Embodiment 1

[0050] The sampling site of this example is the Puyuan Vegetable Gardening Cooperative (Huangqiao Base) in Songjiang District, Shanghai. There are 300 facility greenhouses in the base, and the vegetables grown are mainly green leafy vegetables such as green vegetables, Chrysanthemum chrysanthemum, and lettuce. Sampling units were divided according to crop and shed age, and a total of 60 soil samples were collected, and the salinity (main index), alkaline nitrogen, available phosphorus, and available potassium (auxiliary index) of the soil samples were measured and graded. The classification results are shown in the table 2, and draw a soil salinity grading map according to the salinity content in the soil sample. On the plan of the cooperative, yellow, green, orange, and red are used to represent the lack, medium, high, and excess field units respectively. In this embodiment, the soil A schematic diagram of the salt classification diagram is shown in figure 2 shown.

Embodiment 2

[0059] The sampling location of this example is the vegetable area of ​​Shanghai Mingyuan Cooperative, where there are more than 50 facility greenhouses, and the vegetables grown are mainly solanaceous vegetables such as tomatoes and cucumbers. Sampling units were divided according to crop and shed age, and a total of 30 soil samples were collected. The salinity (main index), alkaline nitrogen, available phosphorus, and available potassium (auxiliary index) of the soil samples were measured and graded. The classification results are shown in Table 5. As shown, and draw a soil salinity grading map according to the measured salinity content in the soil sample, on the cooperative plan, use yellow, green, orange, and red to represent the lack, medium, high, and excess field units respectively. In this embodiment Schematic diagram of soil salinity grading diagram in image 3 shown.

[0060] It can be seen from Table 5 that according to the investigation results of the background v...

Abstract

The invention discloses a soil testing and formulated fertilization method for vegetables. The method comprises following steps: collecting a soil sample of a vegetable planting field, and measuring content of salt, nitrogen, phosphorus and potassium of the soil sample; and performing salt content grading and nitrogen, phosphorus and potassium grading on the vegetable planting field respectively according to the content of salt, nitrogen, phosphorus and potassium; determining a fertilization formula of the vegetable planting field according to the nitrogen, phosphorus and potassium grading; and determining the fertilization amount of the vegetable planting field according to the salt grading. The soil testing and formulated fertilization method for vegetables is simple, easy and clear, hashigh operability and is easily mastered and popularized by farmers.

Description

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