[0106] Example 1 : Effect of the tomato disease-resistant fertilizer composition of the present invention on the number of tomato root rhizolytic nematodes
[0107] A. Materials
[0108] fertilizer:
[0109] Use the tomato disease-resistant fertilizer composition of the present invention.
[0110] The composition of the tomato disease-resistant fertilizer composition of the present invention of different treatments is listed in Table 1:
[0111]
[0112]
[0113] CK in the table represents the control fertilizer, and the tomato disease-resistant fertilizer composition of the present invention used in this embodiment is a powder.
[0114] B. Test soil
[0115] The test soil was collected from the severely diseased soil in the vegetable field of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences. figure 1 . When the tomato seedlings were planted (March 29), the growth potential was investigated, and the plant height, stem dia...
Embodiment 2
[0141] Example 2 : Effect of tomato disease-resistant fertilizer composition of the present invention on tomato biomass
[0142] A. Materials
[0143] fertilizer:
[0144] The tomato disease-resistant fertilizer composition of the present invention used in Example 1 was used.
[0145] See Table 1 for the composition (in parts by weight) of the tomato disease-resistant fertilizer composition of the present invention with different treatments.
[0146] The tomato disease-resistant fertilizer composition of the present invention used in this embodiment is a powder.
[0147] B. Test soil
[0148] The test conditions are the same as in Example 1.
