1、 Experimental product

Sow the same number of wheat seeds (60 seeds) in each group at the same depth, label each group with their respective numbers and fertilizer types. After all the wheat seeds have broken through the soil, fertilize according to the fertilization plan of each group.

2、 Experimental data

Total duration: 3 weeks (adjusted according to plant growth rate), with data recorded twice a week.

Table 1: Growth data of different products

Figure 1: Growth Line Chart of Different Products

According to the chart 1, it can be seen that:

In terms of growth: 

Spirulina extract>fish protein>seaweed extract>competitor 1>competitor2>clean water

Figure 2: Comparison of seedling height after 21 days 

Figure 3: Comparison of root  after 21 days 

Root comparison: The root system of seaweed extract is significantly denser

3、 Experimental conclusion

It can be clearly seen from Figure 1, Figure 2 and Figure 3 that:

（1）Spirulina extract showed the best performance in promoting wheat seedling height and growth;

（2）Comprehensive ranking: Spirulina extract>Fish protein>Seaweed extract>Competitor 1>Competitor2>CK;

（3）In the wheat pot experiment, seaweed extract had the thickest root system.
