By more each experimental group, the parameters such as the growth and development state of cotton and output are evaluated experimental result.Experimental result is in table 7.
Table 7 synergy chelating foliage fertilizer is applied to cotton field experiment
| Experiment group | Experimental group | Control group 1 | Control group 2 | Control group 3 |
| Fruit branch number of units (platform) | 10.5 | 10.1 | 9.7 | 10.2 |
| Dan Zhiling number (individual) | 5.78 | 5.37 | 5.25 | 5.42 |
| Single boll weight (g) | 5.42 | 5.29 | 4.96 | 5.11 |
| Output (kg/667m 2) | 504.01 | 477.79 | 443.28 | 480.31 |
| Stimulation ratio (%) | 13.70 | 7.79 | --- | 8.35 |
From data in table 7, experimental group 1 is compared with control group 1, and fruit branch number of units increases by 3.96%, Dan Zhiling number and increases by 7.64%, and Single boll weight increases by 2.46%, actual volume increase 5.49%; Experimental group is compared with control group 2, and fruit branch number of units increases by 8.25%, Dan Zhiling number and increases by 10.10%, and Single boll weight increases by 9.27%, actual volume increase 13.70%; Experimental group is compared with control group 3, and fruit branch number of units increases by 2.94%, Dan Zhiling number and increases by 6.64%, and Single boll weight increases by 6.07%, actual volume increase 4.93%.Compared with each control group, after spraying under the situation of rain drop erosion, the fertilizer solution of experimental group still effectively can adhere in crop surface, therefore makes the effect of increasing production of cotton clearly, and the indices of cotton all significantly promotes.
In addition, find in experimentation, compared with the process of control group, the Cotton growth of experimental group be good, sickness rate is low, disease resistance is strong, good to the absorbing state of trace element.As can be seen here, using of synergy chelating foliage fertilizer effectively improves output of cotton, cotton anti-adversity and cotton quality, and increasing of quality and production Be very effective is better than other process.
