The experimental sites were selected from the Red Fuji apple orchards under the general management of Berlin Zhuang in Laiyang City, with a fruit tree density of 1050 Phm2. The soil is brown soil and the soil thickness is 60~80cm. The basic basal fertility of the soil was relatively low. The soil composition analyzer routinely analyzed 0178% organic matter, 1817mg Pkg alkaline nitrogen, 8815mgPkg available potassium, 1916mgPkg available phosphorus, 618mgPkg available sulfur, and 3070mg Pkg and 31617mgPkg exchangeable calcium and magnesium, respectively.
The soil nutrient status analyzed by the soil composition analyzer can be applied to the recommended fertilization of fruit trees to a certain extent, but the adjustment of the CaPMg ratio needs to be considered, especially when the soil already contains sufficient exchangeable calcium and magnesium. More important. The recommended critical ratio of most cropland food crops by the ASI method is 112-612. For apples, 612 should be the lower limit. Because the calcium-magnesium ratio of the tested soil is as high as 818, increasing the amount of calcium in the base application is still effective.
The determination of soil-related elements by the soil composition analyzer was conducted. In view of the fact that the fruit trees are lightly boiled crops, potassium supplements are required to apply potassium sulfate, and the sulfur applied by potassium is sufficient to meet the demand of apple trees in the area. Systematic analysis recommended that the application of halved sulphur fertilizer results in a reduction in single fruit weight, but basically has no effect on quality. Therefore, in the actual field management, sulfur nutrients can not be considered as a limiting factor affecting the quality, but may become a limiting factor in production.
Analysis of Nutrient Requirements of Fruit Trees in Jiaodong Peninsula by Soil Composition Analyzer
The production of fruit trees in the Jiaodong Peninsula has been continuously improved, and the investment in recent years has been continuously increasing. The main fertilizing elements are mainly NPK, and they are also equipped with trace element fertilizers. However, the supply of N fertilizers is often too high in production. It ignores the comprehensive balance of all mineral nutrients. This may be the main reason for the decline in fruit flavor in recent years, so it is of great significance to analyze the relationship between the amount of fertilizer and fruit flavor. A fertilizer effect test for determining the amount of nutrients Ca, Mg, and S was designed to determine whether the middle amount of Ca, Mg, and S has become a limiting factor in apple quality and flavor. The elements in the soil were analyzed using a soil composition analyzer.
