By carrying out chemical property detection on cotton surface soil (table 1), the application of the product disclosed by the invention can effectively improve the alkaline soil environment and reduce the water-soluble salt content of the soil. Compared with the comparative example, the pH of the soil is obviously reduced in the examples 4 and 5, and the content of the water-soluble salt is reduced by 23 percent on average, so that the soil environment can be improved by continuously applying the product of the invention, and the cotton is suitable for long-term planting of cotton.
TABLE 1 Effect of different fertilising treatments on surface (0-20cm) soil pH and water soluble salt content
Although the cotton is saline-alkali resistant, the growth of the cotton is still restricted when the soil salinity is high. As can be seen from Table 2, examples 1-5 all improved lint yields to different extents as compared to the comparative examples. In recent two years, the yield of example 4 (the optimal component content of the product of the invention) is increased by 17.26 percent compared with that of the comparative example on average. Examples 1-3 the differences in the factors constituting the yields represent to some extent a synergistic effect between the fish protein powder, the phosphorus activator and the NAM inhibitor. The product of the invention can effectively increase the cotton boll number, the single boll weight and the clothing score, thereby increasing the cotton yield.
TABLE 2 Effect of different fertilization treatments on Cotton yield contributing factors
