However, while foliar application has many of the advantages described above, there are also application problems, such as how to encourage nutrient elements to pass through the plant leaf surface barrier for rapid and efficient uptake by plants, and so on.
Sophorolipids were first discovered from microbial fermentation products and were initially used primarily as biosurfactants for oil exploitation and product processing as environmentally compatible materials. With the continuous and intensive understanding of people, more and more researches find that sophorolipids have better effects in various aspects of medical anti-inflammatory, disinfection, agricultural antibacterial, growth regulation and the like.

2. Biological assay
Test plants: grape is red earth.
Test agent: medium trace element fertilizers described in examples 1 to 5 and comparative examples 1 to 3.
The test is carried out on a grape planting base in Xinjiang, which is 5-year-old grape, the plant row spacing is 0.8mX3m, and the facility cultivation is conventionally managed. The test is carried out by 8 treatments, each treatment is repeated three times, 24 cells are divided, each cell is arranged randomly, and 50 strains are arranged in each cell. In the test, the test agent is diluted by 200 times by adding water and respectively sprayed once in the leaf spreading period, the pre-flowering period and the young fruit period for three times. The spraying amount of each treatment is the same and is limited by blade dropping.
1. Chlorophyll content determination:
and on the 15 th day after the third spraying, selecting grape leaves with consistent growth conditions of 3-4 sections of basal parts from grape plants which have no plant diseases and insect pests and are normal in each cell row according to a scattered random sampling rule, measuring chlorophyll content by using a SPAD-502 type chlorophyll meter, measuring 10 leaves per cell, measuring 30 leaves per treatment, and taking an average value. The measurement results are shown in Table 1 and FIG. 1.
TABLE 1 Effect of treatments on chlorophyll content of grape leaves
