation that have been popularized in recent years have been applied in the cultivation of facilities, so that the use of fertilizers and water-saving will not easily damage the soil structure and will not cause soil compaction and reduce soil salinization.
