Embodiment 1

[0050] The sampling location in this example is Puyuan Vegetable Gardening Cooperative (Huangqiao Base), Songjiang District, Shanghai. There are 300 greenhouses in the base, and the vegetables grown are mainly green vegetables such as green cabbage, chrysanthemum and lettuce. Divide the sampling units according to the crop and the age of the shed, and collect 60 soil samples in total, and measure and classify the salinity (main index), alkaline hydrolyzable nitrogen, available phosphorus, and available potassium (auxiliary index) of the soil samples. The classification results are shown in the table. 2, and draw a soil salinity grading map according to the salt content in the soil samples. On the cooperative plan, yellow, green, orange, and red are used to represent the lack, medium, high, and excess field units. In this example, the soil The schematic diagram of the salt classification diagram is as follows: figure 2 shown.

Embodiment 2

[0059] The sampling location in this example is the vegetable area of ​​Shanghai Mingyuan Cooperative. There are more than 50 greenhouses in the area, and the vegetables grown are mainly tomato, cucumber and other solanaceous vegetables. Divide the sampling units according to the crop and the age of the shed, and collect 30 soil samples in total. The salinity (main index), alkali-hydrolyzed nitrogen, available phosphorus, and available potassium (auxiliary index) of the soil samples are measured and graded. The classification results are shown in Table 5. The soil salinity grading map is drawn according to the measured salinity content in the soil samples. On the cooperative plan, yellow, green, orange, and red are used to represent the lack, medium, high, and excess field units, respectively. This example The schematic diagram of the soil salinity grading map is as follows image 3 shown.

[0060] As can be seen from Table 5, according to the survey results of the background...

Abstract

The invention discloses a method for soil testing and formula fertilization for vegetables. The method includes the following steps: collecting soil samples from vegetable planting sites, and measuring the salinity, nitrogen, phosphorus and potassium contents of the soil samples; , phosphorus and potassium content respectively carry out salt classification and nitrogen, phosphorus and potassium classification to described vegetable planting ground; Determine the fertilization formula of vegetable planting land according to described nitrogen, phosphorus and potassium classification; Determine the fertilization formula of vegetable planting land according to described salt classification The amount of fertilization; the method for formula fertilization by soil testing for vegetables is simple and easy to implement, simple and clear, and has strong operability, which is convenient for farmers to master and popularize.

Description

technical field [0001] The invention relates to the technical field of vegetable cultivation, in particular to a soil-testing formula fertilization method for vegetables. Background technique [0002] Soil testing and formula fertilization technology is an important measure to ensure high-quality and high-yield crops, efficient use of fertilizers, and protection of the ecological environment. As a source of various nutrients for the human body, the research on soil testing and formula fertilization technology has attracted extensive attention. According to the law of vegetable fertilizer demand, soil fertilizer supply performance and fertilizer effect, soil testing and formula fertilization can achieve its high yield, high quality, high efficiency, high efficiency and high efficiency. The purpose of environmental protection is of great significance to the sustainable development of the vegetable industry. [0003] Soil testing and formula fertilization is a comprehensive ap...
