As is well known, 5-ALA can not only improve the quality of agricultural products, but also significantly increase their yield. This is currently a biosynthetic stimulant that can simultaneously improve the quality and yield of agricultural products. The emergence of Pre C has truly made up for the instability of 5-ALA, achieving long-term and multi effect effects.

2.4 Test method

The test site is greenhouse No. 13 of Shuibantian Experimental Farm, and the previous stubble is wasteland. On March 1, 2023, small green vegetables will be transplanted, with 1.2 m ridge spacing and 20 cm plant spacing. The first leaf spraying fertilization treatment (see the table below for the specific treatment) will be carried out on March 8, 2023 at the five leaf stage (GS=15) of the seedling stage of Brassica campestris after a week of slow seeding. The same treatment will be carried out again every seven days later, with a total of three times of fertilization. The chlorophyll content of Brassica campestris will be investigated four days after each fertilization. After the second treatment, the leaf area, fresh weight above ground and root weight of the plant will be investigated, and the yield will be calculated. The data will be recorded for statistical analysis.

Table Test Processing

A total of 5 treatments were designed for the experiment, with each treatment repeated 4 times, totaling 20 residential areas with an area of 1.2 meters × 3 m=3.6 m2.

3. Experimental data and analysis

3.1 Effect of Different Fertilizers on Chlorophyll Content of Small Green Vegetables

Effect of Different Fertilizers on Chlorophyll Content of Small Green Vegetables

Note: The data in the above table are the average values of each repetition, the same below.

The data in the table above shows that compared to the control of water spraying on the leaves during the seedling stage, the Xiaotaiyang Pre-C and other treatment schemes have a significant impact on the chlorophyll content of small green vegetables. Among them, treatment 4 can significantly increase the chlorophyll content by 3.17%, with significant differences.

From the above figure, it can be seen that compared to the water control treatment, the treatment of 4 red fruit strength 800 times can significantly increase the chlorophyll content of small green vegetables in the early stage, while the treatment of 2 small sun pre C can significantly increase the chlorophyll content of small green vegetables in the later stage, with significant differences between treatments.

3.2 Effect of Different Fertilizers on Leaf Area of Small Green Vegetables

The effect of different fertilizers on the leaf area of small green vegetables

The data in the table above shows that compared to the water control during the seedling stage, foliar spraying treatment 2 and other treatment schemes can increase the leaf area of small green vegetables. Among them, treatment 2, Xiaoyang Pre-C, has the best fertilizer effect, which can significantly increase 26.66%. The second best fertilizer effect is treatment 4, which has 800 times the fruit strength, and treatment 5, which has 150 times the Dengji, which has significant differences compared to the water control. The other groups have significant differences.

From the above figure, it can be seen that compared to the control with clear water, the use of different fertilizers can significantly increase the leaf area of small green vegetables. Among them, treatment 2, Xiaoyang Pre-C, has the best fertilizer effect, followed by treatment 4, which has the best fertilizer effect. The fertilizer effect of early autumn red is 500 times slightly higher than that of red fruit strength 800 times, indicating a significant difference.

3.3 Effects of different fertilizers on the aboveground fresh weight of small green vegetables

Table The Effect of Different Fertilizers on the Fresh Weight of Small Green Vegetables on the Ground

The data in the table above shows that compared to the clear water control during the seedling stage, foliar spraying with Little Sun Pre-C and other treatment schemes can increase the aboveground fresh weight of small green vegetables. Among them, treatment 2 with Little Sun Pre-C has the best fertilizer effect, which can increase by 25.30%. Secondly, treatment 4 with 800 times the red fruit strength has the best fertilizer effect, and both have significant differences compared to the clear water control, but the difference between the two is not significant.

As can be seen from the above figure, the use of different fertilizers can increase the aboveground fresh weight of small green vegetables compared to the control with clear water. In the later investigation, treatment 2 Xiaoyang Pre-C and treatment 4 Hongguo Li 800 times better fertilizer efficiency, with treatment 2 Xiaoyang Pre-C slightly higher than Hongguo Li 800 times. Compared to other treatment schemes with clear water, the fertilizer effect is significant.

3.4 Effect of Different Fertilizers on Root Weight of Chinese Cabbage

The data in the above table shows that compared to the control with clear water, the root weight of small green vegetables can be increased in one survey. Among them, treatment 3 with 500 times of early autumn red can significantly increase by 9.23%, and the difference is not significant. The second investigation showed that the treatment of 2 Xiaosun Pre-C and 4 Hongguo Li increased the root weight of small green vegetables 800 times, while other treatment schemes reduced the root weight of small green vegetables, with significant differences among the treatments.

From the above table, it can be intuitively seen that compared to the water control treatment, treatment 4 with 800 times the red fruit strength has better fertilizer efficiency. In the later stage, it can increase the root weight of small green vegetables, but the fertilizer efficiency is slightly lower than treatment 2 with small sun Pre-C.

3.5 Effect of Different Fertilizers on Nitrate Content of Small Green Vegetables

The data in the table above shows that compared to the control of water, the use of Xiaotaiyang Pre-C and other treatment schemes in foliar spraying during the seedling stage reduced the nitrate content of small green vegetables. Among them, the treatment of 5 deng chicken and 15 times of explosive red had the best fertilizer effect, reducing 8.79%, but the difference was not significant.

As can be seen from the above figure, compared to the water control group, other schemes all reduced the nitrate content of small green vegetables, among which the effect of Small Sun Pre-C was more obvious.

3.6 Effects of different fertilizers on the yield of small green vegetables

The data in the table above shows that compared to the control group with clear water, spraying Xiaoyang Pre-C on the leaves during the seedling stage and other treatment schemes can improve the yield of small green vegetables. Among them, treatment 2 Xiaoyang Pre-C has the best fertilizer efficiency, which can increase by 23.11%, and the difference is significant; Secondly, the treatment of 4 red fruits with 800 times more fertility is more effective.

From the above figure, it can be intuitively seen that compared to the control of water, spraying other treatment schemes on the leaves of small green vegetables during the seedling stage can improve yield, among which the treatment of Small Sun Pre-C has the best effect.

4. Test results and discussion

4.1 Compared to the control of water, spraying Xiaosun Pre-C and other treatment schemes on the leaves of small green vegetables during the seedling stage can increase the leaf area, aboveground fresh weight, and yield of small green vegetables, and have a certain impact on the chlorophyll content, root weight, and nitrate content of small green vegetables, with significant differences;

4.2 Compared with the water control, the small sun Pre-C can increase leaf area by 25.76%, aboveground fresh weight by 25.06%, and yield by 16.29%, with significant differences.

Compared to the clear water control, spraying small green vegetables on the leaves of Xiaoyangpre C during the seedling stage has better fertilizer efficiency, greatly increasing the leaf area of small green vegetables by 26.66%, aboveground fresh weight by 25.30%, and yield by 23.11%, with significant differences.

In summary, spraying Little Sun Pre-C on the leaves of small green vegetables during the seedling stage has better fertilizer efficiency, which can significantly increase the leaf area and aboveground fresh weight of small green vegetables. The analysis of quality indicators of small green vegetables showed that compared to the control with water, other treatment schemes could reduce the nitrate content in small green vegetables leaves, with significant differences; Moreover, the fertilizer efficiency of treatments 3, 4, and 5 applied alone was slightly lower than that of the Xiaotaiyang Pre-C control. In the second survey, it was found that the fertilizer efficiency indicators of treatments 3, 4, and 5 had decreased, indicating a decrease or partial failure of the content of effective substances such as 5-ALA. It has also been proven that Pre-C plays a significant role in the stability of 5-ALA.
