The result of table 12 shows：The administration of soil conditioner can improve soil urease, catalase and invertase
Activity, after soil conditioner continuous administration 2 years, 3 kinds of enzymatic activitys of soil are significantly higher than conventional fertilizer application, so that accelerating soil has
The decomposition and inversion and Organic carbon accumulation of machine material.
The disease-resistant effectiveness experiment of the soil conditioner of the present invention of embodiment 5
In order to preferably verify the disease-resistant effectiveness of soil conditioner of the present invention, it is made using the embodiment of the present invention 1~4
Modifying agent carry out growing tomatoes experiment.
Test material and method
1.1 test periods and place
Test site：Resource and environment institute of Shandong Agricultural University south school foundations of a house reclaimed land experimental plot tomato cultivates base
Ground, kind is bright red No. one.
Test period：In April, 2015~August.
1.2 experimental design
Experiment sets 5 processing, and the conventional fertilizer application of soil conditioner+75% made from embodiment 1~4 is used in processing 1~4 respectively,
Processing 5 is control group, only with conventional fertilizer application, every group of 0.05 mu of experimental plot area, research observation soil conditioner pair of the present invention
The influence of tomato root system root solution nematode population.
The root nodule of tomato plant root is classified according to following standards：
One-level root nodule diameter ＜ 0.17cm；
0.17cm≤bis- grade root nodule diameter ＜ 0.25cm；
0.25cm≤three-level root nodule diameter ＜ 0.3cm；
Level Four root nodule diameter >=0.3cm.
Root nodule numbers measure has been carried out to processing 1~5,1 grade obtained, 2 grades, 3 grades, 4 grades of root nodule numbers result row are determined
In table 13.
Influence of the different disposal of table 13. to tomato root nodule size and number
| Processing | One-level root nodule number/strain | Two grades of root nodule number/strains | Three-level root nodule number/strain | Level Four root nodule number/strain |
| Processing 1 | 13 | 8 | 2 | 0 |
| Processing 2 | 11 | 8 | 2 | 2 |
| Processing 3 | 12 | 6 | 3 | 0 |
| Processing 4 | 12 | 7 | 2 | 0 |
| Processing 5 | 33 | 21 | 16 | 13 |
As can be seen from Table 13：In processing 1~5, the root knot line of the processing of embodiment 1~4 to tomato root invasion
The quantity of worm has obviously reduction effect compared with processing 5, it is possible thereby to illustrate the soil conditioner of the present invention to suppressing
Root-knot nematode is infected with obviously inhibitory action.
Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to limit the scope of protection of the invention with this,
The change and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed scope.
